Connecticut Cannabis Packaging Regulations: A Complete Guide

Connecticut cannabis packaging requirements apply to the complete package and vary by product type, market, serving configuration, and potency. A compliant package must do more than use a child-resistant closure. Businesses must coordinate package performance, appearance, labeling, testing, product registration, and responsible-material decisions.

Under Connecticut's current adult-use cannabis policies, consumer packaging must generally be child-resistant, tamper-evident, entirely and uniformly opaque and light-resistant, impervious, and entirely and uniformly one color. Edible cannabis packaging and labels generally must be entirely and uniformly white. Final packaging may also need stability testing in the specific type and size used for sale.

The following information reflects Connecticut law and the Department of Consumer Protection's policies and guidance, as of August 25, 2026. Cannabis requirements are time-sensitive and should be rechecked before they are applied.

Connecticut Cannabis Packaging Requirements at a Glance

Businesses preparing cannabis for the Connecticut market should confirm that the complete product and package satisfy the requirements that apply to the intended market and product form.

Consumer packaging must generally:

• Satisfy the applicable federal child-resistant special-packaging standard.
• Be tamper-evident.
• Be entirely and uniformly opaque and light-resistant.
• Be impervious and protect the cannabis from contamination.
• Be entirely and uniformly one color.
• Carry the required product, cannabinoid, warning, symbol, serving, and traceability information.
• Meet the additional requirements for the product's form, potency, serving configuration, and market.
• Use the specific package type and size covered by the required stability testing.

Packaging and labels for edible cannabis products must generally be entirely and uniformly white. Additional rules apply to cannabis beverages, multi-serving edibles, high-potency products, delivery device cartridges, internal packaging, and products sold through the medical marijuana program.

The following sections explain how Connecticut's package-performance, appearance, labeling, product-specific, testing, registration, and responsible-material requirements work together.

Child-Resistant, Tamper-Evident, Light-Resistant, and Impervious Packaging

Connecticut treats child resistance, tamper evidence, light resistance, and contamination protection as separate packaging requirements. Satisfying one requirement does not establish that the package satisfies the others.

Child-Resistant Cannabis Packaging

Cannabis packaging must satisfy the federal definition of “special packaging” in 16 CFR 1700.1(b)(4). Special packaging is designed or constructed to be significantly difficult for children under 5 years old to open or obtain a harmful amount of its contents within a reasonable time, while remaining usable by adults.

Child-resistant does not mean child-proof. A package should not be described as compliant solely because it is difficult to open, uses a push-and-turn closure, or resembles another child-resistant package.

Businesses should confirm that the supporting testing and documentation apply to the complete configuration being used, including:

• The container size and material.
• The closure and child-resistant mechanism.
• Liners, seals, inserts, and other components.
• Whether the package was evaluated as reclosable or single-use.
• The filling, closing, sealing, and assembly procedures.
• Any opening and closing instructions required for proper operation.
• Whether the cannabis or another package component could interfere with the closure.
• Whether the package must retain its child-resistant performance through repeated use.

A change to the container, closure, liner, seal, material, or any other component may result in a configuration not covered by the original testing or documentation.

Packaging for a product intended for multiple servings must be resealable, continuously child-resistant, and capable of preserving the integrity of its contents. The child-resistant function must therefore continue to operate after the consumer opens and recloses the package.

The U.S. Consumer Product Safety Commission does not approve or endorse individual packages, manufacturers, or testing firms. The finished-product manufacturer is responsible for selecting packaging that is appropriate for the product and confirming that the applicable requirements are met. Review the CPSC’s Poison Prevention Packaging Act business guidance when evaluating child-resistant documentation.

Tamper-Evident Packaging

Connecticut’s current policies define packaging as tamper-evident when it has one or more indicators or barriers to entry that prevent the contents from being accessed or adulterated without making it apparent to a reasonable person that the package has been breached.

Depending on the package configuration, tamper evidence may involve a seal, band, film, tear strip, breakaway feature, liner, or another component. The selected feature should be evaluated after the package has been filled and assembled.

A tamper-evident component should:

• Provide visible evidence when the package has been opened or breached.
• Remain intact through ordinary filling, handling, transportation, and retail display.
• Be positioned so the consumer can evaluate it before opening the package.
• Avoid interfering with the child-resistant mechanism.
• Be compatible with the container, closure, product, and expected storage conditions.

A child-resistant closure does not necessarily reveal prior opening. Similarly, a tamper-evident seal or band does not automatically make the package child-resistant.

Light-Resistant and Impervious Packaging

Connecticut defines light-resistant packaging as packaging that is entirely and uniformly opaque and protects all of its contents from the effects of light.

The entire package configuration should be evaluated. Applying an opaque label to only part of a transparent container should not be assumed to satisfy the requirement if the remaining portion of the package allows light to reach the product.

Packaging must also be impervious and protect its contents from contamination and exposure to toxic or harmful substances. The requirement specifically extends to glue, adhesive, and other substances incorporated into the package.

Package development should therefore account for:

• Compatibility between the cannabis and the container, closure, liner, seal, and adhesive.
• Migration, absorption, swelling, cracking, corrosion, or other material changes.
• The product’s oils, solvents, flavors, ingredients, and moisture content.
• Seal integrity and barrier performance.
• Filling temperatures and application conditions.
• Expected storage, transportation, and shelf-life conditions.
• The potential for labels, inks, adhesives, or decorations to come into contact with or contaminate the product.

Compliance should be evaluated using the finished package and the intended cannabis product. Performance demonstrated with an empty container or a different formulation may not establish that the complete system is suitable.

Packaging Cannabis for Transportation

Different requirements apply when cannabis is transported between cannabis establishments before it has been placed in final consumer packaging.

Cannabis flower, cannabis trim, and cannabis products that are not in final packaging must be sealed in an airtight manner using packaging material that is both tamper-evident and light-resistant.

Transportation packaging should not be treated as a substitute for the final consumer package. Before sale or transfer to a consumer, qualifying patient, or caregiver, the cannabis must be placed in the applicable final packaging and carry the required label.

Review Section 21a-421j-31 of Connecticut’s current Regulation of Adult Use Cannabis policies and procedures before approving a consumer or transportation package.

Connecticut Package Appearance and Design Restrictions

Connecticut restricts the appearance of both cannabis packaging and labeling. These requirements apply in addition to the package-performance standards.

Cannabis packaging must generally:

• Be entirely and uniformly one color.
• Contain no information, printing, embossing, debossing, graphics, or hidden features other than labeling expressly required or permitted by the applicable rules.
• Avoid visual similarity to a commercially similar product that does not contain cannabis.
• Avoid packaging used for goods marketed to an audience reasonably expected to be younger than 21.

These restrictions should be considered when selecting the container and when developing the label. A package can raise concerns through its shape, color, finish, structure, graphics, product name, imagery, or overall resemblance to another consumer product.

Edible Cannabis Packaging and Labels

Packaging for edible cannabis products must be entirely and uniformly white. Labels on edible cannabis products, including cannabis beverages, must also be entirely and uniformly white.

Required and permitted black label information may still appear on the white label. The rules also provide limited treatment for required warnings and an allowable picture of the cannabis product. A logo appearing on an edible cannabis product label must be black.

Connecticut provides a narrow exception for certain liquid products. A liquid containing cannabis may be packaged in an aluminum-alloy bottle or can when:

• The bottle or can contains at least eight fluid ounces.
• The container does not incorporate color through painting, dyeing, anodizing, or another method.
• The complete package continues to satisfy the other applicable packaging and labeling requirements.

The use of uncolored aluminum does not remove the requirements concerning child resistance, tamper evidence, light resistance, contamination prevention, serving limits, or labeling.

Permitted Product Picture

A cannabis package may carry one picture of the cannabis contained inside it.

The picture must:

• Clearly depict the cannabis product’s size, shape, and color.
• Not obscure or overlap any required information.
• Measure no more than one inch high by one inch wide.

This permission is limited to a picture of the actual cannabis product. It should not be interpreted as general permission to use illustrations, characters, lifestyle imagery, decorative graphics, or pictures of unrelated ingredients and products.

Permitted Cannabis-Establishment Logo

The label may feature a single logo associated with a cannabis establishment.

The logo must:

• Use no more than three colors, excluding black and white from the count.
• Not obscure or overlap required label information.
• Measure no more than one inch high by one inch wide.

A logo on an edible cannabis product label may only be black.

The logo must also comply with Connecticut’s restrictions on appealing to people younger than 21. Permission to display a logo does not override the state’s broader restrictions on youth appeal, product resemblance, registered product names, or prohibited promotional content.

Internal and External Packaging

Separate internal packaging may be used when needed to satisfy the child-resistant, tamper-evident, light-resistant, and impervious packaging requirements.

When qualifying internal packaging is used:

• The internal package must carry the information required by the applicable internal-labeling provision.
• The external package must satisfy the requirements applying to the complete consumer package.
• The internal and external packaging must use the same single uniform color.
• Both layers remain subject to the applicable labeling and design restrictions.

Adding an outer carton, pouch, sleeve, or other secondary component can therefore create additional requirements. It should not be treated as unrestricted branding space or added after the primary package and label have been approved without further review.

Package structure and artwork should be reviewed together. The container, closure, liner, seal, internal packaging, external packaging, label, product picture, logo, symbols, warnings, and product name can combine to create an overall presentation that requires additional compliance review.

Review the packaging and labeling provisions in Chapter 420h of the Connecticut General Statutes and Sections 21a-421j-31 and 21a-421j-32 of the Department’s current adult-use cannabis policies and procedures before approving a package design.

Required Connecticut Cannabis Label Information

Before cannabis is sold or transferred to a consumer, qualifying patient, or caregiver, the package must carry the information required by Connecticut’s labeling rules.

The core information must be printed directly on the packaging or applied through a separate label. An extended-content label, package insert, or QR code cannot replace the information that Connecticut requires on the primary package label.

The core label must include the unique identifier generated through the Cannabis Analytic Tracking System. Other required information must generally be presented:

• In legible English.
• In black Times New Roman font.
• In a flat, regular typeface.
• Against a contrasting background.
• In a uniform size of at least one-tenth of an inch, measured using a capital letter “K.”

The same required product information must also be available on the website of the cannabis establishment that sells the product.

Depending on the product, the core label must identify:

• The product name registered with the Department.
• The cannabis establishment that manufactured the final cannabis product or cultivated the raw cannabis.
• The expiration date.
• Net weight or volume in both metric and imperial units.
• The standardized serving size and number of servings when applicable.
• Directions for use and storage.
• The range of time it typically takes for the product to take effect in a person.
• Each active ingredient comprising at least 1% of the cannabis.
• Applicable cannabinoid and other active-ingredient quantities.
• Known allergens identified by the U.S. Food and Drug Administration or the required statement when no such allergens are known.
• The required health and safety warnings.
• The applicable chemotype.
• Any additional product-specific warning required by the Commissioner.
• Any additional information required under the state or federal labeling laws applying to comparable products that do not contain cannabis.

The label should be developed using the final product formulation, laboratory results, registered product information, serving configuration, and intended package. Placeholder cannabinoid values, serving information, or expiration dates should not be carried into finished artwork without verification.

Expiration Dates and Storage Information

The label must include an expiration date. Connecticut specifies that the expiration date cannot account for refrigeration after the product has been sold to a consumer, qualifying patient, or caregiver.

The package must also provide storage instructions. Storage instructions, the stated expiration date, stability-testing results, packaging materials, and expected distribution conditions should be reviewed together.

Changing the type or size of final packaging may require stability testing to be performed again. A package with different barrier properties, headspace, closure performance, or product-contact materials may not support the expiration date established using the prior configuration.

Serving and Cannabinoid Information

When applicable, the label must state the standardized serving size in customary units and the number of servings in the package.

The label must also provide the required active-ingredient information. This includes each active ingredient comprising at least 1% of the cannabis, along with the applicable quantities in metric units and percentages.

Chapter 420h separately requires amounts and concentrations of THC and CBD per serving and per package to be clearly identified. The label values should match:

• The product’s Certificate of Analysis.
• The registered product information.
• The total contents of the package.
• The standardized serving size.
• The number of servings.
• Any individual-unit or activation information required for the product.

For an edible product, the serving information must also align with Connecticut’s 5-milligram standard-serving limit, 100-milligram multi-serving package limit, and applicable demarcation and separation requirements.

Connecticut Cannabis Warnings, Symbols, and Chemotypes

Connecticut requires multiple health and safety elements on cannabis labels. These elements are separate from the product name, ingredient, cannabinoid, serving, and traceability information.

Primary Warning Statement

The label must display the prescribed primary warning inside a red box.

The required warning addresses:

• The product’s lack of FDA approval.
• Potential intoxication.
• Possible long-term physical and mental health effects.
• Delayed effects.
• The prohibition against operating a vehicle or machinery while under the influence.
• The need to keep cannabis away from children.

Businesses should reproduce the current required text directly from the Department’s policies rather than recreating or paraphrasing it in finished artwork.

Rotating Warning Statements

The core label must also carry at least one of Connecticut’s four additional warning statements. These warnings address:

• Mental-health and developmental risks associated with frequent and prolonged use.
• Cannabis use during pregnancy or breastfeeding.
• Intoxication, habit formation, and addiction.
• Adverse effects that may result from consuming more than the recommended amount.

The applicable warnings must be rotated quarterly on an alternating basis. Artwork-control procedures should therefore identify:

• Which warning appears on each version of the label.
• The calendar quarter assigned to each version.
• The inventory of labels carrying each warning.
• The date on which production changes to the next warning.
• How obsolete or out-of-cycle artwork will be controlled.

A single permanent warning should not be used for every production period that requires quarterly rotation.

The extended-content information discussed below must provide all four warning statements, even though the primary package label rotates among them.

THC and Age Symbols

Connecticut requires two Department-issued graphics:

• A symbol indicating that the package contains THC.
• A symbol indicating that the package is not legal or safe for people younger than 21.

Each symbol must:

• Be unobscured.
• Measure at least one-half inch by one-half inch.
• Use the Department-issued format.
• Be used only for its prescribed purpose.

The symbols should not be redrawn, modified, incorporated into a logo, or used as decorative graphics. Label dimensions should be established early enough to accommodate both symbols without overlapping other required information.

Chemotype Information

The label must display the applicable chemotype:

• “High THC, Low CBD”
• “Moderate THC, Moderate CBD”
• “Low THC, High CBD”

The applicable category is determined using the product’s THC-to-CBD ratio and total THC percentage.

A product that does not fit precisely within one category must use the chemotype that most closely fits, based on a mathematical analysis of its THC-to-CBD ratio. The chemotype should therefore be assigned based on verified product data rather than on marketing language or anticipated product effects.

High-Potency Concentrate Warning

A cannabis concentrate with a total THC concentration greater than 30% must display the following warning:

“This is a high-potency cannabis product and may increase the risk of psychosis.”

Connecticut permits the warning to appear voluntarily on cannabis with a total THC concentration at or below 30%.

The label team should distinguish this package-level warning requirement from the separate high-THC notices that retailers may need to display on menus, advertisements, signage, or within designated retail areas.

Extended-Content Labels, Inserts, and Static QR Codes

Connecticut allows specified information to be provided through:

• An extended-content label.
• A package insert.
• A static QR code.

This information must also be available in the retail establishment and on the website of the cannabis establishment that sells the product.

The required extended information includes:

• The types of cannabis incorporated into the product.
• The processing techniques and solvents used to produce and manufacture it.
• Every inactive ingredient comprising at least 1% of the cannabis.
• The harvest date for raw cannabis and products containing raw cannabis.
• The date of final packaging for sale to consumers.
• The complete cannabinoid and terpene profile.
• Applicable additives and excipients.
• The required quantities in metric units and as percentages.
• A statement concerning testing for microbiological contaminants, mycotoxins, heavy metals, pesticide residue, and residual solvents.
• The testing date and whether the result was satisfactory or failing.
• Information identifying the establishments responsible for cultivation, propagation, harvesting, and manufacturing.
• The legal entity name, business address, email address, and telephone number of each applicable establishment.
• All four of Connecticut’s additional warning statements.
• The prescribed statement concerning cannabis, yeast and mold, testing, and possible decontamination or remediation.
• Any additional product-specific warning required by the Commissioner.

A static QR code does not replace the unique identifier, registered product name, expiration date, quantity, serving information, directions, primary warning, rotating warning, chemotype, or required symbols that must remain on the physical package label.

The QR destination should be reviewed as part of the label approval process. Businesses should confirm that:

• The code remains functional and readable.
• The destination presents the required information without additional navigation.
• The information matches the product and package.
• The content remains available for the product’s expected market life.
• Changes to laboratory results, ingredients, dates, warnings, or responsible establishments are reflected accurately.
• The destination does not introduce prohibited or misleading promotional content.

Labels for Internal Packaging

When separate internal packaging is used to satisfy the applicable packaging-performance requirements, the internal package remains subject to Connecticut’s labeling rules.

Certain information may be omitted from the internal label under the applicable exception, but the internal label must still provide the required identifying and safety information and must include total THC and total CBD content. The external package must include all information required for the consumer package.

The internal and external labels should be developed together. The information on both layers must be consistent with the product, laboratory results, registered information, and Cannabis Analytic Tracking System records.

Delivery Device Cartridge Labels

A delivery device cartridge containing cannabis must carry a separate, clearly legible label. The type must be flat, regular, Times New Roman, and as large as the cartridge reasonably allows.

The cartridge label must identify:

• The cannabis establishment where the cannabis was grown or manufactured.
• The cannabis brand.
• The total THC content.
• The total CBD content.
• The expiration date.
• The unique identifier.

A delivery device cartridge may include the embossed, debossed, or similarly printed name of the cannabis establishment and a qualifying logo containing no more than three colors. Other printing, graphics, embossing, debossing, or hidden features are prohibited unless expressly required or permitted.

Additional Medical Marijuana Labeling

Cannabis sold to a qualifying patient or caregiver requires additional information beyond the general label requirements. Depending on the transaction and product, this may include:

• The dispensing date.
• Patient and caregiver information.
• The certifying practitioner.
• The dispensing establishment and licensed pharmacy employee.
• The serial number associated with the dispensation.
• Alcohol content when applicable.
• Updated information when a product has been diluted.
• The Department-issued medical marijuana graphic.

A label developed solely for the adult-use market should not be used for a medical marijuana product without confirming and adding the applicable medical information.

Review Section 21a-421j-32 of Connecticut’s current Regulation of Adult Use Cannabis policies and procedures and the labeling provisions in Chapter 420h before approving a core label, extended-content panel, insert, QR code, internal label, or delivery device cartridge label.

Product-Specific Packaging, Serving, and Potency Requirements

Connecticut’s requirements depend on the form of cannabis, serving configuration, intended use, potency, and market.

Before selecting a package, businesses should determine:

• Whether the cannabis will be sold in the adult-use or medical market.
• Whether the product is raw cannabis, a pre-roll, edible, beverage, concentrate, vape oil, tincture, topical, or another permitted form.
• Whether the package contains one or multiple servings.
• The total THC concentration and quantity.
• Whether individual servings must be demarcated and separable.
• Whether the product requires special markings, warnings, or cartridge labeling.
• Whether the package supports the applicable stability and shelf-life requirements.
• Whether the specific package type and size have been included in stability testing.

Adult-use cannabis permitted for sale generally must be homogeneous and remain shelf-stable for at least 60 days after opening without refrigeration. Package selection should therefore account for the complete product, closure, barrier, storage, and stability system.

Cannabis Flower and Pre-Rolls

An adult-use package cannot contain more than one ounce of cannabis or its equivalent.

The current adult-use sale limit for cannabis flower and other cannabis plant material is 35% total THC on a dry-weight basis. Products between 30% and 35% total THC that were previously registered for medical use may be updated for the adult-use market when the Department’s registration and label-modification procedures are followed.

Retailers must treat certain high-THC products differently from other cannabis. Flower or other plant material containing more than 30% total THC must be displayed in the form and area prescribed by the Department. Retail menus and advertisements must also include the applicable high-THC notice.

These requirements should not be confused with the package quantity limit or the separate warning requirement for concentrates.

Raw cannabis, including loose flower and pre-rolls, constitutes one product category for stability-testing purposes. A change to the specific type or size of final packaging requires stability testing in the new package.

A pre-roll intended for combustion may display a cannabis-establishment logo on its wrapping. The wrapping and the substance used to create the logo are treated as ingredients and are subject to the applicable testing requirements. A filter that is not intended for combustion may also carry a cannabis-establishment logo.

The pre-roll, filter, wrapper, container, closure, label, and any printed or applied substances should be evaluated together.

Edible Cannabis Products

A standardized serving of adult-use edible cannabis cannot contain more than 5 milligrams of total THC. A multi-serving edible package cannot contain more than 100 milligrams of total THC.

Each serving in a multi-serving package must be physically demarcated and readily separable so a reasonable person can determine:

• What portion constitutes one standardized serving.
• The maximum possible total THC in the entire package.

If demarcating and separating the servings is impracticable, the entire package generally cannot contain more than 5 milligrams of total THC.

A package intended for multiple servings must also be resealable, continuously child-resistant, and capable of preserving the integrity of its contents.

Edible products that can maintain a defined external form must generally:

• Use a cuboid or spherical form unless the Commissioner approves another form.
• Be conspicuously marked with the capital letters “THC” in a plain font.
• Make each THC marking at least 25% of the product’s largest side.
• Avoid unauthorized printing, graphics, embossing, debossing, or hidden features.

A mint must be cuboid in shape. The product itself cannot resemble a commercial product that does not contain cannabis or use a design, mold, or form associated with or likely to encourage use by people younger than 21.

Adult-use cannabis also cannot be offered as a capsule, pill, tablet, sublingual, suppository, or another product administered through a bodily orifice or membrane other than orally. Different product forms may remain available within the medical marijuana program under its separate requirements.

Edible product development must coordinate:

• Serving size and total package potency.
• Physical demarcation and separability.
• Product shape and THC markings.
• Ingredient and allergen information.
• Package color and label restrictions.
• Child resistance and resealability.
• Tamper evidence and light resistance.
• Food-contact and contamination controls.
• Stability testing and expiration dating.

Cannabis Beverages

An adult-use cannabis beverage cannot contain more than one standardized serving. The 5-milligram THC limit therefore applies to the complete beverage container.

Cannabis beverages remain subject to the general child-resistant, tamper-evident, light-resistant, impervious, labeling, warning, and registration requirements.

A qualifying uncolored aluminum-alloy bottle or can may be used for cannabis liquid when it contains at least 8 fluid ounces and contains no added color from painting, dyeing, anodizing, or other methods. This exception concerns the container's appearance and does not remove any other requirements.

Every registered cannabis beverage requires stability testing using the specific type and size of final packaging. Changing the can, bottle, closure, liner, or package size may require the beverage to undergo stability testing again.

The beverage formulation, serving limit, fill volume, headspace, closure, liner, tamper-evident feature, child-resistant function, barrier performance, label, and final package should be developed as a single system.

Cannabis Concentrates and Vape Products

The current adult-use sale limit for a cannabis product other than flower or cannabis plant material is generally 70% total THC on a dry-weight basis. Prefilled cartridges used in an electronic cannabis delivery system are excluded from this potency ceiling.

The Department has established procedures for updating products with 60%-70% total THC that were previously registered for medical use, so they may be treated as dual-market products when all applicable requirements are met.

Several separate thresholds may apply:

• A concentrate containing more than 30% total THC requires the package-level high-potency warning.
• Certain products containing more than 60% total THC must be displayed separately and identified with the applicable high-THC notice on retail menus and advertisements.
• The general adult-use sale ceiling for applicable non-flower products is 70% total THC.
• Prefilled electronic-delivery-system cartridges are excluded from the 70% ceiling but remain subject to testing, packaging, labeling, and registration requirements.

The concentration of a product should therefore be reviewed against every applicable testing, warning, display, sale, and registration requirement rather than against a single potency threshold.

Vape oils constitute a separate product category for stability testing. The first batch of each registered vape oil must be tested in its final package, and a change to the type or size of final packaging requires new stability testing.

Packaging for a vape product should also account for:

• Compatibility between the formulation and cartridge materials.
• Potential leakage or clogging.
• Closure and seal integrity.
• The prohibition on specified ingredients that are harmful when inhaled.
• The required cartridge label.
• Total THC and total CBD content.
• The expiration date and unique identifier.

Tinctures, Oils, and Topical Products

Tinctures and oils other than cannabis beverages constitute one stability-testing category. Topical products constitute a separate category.

These products remain subject to the general package-performance, design, warning, labeling, potency, and registration requirements. The product’s intended use does not remove the need for child resistance, tamper evidence, light resistance, or protection against contamination.

Package development should account for:

• The route of administration.
• Product viscosity and dispensing method.
• The amount delivered per activation when applicable.
• Compatibility with droppers, pumps, sprayers, liners, seals, and closures.
• Ingredient and active-ingredient disclosures.
• Leakage and evaporation.
• Light and oxygen exposure.
• The expiration date supported by stability testing.

A container used for an ordinary cosmetic, food, supplement, or household product should not automatically be used for cannabis without confirming that the complete configuration satisfies Connecticut’s requirements.

Review the Department’s current notice concerning products containing 30% to 35% THC and 60% to 70% THC and the current adult-use cannabis policies and procedures when determining the requirements for a specific product.

Final-Package Testing and Product Registration

Connecticut connects product testing, final packaging, stability, labeling, and product registration.

Except when cannabis is being conveyed for laboratory testing, cannabis generally cannot be sold, transferred, transported, or otherwise conveyed to a consumer, qualifying patient, or caregiver unless:

• Its product name has been successfully registered with the Department.
• Its final packaging has undergone the required stability testing.

Stability Testing in Final Packaging

Stability testing must be performed using each specific type and size of final packaging covered by the applicable requirement.

Testing applies to:

• The first registered batch produced in end-user form within each established product category.
• The first batch of each registered cannabis beverage.
• The first batch of each registered edible cannabis product.
• The first batch of each registered vape oil.
• Each applicable medical marijuana batch identified by the policies.

Connecticut’s established product categories include:

• Raw cannabis, including loose flower and pre-rolls.
• Vape oils.
• Concentrates intended for inhalation.
• Tinctures and oils other than cannabis beverages.
• Topical products.

Stability testing is performed at 30-day and 60-day intervals using samples set aside before the registration application for the applicable batch. The required testing includes cannabinoid analysis as well as the applicable heavy-metal and microbial testing.

A change to the specific type or size of final packaging requires stability testing in the new package. For cannabis beverages and edible cannabis products, the testing requirement applies to the applicable registered brand and new final-package configuration.

Package changes that may trigger further review include:

• Switching container materials.
• Changing the container size or fill volume.
• Replacing the closure or liner.
• Adding or removing internal packaging.
• Changing a cartridge, dropper, pump, or dispensing component.
• Moving from a bottle to a pouch, jar, tube, can, or another format.
• Changing barrier, seal, or light-protection characteristics.

A change to a decoration or label may not always constitute a new type or size of final packaging, but it should still be evaluated for its effects on package performance, regulatory information, and the registered product.

Product Registration Information

The applicable producer, cultivator, micro-cultivator, product manufacturer, or food and beverage manufacturer must submit the required product-registration information to the Department.

The application must include:

• Cannabis laboratory testing and analysis results supported by a Certificate of Analysis issued no more than 30 days before the application is submitted.
• The required information concerning ingredients, processing techniques, and solvents.
• The proposed product name.

The finished product must continue to contain the same ingredients and use the same production method associated with the registered product name. Laboratory results must also verify that the cannabinoid, terpene, and applicable active-ingredient profiles remain within the required range.

A registered product name cannot be:

• Identical or confusingly similar to an existing non-cannabis product.
• Identical or confusingly similar to an unlawful product or substance.
• Identical or confusingly similar to a previously registered cannabis product name.
• Obscene or indecent.
• Associated with or likely to encourage use by people younger than the applicable age.
• Related to the product’s benefits, safety, or efficacy without the required supporting evidence or clinical data.

Product registration does not constitute approval of every aspect of the package or label. The cannabis establishment remains responsible for confirming compliance with all applicable laws, policies, procedures, and product-specific requirements.

Stability Results and Label Revisions

If a stability sample falls outside the permitted 90%-110% range, the cannabis establishment must notify the Department within 2 business days.

The establishment generally cannot continue manufacturing, packaging, selling, transferring, transporting, or otherwise conveying the affected product category or applicable beverage or edible brand until:

• The label information has been revised to accurately reflect the product’s composition.
• The expiration date has been corrected when necessary.
• The Department has approved the applicable revisions.

Laboratory results and Certificates of Analysis also have limited validity. The applicable results remain valid until the earlier of:

• One year from the date of the Certificate of Analysis.
• The product’s expiration date.

After that point, the cannabis must be retested and produce satisfactory results before it may continue through the regulated distribution system.

Testing records, registered product information, packaging specifications, artwork, expiration dating, and Cannabis Analytic Tracking System data should therefore be maintained as connected records. A change to one element may require corresponding changes to several others.

Review Sections 21a-421j-29 and 21a-421j-30 of Connecticut’s current Regulation of Adult Use Cannabis policies and procedures before changing a formulation, product name, package type, package size, label, or expiration date.

Responsible Cannabis Packaging Materials in Connecticut

The Connecticut cannabis requirements reviewed for this guide do not prescribe a single packaging material or establish a universal recycled-content requirement for every cannabis package.

A cannabis business may consider post-consumer recycled plastic, reclaimed ocean-bound plastic, plant-based materials, recycled glass, metal, paperboard, or other responsible materials, provided the complete packaging system complies with applicable cannabis regulations.

Material selection does not override the requirements for:

• Child resistance.
• Tamper evidence.
• Light resistance and uniform opacity.
• Protection against contamination.
• A single uniform package color.
• White packaging and labels for edible cannabis products.
• Product and package compatibility.
• Final-package stability testing.
• Required labels, warnings, symbols, and traceability information.

A material should not be described as compliant without evaluating the complete container, closure, liner, seal, internal packaging, label, product, and filling process.

Connecticut Toxics-in-Packaging Requirements

Connecticut’s general toxics-in-packaging law applies separately from the cannabis requirements.

The law prohibits the intentional use of:

• Cadmium.
• Hexavalent chromium.
• Lead.
• Mercury.

The combined incidental concentration of these regulated metals must remain below 100 parts per million by weight.

Connecticut also restricts intentionally added PFAS in food packaging. The prohibition took effect January 1, 2024. Packaging and food-contact components used for edible cannabis products should be evaluated for compliance with this requirement.

Businesses should obtain appropriate material, ink, coating, liner, adhesive, and food-contact documentation from their suppliers. A child-resistant certificate does not establish compliance with Connecticut’s chemical or food-packaging restrictions.

Review the Connecticut Department of Energy and Environmental Protection’s information on Toxics in Packaging and PFAS in food packaging when evaluating package materials and components.

Recycled Content and Cannabis Beverage Containers

Connecticut has established post-consumer recycled-content requirements for qualifying plastic beverage containers.

Beginning January 1, 2027, covered plastic beverage containers must contain an average aggregate of at least 25% post-consumer recycled content. The minimum increases to 30% beginning January 1, 2032.

Whether a particular cannabis beverage container is covered depends on the statutory definitions and the product’s classification. Businesses selling cannabis beverages in plastic containers should confirm:

• Whether the container qualifies as a plastic beverage container under Connecticut law.
• Which entity is treated as the producer.
• Whether registration and annual reporting are required.
• How the aggregate recycled-content percentage is calculated.
• Whether an exemption or waiver applies.
• How the requirement interacts with the cannabis package-performance and stability rules.

Review Connecticut DEEP’s current Plastic Beverage Container Recycled Content Law guidance before selecting a plastic cannabis beverage container.

Evaluating Responsible Materials

When comparing material options, businesses should consider:

• The type and amount of material used.
• The percentage and source of recycled, reclaimed, or plant-based content.
• Product-contact and food-contact suitability.
• Child-resistant testing for the exact package configuration.
• Tamper-evident feature integration.
• Uniform opacity and light protection.
• Barrier and seal performance.
• Compatibility with the cannabis formulation.
• Whether inks, coatings, liners, adhesives, or decorations contain restricted substances.
• The number of separate packaging components.
• The effects of labels, closures, liners, and seals on the intended recovery pathway.
• The collection and recovery systems available where the product will be sold.
• The evidence supporting environmental claims.

A responsible material does not automatically produce a responsible package. An unnecessarily large package, an incompatible material combination, a nonrecoverable decoration, or an avoidable secondary component can affect the package’s overall material use and end-of-life options.

At the same time, reducing material cannot come at the expense of required performance. Removing a liner, seal, internal package, or outer component may affect child resistance, tamper evidence, contamination protection, light resistance, stability, or label space.

Environmental Packaging Claims

Terms such as recyclable, recycled, reclaimed, plant-based, biodegradable, compostable, reusable, refillable, and plastic-free describe different attributes. They should not be used interchangeably.

Environmental claims may be communicated through words, symbols, certifications, imagery, or the overall presentation of a package. Claims should be accurate, specific, and supported by appropriate evidence.

For example:

• A recycled-content claim should identify the applicable percentage and component.
• A recyclable claim should account for the availability of appropriate collection and recycling systems.
• A compostable claim should be supported by appropriate testing and should distinguish industrial from home composting.
• A plant-based claim should identify the material and should not imply that the package is automatically biodegradable or compostable.
• A reusable or refillable claim should reflect a realistic system that allows the package to be reused or refilled safely.

The Federal Trade Commission’s Green Guides provide guidance on recycled content, recyclability, compostability, renewable materials, refillability, source reduction, certifications, and other environmental marketing claims.

Manufacturing origin also does not determine compliance or environmental performance. Domestic production may affect transportation, lead times, traceability, inventory availability, and supply chain strategy, but it does not, by itself, establish that a package complies with Connecticut law or has a lower environmental impact.

Choosing Cannabis Packaging for the Connecticut Market

Start with the product and regulatory pathway rather than the container. The appropriate package depends on the product’s form, potency, serving configuration, intended use, market, formulation, and stability requirements.

Before selecting a package, establish:

• Whether the product will be sold in the adult-use market, medical market, or both.
• Whether it is raw cannabis, a pre-roll, edible, beverage, concentrate, vape oil, tincture, topical, or another permitted form.
• The amount of cannabis or dried-cannabis equivalent in the package.
• The total THC concentration and quantity.
• The amount of THC per serving or unit.
• Whether the package contains one or multiple servings.
• Whether edible servings must be physically demarcated and separable.
• Whether the package must be resealable and continuously child-resistant.
• Whether the exact container-and-closure configuration has appropriate child-resistant documentation.
• How tamper evidence will be incorporated.
• Whether the entire package is uniformly opaque and light-resistant.
• Whether the packaging is impervious and protects the product against contamination.
• Whether the package and label satisfy the applicable color restrictions.
• Whether the product and packaging avoid resemblance to non-cannabis or youth-oriented goods.
• Whether the materials comply with Connecticut’s toxics-in-packaging requirements.
• Whether food-contact and PFAS requirements apply.
• Whether recycled-content registration, reporting, or minimums may apply to a beverage container.
• Whether the package provides enough space for the required label, warnings, symbols, serving information, and cannabinoids.
• Whether an extended-content label, insert, or static QR code will be used.
• Whether separate internal packaging is necessary.
• Whether the specific type and size of final packaging have undergone the required stability testing.
• Whether changing the package will require new testing or an updated product registration.

The package should then be evaluated using the intended product and filling process.

Comparing Cannabis Packaging Suppliers

When comparing suppliers and packaging options, businesses should request and review:

• Product specifications and technical drawings.
• Child-resistant testing and supporting documentation.
• Material and food-contact documentation.
• Information concerning restricted substances.
• Samples for filled-package and application testing.
• Closure application and sealing requirements.
• Tamper-evident options.
• Label dimensions and application tolerances.
• Compatibility with manual or automated filling equipment.
• Minimum order quantities.
• Customization and production lead times.
• In-stock availability and reorder planning.
• Quality-control and traceability information.
• Evidence supporting environmental and performance claims.

A package supplier can provide specifications, samples, test documentation, and information on available materials and customization options. The cannabis establishment remains responsible for confirming that the complete product, packaging, label, testing, registration, and distribution system complies with current Connecticut requirements.

Frequently Asked Questions About Connecticut Cannabis Packaging

What are the primary cannabis packaging requirements in Connecticut?

Under Connecticut’s current adult-use cannabis policies, consumer packaging must generally be:

• Child-resistant under the federal special-packaging standard identified in 16 CFR 1700.1(b)(4).
• Tamper-evident.
• Entirely and uniformly opaque and light-resistant.
• Impervious and capable of protecting the cannabis from contamination.
• Entirely and uniformly one color.
• Properly labeled with the required product, cannabinoid, warning, symbol, serving, and traceability information.

The package must also comply with the requirements applying to the product’s form, potency, serving configuration, intended market, and final-package stability testing.

Does Connecticut require cannabis packaging to be child-resistant and tamper-evident?

Yes. Child resistance and tamper evidence are separate requirements.

A child-resistant package must satisfy the applicable federal special-packaging standard. A tamper-evident package must have one or more indicators or barriers that make a breach apparent to a reasonable person.

A package intended for multiple servings must also be resealable, continuously child-resistant, and capable of preserving the integrity of its contents.

Can cannabis packaging be transparent in Connecticut?

Connecticut defines light-resistant packaging as packaging that is entirely and uniformly opaque and protects all of its contents from light.

A transparent container should not be assumed to comply merely because it carries an opaque label. The complete package configuration must provide the required light protection while satisfying the applicable child-resistant, tamper-evident, contamination, color, and labeling requirements.

Does edible cannabis packaging have to be white in Connecticut?

Packaging for an edible cannabis product must generally be entirely and uniformly white. Labels on edible cannabis products, including cannabis beverages, must also generally be entirely and uniformly white.

Connecticut provides a limited-appearance exception for certain cannabis liquids packaged in qualifying uncolored aluminum-alloy bottles or cans that contain at least 8 fluid ounces. The exception does not remove the other packaging, serving, testing, or labeling requirements.

How much THC may an adult-use cannabis product contain in Connecticut?

Several different limits and thresholds may apply:

• A standardized edible serving cannot contain more than 5 milligrams of total THC.
• A multi-serving edible package cannot contain more than 100 milligrams of total THC.
• A cannabis beverage cannot contain more than one standardized serving, so the complete beverage container is generally limited to 5 milligrams of total THC.
• Cannabis flower and other cannabis plant material offered for adult-use sale are generally limited to 35% total THC on a dry-weight basis.
• Adult-use cannabis products other than flower or plant material are generally limited to 70% total THC on a dry-weight basis, with an exclusion for qualifying prefilled electronic-cannabis-delivery-system cartridges.

Separate warning, display, menu, advertisement, testing, and registration requirements may apply at lower THC thresholds.

What information must appear on a Connecticut cannabis label?

Depending on the product, the primary package label must generally provide:

• The Cannabis Analytic Tracking System unique identifier.
• The product name registered with the Department.
• The responsible cultivator or manufacturer.
• The expiration date.
• Net weight or volume.
• Serving information when applicable.
• Directions for use and storage.
• The typical onset-time range.
• Active ingredients and cannabinoid quantities.
• Allergen information.
• The applicable chemotype.
• Required warnings.
• The Department-issued THC and age symbols.

Additional information may be required for edibles, concentrates, delivery device cartridges, internal packaging, and cannabis sold to qualifying patients or caregivers.

Can a QR code replace the required Connecticut cannabis label?

No. A static QR code, extended-content label, or package insert may be used for specified additional information, but it cannot replace the information Connecticut requires on the primary physical package label.

The extended information must also be available at the retail establishment and on the website of the cannabis establishment selling the product.

Does changing a cannabis package require new stability testing?

A change to the specific type or size of final packaging requires stability testing using the new package.

Changes to the container material, size, fill volume, closure, liner, internal packaging, cartridge, dispensing component, barrier properties, or light protection should therefore be evaluated before implementation.

Even when a change does not constitute a new package type or size, it may affect child-resistant documentation, tamper evidence, product compatibility, label information, expiration dating, or the registered product.

Does Connecticut approve individual cannabis packages or labels?

A cannabis product name must be successfully registered before the product is sold or transferred through the regulated market. The applicable final packaging must also undergo the required stability testing.

Product registration is not comprehensive approval of the package or label. Connecticut’s Medical Marijuana and Adult-Use Cannabis Product Registry states that registration indicates approval of the product name and is not a representation of legal compliance.

The cannabis establishment remains responsible for confirming that the complete product, package, label, testing, registration, and distribution system satisfies all applicable requirements.

Does Connecticut require recycled or sustainable cannabis packaging?

The cannabis requirements reviewed for this guide do not establish a universal recycled-content requirement or prescribe one packaging material for every cannabis product.

Separate Connecticut laws regulate toxic metals and intentionally added PFAS in certain packaging. Qualifying plastic beverage containers are also subject to registration, reporting, and post-consumer recycled-content requirements, including a 25% minimum beginning January 1, 2027.

Environmental claims should be accurate, specific, and supported by appropriate evidence. Recyclable, recycled, reclaimed, plant-based, compostable, biodegradable, reusable, refillable, and plastic-free describe different attributes and should not be used interchangeably.
