Maryland Cannabis Packaging Regulations: A Complete Guide

Learn how Maryland cannabis packaging rules address child resistance, tamper evidence, opaque containers, labels, edibles, and responsible materials. This guide explains practical compliance checks by product type.

Maryland cannabis packaging requirements depend on the product, serving configuration, potency, intended market, and finished package format.

Under Maryland’s current regulations, cannabis products for retail sale must be individually packaged by a licensed grower or processor. The retail package must generally be child-resistant, tamper-evident, and opaque. Soft-sided packages must be at least 4 mils thick, rigid containers must have an appropriate tamper-evident feature, and packages containing multiple servings must be resealable.

Businesses should identify the product category and determine how the complete container, closure, liner, seal, label, and any measuring component will satisfy the applicable requirements before ordering packaging or approving artwork.

This guide addresses Maryland’s principal packaging and labeling rules, including package construction, warnings, product information, the Universal Symbol, access to Certificates of Analysis, edibles, liquids, tinctures, capsules, concentrates, vape products, topicals, medical cannabis, seeds, plants, and restrictions intended to protect minors.

Who Regulates Cannabis Packaging in Maryland?

The Maryland Cannabis Administration, commonly called the MCA, administers the state’s adult-use and medical cannabis programs.

The principal authorities include:

Amendments effective September 14, 2026, removed the “plain” packaging requirement, expanded restrictions on youth appeal, and added sublingual-pouch requirements. Retail packaging must still be opaque, child-resistant, and tamper-evident, with applicable construction and resealability requirements. Additional proposed amendments are separate from these effective changes. Check the current rulemaking status before approving artwork or production.

Maryland Cannabis Packaging Requirements at a Glance

Product or situation Principal packaging requirement
Retail cannabis products generally Each item must be individually packaged by a licensed grower or processor. The package must generally be child-resistant, tamper-evident, and opaque.
Soft-sided packages The package must be at least four mils thick and sealed so opening or tampering remains evident.
Rigid containers The container must use a tamper-evident seal, an adhesive band, or a seal on the lid or enclosure.
Multiple-serving packages The package must be resealable. Product-specific serving, potency, separation, and measuring requirements may also apply.
Edible cannabis products The general limit is 10 milligrams of THC per serving and 100 milligrams per package. Multiple servings must be physically separated as required.
Liquid edibles A container may hold only one serving and no more than 10 milligrams of THC.
Tinctures The container must have a resealing, child-resistant cap or closure and include a dropper measuring device.
Medical cannabis General packaging and labeling rules apply, with additional space, warnings, and patient-specific label information.
Seeds and plants for home cultivation These products are exempt from the general finished-product packaging rules but have separate package and label requirements.

These rules apply to the finished configuration. A jar, lid, pouch, tube, or seal should not be described as “Maryland compliant” without identifying the product, serving configuration, intended market, and complete package being evaluated.

Core Retail Packaging Requirements

Maryland treats child resistance and tamper evidence as separate protections. Child-resistant packaging is designed to be significantly difficult for a typical child younger than five to open, but not for a typical adult. Tamper evidence makes unauthorized access or alteration easily detectable.

Under the Alcoholic Beverages and Cannabis Article, section 36-203.1, a cannabis package distributed to a consumer or qualifying patient must conform to the child-resistant requirements in 16 C.F.R. section 1700.15(b)(1) and use tamper-evident packaging. COMAR 14.17.18.02 adds the current requirements for opacity, construction, and resealability.

A child-resistant closure does not necessarily show whether the package has been opened. A heat seal, tamper band, or adhesive seal does not make an otherwise unsuitable package child-resistant. The finished retail configuration must supply both functions.

Documentation for the Exact Configuration

Child-resistance documentation should cover the exact container or pouch, closure or zipper, dimensions, material, film structure, liner, assembly method, and single-use or multiple-use configuration. A certificate for one combination should not be assumed to cover another combination in terms of size, closure, component, supplier, or assembly.

For a multiple-serving product, confirm that the documentation addresses repeated opening and closing. A package is not continually child-resistant merely because its closure can be reattached.

Review any application instructions, torque requirements, sealing conditions, or quality-control procedures that affect performance. Production samples should match the tested configuration.

Soft-Sided and Rigid Packages

A soft-sided package must be at least four mils thick. Its opening must be sealed so that opening or tampering is evident, and the package must continue to show that it was previously opened.

A heat seal above a child-resistant zipper may provide a tamper-evident approach when supported by the package design and sealing process. Confirm the required seal width, temperature, dwell time, pressure, and inspection method with the supplier. Film thickness and a child-resistant zipper do not establish tamper evidence on their own.

A rigid container must have a tamper-evident seal or an adhesive band or seal on the lid or enclosure that indicates previous opening. Evaluate the container, closure, liner, induction seal, pressure-sensitive seal, tamper band, and label together. A feature should not obstruct required information or interfere with the child-resistant mechanism.

Opacity, Exit Packaging, and Resealability

The current rule requires retail cannabis packaging to be opaque. Evaluate opacity after the actual product is placed in the package and the container is closed, sealed, and viewed from every side. A clear window or translucent area may prevent the package from meeting the requirement.

Adding an opaque carton, sleeve, or exit bag does not automatically correct a transparent or otherwise unsuitable product package. Maryland defines exit packaging as an opaque bag, pouch, or other container used after a retail sale and before purchased items leave the licensed premises. The general rule nevertheless requires the retail cannabis-product packaging itself to meet the applicable child-resistance, tamper-evidence, and opacity requirements. Any design relying on another packaging layer should be confirmed with the MCA before production.

A package containing multiple servings must be resealable. Resealability is separate from child resistance, and product-specific rules may add requirements for serving separation or measuring devices.

Evaluate the complete package with the actual product, with expected filling, sealing, storage, transportation, and consumer-use conditions. Oils, terpenes, solvents, moisture, temperature, package curvature, and repeated opening can affect closure performance, seal integrity, opacity, and label adhesion.

Maryland Cannabis Labeling Requirements

Under COMAR 14.17.18.03, required information must generally be printed directly on the marketing layer or affixed to it as a label or sticker. Maryland defines the marketing layer as the outermost layer of a retail container that is predominantly visible.

Required text must be clearly written or printed in English and may be no smaller than size-six font or 1/12 inch. A label should remain legible and unobstructed after the package is filled, closed, sealed, and formed into its final retail presentation.

Required Warnings and Product Information

Every retail cannabis product must carry Maryland’s prescribed warnings addressing:

  • Lawful consumption by adults 21 or older or registered medical cannabis patients
  • Impairment while driving or operating machinery
  • Potential health risks, especially during pregnancy or breastfeeding
  • Keeping cannabis away from children and animals

A product intended for topical application requires an additional statement identifying that it is not intended for human consumption, ingestion, or inhalation. Every retail product must also display the Maryland Poison Center emergency telephone number, currently 1-800-222-1222.

Final artwork should reproduce the complete current warning language directly from the rule rather than using these summaries as label copy.

The general product information includes:

  • Net weight
  • Finished-product lot number
  • Name of the licensee that packaged the product
  • Name and telephone number of the manufacturing licensee for adverse-event reporting
  • An itemization, including weight, of the cannabinoids and terpenes specified for the product
  • A leading zero before the decimal point for a cannabinoid concentration below one percent
  • Applicable major allergens
  • All noncannabis ingredients
  • Solvents used to produce the product
  • Applicable harvest, packaging, production, expiration, or best-used-by dates

The state statute also requires the name, address, and telephone number of the dispensary that sold the product for adverse-event reporting. Because the statute and regulation identify different licensee contacts, businesses should plan space for both sets of information unless the MCA confirms how the requirements apply to the final label.

Verify variable information against the finished-product lot, production records, and test results before release. A fixed label template should reserve sufficient usable space for potency, terpenes, lot information, dates, and other data that may change between production runs.

Inner Label Layers, QR Codes, and Certificates of Analysis

Maryland permits specified information to appear on an inner label layer or through a link or QR code. Under the current regulation, this option applies to:

  • The itemization of cannabinoid and terpene ingredients
  • Major-allergen information
  • Noncannabis ingredients

The MCA’s packaging guidance also identifies nutrition facts as suitable for a peel-and-reveal label or QR code.

A Certificate of Analysis completed by an independent testing laboratory must be available on the package through a link or QR code. The MCA guidance states that the code should link directly to the individual Certificate of Analysis, not to a general website, product directory, or search page.

Warnings, disclaimers, and the Universal Symbol must remain directly on the outer marketing layer. A QR code, inner label, insert, or secondary webpage should not be used to relocate information that Maryland requires to remain visible on the physical package.

Test each digital destination before release. It should open without an account, identify the correct product and lot, work on common mobile devices, and remain available for the necessary retention period.

Maryland’s Universal Symbol and Label-Area Planning

Every retail cannabis package must display Maryland’s Universal Symbol on the front or in the most prominent area.

The symbol must:

  • Occupy an area of at least one-half inch by one-half inch
  • Remain in the form provided by the MCA
  • Not be modified, recreated, stylized, stretched, or distorted
  • Appear on a background that makes it clearly distinguishable and identifiable

Use the symbol shown or supplied by the MCA rather than tracing or recreating it. Confirm the finished printed dimensions, contrast, proportions, and visibility on a production-size package.

Reserve label space for the symbol, warnings, Poison Center number, product identity, net weight, lot information, licensee contacts, cannabinoids, terpenes, ingredients, allergens, solvents, dates, serving information, product-specific statements, and the Certificate of Analysis link or QR code.

Also account for closure overlap, tamper bands, seals, seams, folds, gussets, curvature, and peel-back instructions. Whenever practical, inspect a production-size label on the actual filled, closed, and sealed package before approving artwork.

Choosing Maryland Cannabis Packaging by Product Type

Select the package after confirming the product category, serving configuration, potency, dimensions, fill quantity, intended market, and labeling needs. Test the complete container, closure, liner, seal, label, and any measuring component with the actual product under expected filling, storage, transportation, and use conditions.

Flower and Pre-Rolls

Maryland’s general child-resistance, tamper-evidence, opacity, and construction rules apply to flower and pre-roll packages. Under COMAR 14.17.13.11, a dispensary may package, repackage, wrap, or roll usable cannabis when it follows the applicable sanitation, packaging, and labeling requirements, but Maryland does not permit point-of-sale or deli-style sales of usable cannabis.

Potential formats include child-resistant pre-roll tubes, pre-roll multipacks, pop-top bottles, jars with compatible child-resistant lids, and flexible packages with documented child-resistant zippers and a suitable tamper-evident seal.

Confirm flower weight or pre-roll dimensions, headspace, product movement, closure operation, moisture and odor management, opacity, tamper evidence, and usable label area. When supported by the finished configuration, “odor-resistant” is more accurate than “smell-proof.” The Pre-Roll Packaging FAQ provides additional guidance on formats and compatibility.

Concentrates and Vape Products

A concentrate package should combine an appropriate child-resistant closure with opacity and a tamper-evident feature suitable for the rigid or soft-sided format. Under COMAR 14.17.13.10, Maryland restricts a cannabis concentrate containing more than one gram to qualifying patients and caregivers, and the product must carry the applicable medical label information.

For a concentrate jar, evaluate usable capacity, neck finish, lid compatibility, liner, seal, application torque, leakage, migration, terpene and oil compatibility, solvents, viscosity, filling temperature, transportation orientation, and label adhesion.

For a vape product, confirm the complete device or cartridge dimensions, mouthpiece, cap, orientation, insert or retention component, charging port, potential for leakage, and heat exposure. The packaging should hold the hardware securely without activating, damaging, or contaminating it. An outer package does not correct incompatible or leaking hardware.

Edibles, Liquid Edibles, Tinctures, and Capsules

Under COMAR 14.17.13.05, Maryland generally limits an edible cannabis product to 10 milligrams of THC per serving and 100 milligrams per package. Each serving in a multiple-serving edible must be physically separated. Scoring or marking an intact product does not satisfy the physical-separation requirement, and the product must be homogeneous so that each serving contains the same amount of THC.

Solid edibles may use only geometric shapes. A shape, design, or flavor may not be likely to appeal to minors, and the product may not resemble a commercially available food or beverage marketed to children. Evaluate the product itself together with its wrapper, insert, container, label, and outer presentation.

COMAR 14.17.18.05 requires the applicable general information plus:

  • THC, CBD, and other marketed cannabinoid content per serving and per package
  • The number of servings and recommended serving size
  • Nutrition facts
  • Active and inactive ingredients in descending order of predominance by weight
  • Maryland’s required delayed-effects warning

Nutrition facts may appear on an inner label layer or through a qualifying link or QR code. The required warning must remain on the outer marketing layer, and final artwork should reproduce the current language directly from the rule.

A multiple-serving edible package must be resealable and include a measuring device appropriate for the product’s form. Multiple individually wrapped single servings may be placed in a larger package when each serving is properly packaged, and the marketing layer contains no more than 100 milligrams of THC.

A liquid edible container may hold only one serving and no more than 10 milligrams of THC. Confirm the finished bottle, cap, liner, tamper-evident feature, fill volume, formula, and label together.

Under COMAR 14.17.13.06, a tincture container must use a resealing, child-resistant cap or closure and include a dropper measuring device within the package. Evaluate dropper fit, graduation accuracy, leakage, formula compatibility, repeated use, and label durability. Maryland restricts capsules and tinctures above the adult-use potency thresholds to qualifying patients and caregivers. A separate MCA-approved pathway may apply to certain higher-potency medical edibles.

The Edible Packaging collection provides potential starting points for compatible products. Package selection does not replace required MCA product review or approval.

Topicals and Other Infused Non-Edible Products

Topicals and other infused non-edible products remain subject to Maryland’s general retail packaging rules. A topical also requires the additional label statement discussed above.

Select the container and dispensing system for the formula, viscosity, intended application, and recommended amount per use. Evaluate leakage, clogging, residue, alcohol, oils, solvents, filling temperature, liner and seal compatibility, closure operation, and label adhesion. Explore Sana Packaging’s Topical Packaging collection for potential starting points.

Cannabis Seeds and Plants

Under COMAR 14.17.18.06, cannabis seeds and plants sold for home cultivation are exempt from Maryland’s general finished-product packaging and labeling provisions in COMAR 14.17.18.02 through .05, but separate requirements apply.

A seed package must keep the seeds dry, prevent germination within the package, and avoid imparting toxic or harmful substances. Its marketing layer must identify the cultivation facility and dispensary, state the net weight or seed count, and display Maryland’s prescribed home-cultivation and age-or-patient statement.

For a plant or seedling, use a stable container that protects the roots and supports safe handling and transportation. Confirm the required identifiers and consumer information before sale rather than applying the general retail-cannabis label by default.

MCA Product Review Before Commercial Sale

Maryland requires approval before an edible cannabis product is offered for sale. The submission includes a rendering or photograph of the product, label, and package, along with potency and dosing information, the recipe and production process, and support for stability and expiration dating.

The MCA’s packaging and labeling guidance also identifies review procedures for liquid products, tinctures, capsules, sublingual pouches, and certain exempt products. Confirm the current submission process, documentation, and review scope before commercial production.

The manufactured product, packaging, and labeling should match the configuration reviewed by the MCA. Changes to the formula, potency, serving format, container, closure, material, label, or artwork may require renewed review or supporting documentation.

Medical Cannabis Packaging

Maryland applies its general retail packaging and labeling requirements to medical cannabis unless a more specific rule provides otherwise. Under COMAR 14.17.18.04, a medical cannabis package must reserve space for the dispensary to attach a personalized patient label.

The medical package must also carry Maryland’s prescribed warning concerning possession, consumption, and transfer by anyone other than the qualifying patient. For a product authorized for both medical and adult-use sale, the dispensary may apply that warning at the point of sale, and it is not required on a package sold to an adult-use consumer. A high-potency product available only to qualifying patients must carry the medical requirements when it leaves the grower or processor.

The personalized patient label includes:

  • The qualifying patient, certifying provider, and dispensing licensee
  • The dispensing date and product name
  • The strength of the applicable cannabinoid and terpene compounds
  • The quantity dispensed
  • Directions for use and instructions for proper storage or handling

Under COMAR 14.17.13.05, Maryland may approve a high-potency edible containing more than the general adult-use limits, but it may not exceed 40 milligrams of THC per serving or 400 milligrams per package. These products require MCA approval, third-party cGMP certification and supporting documentation, medical labeling, and sale only to qualifying patients or registered caregivers.

Plan the medical label area before selecting the package. The personalized label, medical warning, general label information, tamper-evident feature, and closure must remain legible and functional together.

Sublingual Pouches

Under COMAR 14.17.18.08, the general packaging and labeling rules apply to sublingual pouches unless otherwise stated. The package must carry the warning “Pouches are not intended to be heated, burned, or swallowed.”

Each pouch must display the universal symbol. If marking the pouch is impractical, individually wrap it and place the symbol on the wrapper. MCA guidance includes these products in its manual-approval process.

Package and Label Design Restrictions

COMAR 14.17.18.07 sets the following restrictions. Packaging and labeling may not:

  • Appeal to minors or resemble trademarked or product-specific packaging for commercially available candy, snacks, baked goods, or beverages.
  • Use images of food, candy, baked goods, cereal, fruit, or beverages, or the words “candy” or “candies”.
  • Use child-oriented cartoons, animals, neon colors, celebrities, mascots, features, likenesses, or phrases.
  • Mislead a person about the package contents.
  • Suggest endorsement by a state or local government through a seal, flag, crest, coat of arms, or similar insignia.
  • Depict cannabis consumption, overconsumption, or intoxicating effects.
  • Use anthropomorphic or fantastical graphics, including human traits assigned to animals or objects, or extraordinary abilities assigned to people, plants, animals, or objects.
  • Use sensory effects appealing to minors, including texture, scent, or sound.
  • Make medical or therapeutic claims, or other false or misleading statements.

Packaging, labels, and marketing layers may not obscure required warnings or information. The complete product may not target or be designed to appeal to anyone younger than 21.

Review the name, logo, typography, colors, imagery, flavor description, container, wrapper, insert, and marketing layer as one presentation. Removing one prohibited image may not correct a design that still resembles a familiar consumer product, targets minors, or creates a misleading impression.

Responsible Materials and Compliance

Maryland’s rules focus on the performance and presentation of the finished package rather than granting compliance based on a material category. Recycled-content plastic, plant-based plastic, ocean-bound plastic, glass, aluminum, and paperboard components may be considered when the complete configuration satisfies the requirements for child resistance, tamper evidence, opacity, thickness, resealability, and labeling.

Material selection should follow product classification and package-function decisions. For example, clear glass may require an appropriate opaque solution under the current rule, whereas a paperboard carton does not automatically render an immediate container noncompliant.

Evaluate source material, additives, colorants, coatings, liners, adhesives, inks, and secondary components for the intended product and process. Request accurate specifications and available documentation from each supplier, and test production-equivalent samples for filling, sealing, storage, transportation, and repeated use.

Environmental claims should be specific, supportable, and limited to the actual package component. Recycled content, plant-based content, or material recovery does not mean that a package is recyclable, compostable, biodegradable, or accepted by every local program. Compliance and responsible material selection should be evaluated as related but separate decisions.

Maryland Cannabis Packaging Preproduction Checklist

Before approving a production run:

  • Confirm the product category, adult-use or medical market, potency, serving configuration, and required MCA review
  • Verify the current statutes, regulations, guidance, and rulemaking status
  • Match the package and closure to the child-resistance documentation for the exact configuration
  • Confirm the tamper-evident method, opacity, youth-appeal restrictions, and four-mil minimum for soft-sided packaging

Frequently Asked Questions

Does Maryland Require Child-Resistant and Tamper-Evident Cannabis Packaging?

Yes. A cannabis package distributed to a consumer or qualifying patient must satisfy the applicable child-resistance and tamper-evidence requirements. Each function must be evaluated in the finished retail configuration.

Does Maryland Require Opaque Cannabis Packaging?

Packaging must be opaque. The separate “plain” requirement was removed effective September 14, 2026, but restrictions on youth appeal, misleading presentation, and prohibited claims still apply.

What Are Maryland’s Edible THC Limits?

An adult-use edible may generally contain no more than 10 milligrams of THC per serving and 100 milligrams per package. A liquid edible is limited to one serving and 10 milligrams per container. Separately approved high-potency medical edibles may contain up to 40 milligrams per serving and 400 milligrams per package.

Does Maryland Require a Universal Symbol?

Yes. Every retail cannabis package must display Maryland’s Universal Symbol on the front or in the most prominent area of the marketing layer. It must occupy at least one-half inch by one-half inch and remain in the form provided by the MCA.

Can a QR Code Replace Required Label Information?

Only specified information may be moved to an inner label layer or qualifying digital destination. Warnings, disclaimers, and the Universal Symbol must remain on the outer layer of the marketing materials. The Certificate of Analysis code should link directly to the report for the individual product and lot.

Can Maryland Cannabis Packaging Use Responsible Materials?

Yes, provided the complete package satisfies all applicable requirements. Recycled-content plastic, plant-based plastic, ocean-bound plastic, glass, aluminum, or paperboard does not make an otherwise unsuitable configuration compliant.
