Massachusetts CBD Laws: Sales, Licensing, and Labeling Rules

Massachusetts CBD laws permit the sale of hemp-derived CBD products that contain no more than 0.3% delta-9 THC on a dry weight basis, but the state prohibits adding CBD to food, beverages, and dietary supplements, and imposes specific labeling, testing, and licensing rules on anyone who grows or processes hemp. The source of the CBD matters as much as the THC level, and a federal definition change arriving in November 2026 will tighten what qualifies as legal hemp.

What Counts as Legal CBD

Massachusetts defines hemp as any part of the cannabis plant with a delta-9 THC concentration that does not exceed 0.3% on a dry weight basis.¹ CBD products derived from hemp that stays within that threshold are legal to possess, buy, and sell under state law. The Massachusetts Department of Agricultural Resources (MDAR) runs the hemp program and licenses growers and processors.

CBD derived from marijuana, meaning cannabis above the 0.3% THC line, is a different animal entirely. It falls under the Cannabis Control Commission (CCC) and can only be sold through licensed dispensaries. Before you buy, sell, or stock a CBD product, you need to know which side of that line it comes from.

What You Can and Cannot Sell

The most common mistake retailers make is stocking CBD-infused food and drinks. Massachusetts prohibits manufacturing or selling food containing CBD or THC, and this tracks federal law rather than conflicts with it. The FDA has concluded that because CBD is an active ingredient in an approved drug, adding it to food or marketing it as a dietary supplement violates the Federal Food, Drug, and Cosmetic Act.² The Department of Public Health enforces that prohibition through 105 CMR 500.00 and 105 CMR 590.00.³

The ban reaches further than obvious edibles. Full-spectrum, broad-spectrum, and whole-plant hemp extracts contain CBD and other cannabinoids, and none of those can go into food products, regardless of what the label discloses.⁴ Products making therapeutic or medicinal claims are also prohibited, as are animal food or treats containing hemp-derived CBD.⁵

Hemp-derived CBD products that are not food, beverages, or dietary supplements can be sold legally. That covers topicals like creams and balms, tinctures, and oils intended for external use or sublingual consumption rather than as food additives. A few hemp food ingredients have a separate path: the FDA has recognized hulled hemp seeds, hemp seed protein, and hemp seed oil as generally recognized as safe, so those can go into food products. Cosmetics containing hemp or CBD are also permitted if they comply with FDA cosmetics rules and avoid drug claims.⁴

Do Retailers Need a License?

No. MDAR does not require a license for retail establishments to sell hemp-derived products.⁶ The absence of a licensing requirement is not the absence of obligations.

Verify the supply chain. Products sold by licensed marijuana establishments and medical marijuana treatment centers must come from an MDAR-licensed hemp producer or processor and cannot be sourced from anywhere else.⁵ General retailers should request certificates of analysis from suppliers showing THC content, cannabinoid profile, and contaminant results. A supplier who can’t produce those documents is a problem.

Local boards of health have authority to inspect retail locations, remove non-compliant products, and act on permits for violations. Avoiding the prohibited categories, especially CBD-infused food and drink, is the single biggest thing you can do to stay out of trouble.

Labeling and Testing Rules for Processors

MDAR’s hemp processor policy sets specific labeling requirements. Every container of finished hemp product must display the following in legible text no smaller than 1/16 inch:⁷

Manufacturer name, license number, and address
Cannabinoid profile and potency, including THC and CBD concentrations per serving and per container
Batch identification number
State of origin for the hemp or hemp extract used
The disclaimer: “This product derived from Hemp has not been tested, analyzed, or approved by the Massachusetts Department of Agricultural Resources or the FDA”
Full ingredients list
Allergen warnings where applicable

Labels cannot claim that the product prevents, treats, or cures any disease, or that it alters the structure or function of the human body, unless the FDA has specifically approved the claim.⁷ That restriction reaches the product’s name too. “Pain Relief CBD Oil” would violate the rule.

On testing, MDAR requires hemp processors to use an independent testing laboratory applying the same protocols the CCC uses for marijuana products. For every batch of hemp extract, representative samples must go in for potency and contaminant testing, and the certificates of analysis must reference the batch identification number and confirm total THC below 0.3% along with all contaminant limits met.⁷ Labs must hold ISO 17025:2017 accreditation and be financially independent from any marijuana licensee.

Advertising and Health Claims

Health claims are the fastest way to attract enforcement. The labeling rule against disease claims extends to all advertising and marketing. You cannot suggest a CBD product cures, treats, or prevents any medical condition unless the FDA has approved that specific claim, and no such approvals exist for over-the-counter CBD products.

Massachusetts also has a broad consumer protection statute prohibiting unfair or deceptive practices in trade or commerce, with the attorney general holding rulemaking authority and the statute interpreted in line with the FTC Act.⁸ Unsubstantiated wellness language like “reduces anxiety” or “promotes healing” can be treated as deceptive advertising. Safer ground: describe ingredients, cannabinoid content, intended use, and sourcing. Stick to what you can prove.

Licensing for Growers and Processors

Anyone who grows, harvests, or processes hemp in Massachusetts needs a license from MDAR. Three types are available, each with its own fees:⁹

Producer (grower): $100 application fee plus $300 license fee, $400 total
Processor: $100 application fee plus $300 license fee, $400 total
Dual producer/processor: $100 application fee plus $500 license fee, $600 total

Producer and dual-license applicants must submit an FBI Identity History Summary report for each individual applicant and key participant, dated within 60 days of the application. Processor-only applicants do not need the FBI report. All applicants must provide a map of each growing or processing site.⁹

Licenses must be renewed annually. The renewal window runs October 1 through December 1, and licenses expire December 31. Miss the December 1 deadline and MDAR may reject the renewal, forcing a new application during the next application period of December 1 through April 30. All hemp activities requiring a license must stop if the license lapses.¹⁰ Renewal fees match the initial fees.

Hemp licenses are not transferable. If applicant names or business names change, the license is no longer eligible for renewal and a new application is required. Changes to growing or processing locations do not require a new license.¹⁰

The November 2026 Federal Definition Change

In November 2025, Congress amended the federal definition of hemp to measure total THC concentration rather than only delta-9 THC. The new definition takes effect on November 12, 2026.¹¹

This matters for products currently on shelves that contain hemp-derived cannabinoids like delta-8 THC or other THC isomers not counted under the delta-9-only measurement. Once total THC is the standard, products that fell under 0.3% delta-9 but carry other forms of THC may exceed the new limit and lose their legal status as hemp. Retailers should audit inventory well before November 2026 and get written confirmation from suppliers that products will comply.

Massachusetts is already somewhat ahead. MDAR has stated that synthetically derived delta-8 THC products are not permitted under the state hemp program, and the state’s hemp definition already references both delta-9 THC and tetrahydrocannabinolic acid.¹ The federal shift will still raise the pressure on anything with measurable THC beyond delta-9.

Who Enforces, and What Happens

Enforcement comes from several directions. For food-related violations, local boards of health are the front line. Under state food safety regulations, inspectors can order corrections with specific deadlines, and failure to comply can bring suspension or revocation of a food establishment permit and a stop to operations. A board of health can also refuse to issue or renew a permit for an owner convicted of a food-related crime, who has endangered public health, or who has failed to comply with applicable regulations.¹²

For hemp program violations, MDAR has authority over licensed producers and processors. Products exceeding 0.3% THC fall outside the legal definition of hemp and may be treated as marijuana, which pulls in CCC and potentially criminal jurisdiction. Licensed operations that fail inspections, miss renewal deadlines, or violate processing policies can lose their license.

CBD and Workplace Drug Testing

Full-spectrum CBD products contain trace amounts of THC that can accumulate with regular use and trigger a positive drug test. Pure CBD isolate products should not cause a positive result, but product quality varies and mislabeling happens.

Massachusetts offers some protection in the medical marijuana context. In the 2017 case Barbuto v. Advantage Sales & Marketing, the state’s highest court ruled that an employee fired after a positive drug test for off-duty medical marijuana use could pursue a disability discrimination claim, and that an employer may need to consider an exception to its drug testing policy as a reasonable accommodation when a physician determines medical marijuana is the most effective treatment for a qualifying condition. The ruling applies to medical marijuana, not to over-the-counter hemp-derived CBD. If you use CBD and face workplace drug testing, THC-free isolate products and retained certificates of analysis are your practical protection.

Shipping CBD to Other States

Hemp-derived CBD is federally legal, but individual states have their own rules on product categories, THC thresholds, and permitted uses. A product that’s legal in Massachusetts may violate the rules in the destination state. Before shipping, verify legality where the package is going, confirm your carrier accepts CBD shipments, and put controls in place to block orders to restricted jurisdictions. The compliance burden falls on the seller.
