Is Delta-10 THC Legal in Massachusetts?

Last reviewed: May 21, 2026

No. Delta-10 THC is prohibited at hemp retail in Massachusetts. The Massachusetts Department of Agricultural Resources issued a Policy Statement on the Sale of Hemp-Derived Products on December 12, 2022 that treats commercially produced delta-10 and other synthetic-conversion cannabinoids as synthetically derived tetrahydrocannabinols outside the federal hemp exemption and outside the state hemp program under MGL Ch. 128 §§116-123. Intoxicating cannabinoid products may only be sold by Cannabis Control Commission-licensed marijuana retailers under MGL Ch. 94G and 935 CMR 500.00.

Massachusetts Cannabis and Hemp Overview

Massachusetts legalized adult-use cannabis through Question 4 in 2016, codified at MGL Ch. 94G. The Cannabis Control Commission regulates licensed adult-use and medical sales under 935 CMR 500.00. The hemp program at the Massachusetts Department of Agricultural Resources runs under MGL Ch. 128 §§116-123 and has used its statutory authority to prohibit intoxicating hemp derivatives.

Delta-10 THC is an isomer of delta-9 produced almost exclusively through chemical conversion from hemp-derived CBD. Massachusetts and federal regulators treat that production pathway as synthetic, which places delta-10 outside the hemp carve-out. For comparison with how Massachusetts treats delta-8, see our Massachusetts delta-8 page.

What Massachusetts Law Actually Says About Delta-10

MGL Ch. 128 §117 authorizes MDAR to determine reasonable commercial uses for hemp. The MDAR Policy Statement on the Sale of Hemp-Derived Products dated December 12, 2022 applies that authority to synthetically derived intoxicating cannabinoids including delta-10. The policy adopts the federal position that the 2018 Farm Bill did not change the controlled-substance status of synthetically derived tetrahydrocannabinols. Intoxicating cannabinoid products are marijuana under MGL Ch. 94G §1 and fall under 935 CMR 500.00.

How Enforcement Has Played Out

MDAR removed synthetic-conversion cannabinoids from the licensed hemp processor channel after the 2022 policy. In May 2024, MDAR, the Cannabis Control Commission, the Department of Public Health, and the Alcoholic Beverages Control Commission issued joint guidance reaffirming that intoxicating hemp products may not be sold at hemp retail, liquor stores, restaurants, or convenience stores. The ABCC warned licensees of suspension or revocation. Local boards of health handle most storefront enforcement, which produces uneven coverage across municipalities. The Attorney General has supported municipal cease-and-desist letters.

What This Means for Retailers Selling Delta-10 in Massachusetts

• Do not stock delta-10 products outside a Cannabis Control Commission marijuana retailer license. The MDAR 2022 policy treats synthetic-conversion cannabinoids as outside the hemp program.
• Liquor license holders should treat ABCC guidance as binding. Selling intoxicating hemp products on a licensed premises risks license suspension or revocation.
• CCC-licensed retailers can only sell products produced by licensed cultivators and processors. Synthetic-conversion delta-10 from out-of-state hemp processors will not generally enter the regulated supply chain.
• Maintain certificates of analysis that document the cannabinoid origin and conversion process for any remaining inventory.
• Plan for federal H.R. 5371 §781, signed November 12, 2025, which excludes synthetic and chemically converted cannabinoids from the federal hemp definition effective November 12, 2026. The federal change reinforces the existing Massachusetts position.
• Pull packaging that resembles candy brands or appeals to minors. May 2024 joint guidance flagged this as a top enforcement priority.

What This Means for Consumers Buying Delta-10 in Massachusetts

Delta-10 is generally unavailable through licensed channels in Massachusetts because licensed cultivators produce delta-9 products. Hemp-derived delta-10 sold at smoke shops, gas stations, or shipped from out-of-state online retailers falls outside both the licensed cannabis system and the hemp program. Delta-10 produces effects similar to delta-9 and triggers a positive on standard drug tests because delta-10 metabolites overlap with delta-9 metabolites.

Pending Federal Change

H.R. 5371 §781, signed November 12, 2025, explicitly excludes synthetic and chemically converted cannabinoids from the federal hemp definition. Delta-10 sits squarely inside the excluded category because it is produced through chemical conversion from CBD or delta-9. The provision takes effect November 12, 2026 and reinforces the Massachusetts prohibition. For background see our 2018 Farm Bill hemp revision explainer.
