No. Hexahydrocannabinol (HHC) 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 HHC 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 through Cannabis Control Commission-licensed marijuana establishments under MGL Ch. 94G and 935 CMR 500.00.
Massachusetts legalized adult-use cannabis through Question 4 in 2016, codified at MGL Ch. 94G. The Cannabis Control Commission regulates licensed 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.
HHC is hexahydrocannabinol, a hydrogenated form of THC produced almost exclusively through chemical conversion from hemp-derived CBD or delta-9 followed by hydrogenation. Massachusetts and federal regulators treat that pathway as synthetic, which places HHC outside the hemp carve-out. For comparison with how Massachusetts treats delta-8, see our Massachusetts delta-8 page.
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 HHC. 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.
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.
HHC is generally unavailable through licensed channels in Massachusetts because licensed cultivators produce delta-9 products. Hemp-derived HHC 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. HHC produces effects similar to delta-9 and triggers a positive on standard drug tests because HHC metabolites overlap with delta-9 metabolites.
H.R. 5371 §781, signed November 12, 2025, explicitly excludes synthetic and chemically converted cannabinoids from the federal hemp definition. HHC sits squarely inside the excluded category because it is produced by hydrogenation of 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.

HHC is hexahydrocannabinol, a hydrogenated form of THC produced through chemical conversion from hemp-derived CBD or delta-9 followed by hydrogenation. The conversion process places HHC in the synthetically derived category.
Can I buy HHC at a Massachusetts dispensary?
Generally no. Cannabis Control Commission-licensed marijuana retailers carry delta-9 products from licensed cultivators, not synthetic-conversion HHC.
Does HHC show up on a drug test?
HHC metabolites overlap with delta-9 metabolites on standard tests and typically trigger a positive.
Can I order HHC online to Massachusetts?
Out-of-state online shipments to Massachusetts addresses fall outside the licensed channel and remain subject to enforcement.
What changes November 12, 2026?
