What Vermont law says about THCA

Vermont allows adults 21 and over to buy cannabis from retailers licensed by the Cannabis Control Board (CCB). For hemp, the CCB measures potency as total theoretical THC, calculated as delta-9 THC plus THCA multiplied by 0.877 under Rule 2.9.2. Its hemp guidance states plainly that THCA is THC, and rejects the argument that raw flower is hemp until the THCA is heated.²

Under Rule 2.17, any product that is not a registered cannabis product is presumptively prohibited if it contains more than 0.3% total THC by dry weight, or more than 1.5 mg THC per serving or 10 mg per package without a 20:1 CBD ratio. The CCB also says anyone buying and selling THC material above 0.3% without a cannabis establishment licence is violating state drug laws. High-THCA flower can therefore only reach consumers as a tested, registered cannabis product sold in a licensed store or dispensary.¹²

Act 178 of 2026 moved all hemp oversight to the CCB and ties Vermont’s hemp definition to the federally defined THC level, so the federal total THC definition due to take effect in late 2026 will flow into state law. Products excluded from the hemp definition by Board rule are treated as cannabis products.³⁴

Local rules

Retail cannabis stores operate only in towns that have opted in to allow them.

Pending changes to watch

Rules implementing Act 178 (hemp product registration and possible 21+ limits for THC-containing hemp products) were not located as of September 2026.

How the federal hemp change affects Vermont

Separate from Vermont law, the federal definition of hemp is changing. Under the federal hemp redefinition passed in the FY2026 appropriations law, from 11 December 2026 hemp is measured by total THC, which counts THCA as well as delta-9 THC, and finished products are capped at 0.4 mg of total THC per container. High-THCA flower sold as hemp today will not meet that definition, so from that date it is treated as marijuana under federal law, whatever state law says.

Bills to delay or repeal the change are in congressional committees, but none had advanced as of September 2026. Our explainer on the federal hemp THC limit covers the detail, and THCA vs delta-9 THC explains why heat turns THCA into delta-9.

Timeline of recent changes

• 18 June 2026: Act 178 (S.323) signed: hemp regulation unified under the CCB and hemp defined by the federal THC level.
• 21 October 2023: CCB rules took effect presuming products over 0.3% total THC or over per-serving and per-package caps to be prohibited hemp.

THCA in neighbouring states

Rules change at the state line. Here is how THCA is treated in the states bordering Vermont, as of September 2026:

• New York: Legal 21+ at licensed dispensaries
• New Hampshire: Legal until 1 Jan 2027 ban
• Massachusetts: Licensed marijuana stores only, 21+

Carrying products across state lines can break the law of the state you enter, and federal law also applies. Check the destination state’s rules first.

Delta-8 in Vermont

Delta-8 is treated differently: in Vermont it is Banned (CCB Rule 2.17) as of September 2026. Read our guide to Delta-8 law in Vermont, or compare the two compounds in THCA vs Delta-8.

Frequently asked questions

Is THCA flower legal in Vermont?

Only as regulated cannabis. The Cannabis Control Board counts THCA towards total THC, so high-THCA flower is a cannabis product rather than hemp. Adults 21 and over may buy cannabis flower from licensed retail stores, but THCA flower sold as hemp by unlicensed shops or websites is prohibited.

Can hemp or CBD shops in Vermont sell THCA flower?

No. Under CCB Rule 2.17 a product that is not a registered cannabis product is presumptively prohibited if it exceeds 0.3% total THC. The Board says buying or selling THC material above that level without a cannabis establishment licence violates Vermont drug laws.

Where can adults legally buy THCA flower in Vermont?

Adults 21 and over can buy cannabis flower, which is naturally high in THCA, from retail cannabis stores licensed by the Cannabis Control Board, and registered patients can use licensed medical dispensaries. Retail stores exist only in towns that have voted to allow them.
