What New York law says about THCA

New York’s Cannabis Law defines total THC as the percentage of THCA multiplied by 0.877, plus the percentage of THC.² Part 114 applies that measure to cannabinoid hemp products, which must contain no more than 0.3% total THC.¹ Flower that is high in THCA therefore exceeds the hemp limit even when its delta-9 THC reading alone is low, and it is treated as cannabis.

Hemp flower that does meet the limit can be sold by licensed cannabinoid hemp retailers, but only to buyers aged 21 or over. Retailers may not sell hemp products labelled or advertised for smoking, or in the form of a cigarette, cigar or pre-roll, and must verify age before selling flower, concentrates or any product with more than 0.5 mg total THC per serving.¹

New York legalised adult-use cannabis through the Marihuana Regulation and Taxation Act in 2021, so THCA-rich flower is legal when bought from an OCM-licensed dispensary by adults 21 and over. Selling it as hemp through a smoke shop is an unlicensed cannabis sale. OCM told state legislators in February 2026 that intoxicating hemp should be routed through the adult-use framework, where testing, labelling and age rules already apply.³

Pending changes to watch

OCM is monitoring federal guidance on total THC and says states will evaluate how to align their programmes; no state change had been adopted as of September 2026.

How the federal hemp change affects New York

Separate from New York 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

• December 2023: Amended Part 114 adopted, keeping the 0.3% total THC limit and 21+ rule for hemp flower and concentrates.
• November 2021: Part 114 cannabinoid hemp regulations adopted using a total THC standard that counts THCA.
• March 2021: Marihuana Regulation and Taxation Act enacted, legalising adult-use cannabis for adults 21 and over.

• Connecticut: Licensed cannabis retail 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 New York

Delta-8 is treated differently: in New York it is Banned in hemp products as of September 2026. Read our guide to Delta-8 law in New York, or compare the two compounds in THCA vs Delta-8.

Frequently asked questions

Is THCA flower legal in New York?

Only as regulated cannabis. New York counts THCA towards the 0.3% total THC limit for hemp, so most THCA flower is cannabis under state law. Adults 21 and over can buy it legally from OCM-licensed dispensaries, not from hemp shops or smoke shops.

Can I buy hemp flower in New York?

Yes, if it tests at or below 0.3% total THC and is sold by a licensed cannabinoid hemp retailer. Buyers must be 21 or over, and retailers cannot sell hemp flower as pre-rolls, label it for smoking or package it with rolling papers or pipes.

Is it legal for a New York smoke shop to sell THCA flower?

No. Flower above the total THC limit is cannabis, and only businesses licensed by the Office of Cannabis Management may sell cannabis to consumers. Selling THCA flower without a licence is an unlicensed cannabis sale and is subject to state enforcement.
