Cannabis laws can get confusing, especially when it comes to specific cannabinoids like THCA. The key thing to understand about THCA is that it’s non-psychoactive until it’s heated and turned into THC, the compound responsible for getting you high. So, how does that affect its legality in your state? Let’s dive into what each state says about THCA legality.

---

Alabama

Legal
THCA flower is legal here as long as the delta-9 THC content is below 0.3%. Alabama has embraced hemp and doesn’t heavily test finished hemp products for total THC content.

Alaska

Legal
Alaska legalized recreational marijuana years ago, so THCA and its products are completely fine to use and purchase.

Arizona

Legal
Arizona allows THCA for adults since legalizing recreational marijuana in 2020. You’re good to go whether it’s hemp or marijuana-derived.

Arkansas

Legal
THCA from hemp with less than 0.3% THC is perfectly legal here. However, be cautious about THC content as products with more than 0.3% THC are tightly regulated.

California

Gray Area
As of late 2024, California passed emergency regulations banning consumable hemp products with THC. THCA products fall into a tricky category, so it's best to double-check before purchasing.

Georgia

Illegal
Georgia has recently tightened its regulations on hemp-derived products, including THCA. In 2024, a bill (Senate Bill 494) was signed into law by Georgia's governor, which effectively closed a legal loophole for THCA. The bill redefined delta-9 THC to include its precursors like THCA, meaning that products containing THCA that could convert into THC when heated are now subject to stricter regulation. This change restricts the sale of hemp-derived products, including those containing THCA, to individuals over 21, and limits the way THCA products are sold and distributed within the state.
