THCA Legality Guide 2025: State-by-State Overview

Texas

• THCA is conditionally legal if derived from hemp and contains less than 0.3% Delta-9 THC at the point of sale.
• Smoking or vaping THCA converts it to THC, which can result in legal risk or positive drug tests.
• A 2025 bill (Senate Bill 3) banning THC products including hemp-derived THC remains vetoed as of mid-2025; the status may change pending upcoming legislative sessions.
• Hemp growers must be licensed, and products should have lab testing and Certificates of Analysis for compliance.
• Transporting THCA with COA is advised for legal protection.

California

• THCA is legal under California’s well-established cannabis market.
• California permits recreational and medical cannabis, including hemp-derived THCA products that meet THC regulations.
• Producers must follow state testing, labeling, and safety standards.
• Emergency regulations on hemp-derived products are in place, pending possible permanent adoption.

Florida

• THCA is legal, provided the product is hemp-derived and contains less than 0.3% Delta-9 THC.
• Florida adheres to the 2018 Farm Bill definition and state hemp laws.
• Consumers should buy from reputable sources to ensure compliance.
• There is no protection for recreational cannabis; public consumption has legal risks.
• Legislative pressure exists to potentially tighten THCA rules in the future.

New York

• THCA is legal if derived from hemp and contains no more than 0.3% total THC, per the 2018 Farm Bill.
• Recreational cannabis is fully legal in New York, and THCA products are subject to the same regulatory framework.
• Products must comply with THC content limits, labeling, and testing requirements.
• Ongoing regulatory updates may affect THCA’s status; consumers are advised to stay informed.
• Delta-8 THC is banned in the state.

Illinois

• Recreational cannabis is legal; however, the legality of THCA flower is complicated.
• State law includes “post-decarboxylation” THC limits, meaning THCA that converts to THC may be illegal as hemp product.
• Despite ambiguous legality, THCA flower is still sold.
• Consumers and businesses should obtain lab tests and Certificates of Analysis for compliance.
• Illinois regulates cannabis thoroughly, limiting possession and requiring compliance with the Cannabis Regulation and Tax Act.

Colorado

• THCA flower is not legal under Colorado’s “total THC” law for finished hemp products.
• Recreational and medical marijuana are legal, allowing THC products to be bought from licensed dispensaries.
• Colorado has strict regulation of intoxicating hemp products, including milligram THC limits per serving.
• Non-intoxicating hemp products with low THC are permitted, but THCA flower does not qualify.
• Consumers should purchase cannabis flower from licensed sources instead of THCA flower.

Additional Note

• States with total THC testing laws often include THCA when calculating THC content, which may make some products illegal even if they comply federally.
• Several states like Tennessee are moving to ban or heavily restrict THCA products in 2025.
• Buyers and businesses should always verify local laws, keep documentation (Certificates of Analysis), and use licensed channels to stay compliant.
• THCA legality is evolving rapidly; regular updates from state agencies and legal advisories are essential for accurate compliance.
