THCA in Texas

THCA Laws in Texas

Hemp-derived THCA is federally legal under the 2018 Farm Bill when sourced from hemp containing ≤0.3% Δ9-THC on a dry weight basis. Texas has enacted laws that treat THCA as a controlled substance, effectively banning it.

Texas operated under a hemp-friendly framework until 2025, when the legislature passed HB 28 banning consumable hemp products containing more than 1mg of total THC per package. The law has faced legal challenges and ongoing injunctions. As of mid-2025, enforcement remains in flux — retailers and consumers should monitor official DSHS guidance closely.

Buying tips: Look for vendors with COA documentation showing Δ9-THC well below 0.3% dry weight. Many vendors have suspended shipping to TX pending the litigation outcome.

Federal vs. State Law

The 2018 Agriculture Improvement Act (Farm Bill) legalized hemp and hemp-derived cannabinoids at the federal level. THCA — tetrahydrocannabinolic acid — is the non-psychoactive precursor to THC found in raw hemp. When heated, THCA converts to THC via decarboxylation.

However, states retain the right to regulate hemp products within their borders. Some states calculate "total THC" to include THCA (using the formula: Total THC = THCA × 0.877 + Δ9-THC), which can cause high-THCA flower to exceed the 0.3% limit even if Δ9-THC alone is compliant.

As of 2026, the legal landscape continues to shift. Several states have moved to restrict hemp-derived cannabinoids while others have clarified permissive frameworks. Always check the most current state statutes and regulatory guidance.
