The DEA total-THC rule takes effect November 12, 2026.

Eight-week countdown for THCA flower, Delta-8, and hemp-derived Delta-9 operators.

The 2018 Farm Bill created the hemp loophole. The DEA's November 12, 2026 total-THC rule closes it. Multi-billion dollar hemp-derived THC operators (THCA flower, Delta-8/9 gummies, hemp-derived Delta-9 beverages) must transition to state-legal cannabis payment rails, reformulate to sub-0.3 percent total THC, or exit the US market. Clay Pay places files at acquirers who serve both hemp and cannabis regimes and helps plan the transition documentation before the deadline.
