Is THCA Legal in New Hampshire?
Legal now — banned January 1, 2027. The controlling authority is Current federal delta-9 standard; SB 624 signed July 2, 2026 (Chapter 275), and the measurement standard New Hampshire applies is delta-9 today, total THC from January 1, 2027.
That standard decides everything. Where a state measures total THC, delta-9 plus 87.7% of the THCA content, high-THCA material fails on the same lab result that passes federally. Run any Certificate of Analysis through the total THC calculator to see both numbers.
What Happened in New Hampshire
SB 624 adds total THC expressly including THCA, plus a 0.4 mg per-container cap and 21+ restrictions, effective January 1, 2027. The federal change lands six weeks earlier on November 12, 2026.
