Is THCA Legal in Maine?
Maine follows the federal delta-9 standard. The controlling authority is 7 M.R.S. § 2231 and PL 2025 c. 416 (LD 1920), and the measurement standard Maine applies is delta-9 only, with no total-THC conversion.
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 Maine
LD 1920 created a ‘potentially intoxicating hemp product’ category with 21+ sales and child-resistant packaging, but its enumerated cannabinoid list does not name THCA and it imposes no conversion rule.
