Total THC

A calculated value representing the total potential Delta-9 THC in a hemp product after complete decarboxylation — accounting for both existing Delta-9 THC and the THC that THCA would become if fully heated. The formula is: Total THC = (THCA × 0.877) + Delta-9 THC. Some states use Total THC (rather than just Delta-9 THC) as the legal threshold for hemp compliance, which can make high-THCA flower non-compliant even with low raw Delta-9 levels.
