What does the label state - 40 mg of THC or 40 mg of hemp ? My understanding is that THC is THC no matter what source, all those distinctions of hemp derived vs MJ derived are just semantics to get around the federal laws prohibiting sales of MJ but allowing hemp under the 2018 Farm Bill.
AI Overview
While chemically identical, delta-9 THC derived from hemp is different from delta-9 THC from marijuana in its source concentration, extraction methods, and legal status
. The legal distinction is based on the 2018 Farm Bill, which defines hemp as cannabis with 0.3% THC or less by dry weight.
Chemical identity
On a molecular level, delta-9 THC from hemp and delta-9 THC from marijuana are the exact same compound. The psychoactive effects experienced by the user are produced by the THC molecule itself, not by its origin.
