In Detail
Delta-9-THC is the standard form of THC and the most extensively researched cannabinoid. The "Delta-9" refers to the position of a double bond on the ninth carbon in its molecular chain. This specific structure is what gives it a strong affinity for CB1 receptors in the central nervous system. Delta-9-THC is produced in the cannabis plant as THCA (tetrahydrocannabinolic acid), which is non-psychoactive. Heat through smoking, vaping, or cooking converts THCA into active Delta-9-THC through a process called decarboxylation. Typical cannabis flower contains 15-25% Delta-9-THC, though some high-potency strains exceed 30%.
Legal Status
The legal status varies widely. Legal for medical or recreational use in many US states. Federally Schedule I in the US. Legal in Canada, Uruguay, and parts of Europe for medical or recreational use.
