Pharmacopoeia because of continuing concerns about its safety. Degenhardt L, Hall WD. Previous studies exposing animals to tetrahydrocannabinol THC -- the main psychoactive component of marijuana -- show that repeated exposure to the drug causes structural changes in brain regions involved with these functions.
