Was reading my "DMT, the spirit molecule" book and i found this paragraph, pretty interesting considering this is coming from a trained medical professional.
"In the case of psychedelics, the high abuse potential that lawmakers noted was not the compulsive, out-of-control use commonly seen with drugs like heroin and cocaine. Psychedelics don't cause craving or withdrawal. In fact, one of their hallmarks is that they produce almost no effects after three or four daily doses, and abruptly stopping them causes no withdrawal. Rather, it was their acute effects that were so profoundly disruptive and at times disabling. Because of those highly destabilizing effects, Congress decided psychedelics must be tightly regulated."
