It's sad that the government places such arbitrary restrictions on what is and isn't legal for consenting adults to consume. Stuff like alcohol and tobacco is seen as a no brainier for legality. Meanwhile when the data clearly shows that many other substances are not only less harmful but have vast potential as medicinal tools as well they are banned and won't even be considered for research.
The fact that the US classifies substances like Cannabis, Psilocybin Mushrooms, LSD, Peyote, etc. as SCHEDULE 1 and as such having "no currently accepted medical use in treatment in the United States and a lack of accepted safety for use under medical supervision" is absolutely absurd and beyond rational defense. The only conclusion is corruption, bias, incompetence or (more likely in my opinion) a combination thereof.
