i dont know if i would consider psychedelics in the same way i would meth or heroin. im sure some people are dumb fuck addicts who fried their brains from psychedelics, but i never got a hint of addiction to them. most of the time i took some sort of psychedelic, i didnt feel like doing it again anytime soon.
i doubt society would be any worse off if they legalized marijuana for recreational use. it is a bit retarded to allow alcohol instead, which i can attest is a very dangerous substance. weed might make me act a little retarded, but alcohol causes me to lose control of myself. that said, no drug should be an excuse for belligerence. there should still be severe punishment for people being assholes in public due to any drug the same as there is for public intoxication. people who cant mind their dosage or are plainly unstable anyway dont have any business using mind-altering substances. maybe people should be required to certify their knowledge of particular substances (potentially undergoing clinical trials of different substances to see if they can be handled, too) before they can legally use them.
