Cannabis on it's own, when used responsibly, can enhance your life in many positive ways, physically and otherwise. As can a nice glass of wine or frosty beer. Even an occasional toot is probably alright. It's been shown that MDMA, LSD and mushrooms can be used for PTSD, anxiety and depression. Heroin for it's amazing analgesic effects. I think they should all be legal, educate people and let them decide for themselves. I have no problem with anyone's drug use until it starts to have detrimental effects on themselves and their families, just like any other sort of human behavior.
