Strawman. You aren’t legally allowed to make ecstacy at home even if you are capable, nor are you allowed to consume it if you have it. Also, ecstacy wasn’t illegal during the prohibition. That’s all irrelevant.
People should be allowed to do what they want as long as it doesn’t pose a serious risk to others. Racism is most of what caused the war on drugs, and it’s mostly futile, and often actively harmful. It prevents people from accessing things that may help them (or they may just enjoy), and creating black markets where none need exist. It also creates situations where people may buy stuff and it not be pure, which could be controlled for if legal.
