It was a wrong change to outlaw drugs in the first place. Did you know drugs are illegal because it was beleived they caused interracial sex. I’m not making that up. It really is why the US outlawed “illicit” drugs. Also the only reason caffeine wasn’t outlawed is because Coca Cola was powerful enough to get it off the list.
Drug prohibition is every bit as wrong and damaging as alcohol prohibition was if not worse. The lobby’s against legalized drugs are almost exclusively those that make money from them being illegal. Alcohol and pharma and law enforcement. Follow the money. Drug prohibition causes far more harm than good and nobody that started or supports it ever had any altruistic intentions.
