ANYBODY can buy and do hard drugs NOW... that's the entire point. The "war on drugs" isn't deterring ANYBODY. The only people facing hard sentences are dealers... and there certainly is never a shortage of those lining up to take over for the ones who get busted. And fucking lol that America will turn into Afghanistan if heroin was legalized. Fucking dirt poor goat herders without a single modern convenience fall pray to hard drugs because they have almost nothing else to live for? Color me shocked.
Heroin is essentially legal NOW for users. Where have you been the last 50 years? I grew up experimenting with whatever drugs I wanted... and was offered a bunch of shit I didn't want and never tried. Never once did I think to myself "oh shit bro, don't light that spliff... what about the DEA?" Are you fucking delusional? You could have the Wolfenstein version of "robot Nazis won WW2" in power and there would still be a thriving black market for drugs. The shit is too easy to make, transport and use. That's the long and short of it. Set as many billions of taxpayer dollars on fire as you like, but it is what it is. You aren't going to stop the supply. If you stand any hope, you can only try to reduce the demand by having an otherwise prosperous and functional society.
