that if you legalized everything, every single problem you just cited above would be worse?
the best you can do is push back against the growth of the drug addled zombie underclass, and push back against the growth of the mafia, forever. NOT pushing back against these things simply means they grow and proliferate even more, to the destruction of far more rights and freedoms and destroyed lives than the war on drugs itself. you can't ever completely destroy the drug use, but that never was the point: the point is to simply minimize their stink
why can't you see that? why can't you appreciate the damage done by a large underclass of drug zombies and a fattened mafia from their existence? why doesn't your mind perceive of and understand the threat to individual freedom from those things?
here, learn your history:

here's the problem: teenagers are idiots. they think of themselves as immortal and immune, they don't perceive of the limitations of their willpower when faced, for example, with crippling addiction to something like coke/ heroin/ meth. and so, in an environment of easy access, a heck of a lot of them will try these things, and wind up with a life long crippling addiction
prevent them from accessing to these drugs though, and they mature to the point where they perceive on their own these substances have towards their quality of life and their freedom. of course you won't save everyone, some committed idiots are just hellbent on personal destruction. but a much larger class of casual idiots needs to be given the chance to escape the hell of addiction
i really wish you could understand and appreciate exactly what heroin, coke, and meth do to someone's lives and their minds and their freedom. of course the war on drugs has negative effects. i recognize and acknowledge every single negative you cite. now i wish you would acknowledge what free and unfettered access to heroin/ coke/ meth will cost in wasted lives, and see that it is far worse than the war on drugs
