Well, we're not here just to agree with what everyone posts, I would think that it's expected at some point.
There's nothing written in stone that legalizing the more hardcore drugs would likely reduce addiction rates. I've seen the effects first hand of what could happen if drug laws are non existant or aren't regulated or enforced in Afghanistan, more than half (at least the males) the population of a village being heroin addicts contrasted to a village of the same size and likeness where it was heavily controlled, regulated, and the laws were enforced - the addiction rates were much lower, the differences in the standards of living (even though it was Afghanistan) were drastically different.
You can be an alcoholic and recover and live a whole lot more than if you were a heroin addict trying to recover, same goes for meth and crack cocaine...it's not the same thing, that'd be like trying to compare methadone to Chantix at the end of the day.
I'll be the first to say that the War on Drugs is stupid, it doesn't mean that there should be a free for all on those drug types that're hardcore enough that it'll only take one or two hits and you're an addict, that once an addict there's a good chance you're not gonna live through the rehab trying to kick the habit.
Not much to do with the price of tea in China.
Sounds more like your opinion, unless you've got some data that proves drug cartels would just keel over and die at the whim of all drugs known to mankind being legalized...works both ways...nonetheless, I did point out the Opium Wars, data wise it's estimated that more than ten percent of the population in China became addicts, it wasn't til opium became a controlled substance (on mainland China, Hong Kong however was a different story altogether) did the rate drop.
