In my country they have made heroin legal (unofficially, as an experiment). The result is that those using heroin realize, when buying it in pharmacy, that they were just sick, and their consumption tends to diminish. But also, there is no newer incoming to it, as it has become a real medication, and not an appealing street marginal product. The net result is a quasi disappearance of heroin.<quoted text>I agree make pot legal, but not the dangerous drugs. You can't use psychology to make a hard dangerous drug legal. Too many people would die in that experiment.
At the opposite, in Russia, they have tried to eradicate heroin, literally. The result is that the heroin user have discovered a way to get similar effect, with common products accessible in all supermarket. They created krokodil(*), the drug which can "satisfy" the need of heroin, but which is far more addictive, and far most toxic, as you loose your skin, limbs, and eventually die in terrible suffering.
All experiences confirm that when you make a drug/medication illegal, it becomes quickly far more dangerous. And if you try to eradicate it, much worst will replace it.
