I'm confused. I've seen addiction twice with people who were very close to me and it was a terrible thing, but I know that banning drugs is not the answer. In at least one of those cases however it was a case of alcoholism, not addiction to class A's. We need to think outside the box to deal with this problem.
Honestly, I guess legalization of the less harmful (non-physically addicting, not causing psychotic breaks, etc.) drugs and placing those under official control could remedy the problem. I doubt people take drugs to go on killing sprees, they probably take them for the same reason they drink or smoke (which I don't indulge in either) - to feel the pleasant effects of the drug. Thus, making them available and controlled would reduce the danger to the drug users, cut the profits from criminal organizations, and so on, but I am quite ambivalent towards this solution.
Also, the problem with addiction is twofold: first, physical addiction, caused by the integration of drugs' effects into normal functioning of the body, so when it is withdrawn, body freaks out, usually in the opposite direction to the drug's action. This includes alcohol, which has a depressing action, so when it is withdrawn, the neural system results in excessive excitation, when you think of it. Curing physical addiction in itself is the issue of restoring the body's functions back to the state where it works without the aid of drugs.
Then there is psychological addiction, which the root of the problem. People take drugs and experience positive reinforcement, they are more inclined to take them again. People take drugs and feel bad when they stop taking it, they are less inclined to stop taking them. Conditioning at its most basic form. And reason why would they use drugs in the first place? There are so many possible reasons that it's not even worth going there.
