YowYan, my problem is not with drugs being categorically "bad" (I would be lying if I said I have never experimented with them, though admittedly never illegal ones). The problem is that the more of these recreational drugs you legalize, the greater the economic burden a certain parasitic sub-culture of drug-addicts becomes.
I am not sure as to the extent that this would apply to the US but in England (my country), drug-addicts in general, from alcoholics to the guys in hard-rehab, are often inextricably tied to unemployment, criminality, the welfare system, and the cycle of poverty.
When you legalize cannabis, for example, without a doubt a significant proportion -maybe even a majority- of its user will be as responsible as people are with alcohol. On the other hand, you will almost certainly augment the aforementioned problem of the sub-culture of addicts, by whatever measure I don't know. But if that measure is significant, frankly, and especially in a welfare state like my own, I would basically end up paying the extra bill. And that is something I don't want to do.
So in sum, I have no problem with legalizing all the drugs you guys want (even the hardest of the hardest) but only and only if I am not living in a bloody welfare state. And one more thing: I don't want you guys complaining about that augmented parasitic sub-group as if it was the tax-payers responsibility after we legalize all those drugs.
