I am all for the legalization of drugs, I agree with 144001 in that the justice system spends far too much of its resources trying to stop drug use and punishing those that do use. If drugs were cheap and available I think much of the crime associated with drugs would be eliminated, the huge profits that are reaped now from the sale of drugs lead to an incredible amount of death and mayhem as sellers seek to protect their turf and product. It seems we didn't learn much during the prohibition.
On the other hand, I don't think drug use is all that cool, and the potential for harm to others while under the influence is great.
