There are often negative consequences for society when someone becomes a drug addict. There are the costs to society at the macro level. And, of course, there's the devastation suffered by families.
Two logical fallacies; First, "use" does not equate to addiction by any means. The vast majority of people who try "addictive" drugs do not proceed to addiction or even regular use. Second, the costs to society are predominantly those imposed by society. The violence of the drug trade, the lives ruined by a drug arrest or conviction, the families broken up by incarceration of young men are all self-inflicted by society. Just having to deal with the ravages of addiction would be a welcome relief from all those things.
