It’s easy to favor drug legalization when you’re middle-class and well educated. Your social group probably doesn’t include many people who abuse drugs much in the first place. Moderate users can afford their habit. And when their use turns into addiction, they usually have a strong support network to help out. It’s a problem, but not a huge one. In poor communities, none of this is true. Drug addiction is financially ruinous. It often leads to petty crime. Support systems are nonexistent. The justice system is harsh. There are no rehab centers on the Malibu coast to help out. Drug epidemics — Oxy, meth, heroin, you name it — are devastating. It’s something to keep in mind when you consider both the costs and benefits of drug legalization. Ending the war on drugs would indeed be a huge benefit, but the costs might be higher than you think.
