Did you know that Portugal basically decriminalized all drugs in 2001? Take a guess what the results have been over the intervening decade. If you guessed that the results would be a drop in drug use, a drop in HIV cases arising from drug use, and a big jump in people in treatment programs, you’d be right. (I wish there was more in the article about the presence or absence of effects on criminal cash flow arising from the presumable price drop in a decriminalized environment.)
