Prohibitionists predicted the worst in 2000 when Portugal decided to decriminalize all drugs. Now the UN International Narcotics Control Board considers Portugal an example of how to do it right. Overdose deaths are down, HIV transmission is down, use hasn’t significantly increased. The key seems to be providing treatment to all who need it. I wonder how the cost of this plan compares to the cost of incarceration? Beyond the dollars, the social costs of the war on drugs are pretty steep.
