On July 1st, 2001, Portugal decriminalized every imaginable drug, from marijuana, to cocaine, to heroin. Some thought Lisbon would become a drug tourist haven, others predicted usage rates among youths to surge.Eleven years later, it turns out they were both wrong.

Over a decade has passed since Portugal changed its philosophy from labelling drug users as criminals to labelling them as people affected by a disease. This time lapse has allowed statistics to develop and in time, has made Portugal an example to follow.
