Things actually get better. As the article itself suggests:
Life in Casal Ventoso, Lisbon’s troubled neighborhood, has improved. And new research, published in the British Journal of Criminology, documents just how much things have changed in Portugal. Coauthors Caitlin Elizabeth Hughes and Alex Stevens report a 63 percent increase in the number of Portuguese drug users in treatment and, shortly after the reforms took hold, a 499 percent increase in the amount of drugs seized — indications, the authors argue, that police officers, freed up from focusing on small-time possession, have been able to target big-time traffickers while drug addicts, no longer in danger of going to prison, have been able to get the help they need.
I’m still waiting on why we need this “War on Drugs.”
