1. Portugal: The first country in the European Union to decriminalize all drugs has seen a decline not only in arrests, but in illicit drug use overall. While there are still small fines for selling drugs, the country’s focus is on rehabilitation, harm reduction and treating addiction as a disease.
Well, DUH. When all drugs are decriminalized why wouldn't you see a decline in illicit use over all? If they are legal I believe that makes them are no longer illicit.
