sorry, I don't accept your argument that drug addicts are not criminals, I can tell you there are hundreds if not thousands of drug addicts in Thailand that are criminals and/or involved in criminal activity.... how else can they buy their fix .... one would have to be very naive to think otherwise.
Everyone knows right from wrong ..... everyone chooses which path he or she takes, so a level headed kid at school would know that drugs are wrong so he's not going down that road even though his mate decides to try it .... So there's no excuse or argument that the drug addict choose his wrong path ... he made his choice .... surely you can understand that.
