You mean decriminalizing hard drugs had a down side?????? Who could have predicted that!?
The problem wasn't the "decriminalization", the problem was that it was rolled out as an effort to HELP people on drugs find treatment but none of the infrastructure was put in place to ensure that it was going to be done.
It's like when America decided to close down all the mental hospitals. The "promise" was that community centers would be put in place to take care of these people but funding for THAT never materialized leaving us with mentally ill people and no place for them to be helped in any way. So our homeless populations of the mentally ill exploded. NOT because we weren't horrible enough to the mentally ill but rather because we only did HALF THE WORK.
Drug criminalization is a fraught topic and other experiments will have to be undertaken because simply throwing people in jails for drug abuse doesn't appear to be "winning the war on drugs" in any real way.
