We were taught both sides of the story in our "drug diversion impact on public health" classes. Decriminalisation opens opportunities up to reduce harm to the public through reduced drug-related crimes, safer injecting (of the hard stuff) and less blood-borne viruses spreading. Australia has its own version of decriminalization known as the "harm minimisation policy". While all drug-related activities are illegal there, the judicial and healthcare systems are not so black and white about enforcing the laws.<p>Nonetheless, the other hand always wants its share. In the case of Australia, harm minimisation has reduced drug-related crimes, but the prevalence of drug use in the general population continues to rise, especially with regard to pills and amphetamines. Blood borne viruses are also on the rise, despite the ubiquity of safe injecting rooms in every major city and availability of "sharps kits" in every retail pharmacy.<p>Interestingly, the conservative party temporarily swayed from this stance and implemented a "tough on drugs" policy for part of the 90s[1]. It was dubbed to the wider public as a "harm prevention" measure i.e. protecting those yet to experiment with drugs and the wider community that didn't use illicit drugs regularly. There was a significant reduction in every measure: drug use, drug crime and spread of blood-borne viruses. This policy did not cut safe injecting and drug use services, but increased police activity and ephemeral "say no to drugs" cut-through education programs. The policy was reversed in the early 2000s.<p>[1] <a href="https://www.unodc.org/documents/ungass2016/Contributions/Civil/Dalgarno/30Years_of_HarmMinimisation_FinalUNGASS.pdf" rel="nofollow">https://www.unodc.org/documents/ungass2016/Contributions/Civ...</a>
