Insite works.  Supervised consumption sites are reducing the death rates per use -- but until and unless the number of people consuming drugs go down (via treatment or not consuming in the first place) nothing is really going to change.

Drug users have "freedom to choose" until addiction sets in - and then it will have them until either they get treatment or die.   Fentanyl or Carfentanyl only increase the probability of a bad outcome.

Recently spent 4 hours in an emergency ward while my mom was being treated/assessed after a fall -- and during that time several drug users were brought in by the paramedics.   Many of them sounded like they were frequent visitors based on discussions by the nurses/paramedics.

IMO, Seems like the definition of insanity -- drug users doing the same thing over and over again and expecting a different result.
