See Vancouver's Insite program for proof it works. It's been a huge economic and social success, allowing timely intervention to help drug users get clean, reducing the rate of HIV and HepC amongst intravenous drug users and helping numerous people get a fresh start at life.
No - this is not true. OD's are at an all time high in the region [1]
It's a highly politicized issues and the entities behind it are strongly incented to make it seem as though it's working.
The only evidence of Insite 'working' is provided by them - and the data points they provide are selective, unscientific and definitely not objective.
There is no objective evidence to indicate that 'it's working'.
If it were a success - we should see number of users down, crime down, cleaner neighbourhood etc. - but no. None of that.
There has been no effect on the overall drug using population. There are no external metrics for success at all.
By 'success' Insite points to the 'number of ODs prevented' the number of 'addicts into programs' - but this assumes that those ODs would have resulted in death or would not have been dealt with otherwise, and that there are not other ways to get people into recovery programs.
Given the amount of $$$ being spent on the clinic, I'm very doubtful that we can claim any degree of success.
It boils down to a cleaner place to shoot up - that's about it.
I think it's worth keeping open as a 'point of experiment' so that we can try different methods of approach - but it's ripe to call it a 'success'.
When numbers of users is measurably down, crime is down, that area is safe to walk in during the day (it's not as of now) - then we can start claiming success.
