I just don't see how this can work. I worked in the Downtown east side for years and got to know a lot of semi functional drug addicts (and some not so functional ones). The thing is - for the most part and by and large these are people who've given up and have made peace with the life they live and will not change without a very strong external motivating factor. I mean - death isn't scaring these people off for heaven's sake. Every one of them has friends that died of bad drugs and overdoses and yet they keep going.Today is the day for BC to decriminalization hard drugs such as heroin and fentanyl, as well as crack and powder cocaine, methamphetamine and MDMA.
You have to have a carrot and stick approach. The threat of something dire (like being locked up without drugs and going cold turkey) combined with realistic alternatives (fully funded recovery programs using the best of the best techniques).
I don't want to use the word 'lazy' but it's sort of like that - addicts follow the path of least resistance which means keeping the status quo if they can and only changing if they have to. Make it so they have to and then give them an opportunity and you will get some results.
And even then the success rate is only something like 20 percent. Which is probably going to be about 21 percent more effective than this.
All you do by 'removing the stigma' is make it easier for them to maintain the status quo and eventually they will still get into bad drugs and killed. And fewer will seek help.
