You get no argument from me on the need for increased treatment facilities.
I'm all for free treatment centers.
If fact mandatory treatment centers sound good to me. Get clean or we'll kill you !!
Of course the last line was a joke.
My point is, your friends got lucky. Any professional in the treatment centers you talk about that wants it to be legal is looking to increase their customer base. They all know that legalization will exacerbate the problem.
Making a problem legal doesn't fix the problem. Recreation drug use rarely helped anyone and contrary to you life experience, if you asked those people who quit you're likely to find a motivational experience that suggested they quit.
