While the idea looks good on paper, I don't think you fully understand what addiction does to a person. It's not as easy as opening a rehab center , and people get better.
Physical dependency on drugs or alcohol is a horrible, horrible situation, and I say that as someone that has personally been there. Something like 85% of people that go to rehab relapse, usually very quickly.
I went twice, in a 4month window. Yet, even after the second trip I relapsed within a week, and every time the withdrawals get worse. I didn't get clean for good until I realized I was gonna die soon if I didn't quit. Rockbottom is a real place, and it scared me bad enough I haven't had a drink since then, 3.5 years ago.
Sorry for the length, I've seen too many young people whose life and families are ruined or they die from drug use.
