any addict who WANTS to quit and stay quit CAN do so.....with or without rehab. for YOU, you had the desire and commitment and treatment gave you the start on your sober path.
but each addict is different.....and what works for one might not work for another. there are addicts who have been to treatment 4, 5, 10 times and still use. there are those who got it right the first time.
i am really sorry that the centers he has contacted are not being cooperative. that doesn't "help" the situation. perhaps he should contact his INSURANCE and get a list of available options from them.
i understand that sense of obligation......but you might not be able to HELP him with this. your sobriety is very precious....and someone using black tar heroin IN your home is a threat to that.
