what drug was it? How did you recover? how long was you addicted? how long have you been in recovery? are you still seeking therapy?

I have a 22 year old nephew hooked on heroin. This is causing are family much turmoil, He is going to rehab today, but only for 30 days. This is his second or third attempt to come clean and I seriously think he needs longer treatment. Any comments would be helpful . Thanks !!
