I'm going to post more - because I want those worried about their kids using drugs to have good information - support - encouragement.
These 2 sites are a place to start:
Intervene.drugfree.org - this site has FREE ebooks to download - one on Medications for Heroin Addiction.
http://www.heroinabuse.us/-this site has easy to read Heroin basics.
If you have insurance you can call Rehab facilities directly - yourself. If you don't have insurance check your local county Mental Health agencies - ask for guidance and referrals - there are programs to begin the recovery process everywhere!
