How to help son
 

How can I help my adult son with his alcoholism problem? He drinks a little for his back pain.

does he want help?

I honestly couldn't tell if you were serious or if you were messing around. Still don't know. On the chance you are being serious, I'll say, consider going here:

Friends and Family of Alcoholics - SoberRecovery : Alcoholism Drug Addiction Help and Information

Great people with brutally honest advice. If you are messing around, just realize there are a lot of people here in pain trying to reach out for help. Please respect that.

Send him to a pain management team, there are ways of dealing with pain that don't involve self-medicating through alcohol or drugs and there are non-narcotic pain relievers.
