If you think that someone you know is abusing prescription drugs, you should ask them. Let them know you're concerned, and offer to help them.  Don't get angry or blame the person for his drug use.

Acknowledge that this is difficult. Don't preach to the person or talk to them when you're feeling hurt about the problem
