Don't forget that sometimes doctors will prescribe medications because they know the medical history of the patient. I think sometimes they justify it by calling it "maintenence" Some people have to use these drugs daily in order to live somewhat a normal life. The downside to this being the unwanted side affect of addiction. Not to mention the long term effects from taking that kind of drug. I fault no one who needs the drug to control pain.

He should live by example now. Go get treatment and if he's broken any laws he should have to face the consequences just like the rest of us would. That would probably be his opinion if it were someone else.
