If you become addicted while abiding to a prescribed usage and dose, I would suggest that it would be a case of overmedication, regardless.

Of course, if he did not over medicate himself to an addictive state he would not have been engaged with criminals at all.

You suggested that he overmedicated himself. If he was following a doctor's instructions I would be inclined to believe the blame doesn't fall so squarely on his shoulders for getting addicted. If, however, you are suggesting that a doctor's instructions should always be considered suspect and dangerous I guess I'd have to agree with you. There are a lot of highly respected quacks in medicine these days.
