4x14 - Quincy, M.E.

A top children's TV star, and a friend of Quincy's, is shocked when his son dies of a drug overdose. He had no idea his son was even on drugs and is angry when he finds out that a doctor prescribed the drugs to him. Quincy and the star, Brock, go to visit the doctor and find an enormous queue of addicts waiting outside the surgery. They are all waiting with money in hand to buy a prescription from the doctor. Quincy and Brock set about trying to shut this doctor down and to help a young would be doctor in his attempts to get some sort of drug counseling support system set up in his college.
