There's a very sad story of a kid who told his DARE teacher that he found a couple of joints in his parents' room.

This resulted in his parents being led away in handcuffs, and the children being taken away by social services, in tears. When he was asked about it, he said, "They told us that people who used drugs need help, and I just wanted my parents to get help."
