Hooked: Illegal Drugs And How They Got That Way was a documentary that aired on the History Channel some years back--around the same time that the History Channel was still primarily the World War II Channel.
One thing that can be said of The History Channel, now simply called History, is that they are an incredibly timid, conservative channel. They want to insult no one, and worse still, have recently started catering to the lower common denominator in their show selection. While the LCD programming is a relatively new characteristic, they have always been conservative. That said, the fact that they were willing to air a series of shows that all but directly call our drug laws stupid is amazing. It should tell you how truly idiotic the laws actually are.
