This is Your Brain.
This is Your Brain on Government Propaganda.

The Director of the Office of National Drug Control Policy - the nation's "Drug Czar" - writes in the Washington Post today about the terribly harmful effects of marijuana. According to him, "Research has now established that marijuana is in fact addictive." It has? I must have missed that announcement. In an effort to get his audience to take the demon weed seriously, he informs us flatly that "Marijuana directly affects the brain." That it does, and a good thing too. Drugs that work only through the power of persuasion generally have little recreational value.
