Marijuana, once considered worthy of condemnation, has in recent years become a "medicine," legalized fully in four states, with others expected to follow. But the dangers are clear. According to Bennett's research, more Americans are admitted to treatment facilities for marijuana use than for any other illegal drug. Studies have shown a link between marijuana use and abnormal brain structure and development. From William Bennett comes a call-to-action for the 46 states that know better than to support full legalization, and a voice of reason for millions who have jumped on the legalization bandwagon because they haven't had access to the facts.
