Backstory: The Medical Marijuana Industry

Since the mid 1990s, 16 states and the District of Columbia have passed medical marijuana laws.

Journalist Jim Rendon went behind the scenes with many of the people who work in what is both an illicit and quasi-legal industry. His book is called Supercharged: How Outlaws Hippies and Scientists Reinvented Marijuana.
