CNN’s Marijuana Documentary “Weed 3″ Airs

CNN’s chief medical correspondent Dr. Sanjay Gupta has returned with more revelations about medical marijuana with his latest documentary, “Weed 3: The Marijuana Revolution,” which originally aired on April 19 (and can be viewed below).

The documentary discusses medical marijuana and examines the lives of families that benefit from it. Gupta also gives viewers an insider’s look at the politics behind medical marijuana research.

Weed 3 also focuses on the efforts of the Multidisciplinary Association for Psychedelic Studies (MAPS), whose researcher Dr. Sue Sisley is attempting to get federal approval to study marijuana’s effect on Post-Traumatic Stress Disorder (PTSD), after a series of bureaucratic setbacks.
