*The Full Documentary is available Below*

This PBS documentary highlights marijuana’s ability to alleviate pain, treat epilepsy, and even cure cancer. But now that the cat is out of the bag, the stage is being set for Big Pharma to freely synthesize and patent marijuana’s healing components, not necessarily for the plant itself to become legalized.

Though mostly positive in its portrayal of cannabis, the PBS report does contain some sound bytes from Dr. Eric Voth, Chair of the Institute on Global Drug Policy, a longtime, and very outspoken, opponent of medical marijuana. But all in all, the documentary is a compelling and highly-informative piece that may help to eventually turn the stigmatic tides of fear and superstition that surround this taboo plant

Clearing the Smoke, reveals how cannabis acts on the brain and in the body to treat nausea, pain, epilepsy and potentially even cancer.

Extensive interviews with patients, doctors, researchers and skeptics detail the promises and the limitations of medicinal cannabis. Even though the video has an American perspective, marijuana use is illegal throughout many countries of the world for reasons that are not clear.

This video is important because it mainly investigates the scientific basis underlying the medical benefits of marijuana use instead of focusing on the social, political and legal hysteria that have been attached to it.

The paper mentioned in this video, Marihuana Reconsidered, was published in book form. The author, Dr Lester Grinspoon, is the world’s leading authority on marijuana. In this book, Dr. Grinspoon examines — and debunks — many of the common misconceptions about marijuana.
