This Sunday (April 19) at 9pm (ET/PT), CNN’s Chief Medical Correspondent Dr. Sanjay Gupta, who came out in support of the relaxing of U.S. marijuana laws back in 2013 and then doubled down on that support in 2014, will be examining the politics behind medical marijuana research in his latest documentary “Weed 3: The Marijuana Revolution.”


Dr. Sanjay Gupta’s documentary is expected to show “the remarkable and surprising faces of this revolution — smart, successful and suffering” in addition to “the heads of government agencies earnestly sharing their point of view, both Democratic and Republican senators, and even the President of the United States.”

In anticipation of the premiere, Dr. Sanjay Gupta outlines 7 uses for medical marijuana:

[su_quote]Pain – In the United States, pain is the most common condition for which medical cannabis is taken. Studies show the drug is especially effective against neuropathic pain, a type of pain involving nerve damage. Marijuana is less habit-forming than opiate drugs and carries virtually no risk of a fatal overdose.

Multiple sclerosis – Sativex, a pharmaceutical version of cannabis, is approved in 25 countries as a treatment for painful muscle spasms arising from multiple sclerosis.

Nausea – The munchies are no joke. Marijuana is sometimes prescribed to stop nausea or induce appetite in people who have trouble eating, including patients suffering from AIDS or going through chemotherapy for cancer.

Epilepsy – More than 100 families have moved to Colorado to access “Charlotte’s Web,” a cannabis strain that in some epileptic children seems to dramatically reduce seizures. Taken as an oil, the medicine is high in a chemical called CBD and low in THC, the component that makes people “high.”

Concussion – NFL commissioner Roger Goodell said the league is following the work of Israeli researchers who are exploring cannabis as a potential treatment for traumatic brain injury. In 2003, along with two colleagues, Nobel laureate Julius Axelrod, an American, obtained a patent on the drug for its anti-inflammatory and neuroprotective properties.

Alzheimer’s disease – In studies of rats, marijuana helps starve off memory problems and Alzheimer’s-like brain changes. A leading researcher said the drug’s iffy legal status has held up further research.

Bipolar disorder – A small study at Harvard found that marijuana seems to stabilize the brains of people who suffer from bipolar disorder. Some studies show the drug actually raises the risk of developing mental illness, but those findings are controversial.[/su_quote]
