In ‘Weed’, a one hour documentary, CNN’s chief medical correspondent Dr. Sanjay Gupta spends nearly a year traveling the globe to shed light on the debate. While it is part of a lifestyle for some, it is a lifeline for others including five-year-old Charlotte Figi. Charlotte suffers from a rare condition called Dravet’s syndrome, making her prone to up to 300 seizures per week. Like many people who use marijuana for medicinal purposes, parents Paige and Matt Figi tried every other option before resorting to this type of prescription. Dr. Gupta follows their journey. Gupta takes viewers to Colorado where weed dispensaries and pot cafes have become the norm. Dealers, doctors, users – Gupta meets with various people, like the Figis, offering a raw insight to what’s been dubbed “The Green Rush.” He also talks to experts about whether marijuana can be addictive-and whether it can contribute to long-term damage in the brain. Gupta’s final stops are in Tel Aviv and Jerusalem where he meets with some of the pioneers behind marijuana study, offering access to decades of innovative and cutting-edge research.
