Weed Country, a new six part series premiering Wednesday, February 20 at 10 PM E/P on Discovery Channel, will go inside the world of growers and dealers looking to engineer some of the most powerful marijuana on earth and doing their best to keep out of jail. Today 18 states and Washington, D.C., have legalized medical marijuana. Washington state and Colorado recently approved marijuana for recreational use and at least 10 more states are expected to consider similar legislation this year. But for the pot farmers in states that have harsh laws, the risks are great. A marijuana farm with over a thousand plants could land someone in jail for up to 40 years. Many of the growers believe it's their duty to supply the plant for much needed medicinal purposes. Any other flower that had these medical properties would be treated as the greatest discovery to happen in this century, said Nate Morris, who began growing marijuana at just 14 years old and hopes to turn the plant into a medical game changer. - National Geographic
