In case you missed it, Willie Nelson was on the Tonight Show starring Jimmy Fallon last night, and the country legend admitted marijuana saved his life. Watch below as Willie says he used to smoke 2-3 packs of cigarettes a day which led to several bouts of pneumonia, a lung collapse, and near-death. He decided to switch to weed and has since never picked up another cigarette. Willie also admitted he's CTO "Chief Testing Officer" at his weed company. Scroll down to watch Willie perform a cover of Guy Clark’s ‘My Favorite Picture of You’ from his new album Ride Me Back Home (out Friday) which he dedicated to his horses. You can catch Willie at his Outlaw Music Festival, July 3 at Dos Equis Pavilion
