(CNN) — Tommy Chong, one-half of the marijuana-loving “Cheech and Chong” comedy duo, is battling prostate cancer, he announced Saturday on CNN.

Having first noticed symptoms about eight years ago while incarcerated for selling drug paraphernalia, Chong said he was diagnosed “about a month ago.” He revealed his condition in an interview about his support for decriminalizing marijuana use and sales.

“I’ve got prostate cancer, and I’m treating it with hemp oil, with cannabis,” he told CNN’s Don Lemon. “So (legalizing marijuana) means a lot more to me than just being able to smoke a joint without being arrested.”
