Tommy Chong Diagnosed with Prostate Cancer

A sad day for ganja lovers indeed: Canada-born comic Tommy Chong, half of the sidesplitting duo Cheech and Chong, is battling prostate cancer.

The funnyguy said he first started noticing symptoms about eight years ago while in prison for selling drug paraphernalia. The official diagnosis came last month.

Chong, 74, made the announcement on Saturday night, during a chat with CNN about the legalization of marijuana.

The former That ’70s Show star described the disease as “a slow stage one [that I've] had for a long time.”

He told correspondent Don Lemon:

“I’ve got prostate cancer and I’m treating it with hemp oil, with cannabis. So [legalizing marijuana] means a lot more to me than just being able to smoke a joint without being arrested…I know it had nothing to do with cannabis. Cannabis is a cure.””

Chong said he hasn’t smoked marijuana in about a year for health reasons, but ingests hemp oil “at night, so I won’t be woozy all day. I’m taking it as a medicine.”

Chong and comedic partner Cheech Marin are best known for several films chronicling the adventures of the stoner pair. The duo first recorded comedy albums in the 1970s and hit the big screen in 1978 with the hit movie Up in Smoke.
