A comedian who based his career off the reefer says it saved his life.

Last week, Tommy Chong posted on CelebStoner that hemp oil helped him beat prostate cancer. The 74-year-old comedian added that the marijuana-based product used in conjunction with a supplemental diet and a session with a “world-renowned” healer brought his cancer threat down.

“That's right, I kicked cancer's ass! So the magic plant does cure cancer with the right diet and supplements,” Chong wrote.

Chong was diagnosed with prostate cancer last June. According to his post, Chong said he was recommended an intense treatment in Mexico, which cost $25,000. He sought an alternative and found a Canadian doctor who recommended a different diet and “hash oil.”

“I'm due for another blood test, MRI, etc., but I feel the best I've felt in years. And now for a celebration joint of the finest Kush,” Chong wrote.

Chong has advocated for the legalization of marijuana in the United States. He thinks that legalizing pot on a federal level would alleviate the country’s economic woes.

"Look at the situation we're in now. Sequesters. Cuts. Everything cut across the board. Now, the government is tapped into the biggest cash crop in the world," Chong told AP. "There's little manufacturing cost. You don't have to do anything except watch it grow and get a couple of hippies to cut it and then put it in a bag."

Nearly 20 states have legalized marijuana. Vermont plans to decriminalize marijuana in small amounts. Colorado and Washington have made pot legal altogether.

Chong told TMZ that weed has become mainstream. He points to celebrities who he says are major marijuana fans.

"I knew [Justin Bieber] was smoking before he knew it. Because of his music. Because of his dancing. The guy is a phenom. ... It's not just his looks. It's his talent. And you don't get talent like that by drinking alcohol. The herb, man! The herb!"
