Tommy Chong revealed on social media that he is again battling cancer.

Chong said in a tweet, “I have good news and bad news. First the bad news, the cancer came back and it’s a real pain in the butt. The good news is I now have to use more marijuana to treat the cancer.”

“I’ve had some medical issues lately,” Chong, 77, told Us Weekly on Tuesday. “I got diagnosed with rectal cancer.” “I’m in treatment now,” he added. “Either I get healed or I don’t. But either way, I’m going to make sure I get a little edge off or put up.” h/t abc

Chong added, “I will be documenting my cancer fight on the Chong and Chong podcast to let my fans know how the fight is going. Please wish me luck while I kick cancer’s behind. Thank you for all of your love and support.”
