Kevin Smith said his massive heart attack didn’t kill him thanks to a joint he smoked before his health scare in February.
The 47-year-old director visited The Late Show on Tuesday where he revealed that his doctor said smoking marijuana saved his life because it calmed him down.

“I said, ‘Doc, honestly, I just smoked too much weed this morning. That’s what this is,’” Smith said.
“I honestly thought I was too high. I’d smoked a bunch of weed that day because I was doing the show and then I smoked a joint right before the show and then I got off stage and all of a sudden I had a heart attack,” Smith explained.
The Clerks star asked the doctor if the marijuana could have caused his health scare.
“He goes, ‘No, quite the opposite. That weed saved your life.’ And I was like, ‘Do tell! Like, what do you mean?'” Smith continued. “He said, ‘You kept calm. They told you (that) you were having a massive heart attack, and you remained calm the whole time, so that joint saved your life.'”
Smith joked that he was going to put what the doctor said on a T-shirt.

He shared a photo of himself in the hospital.
“After the first show this evening, I had a massive heart attack,” Smith tweeted. “The Doctor who saved my life told me I had 100% blockage of my LAD artery (aka ‘the Widow-Maker’). If I hadn’t canceled show 2 to go to the hospital, I would’ve died tonight. But for now, I’m still above ground!”
Smith said that after completing the first of two Kevin Smith Live! shows at the Alex Theatre, he threw up, then “started sweating buckets and my chest felt heavy.”
Since the heart attack, Smith has been focusing on living a healthier lifestyle.
