When it comes to Hollywood stoners, few have had more prolific cheefing careers than Woody Harrelson. From Cheers to Natural Born Killers, comedies to dramas and back again, Harrelson spent more than three decades of his high-profile career regularly stoned. But after more than 30 years of bong rips and “enough pot to fill a theater” under his belt, Woody put down the bubbler in 2016 and hasn’t picked it up since.

So, after a year and a half of cannabis abstinence, what’s been the hardest part of staying sober for the leading man who once made waves for his intense adoration of hemp clothing?

Like anyone who’s ever taken an extended tolerance break, Harrelson has struggled to explain his weed-free lifestyle to his still-smoking stoner buddies.

Unlike regular tolerance breakers, though, Harrelson is homies with cultural cannabis icon Willie Nelson, setting up a slightly more awkward scenario at his famous friend's latest smoke session meetup. 

In a recent appearance on Jimmy Kimmel Live, Harrelson explained just how much willpower it took to pass on a joint of Willie’s Reserve and divulge the secret behind his clear eyes to country music’s most noted smoker.

“That was a very hard one to break. It was one of those things where first I was pretending, just holding [the joint] because I don’t want him to know, and then finally I’m like ‘Willie I quit,’” Harrelson said. “And still, it never fails, the joint comes around and he passes it to me, he keeps waiting for me to smoke again.”

At least Willie is still fighting the good fight. 

As for Harrelson, he’s kept up his sober status with no signs of slowing down, but still hasn’t lost the perma-fried personality and sense of humor we’ve come to know and love. As Kimmel so astutely pointed out, “it’s called the lingering effects of marijuana.”
