You can hit a wall for getting high. Anyone who’s ever been an all-day everyday stoner knows it. At a certain point, your tolerance gets so high that the THC just doesn’t have the same old effect anymore. When this happens, at first you can just step up the quantity, but then you reach a point where the quantity can’t really get any bigger and you’re still not gettin high.

With dabbing, the problem is even more exaggerated. Someone who dabs all day isn’t going to get anything from a few puffs on a spliff. They might not get anything from a gram of wax.

Movie star/true detective/white-man-who-can’t-jump Woody Harrelson may have finally hit that THC tolerance wall. What’s for certain is that the actor says he hasn’t used cannabis in nearly a year. In an interview with Vulture regarding his soon-to-be-released indie comedy Wilson, Harrelson said that after “30 solid years of just partying too fucking hard,” weed just isn’t doing what it once did for him.

Marijuana, he said, is “a great drug, in terms of… euphoria.” “But when you’re doing it all the time,” he continues, “it just becomes … Well, you know. I feel like it was keeping me from being emotionally available,” which sounds like weed used to make the actor feel great, but now that he’s used it so much for so long, it’s making him feel not so great.

Despite having quit the cheeba, the actor said he’s still a “party animal.” He still drinks, he says, and he apparently has a notorious trailer he brings on the set of each film he works on for the purposes of partying down. Donned “The Mothership,” the trailer is actually a refurbished bus that’s already been redone three times over since 2001, including having the engine replaced. “It’s a giant money pit,” Harrelson says, “but I still love it. I love her.”

And he’s been tempted to fall off the cannabis wagon he’s been riding almost a year now. Being not just a pothead who’s famous, but someone who’s famous for being a pothead for so many years probably makes it hard to shake off the offers. “Well, like, last night, someone had — not just good herb but sativa; really good sativa,” Harrelson said.

“There’s a joint, and beautifully rolled. I like a beautifully rolled … and I just was like, I mean, I’ve gone this long. It would be weird to just be like, “Okay, let me have a hit off that,” and then suddenly go back to smoking too much.”

Guess that means he probably won’t be opening that dispensary in Hawaii after all.
