Droves of moviegoers are lining up this weekend to see Logan, the latest film in the X-Men cinematic universe where Patrick Stewart’s Professor Charles Xavier and Hugh Jackman’s Wolverine have to deal with the stark realities of growing old and facing death.

But while the latest incarnation of the beloved Professor X is one of a run-down old man struggling with dementia, the 76-year-old Stewart manages to maintain his youthful vigor with the help of medical cannabis.

In a recent interview with Esquire UK, Stewart opened up about his use of a therapeutic spray to help with joint pain in his hands, which he believes keeps him in better health than his cinematic alter ego.

“I’m reflecting on aging anyway, it didn’t take Logan to make me think about that,” Stewart explains. “I think about it everyday. Not all the time. I’m not brooding on it, but I’ve come to a point where the numbers are against you. Physical things [make me feel old].”

“I mean, my main problem is my hands don’t work very well,” Stewart further added. “But thanks to cannabis they work much better than they used to. Thanks to the law in California now, it’s just a spray that I put on.”

Stewart’s use of cannabis spray is backed up by several clinical trials and studies proving that arthritis pain is one of the most common conditions that can benefit from medical marijuana.

Using medical cannabis also wouldn’t be such a bad idea for Stewart’s Professor X, with research indicating that marijuana can provide palliative relief for patients suffering with degenerative neurological diseases such as dementia and Alzheimer’s Disease.

As for Donald Trump’s regressive attitude against pot legalization, Stewart believes the current president likely won’t be a problem for much longer.

“Early on, I said that Trump would only make it two years. I’m now inclined to say two months,” said Stewart.
