Patrick Stewart just admitted to getting stoned — but for good reason. During a new interview with The Telegraph, the actor admitted to using marijuana after the interviewer noticed his finger and thumb joints were knobbly, swollen and arthritic-looking, but flexible.

The interviewer suggested that Patrick was on steroids, but he quickly clarified. The Star Trek actor, 78, instead revealed he’s hooked on marijuana to help treat his ongoing arthritis battle!

“Medical marijuana — let me be very clear about that,” he revealed during the sit-down with the news outlet.

“I have cream, which contains cannabinoids, that I put on before I left the house this morning. I have a marijuana spray, which is fantastic. But it’s the cream that has given me this flexibility.”

That said, Patrick further explained his support of getting medical marijuana legalized in the U.K. “It’s a real battle, but we’re trying to change the law. People far sicker than me have had such benefits from cannabinoids,” he shared.

Patrick also opened up about his usage of medical marijuana in early 2017. “Two years ago, in Los Angeles, I was examined by a doctor and given a note which gave me legal permission to purchase, from a registered outlet, cannabis-based products, which I was advised might help the ortho-arthritis in both my hands,” he said in a statement at the time.

“I purchased an ointment, spray and edibles. The ointment, while providing some relief from the discomfort, was too greasy to use during daytime and so I only use it at night,” he said. “It helps with sleep as the pain was reduced. The spray, however, is much more usable and I spray my fingers and particularly my thumb joints several times a day,” Patrick continued.

At the time, he gushed over the positive results of the treatment. Patrick confessed. “I believe that the ointment and spray have significantly reduced the stiffness and pain in my hands. I can make fists, which was not the case before I began this treatment.”
