He’s not quite 420 blazing it, but X Men star and veteran actor Sir Patrick Stewart revealed this week that he uses daily medical marijuana to treat his arthritis.

The 76-year-old made the confession as a show of support for a new Oxford University research initiative that aims to explore the benefits of cannabis-based medicine—the first of its kind in the U.K.

“This is an important step forward for Britain in a field of research that has for too long been held back by prejudice, fear and ignorance,” he said. “I believe this program of research might result in benefits for people like myself as well as millions of others.”

It turns out the actor, who lives in Brooklyn, New York, but also spends time in Los Angeles for work, has been using cannabis for years in a spray form.

“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 explained.

So there you have it. If Captain Picard is cool with weed, there’s no reason the rest of us shouldn’t be too.

Between this and his new foster dog, he has to be in the running for Most Millennial Septuagenarian.
