The 89-year-old actor said that he has been taking cannabis extracts such as CBD (cannabidiol) and THC (tetrahydrocannabinol) to help manage pain and swelling in his joints.

Speaking to the PA news agency, the Star Trek star said: “I’ve got some aches and pains I didn’t have a few years ago. But, I’m finding out there are many things that help aches and pains that we didn’t know about just a few years ago.”

He continued: “Well, THC and CBD, and that kind of thing. It’s magical. I’ve had swollen joints where it hurts, you rub some on and while you’re rubbing it on, the pain disappears. It’s magical.”

CBD and THC are compounds known as cannabinoids, found in the cannabis plant, and are legal in parts of the United States under certain conditions.

CBD is a non-psychoactive chemical compound found in the marijuana plant, while THC is the chemical in the cannabis plant that gives users a feeling of euphoria.
