By now it's obvious within the cannabis community how much of a boost the plant can be for general wellness — but within the world of professional sports, only a handful of athletes have come out of the cannabis closet to advocate for its medicinal uses. Among them includes Al Harrington, former NBA player and founder of Viola, a cannabis brand named after his grandmother. Nearly a decade ago, Harrington helped Grandma Viola discover cannabis as a treatment for her glaucoma. He's since also used it to treat his own knee replacement, and is on a daily CBD regimen, as well. But while cannabis can be especially helpful as a tool for athletes to boost their wellness and heal their injuries, professional sports leagues have been slow to catch on, with players still subject to drug testing. Hopefully, Harrington says, at least CBD can help to break down the barrier.
