Lots of athletes get paid by the CBD companies or offered free products in return for endorsement. They would say it's good that's how advertising works.

That being said I believe there is a place for CBD oil but I'm not sure easing the kind of pain athletes experience is one of them.

I was sponsored by a glucosamine company when I was a junior weightlifter and wasn't sure if it was doing anything for my knee pain but I would still promote it to get more free bottles.
