For those unaware, there's a school of thought that rolling while under the influence of good 'ol weed (aka mota or reefer or yerba or blaze, etc.) is beneficial to one's Jiu Jitsu. Mistake me if I'm wrong, but I believe the thought is that rolling while high aids in a grappler's creativity and focus. There are a few well known grapplers/fighters out there who publicly support marijuana use, most notably ADCC veteran and grappling pioneer, Eddie Bravo of 10th Planet Jiu Jitsu and Strikeforce Champ, Nick Diaz.
Crazy as it sounds, I myself often train under the influence of both Starbucks and Life Cereal combined, but that's just how I roll (literally).
Check out the video below. It's an interview-style statement from ILoveBJJ.com's Ken Primola on the subject. Ken seems like a level-headed, righteous dude and we've featured many of his techniques here at DSTRYRsg. Hear him out and see what you think.
