Former Arizona Wildcat offensive lineman Eben Britton played in 60 NFL games from 2009-14, starting 34 of those with the Jacksonville Jaguars and Chicago Bears. And according to him, he played three of those games while high on marijuana. A not-at-all-surprising number was thrown out by Britton that somewhere between 50 and 75% of NFL players smoke weed. But his explanation of playing high was interesting:
"NFL games I played stoned were some of the best games I ever played. Cannabis cements your surroundings. A lot of people say they’re useless when they smoke weed.
