Nate and Nick Diaz
Stoner siblings and UFC stars Nick and Nate Diaz are unabashed fandom of the green stuff. With Nate, the dude went so far to call himself the "Number One athletic stoner – besides Michael Phelps" and has no qualms lighting up his vape in front of the spotlight of TV cameras. Meanwhile, brother Nick has become the ultimate marijuana martyr after years of bong-inspired braggadocio. (The guy even once told the Los Angeles Times: "I can pass a drug test in eight days with herbal cleansers. I drink 10 lbs of water and sweat out 10 lbs of water every day. I'll be fine.") Unfortunately, Diaz was not fine. In 2015, the the Nevada State Athletic Commission suspended him for five years after failing a drug test in spectacular fashion. While it was later reduced, Diaz hasn’t been in a ring professionally since.
