He’s apparently been avoiding one of the most famous movie lines and lessons of all time — “don’t get high on your own supply,” as Michelle Pfeiffer once said in “Scarface.”

Tyson admitted that he smoked marijuana during the day of his exhibition match versus Roy Jones Jr., immediately after the fight, as well as all throughout training camp.

“Absolutely yes,” Tyson said. “Listen, I can’t stop smoking. I smoked during fights. I just have to smoke, I’m sorry. I’m a smoker. … I smoke every day. I never stopped smoking … It’s just who I am. It has no effect on me from a negative standpoint. It’s just what I do and how I am and how I’m going to die. There’s no explanation. There’s no beginning. There’s no end.”

When asked if smoking pot helped Tyson deal with the pain of the punches he absorbed in the ring, he said: “No, it just numbs me. It doesn’t numb the pain.”

Tyson has previously abused cocaine, but his substance of choice these days is weed.

Marijuana has always been prevalent in Tyson’s life dating back to his childhood days growing up in Brownsville, New York. Indulging in marijuana carried over to his professional career, as he tested positive for the substance against Andrew Golota in 2000. His two-round stoppage and win was changed to a no contest, and Tyson was forced to pay a $200,000 fine.

Tyson’s preference for marijuana even led him to use a prosthetic penis with his child's urine during his prime just so he could pass drug tests.

Tyson said his self-destructive days are a thing of the past, and now he just wants to help others by boxing in exhibitions for charity.

“In a perfect world, I’m a missionary,” he said. “I’m here for a purpose … I’m not here for my ego. My ego is taking the money, buying some planes, some nice houses, packing up a bunch of chicks and have some orgies and stuff.

“This is not who that is right now. That guy was just somebody that had to be. Eventually, he was a platform to become me.”
