Richland County Sheriff Leon Lott has told a local paper that he's considering whether Phelps committed a crime in his jurisdiction. That's right-- a record 8 gold medals at the last Olympics... and, Superman Swim-guy may see his cryptonite!

If charged and convicted of possession of marijuana-- the misdemeanor is punishable by up to 30 days in jail or a $570 fine plus court costs.

That picture seen around the world in NEWS WORLD, a British tabloid... just won't go away for Gold Medal Swimmer Michael Phelps. You can link to the pic of him smoking marijuana from a bong... something Phelps did not deny and has apologized for.

So far, Phelps' high dollar endorsements have not dried up-- Speedo and Swiss watchmaker, Omega issued statements that the pot-smokin' pic is a non-issue.

H-out
