On Jan. 31, 2009, a photo taken on Nov. 5, 2008 of Michael Phelps smoking a bong at a party in Columbia, South Carolina appeared in several tabloids and spread like a wildfire through the media. Phelps was quick to call his use of marijuana "bad judgement" and a "mistake."
He was suspended for three months by USA Swimming and lost his Kellogg's sponsorship. However, Phelps never failed a drug test.
He's since gone through rehab for alcohol abuse after his second DUI in 2014, so it's probably fair to say Phelps has put the bong down.
