Michael Phelps made headlines when a photo of him smoking marijuana using a bong was published, but now it appears he may be in legal hot water. The 23-year-old Olympic swimming champ apologized for the photo, but a South Carolina sheriff says that Phelps may face charges. “If someone breaks the law in Richland County, we have an obligation as law enforcement to investigate and to bring charges,” Sheriff Leon Lott Jr. said in a statement to People.com. “The Richland County Sheriff’s Department is making an effort to determine if Mr. Phelps broke the law,” continued Lott. “If he did, he will be charged in the same manner as anyone else. The Sheriff has a responsibility to be fair, to enforce the law and to not turn a blind eye because someone is a celebrity.” Phelps, who won eight gold medals at the Beijing Games, verified the authenticity of the picture published in News of the World in a statement to Entertainment Tonight.
