Michael Phelps won 8 gold medals and he's a 'pot head'? At what point does this cease to be an "accusation"?

I'm not a drug activist, but why exactly is it that he may be charged with a crime? What's he done to harm anyone? He clearly hasn't harmed his career by being a pot smoker!







This will blow over, poof into a cloud of smoke.


I know, I know. But I couldn't resist.
