When will we all grow up?  Kellogg has now dropped Michael Phelps as a sponsor because he was smoking pot at a party. He was also suspended by USA Swimming for three months. Marijuana kills exactly zero people every year.  But yet, we continue to vilify people who use it and spend billions of taxpayer dollars every year in a futile attempt to eradicate it.   The DUI that Phelps got in 2004 is infinitely worse than him smoking pot at a party.  A DUI directly puts the lives of other, innocent people at risk.  Why didn't Kellogg or USA Swimming have a problem with him driving drunk?
