WASHINGTON -- Drink and drive and it's grrrrrrrr-eat! Smoke pot and your flakes are frosted, dude.

So seems the message from Kellogg, which has decided not to renew its sponsorship contract with Michael Phelps after the Olympian was photographed smoking marijuana at a party in South Carolina.

That's showbiz, of course, but the cereal and munchie company had no problem signing Phelps despite a prior alcohol-related arrest. In 2004, Phelps was fined and sentenced to 18 months probation and community service after pleading guilty to driving while impaired.

The silliness of our laws -- and the hypocrisy of our selective attitudes toward mood enhancers -- needs no further elaboration. Even so, things are getting sillier by the minute.

Richland County (S.C.) Sheriff Leon Lott has now made eight pot-related arrests based on the snap that shot around the world. Seven were for possession and one for distribution, after deputies used warrants to enter the house where Phelps allegedly was photographed.

Phelps may be next.

In an earlier column, I gave Lott the benefit of the doubt, suggesting that his hands were tied given the laws of the land and South Carolina's political climate. I retract the benefit.

Sheriffs, though elected and therefore political, have great latitude as to what crimes they pursue. In a state that recently ranked among the most dangerous in the nation, one would think South Carolina's law enforcement officials have better things to do.

Indeed, they do. In our peculiar obsession to track down the Willie Nelsons, Rush Limbaughs, and now Michael Phelpses of society -- nonviolent, victimless imbibers of drugs -- we've actually made society less safe. That's the conclusion of 10,000 cops, prosecutors, judges and others who make up the membership of Law Enforcement Against Prohibition.

Howard Wooldridge, LEAP's Washington representative, is a former cop and detective who lectures civic clubs and congressional staffers on the futility of drug laws that reduce public safety by wasting time and money. He points to child pornography as just one example.

As of last April, he says, law enforcement had identified 623,000 computers containing child pornography, including downloadable video of child rape. Only a fraction of those have been pursued with search warrants, thanks to limited resources and staff shortages. What's worse, Wooldridge says, is that three times out of five a search warrant also produces a child victim on the premises. Continued...
