Michael Phelps, 23, caught on photograph apparently smoking marijuana, has lost Kellogg as a sponsor and was also suspended for three months by USA Swimming.

Phelps, who won eight gold medals at the 2008 Beijing Olympics, was featured on Frosted Flakes and Corn Flakes cereal boxes. The drug association was apparently too much for the U.S. food company to take.

Other sponsors – Speedo, Omega, Visa, Mazda and Subway – have not withdrawn their sponsorship of the swimmer.

The dangers of marijuana, known also as ganja, include distorted thinking, extreme depressions and paranoia.

All things considered, it could have been worse. If he was caught smoking marijuana in Singapore, he would be facing up to 10 years in jail or a S$20,000 fine, or both.
