Irvin Rosenfeld Nears Pot Smoking Record

Irvin Rosenfeld, a 56-year-old stockbroker from Fort Lauderdale, Fla. will smoke his 115,000th marijuana cigarette Friday, a possible world record, and he can thank the U.S. government for his supply.

"Yep, provided by Uncle Sam," Rosenfeld told NBCMiami.com. "They grow it for me, I find that quite ironic."

Since 1982, Rosenfeld has been a patient in the Federal Drug Administration's Investigational New Drug Program. He suffers from a rare bone disorder called multiple congenital cartilaginous exostoses. To alleviate the pain associated with the disorder he was prescribed marijuana.

The marijuana is grown on a farm on the campus of the University of Mississippi and is delivered to a pharmacy where Rosenfeld picks up a tin of 300 federally grown and rolled cigarettes that have been sent for him. He said he smokes between 10 and 12 marijuana joints per day.

"The first thing I do every morning is smoke two joints as I watch my business shows," Rosenfeld said. "Then another on my drive to work."

According to Fortune magazine Rosenfeld is one of four people in the United States whom the federal government supplies with medical marijuana.

His marijuana use has led to comical moments at his office. Marijuana "has a distinct smell," said an executive that works with Rosenfeld to USA Today . "The mailman or someone coming into the building will stop and notice."

NBCMiami.com. reported that Rosenfeld is writing a book on his experiences as the nation's longest-running legal pot-smoker, tentatively called "Potluck." He hopes to have it published in the spring. But he expects Friday, Nov. 20, he will set a world record for marijuana consumption when when he lights up No. 115,000.

Earlier this month, the American Medical Association moved closer to supporting medical marijuana, adopting a measure urging a federal review of marijuana's status as a controlled substance, reported The Associated Press. The group said its position doesn't mean it supports legalizing marijuana.
