Country star Willie Nelson has been cited for possession of marijuana and narcotic mushrooms after a Louisiana cop smelled trouble during a traffic stop. The singer's tour bus was pulled over early yesterday morning (18SEP06) and the cop insisted he search the vehicle after the whiff of marijuana hit him as he stepped onboard. State troopers claim they found over a pound of marijuana and less than a pound of magic mushrooms. Nelson and four others were issued misdemeanour citations for drug possession. Each was released after being issued a citation.
