Willie Nelson was charged with marijuana possession after six ounces of weed was found aboard his tour bus at a checkpoint in Texas yesterday. Patrol spokesman Bill Brooks said an officer smelled weed when the bus door swung open for a second. Nelson, 77, who recently told us he prefers to smoke with a vaporizer, admitted the marijuana was his and was held briefly before posting a $2,500 bond. A court date has yet to be set, though the singer could face up to 180 days in county jail, according to a local sheriff. That scenario’s extremely unlikely, but commence the “Free Willie!” campaigns anyway. [NYT, El Paso Times]
