NASHVILLE — Willie Nelson’s famous habit of smoking marijuana is not seen as a badge of outlaw courage here anymore, so much as the frivolous foible of an eccentric uncle. A popular FM station disgorging the Boomer rock hits of yesteryear calls itself Hippie Radio 94.5; one of its sponsors is a smoke shop that incessantly hawks glass pipes and detox kits. Even mainstream country acts mention smoking marijuana now and again among the litany of acceptable American pastimes.

So perhaps it is not surprising as much as telling that this city, which residents often refer to as the Buckle of the Bible Belt, may be on the cusp of joining the long roster of American cities, including New York, that have decriminalized the stuff.

On Tuesday, the Metropolitan Council, the legislative body for the consolidated city-county government here, will vote on a proposed ordinance that would give the police an alternative to criminally charging people caught with a half-ounce of marijuana or less.

Under the ordinance, officers will have the discretion to forgo a misdemeanor charge for marijuana possession, and instead issue a civil citation with a $50 fine. A judge could then suspend the civil penalty if the person cited agrees to perform up to 10 hours of community service. The goal here, as elsewhere, is to keep minor drug offenders from clogging the court system, and relieving them of the stigma of a record.
