A Lafayette man booked Wednesday is accused of possessing more than an ounce of synthetic marijuana that officers found during a traffic stop.

Darrell Duplechin, 27, was booked on a count of possession with intent to distribute Schedule I narcotics after an officer found 37 grams — or about $370 worth — of the fake herb hidden under the back seat of the vehicle, Broussard Police Chief Brannon Decou said.

The driver, stopped on a traffic violation, showed “signs of nervousness,” and the officer said he smelled illegal narcotics “emitting out of the vehicle,” Decou said.

Duplechin, who was a backseat passenger in the vehicle, claimed possession of the synthetic marijuana, Decou said.

He remained in the Lafayette Parish Correctional Center Friday evening in lieu of a $10,000 bail.
