A woman who dropped a sachet containing a gram of methamphetamine (P) from her wallet as she was paying for petrol at a Westport service station was sentenced to six months' supervision.
Angela Dowler, 31, of Westport, pleaded guilty to possession of a class A drug, at the Westport Caltex on August 10.
Police said Dowler admitted having paid $150 for the methamphetamine earlier that day.
Lawyer Marcus Zintl said Dowler had admitted she had been smoking P recreationally at the time.
"She is remorseful," Mr Zintl said.
