POLICE are looking for a woman who was photographed smoking what looked like a meth pipe while driving.

A witness saw the woman use a bright green lighter to heat the bottom of a glass pipe yesterday afternoon on Kwinana Freeway heading south near Thomas Road.

The driver who saw the woman said her car was swerving all over the road. He asked his wife to photograph the woman and her car’s registration plate.

Premier Mark McGowan was shocked by the photograph.

“One of the most insane things I’ve ever seen,” he said. “Stupid crazy stuff. I look forward to police tracking her down and charging her.”

Shadow police minister Peter Katsambanis was equally shocked.

“These people are crazy,” he said. “They need to stop this sort of behaviour.”
