A Stratford man has been warned against using synthetic cannabis after he pleaded guilty to disorderly behaviour.

On May 11, Luke Pratt, 19, was found unconscious in a car in Whanganui after consuming alcohol and synthetic cannabis.

Police prosecutor Drew Morrison told the Whanganui District Court on Tuesday that Pratt said he thought he was in Stratford when spoken to by police.

He was taken to Whanganui Hospital for detoxification at about 4.30pm. At 6.40pm, he discharged himself and was found walking around in the car park.


Later that evening, Pratt walked out of the Whanganui Police Station on Bell St and smashed the window of a car.

"He knows he's been the author of his own misfortune," Pratt's lawyer, Stephen Ross, said. "It seems to be a good example of why people shouldn't smoke synthetic cannabis."

Judge Chris Sygrove said Pratt's behaviour was well below the standard society required of him. "You should desist from using both those substances."

Pratt was fined $250.
