A Sheffield woman who was driving a car which reeked of cannabis was found to be three and a half times the legal limit.
On July 24, a student officer stopped a vehicle on Sicey Avenue in Shiregreen which smelled heavily of cannabis.
The female driver was given a 'drug wipe', tested positive and was arrested for drug driving.
The blood sample she gave for further analysis has now come back showing she was three and a half times the legal limit for cannabis and will be reported on a summons.
A statement on the police's Facebook page said: "It’s simple, if you drug drive you are risking people's safety. "
"We will test you if we suspect drug driving and guess what, if you refuse the test, you get arrested.
"If you prove positive, you get arrested. Just don’t do it."
