Five Northland men have been convicted for driving under the influence of drugs, with sentences ranging from fines to community work, and all were banned from driving.
Figures released by police late last year show that more than 90 per cent of motorists in Northland tested for driving under the influence of drugs have illicit substances in their blood, including cannabis and methamphetamine.
By the start of October last year, 67 people had been convicted of driving under the influence of drugs, but many more had been caught since.
Five more men have appeared in court charged with driving while their blood contained evidence of a controlled drug.
David Thomas Beachen, 21, appeared in Whangarei District Court after tetrahydrocannabinol (THC), the active ingredient of cannabis, was found in his blood in July. Beachen was fined $500 and disqualified from driving for six months.
