Cambridgeshire Police are launching a crackdown on drug driving from today.
The two month campaign will see more patrols aimed at tackling the problem.
The Department for Transport estimates that drug impaired driving resulted in 141 deaths and 651 serious injuries in 2014.
The penalties for drug driving are the same as those for drink driving. If convicted, motorists could lose their licence, be fined up to £5,000 and even face a prison sentence.
