Sergeant Meurig Jones of the North Wales Police Roads Policing Unit said: "Once again we are highlighting the number of drink and drug drive arrests on individuals who have shown a complete disregard not only for their own safety, but for the safety of other road users by taking to the roads whilst under the influence.
"Despite our repeated messages and warnings it is disappointing that we are continuing to make many arrests over what should be an enjoyable weekend for many.
"Several of these individuals now have an anxious wait ahead of them whilst we await the results of further tests.
"If convicted of drug driving they could face being disqualified from driving, receive a hefty fine, a prison sentence and a criminal record.
"A drug drive conviction also means greater insurance costs and the possibility of being unable to travel to countries such as the USA.

"People need to realise the consequences of their actions. A drink or drug driving conviction can be devastating, with significant criminal, personal, social and employment consequences.
"It will be harder for individuals to get to work, take their children to school and various other activities. They could even end up in prison. Worse than that – they could end up killing someone. Could you live with that on your conscience?
"Driving with excess alcohol or under the influence of drugs is not just a criminal offence but also completely unacceptable which puts lives at risk.
"We will continue in our efforts to change driver behaviour in order to make our roads safer."
