Officers have made 70 arrests as part of the Christmas Anti Drink and Drug Drive Campaign.
Since the start of the campaign on December 1, 43 drug drive and 27 drink drive arrests have been made across the region.
Flintshire see's the highest number of drug driving arrests in this period and Wrexham sees the highest number of drink driving arrests.
The highest reading provided so far has been 114 (the legal limit is 35) whereby a 40-year-old man from Betws-yn-Rhos, Conwy was arrested near Llanfair Talhaiarn shortly after 9pm on December 14 following a road traffic collision.

He has been charged with drink driving and will appear before Llandudno Magistrates Court on January 9.
Another high reading was provided when a 42-year-old woman from Ellesmere Port provided a roadside reading of 107 after being stopped by officers in Dobshill shortly after 6pm on December 14.
She was arrested on suspicion of drink driving, however she refused to provide a further sample of breath whilst in police custody so she has been charged with refusing to provide and will appear before Mold Magistrates Court on 5 January.
All those who were arrested on suspicion of drug driving now have an anxious wait for the results of further tests before a charging decision is made.

If convicted of drug driving they could face being disqualified, receive a fine, a prison sentence and a criminal record.
Few people also realise that a drug drive conviction also means greater insurance costs and the possibility of being unable to travel to countries such as the USA.
Sergeant Liam Morris of the Roads Policing Unit said: “Driving whilst under the influence is not only a criminal offence but it is also completely unacceptable and selfish act which puts lives of innocent road users at risk.
"The consequences are huge, not only does it risk death or serious injury but think about the potential loss of your career, home and family life.
“Despite our repeated warnings regarding the dangers of drink and drug driving, it is disappointing that people are still choosing to risk their own lives and the lives of other road users by taking to the roads whilst under the influence.
“Drugs affect your mind and body in a variety of ways that mean you can’t drive safely. When your ability to drive is impaired the chances of you being involved in a collision significantly increase.
"The effects can last for hours or even days. Driving while under the influence of drugs can lead to slower reaction times, poor concentration, confusion, fatigue, being over confident which means you take unnecessary risks and demonstrate erratic behaviour. All of which attract the attention of patrolling officers who are out looking for these behaviours.
“We are fully committed to help make the roads safer for all and will continue to target those who wilfully endanger their own lives and the lives of others. Please don’t think the rural nature of the region affords you protection because it does not.
Sgt Morris added: “This weekend and next will see many attend Christmas parties so we are pleading with everyone to make arrangements to get home safely, and to also remind everyone that they could still be over the alcohol limit the morning after a night of drinking.
“We want everyone to enjoy a safe and happy festive season and so this is one of our most important annual campaigns. Officers are out patrolling in marked and unmarked vehicles, as well as conducting roadside checks to ensure the roads are safe for all.”
