With marijuana fully legalized nationwide, one of the biggest issues and concerns that has been mentioned in the past months is how police will patrol the roads.

A device recently approved by the federal government, the Draeger DrugTest 5000, is produced by a company based in Germany, and Moose Jaw Police Chief Rick Bourassa says the Moose Jaw Police Department has been in talks with the federal government about receiving some.

"We have been in discussions for a while across the province with the police services and our ministry of corrections and policing and yes we have been in discussion about the roadside screening devices. There has been funding made available for the purchase of those. We are working with the ministry now on having those obtained and deployed across the province."

Although the Moose Jaw Police will only be receiving one, Chief Bourassa says they have other means to catch high drivers.

"There are two components to that; there's the standardized field sobriety testing which most members are familiar with, and it's basically a roadside observational and physical test. There is another process that is testing done by what we call the 'drug recognition expert,' who is able to do some of those tests."

Chief Bourassa goes on to say that when it comes to knowing if you're too impaired to drive, use common sense.

"It is very much a self-monitoring system, much like it is with alcohol. There's no real clear line on how much would lead to impairment. Different people would be impaired using different amounts of alcohol - depending on a lot of biological factors. The same would apply to cannabis. The best way to avoid being impaired is if you're using any sort of substance at all then don't drive afterward."

Police across the country will be out in numbers watching for impaired drivers.

Officials are also reminding users that there are rules for consuming cannabis and it's not a free for all. You cannot consume in public and can only possess 30 grams of dried cannabis. A pamphlet was mailed out earlier this month to serve as a reminder of what is and isn't allowed or you can click here for a quick link from the provincial government.
