Weyburn's police chief says there are likely benefits from controversial changes proposed for impaired driving laws.

The amendments to the federal criminal code would allow police to demand a breathalyzer sample, even without any other signs of impairment. For example, such demands could be made at a check stop. Under the current law, there must be other indicators, such as the smell of alcohol on someone's breath, for the officer to demand the test.

Police Chief Marlo Pritchard says this has been tried in other countries, with positive results. "It's been proven, from what I have read, that it has reduced fatalities in those countries that have adopted this model, up to 20, 25 per cent. It's a significant impact where people have a higher perception of being caught if they are impaired. So, there might be benefits."

"I don't know exactly what it's going to look like operationally." added Chief Pritchard. "But how I understand it, the threshold for demanding a breathalyzer or saliva test is lower, or is going to drop somewhat. If that saves some lives, I think everygbody is for it."

However, opponents to the changes argue that the new law could violate constitutional rights, including unlawful search and seizure.

The criminal code changes are part of the package of laws which will legalize marijuana next year.

They also include standards by which someone can be deemed impaired from smoking the drug. "Part of the issues, at least from a policing agency, is what training are we going to do for our members." Pritchard said. "What's the cost going to be to the police services. And the questions around that that I don't have answers for."

The legalization of marijuana will take effect on July 1st, 2018.
