Driving high has always been against the law and nothing changes now that recreational marijuana is legal.
The OPP say it is going to buy federally approved roadside drug-screening equipment to identify impaired drivers.
How many or when remains an unanswered question.
Until that happens, Sgt Jason Folz of Central Region says right now the determination of impaired driving by drug will be done by a drug recognition expert and through a standard field sobriety test.
The federal government has approved the use of the Drager DrugTest 5000, which tests saliva for cocaine and THC.
This is the device to be purchased by provincial police, at a cost of $5,000 each.
If an officer suspects a driver has drugs in his or her body, the officer would stop the driver and ask him or her to provide a saliva sample, using a cassette.
The cassette is inserted into the analyzer to be tested and based on the result, the officer will decide whether to request that the driver go into a station for a blood test.
Folz says it goes without saying that provincial police will continue to talk to young people about the use and abuse of marijuana and marijuana products.
He admits there are a lot of questions to be answered including the sale of cannabis through retail outlets.
Folz says they will continue to enforce the laws as they come into play.
