Halifax Regional Police are still undecided as to whether they will implement a federally approved roadside test for cannabis.

The Drager DrugTest 5000 was recently approved by the federal government for roadside testing of THC, the primary psychoactive ingredient in cannabis.

Vancouver's police department announced it will not use the test come Oct. 17, and will instead continue to use standardized field sobriety tests.

Const. John MacLeod said Halifax police will follow suit for the time being.

"We have other tools available that we've had for quite a long time for officers to deal with impaired driving by drugs, both the standardized field sobriety testing or the drug recognition evaluations," said MacLeod.

There has been widespread concern over how a test of THC levels will work, given the chemical can remain in a person's system for days after the effects of cannabis have worn off.



MacLeod said there is one test approved at this time and more are expected to follow.
