Canada’s roadside drug detection gear has a drug problem

Concerns raised about first device set to be approved for roadside drug detection

OTTAWA – The first device set to be approved by the federal government for roadside saliva tests to determine marijuana impairment isn’t suited for cold weather, and has been found to give “fairly large proportions of false-positive or false-negative results.”

Last month Justice Minister Jody Wilson-Raybould published a notice of intention to approve the Dräger DrugTest 5000, and list it as “approved drug screening equipment” for law enforcement to use at the roadside to test for both THC and cocaine.
