The Canadian Trucking Alliance (CTA) is repeating its call for rules to guide random drug testing, following research that shows an increase in positive marijuana tests in U.S. jurisdictions that have legalized the drug.
Canadian legislation to legalize marijuana for recreational use is expected this summer.
Since 2016, the number of safety-sensitive workers who tested positive for marijuana increased 39% in Nevada, 20% in California, and 11% in Massachusetts, Quest Diagnostics found in a review of 10 million drug tests conducted in the U.S.
“These increases are similar to the increases we observed after recreational marijuana use statues were passed in Washington and Colorado,” said Barry Sample, senior director – science and technology.
“CTA has maintained that if risk is to be downloaded to employers as a result of legalization, then we need the necessary tools to help mitigate that risk,” says Jonathon Blackham, the alliance’s director of policy and public affairs.
