Marijuana most common cause of impairment in TTC tests

The head of the TTC, Andy Byford, has issued his omnibus report on operations at the transit agency. It includes numbers showing that marijuana was the drug of choice among those randomly tested in recent months. The numbers are below. The tests were performed on 1,174 employees arbitrarily and found that 23 people, or about two per cent, were not compliant with the TTC policy. Sixteen tested positive for drugs, five tested positive for alcohol and two refused to take the test with whatever consequences flowed from that. .
