The Canadian version of QuickFix passes these tests.
If the job entails working with equipment or other hazardous jobs they fall under the dominion of the DOT federal protocols. For any of those tests synthetic works fine. And for most others it works fine. The problem is with some drug testing facilities are offering the added test to see if its fake or not. The Canadian version of QuickFix is supposed to even pass those.
Mine are always DOT type tests so I don't bother with the canadian version.
