I have to agree. The same goes for the military. They only test for it if there is a reason/provocation otherwise most companies and organizations just test for the standard NIDA 5.
1. Cannabinoids (marijuana, hashish - tests for metabolite THCCOOH)
2. Cocaine (cocaine, benzoylecognine, cocaethylene)- tests for cocaine metabolite)
3. Amphetamines (amphetamine, methamphetamine)
4. Opiates (heroin, opium, codeine, morphine, 6-MAM)
5. Phencyclidine (PCP)
