Workplace drug testing, such as pre-employment testing (required by the federal government for all DOT employees), reasonable suspicion or for-cause employee testing, and random testing, can help employers maintain a safe and healthy working environment. The use of drugs like amphetamines, opiates, barbiturates, cannabinoids, cocaine, benzodiazepine, and oxycodone all can have a negative impact on the workplace. Negative consequences of not identifying drug use problems can lead to serious workplace accidents, missed work, loss of production, theft, turnover, poor decision making, and lower co-worker morale – all impacting a company’s bottom line.
