Statistics indicate that about 70% of illegal drug users are employed. These same individuals are at risk for on-the-job accidents, increased absenteeism, high usage of medical care and emergency room services, as well as being more likely to negatively affect productivity, morale, and the company's bottom line. More and more employers are turning to drug testing as a means of creating a safer workplace, however, federal mandates also require evaluation by a Substance Abuse Professional in certain situations and industries. (e.g., U.S. Department of Transporation and Nuclear Regulatory Agency).
