An increasing number of employers are instituting drug testing programs.
Employers are concerned with the impact of drug use on safety, health and productivity.
Drug testing is becoming an integral part of the employment process, and it's important for job applicants to know what to expect. Drug testing usually occurs during the pre-employment physical. This is normally given after you have accepted the offer, but before you begin working. Receiving a negative result, indicating an absence of drug use, may be a stipulation for employment. A positive result may be grounds for withdrawing the offer.
