Drug Testing Facts

Drug testing is the evaluation of a urine, saliva, hair, blood or other type of biological sample to determine if the subject has been using the drug or drugs in question. There are many circumstances that may lead to drug testing:

  • Pre-employment drug screening test or random, work-related drug testing to identify on-the-job drug abuse.
  • College or professional athletic drug testing.
  • Post-accident vehicular or job related drug testing which may have involved human error resulting in casualties or property damage.
  • Safety-related drug testing - if an employee's job could lead to safety issues if judgement or physical ability were impaired.

Drug testing is often done when applying for employment, especially for positions that may involve federal transportation, airline industries, railways, hospitals, and other workplaces where public safety is of the utmost importance. However, workplace drug testing is now common in general for many U.S. employers to lessen the impact from drug abuse, safety concerns, and low productivity in the workplace.
