Drug Testing

Drug testing & Alcohol testing at work place

Alcohol and drug abuse creates significant safety and health hazards and can result in decreased productivity and poor employee morale.

It also can lead to additional costs in the form of health care claims, especially short-term disability claims.

The most common method of drug testing, urinalysis, can be done at the workplace (at a health unit, for example), a doctor’s office or any other site selected by the employer. An employee or applicant provides a sample to be tested. Usually precautions are taken, such as putting blue dye in the toilet and turning off the water supply, to prevent adulteration or substitution of specimens so that collection can be completed in privacy without any direct visual observation by another person.

What are the most common methods of drug testing?

Urine: Results of a urine test show the presence or absence of drug metabolites in a person’s urine. Metabolites are drug residues that remain in the body for some time after the effects of a drug have worn off. It is important to note that a positive urine test does not necessarily mean a person was under the influence of drugs at the time of the test. Rather, it detects and measures use of a particular drug within the previous few days and has become the defacto evidence of current use.

Breath: A breath-alcohol test is the most common test for finding out how much alcohol is currently in the blood. The person being tested blows into a breath-alcohol device, and the results are given as a number, known as the Blood Alcohol Concentration (BAC), which shows the level of alcohol in the blood at the time the test was taken.

Blood: A blood test measures the actual amount of alcohol or other drugs in the blood at the time of the test. Blood samples provide an accurate measure of the physiologically active drug present in a person at the time the sample is drawn.

Hair: Analysis of hair provides a much longer “testing window,” giving a more complete drug-use history going back as far as 90 days. Like urine testing, hair testing does not provide evidence of current impairment, but rather only past use of a specific drug.

Oral Fluids: Saliva, or oral fluids, collected from the mouth also can be used to detect traces of drugs and alcohol.

Sweat: Another type of drug test consists of a skin patch that measures drugs in sweat. The patch, which looks like a large adhesive bandage, is applied to the skin and worn for some length of time.

Common reasons employers implement drug testing are to:

  • Deter employees from abusing alcohol and drugs
  • Prevent hiring individuals who use illegal drugs
  • Be able to identify early and appropriately refer employees who have drug and/or alcohol problems
  • Provide a safe workplace for employees
  • Protect the general public and instill consumer confidence that employees are working safely
  • Comply with State laws or Federal regulations
