Drug testing in the workplace

The majority of workplace drug tests are undertaken on samples of urine, oral fluid, hair, sweat or blood. Each sampling media has its advantages and disadvantages. In addition, there are various sample collection devices available and options to undertake your own sample collections or to contract an agency to collect on your behalf.

Drug testing in the workplace should be:

  • Accurate - The process should not falsely accuse innocent people or return negative results for staff who should actually return positive results. For this reason screening results must not be interpreted as a final result - A laboratory result is the most important result in the testing process.
  • Tried and tested – it is important that the chosen testing method is an accepted and reliable method of testing. To this end the testing process needs to be sound and should be capable of being supported by experts in the field.
  • Operationally Efficient – the testing program must be fast (in order to ensure that staff can complete the testing program quickly).
  • Private - the testing program should have clear systems and procedures in place designed to protect individual privacy.

Drug testing in the workplace can be a source of controversy, anxiety and concern among employers and employees.  It is imperative that drug testing in the workplace is only introduced where necessary and in conjunction with a substance misuse policy. Organisations should be aware of their legal duties with regard to health and safety legislation and respect other legislation, such as the Human Rights Act 1998, which restrict the scope of testing in the workplace.
