If workplace drug testing (WDT) is going to be done, it needs to be done right. Employers can’t afford to expose themselves to legal action over false results.

Workplace drug testing (WDT) in some sectors such as aviation, transport and mining has been going on for years, since the mid-1990s.

Surveys conducted across all Australian industries have found the proportion of the workforce using illicit drugs is highest in Hospitality, Construction, Retail and Transport.

Proponents of WDT argue that employers have a duty of care to provide a safe working environment, particularly in safety-critical professions. Approximately 11% of workplace injuries and 5% of workplace fatalities involve substance abusers.

Opponents say that it compromises privacy and isn’t 100% reliable - producing occasional false positives.

A new standard was introduced during 2010. This provides greater certainty and rigour - it reduces the likelihood of false negatives and positives, which is critically important if cases go to court.

The applicable Standards specify that onsite screening must be accredited. AS 4760, Appendix A (in On-site screening procedure A3.2 c) stipulates that: “the collecting agency shall be able to demonstrate that the collectors are proficient in the use of the device.”

NATA offers a one-day training course that gives participants an understanding of the legal framework and standards that apply to WDT.

It covers the management requirements of facilities and such important areas as how to evaluate potential external services and suppliers.

Accredited procedures stand up in court. Labs that are accredited limit their legal issues. For more information about how workplace drug testing training contact This e-mail address is being protected from spambots. You need JavaScript enabled to view it
