Misunderstandings about workplace drug and alcohol management are more common than many people realise. Even in safety‑critical industries, long‑standing myths continue to influence how employees think about impairment, testing, and fitness for work. These misconceptions can weaken safety culture, undermine compliance, and increase the likelihood of incidents.
That’s why our September edition of the Behind the Test newsletter focuses on one theme: debunking the myths that refuse to die.
This month, we unpack the beliefs that cause the most confusion — from how long alcohol and drugs stay in the body, to whether “quick fixes” can speed up sobriety, to surprising facts about alcohol that still catch people off guard.
For organisations committed to maintaining a safe, fit‑for‑work environment, understanding these myths is essential.
Why Myth‑Busting Matters
Clear, accurate information is one of the most powerful tools in workplace safety. When employees misunderstand impairment, testing processes, detection windows or workplace expectations, risk increases. These misunderstandings can affect:
- Safety outcomes
- Employee behaviour
- Policy compliance
- Trust in workplace systems
- The defensibility of testing programs
Debunking myths isn’t just an educational exercise — it’s a core safety strategy. It helps employees understand why drug and alcohol management exists and how it protects them, their colleagues, and the public.

The September newsletter breaks down the myths that matter most, including:
