What is a Drug-free workplace?

Updated 20 Jan 2026 5 min read

A drug-free workplace is one where the use of alcohol and drugs that could impair safety or performance is prohibited during work hours. In Australia, employers have WHS obligations to manage risks from impairment, and many industries require drug and alcohol testing. However, policies must be reasonable, non-discriminatory, and respect employee privacy while meeting safety obligations.

Understanding drug-free workplaces

Drug and alcohol policies balance WHS obligations to maintain a safe workplace with employee rights to privacy and fair treatment. Policies must be reasonable, proportionate to risk, and properly implemented.

Safety rationale

  • WHS duty of care
  • Risk to self and others
  • Safety-critical tasks
  • Regulatory requirements

Policy requirements

  • Clear and reasonable rules
  • Properly communicated
  • Consistently enforced
  • Privacy compliant

Drug and alcohol policies operate within several legal frameworks:

Applicable laws

WHS laws: Duty to manage impairment risks
Fair Work Act: Unfair dismissal protections
Privacy laws: Handling of test results
Discrimination laws: Disability and addiction

Types of testing

Different types of drug and alcohol testing may be used:

  • Pre-employment: Before starting work (common in safety-critical roles)
  • Random testing: Unannounced testing of employees selected at random
  • For-cause testing: When there is reasonable suspicion of impairment
  • Post-incident testing: Following workplace accidents or near-misses
  • Return-to-work testing: After rehabilitation or breach of policy
  • Blanket testing: Testing all employees at a site or time

Reasonableness requirement

Drug and alcohol testing must be reasonable given the workplace and role. The Fair Work Commission has found testing unreasonable where it was not justified by safety requirements or was implemented without proper consultation and policy.

Implementing effective policies

Policy elements

  • Clear scope and prohibited conduct
  • Testing procedures and triggers
  • Consequences of positive tests
  • Employee assistance programs

Fair implementation

  • Consult with employees/unions
  • Communicate policy clearly
  • Use accredited testing providers
  • Apply consistently to all

Common drug policy mistakes

Automatic dismissal

Having a "zero tolerance" policy that mandates dismissal without considering circumstances, which may be found to be unfair.

Testing without policy

Implementing drug testing without a clear, communicated policy or without contractual basis for testing.

No support options

Failing to offer employee assistance programs or rehabilitation pathways for employees with substance issues.

Key takeaways

Drug-free workplace policies must balance WHS obligations with employee rights. Policies should be reasonable, clearly communicated, consistently applied, and include support options alongside consequences.
