A non-negative drug test result can be a turning point — not just for the employee, but for the entire workplace. While it may signal a breach of policy, it can also be a sign that someone needs support. And how employers respond matters more than ever.
Workplace drug testing should never be about punishment alone. It’s about fostering a culture of safety, accountability, and early intervention — and supporting those who may be struggling behind the scenes.
What does a non-negative drug test mean?
Most initial workplace drug tests — like saliva-based screening kits — provide an indicative result only. A non-negative result doesn’t automatically confirm drug use or impairment.
To confirm the result, a laboratory test using gas chromatography-mass spectrometry (GC-MS) or an equivalent method must follow. Employers should never act on a non-negative result alone without waiting for a lab-confirmed outcome.
Stay calm, consistent, and compliant
If an employee returns a non-negative result, respond with professionalism and consistency:
- Keep it private: Notify the employee discreetly and avoid speculation
- Follow your policy: Only proceed as outlined in your workplace drug and alcohol policy
- Pause any action: Don’t impose disciplinary measures until the result is formally confirmed
If you don’t have a policy in place yet, now’s the time to develop one. Here’s a practical guide:

Support comes first
Behind every drug test result is a person — and sometimes, a deeper issue. If an employee is struggling with drug use, a supportive workplace response can help them get back on track.
Here’s how employers can help:
- Provide access to support: Refer employees to an Employee Assistance Program (EAP) or suggest local addiction services
- Offer open conversations: Encourage honest dialogue without judgment
- Reinforce confidentiality: Ensure the situation is handled with discretion to protect the individual’s dignity
Use the right test at the right time
Saliva drug tests like the DrugSense DSO8+ are ideal for quick screening in the workplace — such as random testing or reasonable suspicion scenarios. They're easy to use, fast, and compliant with AS/NZS 4760:2019.
But remember: screening is just the first step. Any non-negative result should be sent for lab confirmation before action is taken.
Plan the way forward — not the way out
If a confirmed positive result comes back, consider:
- Temporary reassignment or leave (especially in safety-critical roles)
- Return-to-work agreements with clear conditions
- Support programs to address the root causes of use
Discipline may still be necessary in some cases, but combining it with compassion shows your commitment to employee wellbeing.
Final thoughts: A result is a moment — not a label
A non-negative drug test result isn’t the end of the line. When handled properly, it’s a chance to protect your workplace, show leadership, and potentially change a life.
Supporting employees through this process reinforces a culture of safety, respect, and trust — the kind of culture where people perform better, stay longer, and feel like they matter.
