As the use of medicinal cannabis becomes more common across Australia, employers are increasingly facing complex challenges related to safety, compliance and employee wellbeing. At the forefront of helping businesses navigate this evolving issue is Integrity Sampling, Australia’s leading provider of workplace drug testing and drug and alcohol management services.
With a national footprint and over two decades of experience, Integrity Sampling is urging businesses to adopt proactive strategies for managing medicinal cannabis in the workplace. The company offers expert advice, policy development, testing services and education to help employers meet their legal obligations and maintain safe working environments.
“Just because a substance is legally prescribed doesn’t mean it’s automatically safe in a workplace,” says Michael Wheeldon, Director of Integrity Sampling. “Medicinal cannabis, particularly when it contains THC, can impact alertness, coordination and reaction time – factors that are critical in high-risk industries like construction, mining and transportation.”
Integrity Sampling is working closely with organisations to address common misconceptions about prescribed medications. One such myth is that a medical prescription overrides workplace drug and alcohol policies. In reality, all workers must be fit for duty regardless of whether the substance is prescribed or purchased over the counter.
At the same time, employers are legally required under workplace health and safety laws to identify and manage any risks related to drug use — even when that drug is medicinal cannabis.
To support employers, Integrity Sampling emphasises the need for robust, clearly worded drug and alcohol policies. These policies must outline expectations around fitness for duty and provide a framework for employees to disclose prescribed medications that may impact safety.
“Policy alone isn’t enough,” says Wheeldon. “Education is equally vital. Our workplace education sessions help employees understand their responsibilities and the potential impact of prescribed substances on job performance.”
Integrity Sampling also provides advanced drug testing services that can detect THC, the psychoactive component in many medicinal cannabis products. While detection doesn’t automatically equate to impairment, it reinforces the importance of disclosure. Without it, employers may lack the context to make safe and legally sound decisions.
“We advise employees using medicinal cannabis to speak with their employers before any issues arise,” says Wheeldon. “And we help employers handle those disclosures sensitively and confidentially.”
With laws, testing technologies, and public attitudes continuing to shift, Integrity Sampling remains a trusted partner for businesses seeking clarity, compliance and safety in the face of change.
Integrity Sampling recommends five key actions for employers:
• Review and update drug and alcohol policies to reflect the realities of prescribed medications.
• Provide regular employee education and training.
• Conduct consistent and fair drug testing.
• Encourage open disclosure of medications that may impact safety.
• Seek expert guidance to develop appropriate systems and processes.
“Medicinal cannabis in the workplace isn’t a black-and-white issue,” concludes Wheeldon. “It requires a balanced, informed approach that prioritises safety, legal compliance, and respect for individual health needs. Integrity Sampling is here to help every step of the way.”
