As medicinal cannabis becomes a more common treatment for various health conditions, many Australian employers are finding themselves in uncharted territory. While it is a legal prescription medication, its use in a professional setting creates a unique set of challenges. This is particularly true for businesses operating in high-risk industries where safety is the top priority.
Managing medicinal cannabis requires a careful balance between an employee’s right to manage their health and the employer’s duty of care under Workplace Health and Safety (WHS) laws.
The Legal Landscape
In Australia, medicinal cannabis is treated similarly to other prescription medications that may cause impairment, such as strong painkillers or certain antidepressants. Employers generally cannot discriminate against an employee for using a prescribed medication to treat a disability or health condition.
However, this does not give an employee a “free pass” to work while impaired. Under WHS legislation, both the employer and the employee have a shared responsibility to ensure the workplace remains safe for everyone. If a medication affects a person’s ability to perform their job safely, the employer has the right to intervene.
High-Risk Environments and Impairment
The stakes are significantly higher in sectors such as construction, mining, transport and manufacturing. In these environments, being under the influence of a substance that affects coordination or reaction times can have devastating consequences.
A key challenge for HR managers is that standard drug testing often detects the presence of a substance rather than the level of actual impairment. Because medicinal cannabis can remain in a person’s system long after the therapeutic effects have worn off, a positive test result does not always mean a worker is unfit for duty. This makes clear communication and individual risk assessments essential.
Proactive Steps for Employers
To manage this evolving issue effectively, organisations should consider the following steps:
- Review Drug and Alcohol Policies: Ensure your policies are up to date and specifically address the use of prescription medications. Policies should focus on “fitness for work” rather than just the presence of a substance.
- Encourage Self-Disclosure: Create a culture where employees feel safe disclosing their use of prescription medications without fear of immediate termination. This allows for a proactive discussion about potential risks and necessary adjustments.
- Conduct Individual Assessments: If an employee in a safety-critical role is prescribed medicinal cannabis, work with medical professionals to assess whether they can continue their duties safely or if temporary redeployment is required.
Maintaining a Safe and Inclusive Workplace
Every business is different and there is no single rule that applies to every situation. The goal is to support employee wellbeing while maintaining a rigorous focus on safety. By having robust procedures in place, you can avoid the confusion and legal risks that often arise when these situations are handled on an ad hoc basis.
