How can employers manage drug testing and medical cannabis in the workplace?
As medicinal cannabis use rises in Australia, employers are encountering new challenges in balancing workplace safety, legal compliance, and employee rights.
Pre-employment and random drug testing
Employers can conduct drug testing, but it must be justified, particularly in high-risk industries like construction or transport. It’s important to note that while drug tests may flag cannabis use, employers should be cautious about termination decisions. A positive test result doesn’t necessarily equate to immediate dismissal, especially for employees using cannabis under medical supervision. The Fair Work Act protects employees from unfair dismissal, so employers need a sound, legally defensible reason for any action.
Medicinal cannabis: health and safety implications
The use of medical cannabis, especially in safety-sensitive roles, poses significant challenges for employers. Jobs that involve driving, operating machinery, or working at heights require a clear understanding of how cannabis affects performance. While an employee may have a legal prescription, employers still have a duty under health and safety legislation to ensure that workers are fit to perform their roles without endangering themselves or others. This means gathering more medical information, conducting a risk assessment, and potentially reallocating duties or suspending employees from safety-critical tasks.
If a safety incident occurs involving an employee with a medicinal cannabis prescription, safety regulators will want to know whether the employer was aware of the risk, whether they conducted a risk assessment, and what control measures were implemented (e.g., drug testing or reassigning duties). This is crucial to limiting the employer’s liability.
Driving under the influence
Another major concern is driving while THC, the psychoactive ingredient in cannabis, is still in the system. Regardless of whether it’s medically prescribed, driving with THC present is illegal in most Australian states and territories. Employers must be mindful of their responsibility if employees need to drive as part of their job, as they could be held liable if an incident occurs while THC is in the employee’s system.
Discrimination and legal compliance
Employees prescribed medicinal cannabis are protected from discrimination, but this doesn’t mean employers have no options. Employers can request further medical information to ensure the employee can safely perform their job. If safety cannot be guaranteed, employers may consider making reasonable adjustments, such as reallocating duties or temporarily placing the employee on leave while more information is gathered.
However, any decision that could be seen as unfavourable toward the employee, such as dismissal or reducing hours, needs to be carefully managed. Employers must ensure their actions are justified and related to safety, not merely the employee’s medical condition, to avoid discrimination claims. Consultation with legal experts is essential before making decisions with potential legal repercussions.
Privacy considerations
Under the Privacy Act, medical information, including cannabis prescriptions, is considered sensitive information. Employers must handle this data in accordance with privacy laws and ensure it is only used to determine whether an employee can safely perform their role.
Managing the situation
To minimise risk, employers should:
- Create clear drug policies – Ensure employees are aware of the rules regarding drug use and the process for testing and handling positive results.
- Require disclosure of prescription medications – Employees must inform employers if they are taking medication, including cannabis, that could affect their work.
- Conduct risk assessments – Evaluate the risks to safety posed by cannabis use and take appropriate measures, such as drug testing or task reassignment.
- Seek legal advice – Before taking disciplinary action, particularly if it involves medically prescribed cannabis, employers should consult legal experts to avoid claims of unfair dismissal or discrimination.
By taking these steps, employers can effectively manage the balance between ensuring workplace safety and protecting employee rights. As medicinal cannabis becomes more common, it’s crucial to have a sound, legally compliant approach in place to address these challenges.
