Victoria's closed-track driving trial: recruitment complete, results due mid-2026
Victoria's closed-circuit track trial — run by Swinburne University to evaluate how prescribed THC medication affects patients' real driving performance — has completed recruitment of patient participants, with control-group testing underway as of April 2026.
The Government has said results are expected mid-2026, and that it will then consider broader reform that would treat medicinal cannabis like other prescription medication.
What already changed in Victoria: since 1 March 2025, magistrates have discretion not to cancel the licence of a driver who tests positive for THC, held a valid prescription, and was not impaired. The offence and fine still stand — the discretion is about the licence only.
What hasn't changed: driving with any detectable THC remains an offence in Victoria, prescription or not. The trial is the evidence base for what comes next, not a change in the law.
When the results land, this tracker and the fortnightly newsletter will cover what they say and what the Government does with them.
