Medicinal cannabis and driving in the ACT: where the law stands
The ACT's position was restated plainly in 2026: it remains an offence to drive with cannabis in your system even if prescribed, and a medical prescription cannot be used as a defence. That answer came in the ACT Government's formal response to a community petition seeking reform for medicinal cannabis patients.
The Government grounded its position in its Vision Zero road safety policy, and parliamentary questions in 2025 raised whether the ACT should move closer to Victoria's discretion model — but no change has passed.
There's a particular ACT irony worth noting for readers: the ACT permits small-scale personal cannabis cultivation under territory law, yet remains strict on any detectable THC behind the wheel — prescription or not.
