State by state
How the rules differ in each Australian state and territory.
New South Wales
CBD (cannabidiol) is a prescription medicine in NSW as everywhere in Australia. What is different is a 2026 driving scheme that has passed but not started.
Victoria
CBD (cannabidiol) is prescription-only in Victoria. Since March 2025 a court can spare a prescribed patient's licence, but THC when driving is still an offence.
Queensland
CBD (cannabidiol) is prescription-only in Queensland and needs no state approval to prescribe. Drug-driving penalties for THC rise on 1 December 2026.
Western Australia
CBD (cannabidiol) is prescription-only in WA. THC when driving is an offence even if prescribed, and workplace testing matters for FIFO and mining workers.
South Australia
CBD (cannabidiol) is prescription-only in SA and needs no state approval to prescribe. Driving with THC is an offence with no medical defence.
Tasmania
CBD (cannabidiol) is prescription-only in Tasmania. It is the only state where THC taken as lawfully prescribed is not a drug-driving presence offence.
ACT
The ACT lets adults possess and grow small amounts of cannabis, but that does not make CBD oil legal to buy. Cannabidiol is still prescription-only.
Northern Territory
CBD (cannabidiol) is prescription-only in the NT, with no extra Territory prescribing rules. THC when driving is an offence with no medical defence.
