Prescribed medicinal cannabis? Know exactly where you stand before you drive.
Australia's independent guide to medicinal cannabis and driving law — every state and territory, in plain English, checked against the legislation.
Check your state in 10 seconds →Legal medicine, illegal chemistry: the drug-driving gap
More than a million Australians hold a medicinal cannabis prescription, but in most states drug-driving law still tests chemistry, not impairment: any detectable THC in a roadside saliva test is an offence, prescription or not. Tasmania has a medical defence, Victoria gives courts discretion over your licence, and NSW has a registration scheme before Parliament — everywhere else the rule is simple and harsh.
Start with the 10-second state check, compare drug-driving penalties by state, learn how mobile drug testing (MDT) works, or get the honest answer on how long THC stays detectable in saliva.
