New South Wales has passed reforms allowing eligible medicinal cannabis patients to drive if their THC level is below 50ng/mL and they meet registration and safety requirements. The changes, which still require assent from the NSW Governor, aim to make drug-driving laws fairer for around 300,000 medicinal cannabis users while retaining safeguards against impaired or unsafe driving.

Drivers must hold an unrestricted NSW licence, register with Transport for NSW, provide proof of their prescription and complete an online safety course. A positive roadside test will still bring a 24-hour driving ban while samples are analysed; registered patients below the threshold face no further action if no alcohol or other illicit drug is detected, while three higher readings within two years can lead to a $704 fine and at least a three-month suspension. Victoria is testing similar approaches, whereas Queensland continues to enforce zero tolerance for THC and is introducing tougher penalties.
