NSW Passes Medicinal Cannabis Driving Reform: What Patients Get
Registered patients who test positive for THC will face a 24-hour suspension and a lab test instead of an automatic charge. The scheme starts late 2026 or early 2027.
This story is about Australia — not the country you picked in the header.
Key takeaways
- The Road Transport Amendment (Medical Cannabis and Driving Offences) Bill 2026 passed NSW Parliament on September 17, 2026.
- Patients must register with Transport for NSW, show a valid prescription and complete an online course; learner, P-plate and commercial drivers are excluded.
- A positive roadside test means a 24-hour driving ban and a lab test; below 50 ng/ml there is no further action.
- First and second detections within two years bring warnings; a third brings a A$722 fine and at least three months' suspension.
- Impaired drivers still face drug-driving charges regardless of registration.
New South Wales is the latest Australian state, after Tasmania's defence and Victoria's 2025 change to licence penalties, to soften presence-based drug-driving rules for people prescribed medicinal cannabis. The Road Transport Legislation Amendment (Medical Cannabis and Driving Offences) Bill 2026 passed on September 17, and the Minns government announced it the next day.
Who will be able to drive on prescribed THC in NSW
Until now, a NSW patient who took prescribed cannabis as directed and was not impaired could still be charged for having THC in their saliva, because the offence is presence, not impairment. The reform keeps the roadside test but changes what follows it for registered patients.
How the scheme will work
- Register
With Transport for NSW, providing evidence of a valid prescription and completing a mandatory online education program. - Test positive at the roadside
The driver gets an immediate 24-hour driving ban, and the sample goes to a laboratory. - Lab result below 50 ng/ml THC
No further action. - Above the threshold
A warning for a first or second detection within two years; a third brings a A$722 fine and a minimum three-month licence suspension.
| Who | Covered? |
|---|---|
| NSW unrestricted licence holders with a valid prescription | Yes, once registered |
| Learner and P-plate drivers | No |
| Commercial drivers | No |
| Registered patients with alcohol or other drugs in their system | No |
| Anyone showing signs of impairment | No: charged with serious drug-driving offences |
Nobody should drive while impaired by cannabis, alcohol or any other drug. That is not changing.
Jenny Aitchison, NSW Minister for Roads and Regional Transport
How NSW compares
- Tasmania already has a statutory medical defence, applied strictly to lawfully prescribed and supplied cannabis.
- Victoria kept the offence but has let magistrates decide not to cancel a patient's licence since March 1, 2025, and is running a closed-track driving trial with Swinburne University.
- Other states and territories still treat detectable THC as an offence regardless of prescription.
Start date, conditions and what police will check
The government says implementation will take until late 2026 or early 2027 while Transport for NSW builds the registration system and course.

FAQ
When does the NSW medicinal cannabis driving law start?
It passed on September 17, 2026, and the NSW Government expects implementation in late 2026 or early 2027, once Transport for NSW has built the registration system. Until then the existing law applies.
Who can register under the NSW scheme?
NSW unrestricted licence holders with a valid medicinal cannabis prescription who complete a mandatory online education program. Learner, P-plate and commercial drivers are excluded.
What happens if a registered patient tests positive?
They get an immediate 24-hour driving ban and the sample goes to a lab. Below 50 ng/ml there is no further action; above it, the first two detections within two years bring warnings and the third a A$722 fine and at least three months' suspension.
Can a registered patient drive while impaired?
No. Drivers who show signs of impairment face serious drug-driving charges regardless of registration.
