NSW Medicinal Cannabis Driving Reforms—What You Need to Know

New South Wales has just passed significant reforms to its drug-driving laws, changing how eligible medicinal cannabis patients who test positive for THC are treated when driving — with the changes designed to distinguish between the presence of THC and driving while impaired, while maintaining road-safety protections.

What Is Changing?

Under the new framework, eligible medicinal cannabis patients will no longer automatically face a drug-driving penalty solely because THC is detected in their system, provided they are registered under the scheme, meet the required conditions and are not impaired. (NSW Government)

To access the new protections, patients will need to:

• hold a valid medicinal cannabis prescription;

• register with Transport for NSW;

• complete a mandatory online cannabis and driving-safety education program; and

• hold an unrestricted NSW driver licence.

Registered patients must also have no alcohol or other drugs present within their system. It is also important to note, that learner and provisional licence holders and commercial drivers will not be eligible for the scheme. (NSW Government)

What Happens If You Test Positive for THC?

Roadside drug testing is not going away. However, under this reform change if a registered medicinal cannabis patient returns a positive roadside THC test, they will still receive an immediate 24-hour driving ban while their sample is sent for laboratory testing.

What happens next depends on the laboratory result:

• THC below 50 ng/mL:
  No further action will be taken.

• THC at or above 50 ng/mL:
  The first and second detections within a two-year period will result in a warning.

• Third detection within two years:
  A $722 fine and a minimum three-month licence suspension will apply. (NSW Government)

What Isn’t Changing?

A registered medicinal cannabis patient who shows signs of impairment can still face serious driving-under-the-influence charges, as the reforms do not provide permission to drive while impaired. Standard drug-driving rules will also continue to apply where other drugs are detected, and registered patients will remain subject to blood and urine testing following serious crashes. (NSW Government)

When Will The Changes Begin?

Perhaps the most important thing for patients in New South Wales to know is that although the legislation has now passed NSW Parliament, the new system is not yet operational. Transport for NSW is developing the patient registry and mandatory education program, with implementation expected in late 2026 to early 2027, where the scheme will then be reviewed after its first 12 months of operation.

The Key Takeaway

The NSW reforms represent a significant change from a system based primarily on the presence of THC for eligible medicinal cannabis patients. Once implemented, eligible registered patients who are not impaired will have a pathway that does not automatically result in a drug-driving penalty simply because THC is detected. However, roadside testing, the immediate 24-hour driving prohibition following a positive test, eligibility requirements and penalties for impaired driving will remain.

For patients prescribed medicinal cannabis in NSW, the distinction is important: the reforms change how THC presence is treated in certain circumstances — they do not change the obligation to be fit to drive.
