NSW passes medical cannabis driving reform, but start date is not yet set

NSW Parliament passed a bill on 17 September 2026 creating a voluntary registration scheme for drivers prescribed THC medicines. It has not commenced, and today any THC while driving remains an offence.

Transport for NSW says the Road Transport Legislation Amendment (Medical Cannabis and Driving Offences) Bill 2026 was passed on 17 September 2026 but has not commenced. Transport for NSW and NSW Police systems must change first. Commencement is "anticipated in late 2026 / early 2027", and no date is given.

Registered drivers would be exempt from the THC presence offence. Registration is voluntary and needs an unrestricted NSW licence, a valid prescription and an online education program. The exemption excludes learner, provisional and interlock licence holders, bus, taxi and rideshare drivers, certain heavy or dangerous goods vehicles and driving instructors. It does not apply if alcohol or other illicit drugs are also present.

Above a defined THC amount, a new registered-user offence applies. The first and second detections bring a warning letter only. A third within two years is an offence, with penalties including loss of licence. Roadside testing, the 24-hour ban, post-crash testing in fatal crashes and impairment charges are unchanged. Authorised prescribers must tell Transport when they prescribe THC medicine, via HealthLink or a paper form still being developed.

What changes in the law we track

Three NSW rules are affected, for patients and prescribers, but none has changed yet.

  • Driving offences: any THC while driving is an offence today, including for patients. The registration scheme is pending, with no start date.
  • Prescribing: Schedule 8 and Commonwealth pathway rules stand. The duty to notify Transport is pending, with no start date.
  • Timeline: the NSW key-changes record is updated to show the scheme as passed, not in force.

What this means

Until commencement, registration protects no one: the NSW Government lists a $722 penalty notice and 3-month suspension for a first offence.

Thresholds sit between comparators

The Bill as passed sets 50 ng/mL in oral fluid or 3.5 ng/mL in blood. For comparison, the UK limit is 2 µg/L (equal to 2 ng/mL) and Washington's is 5.00 ng/mL. Tasmania gives a full presence defence for medicine obtained under its Poisons Act.

Practice points

  • Clinics: registration needs a valid prescription at application and renewal, so continuity of prescribing affects a patient's protection.
  • Employers and patients in excluded roles: the exemption does not reach them.

This is information, not legal, tax or financial advice.

Limits

  • No commencement date has been published.
  • Fees, the HealthLink process, the paper form and the education program content are not yet published.
  • The Transport page gives no THC thresholds.
