The New South Wales Government has announced plans for significant reforms to the state's drug-driving laws that could allow eligible medicinal cannabis patients to drive legally without facing automatic licence suspensions for the presence of THC in their system.

The proposal, unveiled by Chris Minns and the Minns Government, seeks to address growing concerns that existing laws unfairly penalise people who are legally prescribed medicinal cannabis for legitimate health conditions. The reforms are expected to be introduced to Parliament through new legislation in the coming months.

Under current NSW laws, motorists can face penalties if roadside drug tests detect THC, the psychoactive component of cannabis, regardless of whether they are impaired at the time of driving. Critics argue that THC can remain detectable in saliva and other bodily samples long after any impairing effects have worn off, creating challenges for medicinal cannabis patients who rely on prescribed treatment.

The proposed legislation would establish a new framework allowing fully licensed drivers with registered medicinal cannabis prescriptions to continue driving, provided their THC levels remain below a prescribed threshold. Drivers would be required to register their prescription details with Transport for NSW to be eligible under the scheme.

If a roadside drug test detects THC, drivers would still be subject to an immediate 24-hour driving prohibition while laboratory analysis is conducted. However, rather than facing automatic penalties, the final outcome would depend on the concentration of THC identified through laboratory testing.

According to the proposed model, motorists whose THC levels exceed the permitted threshold would receive warnings for the first and second incidents within a two-year period. A third breach during that timeframe would trigger a minimum three-month licence suspension and a fine of approximately $704.

Government figures indicate that around one million Australians currently use medicinal cannabis, with up to one-third residing in New South Wales. Supporters of the reforms argue that many patients have been forced to choose between managing serious medical conditions and maintaining their ability to drive.

Advocacy groups welcomed the announcement, describing it as a practical update to laws that have struggled to keep pace with developments in modern medicine. Medical and research experts have also pointed to studies suggesting that THC may remain detectable for extended periods even after impairment has ceased.

The reforms have received support from several politicians, including Alex Greenwich and regional independent MP Roy Butler, who argue the changes better reflect contemporary medical practice while maintaining road safety protections.

However, the proposal has also attracted criticism. Opposition Leader Kellie Sloane questioned whether sufficient scientific evidence exists to establish an appropriate THC threshold and warned against implementing changes before certainty is achieved regarding impairment levels.

The debate reflects a broader national discussion about balancing road safety with the rights of medicinal cannabis patients. Several Australian jurisdictions have faced increasing pressure to review laws that focus on the presence of THC rather than actual driver impairment.

If passed, the legislation would represent one of the most significant changes to NSW drug-driving laws in recent years. The government says the reforms are designed to provide a fairer and more practical approach for medicinal cannabis users while maintaining strong safeguards to protect all road users.

The proposed legislation will now be subject to parliamentary scrutiny and debate before any changes take effevt.
