NSW Medicinal Cannabis Driving Reforms Pass Parliament: What Happens Next?
When we wrote about NSW's proposed medicinal cannabis driving reforms in June, there was one point we kept coming back to: the changes had been announced, but they were not yet law.
There has now been a major update. On 17 September 2026, the Road Transport Legislation Amendment (Medical Cannabis and Driving Offences) Bill 2026 passed the NSW Parliament.
What Parliament has passed
- A new registration system for eligible medicinal cannabis patients. Drivers will need an unrestricted NSW licence, a valid prescription, registration with Transport for NSW and completion of the required cannabis-and-driving education program.
- Roadside drug testing will continue. There will be no change to the roadside testing process or roadside THC detection threshold.
- A positive roadside THC result will still mean an immediate 24-hour prohibition from driving while the sample is sent for laboratory testing.
- The laboratory maximum THC concentration will be 50 ng/mL in oral fluid and 3.5 ng/mL in blood.
- If an eligible registered patient's laboratory result is below the applicable maximum THC concentration, the usual drug-presence offence will not apply, provided the other conditions of the scheme are met.
- The first and second qualifying detections at or above the threshold within two years can result in formal warnings rather than an immediate charge, subject to the driver's eligibility and offence history.
- A further qualifying detection can result in penalties, including a fine and licence suspension.
- The scheme does not apply in the same way where alcohol or another prescribed illicit drug is detected, and it does not apply to learner or provisional drivers or specified commercial and special-category drivers.
- Driving while impaired remains an offence. A prescription and registration do not provide permission to drive while affected by cannabis.
A step forward — but roadside testing still isn't an impairment test
From our perspective at Made In Hemp, this is a welcome step in the right direction. It begins to recognise an important distinction between a patient lawfully using prescribed medicinal cannabis and someone who is actually impaired behind the wheel.
But there is still an important limitation.
If a registered patient returns a positive roadside result for THC, they will still receive an immediate 24-hour prohibition from driving while their sample is sent for laboratory analysis.
That means the immediate roadside response is still triggered by THC detection rather than by a roadside assessment that proves the driver is impaired. The laboratory threshold only becomes relevant afterwards.
The NSW Government describes the continued roadside testing process as an important road-safety safeguard. We understand the need to protect every road user.
At the same time, we would love to see the science and technology eventually reach a point where authorities can reliably test actual driving impairment, rather than having to rely primarily on the presence or concentration of THC.
That is not a simple problem. Australian fitness-to-drive guidance notes that the effects of THC are highly individual, and that cannabinoid pharmacokinetics make the severity and duration of impairment difficult to predict. So a THC number should not be read as a simple cannabis equivalent of a blood alcohol reading.
So what actually changes for medicinal cannabis patients?
Under the current NSW drug-presence framework, THC detected in a driver's system can result in an offence regardless of whether it came from lawfully prescribed medicinal cannabis.
The new scheme creates a separate pathway for eligible patients who register with Transport for NSW.
To participate, a driver will need to:
- hold an unrestricted NSW driver licence;
- be registered with Transport for NSW as a medicinal cannabis user;
- provide evidence of a valid prescription;
- complete the prescribed cannabis-and-driving education program; and
- continue to meet the other eligibility requirements of the scheme.
This is therefore not an automatic exemption simply because someone has a medicinal cannabis prescription.
We now know the THC thresholds
The legislation sets specific maximum THC concentrations for registered medicinal cannabis users.
If an eligible registered patient has THC below the relevant maximum concentration and satisfies the other conditions, the ordinary drug-presence offence will not apply.
Those conditions include having no other prescribed illicit drug detected and no alcohol detected.
Roadside drug testing is staying
This is probably the most important practical point for patients to understand.
The reforms do not mean a registered medicinal cannabis patient who tests positive at the roadside will simply be waved through.
Police roadside drug testing will continue.
A registered patient who returns a positive roadside THC test will still receive an immediate 24-hour prohibition from driving while their sample is sent for laboratory analysis.
The difference comes after that laboratory testing.
If the laboratory concentration is below the maximum threshold and all other requirements are satisfied, no further action will be taken under the ordinary THC-presence offence.
What if the laboratory result is above the threshold?
The legislation retains the warning system proposed when the reforms were first announced.
For an eligible registered medicinal cannabis patient, a first or second qualifying detection at or above the maximum THC concentration within two years can result in a formal warning instead of an immediate charge.
A further qualifying detection can then move into offence and penalty territory. The NSW Government says a third detection within two years can result in a $722 fine and a minimum three-month licence suspension.
So the new system is not simply a rule that says anything under a certain THC number is acceptable. It is a specific framework for registered medicinal cannabis patients, with eligibility requirements, testing, laboratory thresholds, warnings and escalating consequences.
Driving while impaired is still an offence
Nothing in these reforms gives someone permission to drive while affected by medicinal cannabis.
A medicinal cannabis prescription does not protect a driver who is actually impaired. Drivers showing signs of impairment can still face driving-under-the-influence offences.
The registered-user scheme also does not provide the same protections where alcohol or other prescribed illicit drugs are detected, and post-crash blood and urine testing following serious crashes will continue.
The distinction is important: the reforms change how THC presence is dealt with for an eligible group of prescribed patients. They do not remove laws dealing with impaired driving.
When does the new system start?
Not immediately.
Passing Parliament is a major legislative step, but as at 21 September 2026 the Bill is still awaiting assent. The legislation itself provides that the new system will commence on a date or dates appointed by proclamation.
Transport for NSW also needs to establish the registration process and complete the mandatory cannabis-and-driving education module.
The NSW Government currently expects implementation in late 2026 to early 2027.
This is not the end of the conversation
The legislation requires the new medicinal cannabis driver provisions to be reviewed after their first 12 months of operation.
That review will consider whether the policy objectives remain valid, whether the new provisions remain appropriate and whether their implementation has been effective.
That makes the first year particularly important. It should give NSW real-world information about patient registrations, roadside testing, laboratory results, warnings and enforcement under the new model.
We will be watching closely — particularly the ongoing question of how road-safety laws can better distinguish between the presence of THC and actual impairment.
And a reminder: hemp seed oil is not medicinal cannabis
As we discussed in our original article, news like this also shows why clear language around hemp and cannabis matters.
These driving reforms concern medicinal cannabis containing THC.
They are not about hemp seed oil used in food or skincare.
Hemp seed oil, CBD products, prescribed medicinal cannabis and other cannabis extracts are not interchangeable terms, even though they are often blurred together online.
At Made In Hemp, we work with hemp every day as licensed hemp growers, retailers and makers of our own hemp skincare. Helping people understand those differences has always been an important part of what we do.
What should medicinal cannabis patients do now?
For now, do not assume the new scheme has started simply because the legislation has passed Parliament.
Continue following the advice of your doctor or pharmacist and the current NSW driving rules. Do not drive if you feel impaired, drowsy, slowed down or otherwise unsafe to drive.
We will update this information again when Transport for NSW confirms the commencement date, opens the medicinal cannabis driver registry and publishes the final registration and education process.
