NSW Drug Driving Laws and Proposed Medicinal Cannabis Reforms

Thousands of Australians now legally use medicinal cannabis, yet many NSW drivers are surprised to learn they can still be charged with a drug driving offence even if they have a valid prescription.

Recent proposals to change NSW drug driving laws have renewed debate about whether medicinal cannabis patients should be treated differently from recreational drug users.

Can You Be Charged if You Have a Medicinal Cannabis Prescription?

Yes.

In NSW, police conduct roadside drug testing for THC (the active ingredient in cannabis), MDMA, cocaine and methamphetamine.

Unlike drink driving offences, police do not need to prove that you were impaired. If THC is detected in your system while driving, you may be charged, even if:

  • You have a valid medicinal cannabis prescription;
  • You consumed the medication as directed by your doctor; and
  • You were not affected by the medication at the time of driving.

What Changes Have Been Proposed?

There have been growing calls for NSW to reform its drug driving laws.

Some politicians and advocacy groups have proposed allowing medicinal cannabis patients to rely on a defence where:

  • The cannabis was legally prescribed; and
  • The driver was not impaired.

Supporters argue that the current law unfairly punishes patients who are using prescribed medication responsibly.

At the time of writing, however, NSW continues to operate a zero-tolerance approach to THC detection.

What Happens if You Are Charged?

A drug driving conviction can result in:

  • A fine;
  • Licence disqualification;
  • A criminal record in some circumstances; and
  • Increased insurance and employment consequences.

The outcome will depend on your traffic history and the specific circumstances of your case.

Do Not Assume You Have No Defence

Every case should be carefully reviewed.

Issues can arise regarding the roadside testing process, laboratory analysis, or whether the prosecution can prove the offence beyond reasonable doubt.
