First: breathe. Here's the Territory sequence.

The NT prescribes medicinal cannabis like everywhere else, but its drug-driving law remains strict and a prescription is not a defence. The October 2026 drink-and-drug-driving package (passed 13 October 2026) toughens penalties for combined drink-and-drug driving and hooning — and contains nothing that softens the position of a patient who tests positive for THC alone. What you do this week matters.

1. The roadside process. A positive saliva screening test leads to further testing, and a confirmed positive means you cannot drive for a period while the sample goes to the laboratory. Refusing a test is its own offence.

2. Laboratory confirmation. Roadside results are indicative; the laboratory result is the evidence. Distances being what they are in the Territory, this can take longer than you'd expect.

3. The charge. Driving with a prohibited drug present and driving under the influence are separate offences under NT traffic law, with the influence offence far more serious. Check your paperwork for which is alleged.

4. Court. Conviction can mean disqualification, a fine and a record. Remote-area licence loss has outsized consequences — work, family and country obligations — which courts can hear about properly only if it's put before them well. That's the case for representation even when the offence looks minor.

What to do this week

What NOT to do

The reform picture

The Territory's own Legislative Scrutiny Committee put the NT on the reform map in October 2026, recommending the Government give further consideration to how presence-based offences treat prescribed patients — but the package that passed contains no patient defence, so the practical position is unchanged. When anything stirs, our Reform Tracker and fortnightly email will carry it first.

If you have been charged, or need to make a decision that depends on the law, speak to a lawyer — small differences in circumstances change outcomes. Driving while impaired by any substance, including prescribed medication, is illegal in every Australian state and territory.
