Medicinal cannabis can be prescribed in the NT, but THC remains a strictly prohibited drug: driving with any detectable THC is an offence regardless of prescription, and the Traffic Act's section 29 defence does not extend to THC. The Traffic Legislation Amendment (Drink and Drug Driving and Hooning) Bill 2026 passed the Legislative Assembly on 13 October 2026 — passive breath screening, a combined drink-and-drug offence, impoundment and hooning tiers — but it contains nothing for medicinal cannabis patients; the Legislative Scrutiny Committee has recommended the Government give the presence-based-offence question further consideration.

Medicinal cannabis and driving in the NT: where the law stands
Medicinal cannabis is prescribed in the Northern Territory like everywhere else in Australia — but the Territory's drug-driving law remains strict. It is an offence to drive with a prohibited drug in your body, detected by a police saliva or blood test, and THC is a strictly prohibited drug: a valid prescription is not a defence, and the Traffic Act's section 29 defence for drugs administered under treatment does not extend to THC. Assume any detectable THC in a test exposes you to a charge, prescription or not — and never drive impaired. Impaired driving is a separate, more serious offence.
The October 2026 package: tougher drink-and-drug laws, nothing for patients
On 13 October 2026 the NT Legislative Assembly passed the Traffic Legislation Amendment (Drink and Drug Driving and Hooning) Bill 2026. The Government's announcement lists what it does:
- Passive roadside breath screening using a handheld device.
- A new combined offence for drivers detected with both a high-range blood alcohol concentration and drugs in their system, carrying stronger penalties — news reporting put the maximum fine at about $9,700 and imprisonment at up to two years.
- Vehicle impoundment — 14 days for a second high-range drink or combined drink-and-drug driving matter.
- A serious-hooning tier (dangerous driving, dangerous speed, pursuit) with immediate impoundment: 7 days for a first offence, 14 for a second, 28 for a third.
- Interstate drink- and drug-driving offences count as prior offences under NT law.
None of that changes the position for medicinal cannabis patients. Presence alone stays an offence regardless of prescription, and the new combined offence is one more way a patient who has had a drink could face a more serious charge. Before passage, the Legislative Scrutiny Committee's report on the Bill (tabled 7 October 2026) noted the national movement on presence-based offences — NSW's now-assented registration Act, and committee recommendations in WA and SA — and recommended the Government give further consideration to how the law treats prescribed patients. The Government's response was tabled on 13 October 2026; the package as passed contains no patient defence.
Current penalties for drug presence
Per the NT Government's penalties page: a first offence may be dealt with by a $400 traffic infringement notice plus 6 demerit points, or a court-imposed fine of 5 penalty units, with maximum imprisonment of 3 months. A second offence carries a minimum 3-month disqualification (court fine of 7.5 penalty units on that path), a subsequent offence minimum 6 months, and maximum imprisonment of 6 months. "Second offence" includes prior findings of guilt for driving under the influence or refusing saliva, blood or breath tests. Figures re-index; check the penalties page for current values.

Why this page still matters
The NT has now been formally put on the reform map — by its own scrutiny committee. When NSW's scheme commences and Victoria's trial reports, pressure lands on the remaining strict jurisdictions, and a small parliament can move quickly. This page and the Reform Tracker will carry it first.
Common questions
Can I drive in the NT with prescribed THC in my system? No. THC is strictly prohibited: detectable THC exposes you to drug-driving charges regardless of prescription, and impaired driving is a separate, more serious offence.
Is the NT reforming its law? Not for patients. The October 2026 package toughens drink-and-drug driving and hooning but leaves THC presence strict. The Scrutiny Committee has recommended the Government give the medicinal cannabis question further consideration — watch the Reform Tracker.

Quick answers for Northern Territory
Can I drive with a medicinal cannabis prescription in Northern Territory?
Medicinal cannabis can be prescribed in the NT, but THC remains a strictly prohibited drug: driving with any detectable THC is an offence regardless of prescription, and the Traffic Act's section 29 defence does not extend to THC. The Traffic Legislation Amendment (Drink and Drug Driving and Hooning) Bill 2026 passed the Legislative Assembly on 13 October 2026 — passive breath screening, a combined drink-and-drug offence, impoundment and hooning tiers — but it contains nothing for medicinal cannabis patients; the Legislative Scrutiny Committee has recommended the Government give the presence-based-offence question further consideration.
Is a valid prescription a defence to drug driving in Northern Territory?
No. In Northern Territory, driving with detectable THC is an offence regardless of a valid prescription. Driving while impaired is a separate, more serious offence everywhere in Australia.
What happens if I test positive at a roadside drug test in Northern Territory?
You will be unable to drive for a period while your sample goes to a laboratory, and charges typically follow laboratory confirmation. See our step-by-step guide, “Tested positive in Northern Territory: what happens next”, and get legal advice early.
What is the penalty for drug driving in Northern Territory?
[VERIFIED 2026-10-16 against nt.gov.au drug driving penalties] First offence: $400 traffic infringement notice + 6 demerit points, or court-imposed fine of 5 penalty units; max imprisonment 3 months. Second offence: $400 TIN + 6 demerits or court fine of 7.5 penalty units; minimum 3 months disqualification; max imprisonment 6 months. Subsequent: $400 TIN + 6 demerits or court fine of 7.5 penalty units; minimum 6 months disqualification; max 6 months imprisonment.
How long does THC stay detectable after use, and does it matter in Northern Territory?
Detection windows depend on how often and how much you use, and on the test used. Our guide “How long does THC stay detectable” explains the windows for oral fluid, blood and urine. What matters for a charge is whether THC is present at the time of driving, not when you last used.
