Australia-wide

Can I fly interstate with my prescribed medicinal cannabis?

The law is settled

The short answer

Yes, and no Commonwealth approval, permit or notification exists for it — because the Commonwealth does not regulate you carrying it. It regulates your prescriber's authority to supply it, and that transaction finished when the medicine was dispensed. The practical risk on the day is not legality. It is proving the medicine is yours at a screening point.

General information, not advice. This page describes the law as at the last-checked date shown at the foot of it. It does not take your circumstances into account, and small differences in circumstances change outcomes. If a decision turns on this, speak to someone qualified about your own situation.

What the law actually says

Section 19 of the Therapeutic Goods Act 1989 is the provision every Australian prescription for this medicine is written under, and reading it is the fastest way to see why domestic travel is not a Commonwealth question.

Section 19(1) lets the Secretary approve a person for the importation into, the exportation from, or the supply in Australia of therapeutic goods that are not registered or listed, for use in the treatment of another person. That is the Special Access Scheme, and s 19(1AA) confines it: such an approval must not be granted to a person unless the person is a health practitioner.

Section 19(5) is the other route — the Secretary may authorise a specified medical practitioner to supply specified goods to specified classes of recipients. Section 19(6) narrows who may hold one: a practitioner in a class prescribed by the regulations, with the approval of an ethics committee, and only in relation to prescribed classes of recipients. Section 19(7A) lets the Minister make rules extending that to a class of health practitioners.

Every one of those is about a practitioner's authority to supply. Not one of them regulates a patient in possession of what was supplied, and none of the three acts named in s 19(1) — importation, exportation, supply — describes carrying a dispensed medicine from Perth to Adelaide. There is no Commonwealth domestic-travel permit because there is no Commonwealth provision that a domestic flight engages.

The traveller's exemption is about a different thing, and this is the error worth avoiding. It concerns bringing medicines into Australia — the importation limb. Citing it for a domestic flight is citing an import rule for a journey that crosses no border, and the fact that it sets out conditions makes it read like conditions you have to satisfy. You do not.

The Commonwealth's other statute here points the same way. The Narcotic Drugs Act 1967, whose s 8DA states the purpose of its medicinal cannabis chapter, exists to enable cultivation, production and manufacture so that products are available to patients. It is a licensing scheme aimed at growers and manufacturers. It has never been a patient pathway and creates no patient obligation.

What this page does not tell you. Whether your possession is lawful is a state question, answered by the drugs-and-poisons Act of the jurisdiction your medicine was dispensed under — and those eight Acts are not identical. This page has not checked all eight and does not claim to. It tells you that the Commonwealth is not the obstacle people expect it to be, which is a narrower and more useful thing than a reassurance covering ground nobody here has read.

What happens if it goes wrong

The realistic failure is not a charge. It is a delay at screening while somebody satisfies themselves about what you are carrying, and every part of that is manageable in advance.

Screening officers are looking for security threats, not conducting drug investigations, and a dispensed medicine in a labelled pharmacy container with your name on it is an ordinary thing for a person to have. What creates a problem is loose product in an unlabelled container, which is indistinguishable at a glance from the thing that is actually illegal.

What to carry

  • The dispensing label, still attached, with your name on it. This is the single thing that turns a conversation into a non-event.
  • A copy of the prescription or a letter from your prescriber. Not legally required anywhere for a domestic flight, and worth having for the same reason you keep a receipt.
  • Only what you need for the trip. Quantity is what turns a possession question into a supply question, in every jurisdiction.

What to say

  • "It's a prescribed medicine, here's the label." Then stop. Answer what is asked.
  • If you are asked for more, offer the prescriber's letter. Volunteering a diagnosis is not required and cannot be undone.

What not to do

  • Do not decant it. Out of its labelled container it stops being evidently yours, which is the whole point of carrying it.
  • Do not cite the traveller's exemption. It is an import rule, and quoting it at a domestic screening point invites a question about a border you are not crossing.
  • Do not assume this page settles your state's position on possession. It does not, and says so above.
