The rules

Key rules in Australia

Plain-language summary. The regulator is Therapeutic Goods Administration (TGA).

Possession (no prescription)
Illegal in all states and the Northern Territory; penalties and diversion schemes vary by state. The ACT allows adults limited personal possession (see below).
Prescribed cannabis
Legal when prescribed by a doctor through the TGA Special Access Scheme or Authorised Prescriber pathway and dispensed by a pharmacy. Only Epidyolex and Sativex are registered medicines.
ACT personal use
Since January 31, 2020 adults 18+ in the ACT may possess up to 50 g dried (150 g fresh) and grow 2 plants per person, 4 per household. Sale, supply and public use remain offenses; Commonwealth law is unchanged.
Home grow
Illegal everywhere except the limited ACT allowance; a prescription does not permit cultivation. Commercial cultivation requires Office of Drug Control licences.
Public use
Illegal. Even in the ACT, using cannabis in public or near anyone under 18 is an offense.
Driving
Roadside tests detect THC regardless of prescription. Tasmania has a medical defence since 2017; Victoria's magistrates have had licence-loss discretion for some patients since March 2025; NSW passed a registration-based reform on September 17, 2026, not yet in force.
Advertising
Advertising prescription medicines, including medicinal cannabis, to the public is prohibited under the Therapeutic Goods Act; the TGA issues fines and brings court cases.
CBD products
Low-dose CBD (up to 150 mg a day, adults) was down-scheduled to pharmacist-only in 2021, but no product had been approved for that route by 2026; other CBD requires a prescription.
Age
No statutory minimum for prescriptions, but Medical Board guidance (July 2025) says doctors should avoid prescribing to patients under 18; most clinics accept adults only. ACT personal-use rules apply to 18+.

Summary, not legal advice — rules change; check local law. Last reviewed Sep 2026.

How it works

How cannabis is sold in Western Australia

Western Australia applies the national rules: medicinal cannabis must be prescribed through the TGA pathways and dispensed by a pharmacy, while possession, supply and cultivation without authorization remain offenses. Driving with THC detected is an offense regardless of prescription.

Perth patients mostly see telehealth doctors and fill scripts locally or by post. MedWest Dispensary, a pharmacist-owned shop in Stirling Central Shopping Centre in Westminster, specializes in medicinal cannabis, opens seven days and posts nationwide for a flat A$15. Some earlier in-person options have changed: Emerald Clinics, once in West Leederville, says it has moved its patients to partner clinics.

The state is also a production base. Little Green Pharma, founded in 2016 and headquartered in Wembley, runs an indoor cultivation site in Western Australia and says it launched Australia's first locally grown cannabis medicine in 2018. Like all producers, it sells only through the prescription chain. Western Australian patients who drive should know that roadside testing does not distinguish prescribed THC, and that only Tasmania currently offers a statutory medical defence.
