In Australia, cannabis medicines are regulated within a medical framework to ensure the health and safety of patients. The prescription of cannabis medicines is regulated at a state and territory level.
While exemptions may apply under certain conditions for travellers carrying cannabis medicines into Australia, these exemptions only apply to people who have a prescription given by a medical practitioner and have had the cannabis medicine supplied in accordance with that prescription (i.e. by dispensing through a pharmacist, rather than supply through some other form of retail or other mechanism). Cannabis medicines provided in countries by mechanisms other than a prescription may not meet the legal requirements of the Customs (Prohibited Import) Regulations 1956. More information is on The Office of Drug Control’s website.
In NSW, unless a cannabis medicine* has been prescribed by a doctor authorised by the NSW Ministry of Health, it will constitute an illicit product under section 10(2)(c) of the NSW Drug Misuse and Trafficking Act 1985. Compliance with this Act is at the discretion of NSW Police.
* Except for a cannabidiol-only medicine which is included in Schedule 4 of the Poisons List, which only requires the prescriber to have authority from the Therapeutic Goods Administration to prescribe it.
