How-to Use Medicinal Cannabis Safely

Forms of Medicinal Cannabis and Consumption Methods:




  • The primary active ingredients in medicinal cannabis products are CBD (cannabidiol) and THC (tetrahydrocannabinol). These are used in various forms, including oils, liquid capsules, oro-mucosal sprays (administered under the tongue), and topical applications (applied to the skin).

  • Oral oils and liquid capsules are the most commonly prescribed methods in Australia, accounting for about 80% of prescriptions. They have a slow onset of 30 to 60 minutes but last for 8 to 24 hours.

  • Vaporising is another method, though currently, only one vaporiser is TGA approved, the Mighty Medic. It has a very rapid onset of about 90 seconds and a shorter duration of 2 to 4 hours.

  • Oro-mucosal sprays also have a slow onset and long duration similar to oral forms.

  • Topical applications are less common, with ongoing research into their efficacy. THC is poorly absorbed through the skin, while CBD shows better absorption rates.

  • It's important to know that smoking medicinal cannabis is not supported by the TGA due to the associated health risks. It is however not illegal to smoke it if you are prescribed it, the TGA

As of 2023, the legal status of smoking medicinal cannabis in Australia remains a complex issue. The existing laws and proposed bills don't explicitly address the legality of smoking medicinal cannabis. This means that technically, you aren't breaking any laws by smoking it. However, the Therapeutic Goods Administration (TGA) guidelines do provide some insight.

The TGA states that botanical cannabis, intended for medicinal purposes, should be vaporised but not smoked. This suggests that while medicinal cannabis is legal with a prescription, its consumption by smoking is not within the recommended methods outlined by the TGA. The TGA's stance seems to be more about promoting healthier consumption methods rather than a direct legal prohibition on smoking. There are no current bills on the table in parliament to make smoking of medicinal cannabis illegal either.


For further detailed information, it's advisable to consult healthcare professionals and relevant Australian health and regulatory websites. Additional information can be found on the TGA website.
