Cannabis can be prescribed in its natural, dried flower form. These medicines are not prescribed for smoking, as combustion releases harmful compounds.
Instead, flower medicines are inhaled using a medical herbal vaporiser (sometimes called a dry herb vaporiser), which gently heats the flower to release active cannabinoids and terpenes without burning. These devices differ from nicotine or e-liquid vapes and are designed specifically for medicinal use.
If you are new to cannabis flower medication, you may need to purchase a grinder and herbal vaporiser. Our partner pharmacy, Petal & Bud, stocks approved accessories, with discounts available for eligible access or waitlist patients.
Once you have your grinder, vaporiser, and prescribed flower, follow these five simple steps:
Place a small amount of dried cannabis flower (approximately 200–250 mg) into a grinder and twist several times until evenly ground.
Transfer the ground flower into the vaporiser bowl. Fill the chamber so it is level but not tightly packed, allowing airflow through the material.
Reattach the vaporiser lid, select your desired temperature (typically between 175–190 °C), and power on the device. Begin at a lower temperature and adjust upward to find your optimal setting.
Draw the vapour slowly through the mouthpiece and exhale immediately. Coughing can occur—if persistent, lower the temperature or reduce inhalation volume.
When the vapour becomes harsh or flavourless and the flower turns brown, the session is complete. Empty the spent material and brush or wipe the chamber and mouthpiece to keep the device clean for next use.
Vape cartridges contain purified cannabis extract in a ready-to-use form. They are typically combined with a compatible battery device to deliver inhaled doses in a consistent and convenient way.
These devices differ from herbal vaporisers, as they use concentrated cannabis oil rather than dried flower. Cartridges are available in a range of formulations to suit individual prescriptions.
Ensure your vape battery is charged and compatible with the cartridge.
Gently screw or click the cartridge onto the battery until secure—do not overtighten.
Activate the device according to the manufacturer’s instructions. If adjustable, start on a low temperature or voltage setting and increase gradually as needed.
Place your lips on the mouthpiece and draw in gently for 2–3 seconds. Exhale immediately. Wait a few minutes between inhalations to assess effect.
Detach the cartridge when not in use and store upright in a cool, dark place. Keep out of reach of children and away from heat or sunlight.
Sublingual oils are liquid cannabis formulations designed for absorption under the tongue. This method allows cannabinoids to enter the bloodstream directly through the oral mucosa, avoiding digestion and providing steadier onset compared to inhalation.
Oils are available in a variety of ratios and concentrations to meet individual patient needs.
Wash your hands and shake the bottle gently. Measure the prescribed dose using the supplied dropper.
Place the drops directly under your tongue. Avoid touching the dropper to your mouth to maintain hygiene.
Keep the oil under your tongue for 60–90 seconds before swallowing. This allows absorption through the oral mucosa.
Effects may begin within 30–90 minutes. Avoid eating or drinking for at least 10 minutes after administration.
Replace the cap tightly and store the bottle upright in a cool, dark place, away from heat and direct sunlight.
Lozenges and pastilles are solid oral formulations that dissolve slowly in the mouth, allowing cannabinoids to be absorbed through the mucous membranes. This provides a controlled and discreet method of administration without inhalation.
They are particularly suitable for patients who prefer a measured, longer-acting dose.
Confirm the prescribed number and strength of lozenges or pastilles before use.
Position the lozenge between your cheek and gum, or under the tongue.
Let it dissolve completely without chewing or swallowing. This ensures absorption through the oral mucosa.
Do not eat or drink while the lozenge is dissolving or for 10 minutes afterward.
Keep in the original packaging, stored in a cool, dry place away from heat and moisture. Always keep out of reach of children.
