Ultimate Guide to Vaping Medicinal Cannabis, 2024

What Is Vaping?

Vaping is the process of heating cannabis flower or extract at a high temperature without burning it, allowing cannabinoids and terpenes to be released in the form of a vapour, which is then inhaled. 

Vaping is one of two inhalation methods for consuming cannabis flower, alongside smoking. In medicinal contexts, vaping is the recommended method while smoking is not because it reduces the amount of undesired hydrocarbons being absorbed into the body while also alleviating the need for tobacco, which can lead to addiction and other serious health issues. Vaping may also allow for a more precise dose to meet the therapeutic needs of a patient, given that less of the THC dose is lost in side stream/combustion.

As of 2022, flower has become the second most approved form of medicinal cannabis) product in Australia.¹ This implies that a large number of patients are using an inhalation method to consume their cannabis medication.

Inhalation delivery methods, like vaping, allow cannabinoids to be absorbed directly into the bloodstream through the lungs, making this the preferred method for some patients who require rapid relief of symptoms.

How Do You Vaporise Medical Cannabis?

To vaporise cannabis, you’ll need a device known as a vaporiser (or vape). While a vaporiser can include any device that releases a particular substance in the form of vapour, doctors will generally recommend a medical-grade dry herb vaporiser for use with medicinal cannabis. In Australia, there is only one brand of TGA-approved dry herb vaporisers that should be used with MC – the MIGHTY MEDIC and MIGHTY+ MEDIC. Dry herb vapes allow you to vape cannabis flower without burning it so that the plant’s oils can be released as a vapour. With a dry herb vape, the patient receives only the bioactive cannabis compounds needed to experience the medicinal benefits of cannabis – and none of the chemicals or additives that might be found in some other types of commercially available vapes, such as vape pens and cartridges.

When using a dry herb vaporiser, you can also vaporise your prescribed cannabis flower at the optimal temperatures for cannabinoid and terpene activation by using the vaporiser’s temperature setting. This can make it easier to control your experience by adjusting the temperature of your vaporiser to the boiling points of terpenes and other compounds within your cannabis flower to achieve desired benefits.

As always, you should follow the specific instructions for your vaporiser as well as your doctor’s advice for using your vaporiser and treatment and only use your medication as prescribed.

Is It Legal to Vape Medicinal Cannabis in Public?

It is legal to vape medicinal cannabis in public smoking areas. There are no laws which prohibit the use of medical-grade vaporisers for consuming legally prescribed medicinal cannabis treatments as long as you are in a public smoking area and are not causing a disturbance to others in your proximity. This means that because your cannabinoid medication is a highly regulated substance prescribed to you only, you will need to ensure you are at a safe distance from others, especially children, who may inhale your medication passively. 

You should always carry your medication in its original packaging with the pharmacy label attached as well as any documentation (such as your script and/or approval letter) and identification that can verify your legal patient status if you are stopped or questioned by law enforcement. 

The patient guidance section of the Therapeutic Goods Administration (TGA) website states that cannabis flower treatments or ‘raw (botanical) cannabis’ should be ‘vaporised but not smoked’ for medicinal purposes. Therefore Polln does not recommend smoking your cannabis treatments anywhere, including in public smoking areas, as it is not supported by the TGA.

What Are the Differences Between Vaping vs. Smoking?

Vaping Medicinal Cannabis 

Some of the the reasons that vaping medicinal cannabis flower is the only recommended inhalation method, as opposed to smoking , may include:

• Rapid onset and fast relief – first effects may occur within 90 seconds and reach a maximum after 15 to 30 minutes before wearing off after 2–4 hours. This may be useful for symptoms and conditions where immediate relief is required.
• Higher concentrations of active ingredients – vaporising heats the cannabis without burning it,² which maintains the concentrations and quality of the active ingredients like cannabinoids and terpenes.³
• Temperature control – patients can control the temperature of their vaporiser to achieve desired therapeutic effects based on the boiling points of their cannabis medicine’s ingredients, including cannabinoids and terpenes.
• Potential reduction in overall consumption – because of the enhanced cannabinoid and terpene uptake, reduced cravings due to no tobacco, and the ability to easily pick up and put down the vaporiser as needed, patients may be more likely to stay within their therapeutic window and achieve maximum therapeutic benefits with less cannabis flower than they would need to use when smoking. This can reduce the amount of medication needed and may save the patient money over time.
• Less carcinogens and safer than smoking
• Legal in public smoking areas with a prescription
• More discreet than smoking

Vaping comes with its own risks and side effects. It's important to discuss your suitability for vaping with your prescribing doctor and only use your cannabis treatments and vaporiser as advised.

Is Vaping Safe?

Although vaping medicinal cannabis – particularly with a TGA-approved vaporiser – is known to be safer than smoking, it can still come with health risks. In comparison with smoking, vaporisation has been shown to produce the purest stream of cannabinoids and terpenes while containing less than 1/1000th of the hazardous substances associated with combustion.⁶ But not all vaping devices are created equal.

The negative health risks associated with vaping, which may include lung injuries, headaches, heart issues and more, are often related to the use of illegally manufactured vape products⁷ and vape products with chemical profiles that are closer to that of e-liquids. Illegally manufactured or modified vape products and vape products containing harmful chemicals such as vitamin E acetate significantly increase your risk of damaging your lungs. While harmful by-products, including microbial contaminants, harmful chemicals, carcinogens, and addictive substances like dextromethorphan, are often found in black market cannabis oils, unapproved vape pens, cartridges and e-liquids. Vaporiser injuries from unapproved vapes can also range from burns to accidental liquid ingestion and a lung disease known as 'popcorn lung.'

To be safe and effective, prescribed medicinal cannabis flower should be vaporised using a TGA-approved dry-herb vaporiser within the correct temperature range as advised by your prescribing doctor.

What Are the Ideal Medicinal Cannabis Vape Temperatures?

Knowing the different boiling points of the various cannabinoids, terpenes and other properties within your medicinal cannabis flower will help you adjust your vape temperature for the safest and most therapeutically beneficial experience. Set your vape temperature too low, and you run the risk of missing out on the potency of your medicinal cannabis flower, as certain compounds will not have reached the minimum temperature required for them to activate. Similarly, if you set your vape temperature too high – especially at temperatures higher than 230°C – you run the risk of inhaling more toxic compounds and degrading the active ingredients in your treatment so that they are no longer beneficial to your health.

The optimal temperature range of vaping medical cannabis is between 180–210°C – but there is room for experimentation within this temperature range to find what works best for you and the ingredients in your flower. While cannabinoids like THC and CBD will ‘activate’ or ‘evaporate’ at lower temperatures within this range, terpenes like linalool or limonene have a higher boiling point, meaning they activate at higher temperatures within that optimal range. Work with your prescribing doctor to understand the ideal vape temperatures for you and your treatment plan. 

Storz & Bickel

Storz & Bickel, owned by Canopy Growth Corporation, are currently the first and only TGA-approved medical vaporisers available in Australia to be used with cannabinoid medicines. These devices are in the Australian Register of Therapeutic Goods (ARTG) (ARTG Identifier 319028).

The MIGHTY MEDIC and MIGHTY+ MEDIC are intended to be used with dried medicinal cannabis flower. They are battery-operated and portable, allowing for dose administration at home and on the go.

The VOLCANO MEDIC can be used with dried medical cannabis flower or liquid cannabinoids dissolved in alcohol. It is a desktop vaporiser which can be used at home, in hospital settings and in medical practices. In one 2016 study, the VOLCANO MEDIC was one of 4 electrically-driven and temperature-controlled vaporizers that were found to “efficiently decarboxylate acidic cannabinoids and release reliably the corresponding neutral cannabinoids into the vapour,”8 suggesting that the device may be a safe and efficient administration of medicinal cannabis and cannabinoids.

Always use your cannabinoid medicine and devices as advised by your prescribing medicinal cannabis doctor.

The Bottom Line

Vaping is just one of a number of delivery methods used to administer medicinal cannabis. It may be suitable for patients  who require rapid relief from their symptoms, as effects can typically be felt within minutes. Although vaping with a TGA-approved vaporiser is legal in public smoking areas, you should always keep your medication in its original packaging with the pharmacy label attached and carry your script and identification so you can verify your patient status. And always be mindful of people around you who should not be able to inhale your medication passively.

If you are interested in talking to a doctor about medical cannabis, we recommend speaking to a professional who is an expert in medicinal cannabis treatments so they can help determine which, if any, medicinal cannabis treatment(s) may be right for you while guiding you in the use of any required devices, such as a medical vaporiser.
