The ultimate guide to dry herb vaporisers for medical cannabis users

by Jacob Strzeszewski

As medical cannabis becomes more widely used, many patients are exploring healthier methods of consumption. One of the most effective and innovative ways of medicating is the dry herb vaporiser. This device allows users to inhale vapour packed with cannabinoids and terpenes without the harmful byproducts associated with combustion.

In this article, we’ll break down what dry herb vaporisers are, how they work, the types available, and why they’re considered a healthier alternative to traditional smoking methods.

What is a dry herb vaporiser?

A dry herb vaporiser applies heat to ground cannabis flower, releasing its cannabinoids and terpenes in the form of a smooth, aromatic vapour. Unlike smoking, where cannabis is burned, a vaporiser heats the plant material to just the right temperature, avoiding combustion and reducing harmful toxins. Through vaping your medication, the result is a cleaner, more flavourful experience that’s gentler on the lungs and throat.

Vaporisers allow users to control the temperature, which impacts the flavour, intensity, and vapour density. The optimal starting temperature for most devices is around 350°F (175°C), but this can be adjusted up to 400°F (205°C) depending on your preferences. Lower temperatures give a richer flavour, while higher settings produce larger vapour clouds, though with less taste.

How do dry herb vaporisers work?

A dry herb vaporiser heats cannabis using either convection or conduction methods, or a hybrid combination of both.

  • Conduction vaporisers: These vaporisers heat cannabis through direct contact with a hot surface. This method tends to be faster and is ideal for users seeking a potent hit. However, it can sometimes lead to uneven heating, meaning you might need to stir the cannabis occasionally for consistent results.
  • Convection vaporisers: Convection vaporisers use hot air to heat the cannabis, leading to more even heating. This method provides better control over the temperature and ensures that the cannabis doesn’t continue to heat when not in use, making it ideal for users who prefer to take breaks between hits. Convection vaporisers tend to be larger but offer a more consistent experience.

Benefits of using a dry herb vaporiser

Vaping your medication offers a range of health and performance benefits:

  • Healthier for lungs and throat: Combustion when smoking produces harmful carcinogens and chemicals, which can damage the lungs over time. Vaporising eliminates these harmful byproducts, offering a cleaner, smoother inhalation experience.
  • Preserves terpenes and flavour: Vaporising at lower temperatures preserves the delicate terpenes found in cannabis, which are responsible for its flavour and aroma. This ensures a richer and more enjoyable taste compared to the harsh smoke produced by burning cannabis.
  • Efficient dosing: Vaporisers allow for precise temperature control, helping you tailor your experience based on the desired effects. This also ensures more efficient use of cannabis, as the gentle heat extracts the cannabinoids more thoroughly, meaning you use less product for the same or better effects.
  • Cleaner vapour: The vapour produced by a dry herb vaporiser is cooler and less harsh, making it easier on your lungs. With a dry herb vaporiser, you’ll avoid the burning heat and irritants associated with smoking.

Types of dry herb vaporisers

When choosing a dry herb vaporiser, there are a few different options to consider based on your needs and preferences:

  • Portable vaporisers: These are compact and easy to use on the go. Portable vaporisers are perfect for users who want discretion and convenience. Many offer hybrid heating systems and adjustable temperatures, allowing you to enjoy a personalised vaping experience.
  • Desktop vaporisers: If you’re looking for more power and precision, desktop vaporisers are larger devices that require a stationary setup. These are ideal for home use and offer higher vapour production and more control over the vaping process.
  • Hybrid vaporisers: Some vaporisers use both conduction and convection heating, offering the best of both worlds in terms of vapour quality and convenience. Models like the PAX Plus are popular for their versatility, long battery life, and smooth, flavourful vapour.

How to use a dry herb vaporiser: A step-by-step guide

Using a dry herb vaporiser is straightforward, and it doesn’t take long to get the hang of it. Here’s a simple guide to using most vaporisers:

1. Read the manual: Start by reviewing the user manual to ensure you understand your device’s specific charging, grinding, and usage instructions.

2. Charge the device: Ensure your vaporiser is fully charged before use. Portable vaporisers typically charge via USB, while desktop models will need to be plugged into an outlet.

3. Grind your herb: Grind your cannabis to a medium-fine consistency. This ensures even heating and a smooth vapour experience.

4. Pack the chamber: Carefully pack your cannabis into the vaporiser’s chamber. Avoid overpacking, as this can lead to uneven heating.

5. Adjust the temperature: Set the temperature based on your desired effect. Start with a lower temperature (around 170°C) and adjust as needed. Higher temperatures will produce more vapour, but may diminish the flavour.

6. Inhale and enjoy: Take slow, steady inhales. Vaporising offers a smooth experience, so take your time and allow time between each hit to assess how you’re feeling.

Why dry herb vaporisers are the future of medical cannabis consumption

As more people explore ways to consume medical cannabis, dry herb vaporisers have emerged as a popular and effective option. With the ability to control temperature, preserve terpenes, and reduce harmful byproducts, vaporisers offer a cleaner and more flavourful method of medicating.

For medical cannabis patients, vaporising is often the preferred method of consumption, as it delivers precise dosages. Whether you’re new to cannabis or a seasoned user, a vaporiser can enhance your experience and provide a safer, more enjoyable way to medicate.

Considering medical cannabis? A vaporiser could be a good place to start

If you’re considering using medical cannabis for health purposes, a vaporiser can be an excellent way to safely and efficiently consume your medication. Vaporisers allow for precise control over temperature, ensuring you can extract the beneficial cannabinoids and terpenes from your cannabis without the harmful effects of combustion.
