Article 5 - Understanding Your Vaporiser: Device Types, Delivery Mechanics, and What Reaches the Bloodstream
Share
Not all vaporisers work the same way. The device your clinic recommended, the one your friend uses, and the one you found through your own research may all be called vaporisers. They are not all delivering the same thing.
Understanding how your device works is not optional knowledge for a CBPM patient. It is the difference between using a medical device correctly and using it as if it were a consumer product. The distinction matters for outcome.
The two heating methods
Every vaporiser uses one of two heating methods: conduction or convection. Some use both.
Conduction heats the material by direct contact with a heated surface. The material sits against or near the heating element and absorbs heat from it. Conduction devices are generally simpler in design, heat up faster, and tend to be more compact. The limitation is consistency. Material closest to the heating surface receives more heat than material further away. Uneven heating means uneven activation. Stirring or repositioning the material between draws helps, but the variable is structural.
Convection heats the material by passing hot air through it. The air is heated before it reaches the material, and the material vaporises as the airflow passes through. Convection delivers more even activation across the full load. It is more consistent dose to dose. Convection devices are generally larger, take longer to heat, and require a draw technique that maintains consistent airflow.
Hybrid devices use both. A heated surface provides initial activation, with convection airflow completing the process. Hybrids aim to combine the fast heat-up of conduction with the consistency of convection. In practice, performance varies by device.
What this means for your medicine
The heating method affects which compounds activate, in what concentration, and in what order. A conduction device may activate surface-facing material fully while leaving inner material underactivated. A convection device delivers more uniform activation but is more sensitive to draw technique. Too fast and the air cools before full activation. Too slow and temperature builds unevenly.
Your prescribed strain has a cannabinoid and terpene profile selected for your condition. The device is the mechanism through which that profile reaches you. If the device is not suited to the material, or is not used correctly, the profile you receive is not the one that was prescribed.
Draw technique guidance should come from your device manufacturer's instructions or your prescriber. Do not rely on trial and error alone. The variables involved affect therapeutic outcome, and they are worth getting right from the start.
Delivery method within the device
Beyond heating method, delivery method is a second variable. The three primary options in certified CBPM vaporisers are direct draw, whip, and balloon.
Direct draw means inhaling directly from the device mouthpiece. The vapour travels the shortest distance at the highest temperature. Compound retention is highest with direct draw.
A whip is a length of tubing that connects the device to the mouthpiece. Vapour cools as it travels through the whip. Terpene dropout increases with distance and temperature drop. A longer whip means a cooler, lighter draw with reduced terpene concentration. Some patients prefer this. It is not the same medicine.
A balloon fills with vapour and sits before the patient inhales. Compounds begin to degrade from the moment the balloon is filled. The longer the balloon sits, the more degradation occurs. Balloon delivery is often preferred by patients who need a softer, slower draw, or who need to medicate in stages. The trade-off is compound stability.
Certified versus uncertified devices
In the UK CBPM pathway, vaporisers used with prescribed flower should be certified medical devices. Storz and Bickel devices, the Mighty+, the Volcano, and their Medic variants, are DIN EN 60601 certified. That certification means the device has been tested to a defined standard for safety and performance.
Uncertified devices are in use across the patient population. They may produce vapour. They are not operating to a medical standard, have not been tested to one, and cannot be assumed to deliver consistent or safe output. Using an uncertified device with prescribed medicine is outside the prescription pathway.
Device condition compounds every variable here
A conduction device with blocked screens is not heating consistently. A convection device with a contaminated airpath is not delivering clean airflow. A hybrid device with degraded seals is not maintaining the controlled environment it was designed to create. Every mechanical variable discussed in this article is amplified by poor maintenance.
As established in Article 2 and Article 3 of this library, device condition is a clinical variable. Understanding your device type is the first step. Maintaining it to standard is the next.
