OK, so you’ve heard of the brands SSV, Volcano, iolite, Vapir – but how does a weed vaporizer work?
To start asking that question you need to consider two things :
- What is a weed?
- What is vapour?
and after you understand the questions you’ll better understand the question.
How does a weed vaporizer work?
A weed is an organic material that comprises many complex molecules, some are active ad others are simply structural – the stuff that makes the weed solid. When you vape a weed, you are tryig to liberate the subtle components without messing with the structural elements.
When a weed is burned then the energy to produce the heat that actually causes the burning is crated by oxidising the plant itself – an exothermic reaction that is called “fire”. This uses the carbon in the structural plant to heat up the subtle elements of the weed. It is a simple idea but not very controllable – the heat can be pretty hot and the chemicals that you want to release can inadvertently be involved in reactions that can alter or destroy them.
The idea behind a weed vaporizer is that you control the temperature precisely – a model such as the volcano vaporizer will get the correct temperature to within a few degrees – this means that the carbon based skeleton of the plant will remain largely in tact – there will be no smoke, no CO2 and none of the harmful elements you associate with burning weed.
There are subtle differences between the heating and delivery methods of different vaporizers but they all follow the same principal – controlled temperature release of vapours. The things that make it work even better are things such as forced air heating – this heats air and blows the hot air over the herbs rather than heating the organic matter directly – this results in extremely pure vapours. Most of the other differences between brands of vaporizer are stylistic rather than functional.
