Weed vaporizers operate by heating herbal products to the appropriate temperature so the chemicals within the weed boil off into a vapor which can be inhaled. This is significantly healthier compared with smoking or injesting the herb since it gives a much better level of control over quantity and there are significantly less unintended side effects.
Weed vaporizers use numerous methods of heating up the herb which include thermal conduction, thermal radiation and convection. Thermal conduction is the most common method where the substance is put onto a surface that is heated up by butane or a similar heat source which in turn heats up the herb that causes it to release its chemicals in vaporous form. Radiation makes use of a powerful light source to send energy into your plant and is less commonly used. Convection vaporizers heat up the air in the vaporizers and having the air heat the herb.
Because different substances have got different natural vaporization temperatures it is crucial for a weed vaporizer to be able to control the temperature. To provide an example, marijuana possesses a vaporization temperature of 177°C whereas tobacco has a vaporization temperature of 140°C. Being able to precisely set the most suitable temperature means that you get the most chemicals out of your herbs.
Some weed vaporizers include digital displays that display both the actual and pre-programmed temperatures to help you set it specifically as you would like it. It truly is a matter of personal taste however for marijuana it needs to be over 140°C which is the temperature at which trace amounts of THC can be found but below 200°C as toxins start forming at such a high temperature. Almost all vaporizer owners tend to stick to temperatures around 185°C since this is well below the toxin limit but high enough so that suitable levels of THC and vapor make their way into the collection/inhalation device.
One point to understand is the density of the vapor will not make any difference to the effect that inhaling the vapor has on you. Less dense vapor that you would get with lower temperatures can contain just as much THC as the thicker vapor you will get by using increased temperatures.
