The  cannabis vaporizers  are devices that have the ability to heat the plant material without burning it. The techniques used to achieve this are either  by heating the chamber  used to contain the plant material ( conduction ), or by  heating the air  passing through the plant material ( convection ).


Conduction or convection cannabis vaporizers?


In the case of a vaporizer, the term  conduction  means that the plant material is placed in a heating chamber and brought to high temperatures. The plant matter is in direct contact with the heating chamber and, as the temperature rises, cannabinoids and terpenes begin to evaporate.


In the case dl in operation Convention , cannabinoids and terpenes are released through the hot air passage through the plant material. In convection cannabis vaporizers, the heating element is located outside the heating chamber. This allows the plant matter to avoid direct contact with the heat source.


Both methods have advantages and disadvantages and hybrid conduction / convection cannabis vaporizers can be encountered on the market .


Adjust the temperature in cannabis vaporizers


The different substances contained in Cannabis have  different evaporation temperatures ; only by reaching the evaporation point of each substance, the constituents of Cannabis are released and so can be inhaled. Depending on the model and price, cannabis vaporizers can have one, few or different temperature settings. 


On the market it is possible to find models with both fixed and variable temperature regulation .


Those with variable temperatures are usually the most expensive, but they also allow better control of the temperature and, therefore, of the heat point suitable for evaporating the phytocompound sought. This option is therefore recommended when purchasing a vaporizer for therapeutic purposes.


Models with manual temperature selection usually have a range from 40 ° C up to 230 ° C.


Around this temperature (230 ° C) it is possible for the combustion process to begin , so this is usually the maximum temperature reached by cannabis vaporizers.


Tetrahydrocannabinol ( THC ) starts to evaporate at temperatures as low as 140 ° C and evaporates almost entirely at 185 °. Cannabidiol ( CBD ) begins to evaporate around 200 ° C and almost completely evaporates around 240 ° C.


The temperatures reached while smoking are much higher: 900 ° C during one hit and around 400 ° C between one hit and the next. 


These high temperatures generate a large amount of toxic and irritating by-products that should be avoided by all and especially by patients. It is the  low temperatures and the lack of pyrolysis (or combustion) that make vaporization an efficient and healthy form of cannabis intake


Other benefits of cannabis vaporizers


The popularity of cannabis vaporizers has grown in popularity in recent years, as they offer numerous benefits for both recreational users and, especially, users of medicinal cannabis.


cannabis vaporizers: better efficiency, lower doses, greater savings


Vaporizing allows the consumer to use the same cannabis flowers more than once, as they are not burned and reduced to ashes by combustion. For this reason, once the required dose is reached, the same  Cannabis can be reused  for a subsequent session.


For example, since some cannabinoids may still be present in the vaporized material, some people employ such flowers to make cannabis oil. Nothing is wasted!


With the same effects, the use of the vaporizer reduces the necessary quantity of plant material. With vaporization you can get the same beneficial effects given by the act of smoking, but with the advantage of using lower doses. This is what makes vaporization a lighter form of intake for the consumer’s wallet as well .


cannabis vaporizers: no smoke, no smell


One of the practicalities of cannabis vaporizers is that they produce no smoke and virtually no odor . This allows it to be used even in places where the smell of smoke could cause annoyance.


Vaporization: excellent flavor of cannabis vaporizers


The first thing consumers notice when first vaping is a very pleasant taste.


The differences between smoking and vaping on a taste level are incredible. Vaporizing allows you to appreciate the flavors and aromas of different cannabis varieties. (13)  The taste of cannabis is due to the presence of  terpenes , volatile molecules responsible for the characteristic odors of flowers and fruits in nature.


How to choose the cannabis vaporizers


Nowadays you can come across various brands and models of cannabis vaporizers and choosing the right vaporizer can be a long and daunting process. Below, a series of tips that can facilitate the choice process for the user.


First you need to decide if you want a stationary or portable vaporizer . A portable vaporizer  is more practical  as it can be carried and used discreetly almost anywhere. Generally,  stationary devices are more efficient  because they are not limited by small size but a recent study has shown that some portable devices are as efficient as stationary devices. (14)


Composition of the heating chamber and mouthpiece


It is important for the user to pay attention to the materials that make up the parts of the vaporizer in contact with heat, such as the heating chamber and the mouthpiece.


It is recommended that these  materials are inert  and that they do not react to heat releasing toxic products or altering the flavor of the plant matter.


Models that have a ceramic heating chamber, as well as a glass mouthpiece and connecting means (between the heating chamber and mouthpiece) are therefore preferred  .


Some cannabis vaporizers have a heat-generating element, such as a small coil, in the heating chamber. These vaporizers  are not recommended since the coil, becoming incandescent, starts a combustion of the plant material  in a very similar way to what happens when you smoke.
