How does a vaporizer work?

Every vaporizer works on the same principle.
A vaporizer heats herbs or medicinal oils/concentrates to the temperature required to vaporize them, so that the active ingredients of the herbs are released. The vaporization is done without the production of toxins that would happen if the herbs were burned. To do this, a vaporizer must provide enough heat to the herbs inside the chamber. At a certain temperature (varies depending on the type of herbs) the herb/oil/concentrate releases the active substances. There are vaporizers exclusively for herbs or exclusively for medicinal oils – concentrates or for both.

Vaporizers are available in portable and desktop sizes.

Another basic categorization of vaporizers is related to how heat is generated and transferred to the chamber where the herb is vaporized. The heat source is usually an electric heater (powered by a battery or outlet) or the flame from a lighter.
A vaporizer transfers heat to the herb either through a solid material (conduction heating) or through a fluid material (convection heating) or both.
