A vaporizer (or evaporator) is a device used to inhale substances such as cannabis or other herbs.
In contrast to a pipe or joint, the plant material is not incinerated in a vaporizer but heated. Additionally, terpenes and substances such as tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol (CBN) are free from it. Since the combustion point is not reached, no benzene, toluene, or naphthalene is released. Research shows that there are no substances like carbon monoxide and tar released when using a modern vaporizer at low temperatures.
While with a joint or pipe, 60% to 80% of the smoke is lost in the air due to combustion, this can be avoided with a vaporizer because the vapors can be collected in a reservoir.
The vaporizer is particularly popular among medical users. On one hand, it is considered a less harmful way of using cannabis, and on the other hand, the effects differ from those of a joint. Users report that vaporization makes them feel more active rather than feeling stoned, hungover, or lazy.
