Typically, vaporizers – often called vapes or vape pens, depending on their size – are filled with a dry herb or concentrated material – such as a dab of wax or oil cartridge. The material of choice is then heated electronically below its combustible point. This releases the compounds of the material within a vapor, which the user can then inhale. Vaporizers differ from smoking in a few different ways. Smoke is the direct result of combustion. While it burns, smoking also releases new chemicals through oxidation. Conversely, vaporization is a more gas-like release, occurs at a lower temperature and does not reach the point of combustion. It only releases the chemicals that are found in the material itself – unlike smoking and its new oxidation-based chemicals.
