Vaporizer (inhalation device)

A vaporization heat wand and vaporization chamber bowl used to deliver vapor through a water pipe

A vaporizer or vaporiser, colloquially known as a vape, is a device used to vaporize substances for inhalation. Plant substances can be used, commonly cannabis, tobacco, or other herbs or blends of essential oil.[1] However, they are most commonly filled with a combination propylene glycol, glycerin, and drugs such as nicotine (e.g. extract from tobacco) or tetrahydrocannabinol as a liquid solution.[2]

Vaporizers contain various forms of extraction chambers including straight bore, venturi, or sequential venturi, and are made of materials such as metal or glass. The extracted vapor may be collected in an inflatable bag, or inhaled directly through a hose or pipe. When used properly, cooler temperatures due to lack of combustion[3] result in significantly more efficient extraction of the ingredients. Hence, the irritating and harmful effects of smoking are heavily reduced,[4][5][6][7][8] as is its secondhand smoke.
