Vaporizer (inhalation device)

A vaporizer or vaporiser is a device used to vaporize the active ingredients of plant material, commonly cannabis, tobacco, or other herbs or blends for the purpose of inhalation. However, they can also be filled with a mixture of propylene glycol, glycerin, and nicotine. (e.g. tobacco-free nicotine).

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 result in significantly more efficient extraction of the ingredients. Hence, the irritating and harmful effects of smoking are heavily reduced, as is secondhand smoke.

An electronic cigarette is a battery-powered vaporizer which simulates the feeling of smoking, but without burning tobacco. The three main types of e-cigarettes are cigalikes, eGos, and MODs. Their use is commonly called "vaping". The user activates the e-cigarette by taking a puff or pressing a button. They are often cylindrical, but come in many variations. Some look like traditional cigarettes. Most are reusable but there are also disposable versions called first generation cigalikes. There are also second, third, and fourth generation devices. Instead of cigarette smoke, the user inhales an aerosol, commonly called vapor. E-cigarettes typically have a heating element that atomizes a liquid solution known as e-liquid. E-liquids usually contain propylene glycol, glycerin, water, nicotine, and flavorings. E-liquids are also sold without propylene glycol, without nicotine, or without flavors.
