A vaporizer or ‘vape’ is a device used to vaporize the active ingredients of plant material for the purpose of inhalation. They can also be filled with a mixture of propylene glycol, glycerin, and nicotine. (e.g. tobacco-free nicotine). Vaporizers can 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 more efficient extraction of ingredients, and reduce the irritating and harmful effects of traditional smoking.
