Slang term for a vaporizer, which is used to smoke Marijuana, Tabacco and other smoking mixtures.
There are two different types of vaporizer. One kind heats the metal bowl in order to release the active ingredients, but at a low enough temperature that most toxins and carcinogens are not inhaled and the plant material is not burned. Another kind of vaporizer uses hot air to heat the herbs.
The vapor produced is inhaled.
Vaporizers are a very healthy alternitave to smoking, and reduce your intake of toxins greatly.
Johnny will go to a head shop tomorrow and buy a vape.
