Butane vaporizers are a type of vaporizer that uses a butane flame as the primary source of heat. Vaporizers are devices capable of extracting the cannabinoids and terpenes contained in your herbs, without actually burning them. They produce just enough heat to reach the boiling point of these compounds, that will eventually boil, releasing the vapour. While traditional vaporizers work with a battery and a small electricity-operated oven, butane vaporizers rely on a much more powerful source of heat to create vapour: a butane-powered jet lighter such as this one.
