A volcano vaporizer is a machine that is shaped like, well a volcano, and uses heated volcano-vaporizer-smokeforced air to vaporize the active compounds in plant matter and expel the resulting vapor into a bag. The bag then holds the vapor which can be inhaled directly from the bag at the leisure of the smoker. One of the primary  benefits of this type of vaporizer is that it can be finely adjusted to heat plants or herbs to precise temperatures. This allows for only desired compounds to be vaporized and ingested.

Much of the harshness of smoking is due to the burning of plant matter which contains the impurities and toxins vaporization avoids. Because vaporization is a healthier and gentler delivery method many medical marijuana patients utilize the method. The Volcano Vaporizer is a brand name device manufactured by Storz & Bickle, a German company, though the term is becoming synonymous with upright vaporizers that utilize hot air convection.

Volcano vaporizers are known for their efficiency in vaporizing active compounds with little unwanted plant matter or toxins. Many  happy users will quickly provide stories and descriptions of their experiences with vaporizers if asked. However, volcano vaporizers have undergone more than just casual testing on couches around the world. There has been several recent studies which examined the volcano vaporizer and its suitability as a THC delivery system for ailing patients. These studies have all produced evidence supporting vaporization as one of the best and easiest methods for medicinal ingestion. In a controlled setting the volcano vaporizer was found to produce vapor with far less harmful substances than combusted smoke.

If you are considering vaporization it is now easier to get started than ever. Many modern vaporizers, including the Volcano, come with digital control mechanisms which makes precise control easy. With the ability to set the heat to precise temperatures volcanoes can be used to with a variety of different herbs and plants for medicinal purpose, aromatherapy, or recreation.
