Most vaporizers work by separating the marijuana and the heating element with either a metal or glass plate and using air to heat the marijuana to it's vaporization point, releasing the THC and leaving the tar behind.
Different types of vaporizers use slightly different heating and delivery methods and can come in many different shapes and sizes, from small hand-held pipes to large table-top set-ups like the famous Volcano Vaporizer that use a balloon as the delivery method.
Several different scientific studies have been completed and found that vaporizers provide a much healthier delivery method for THC that smoking does.
In 2007, a study by University of California, San Francisco published in the Official Journal of the American Academy of Neurology examined the efficacy of a vaporizer that heats cannabis to a temperature between 180 °C (356 °F) and 200 °C (392 °F) degrees and found:
In 2006, a study performed by researchers at Leiden University, tested a vaporizer with preparations of pure THC and found that:Using CO as an indicator, there was virtually no exposure to harmful combustion products using the vaporizing device. Since it replicates smoking's efficiency at producing the desired THC effect using smaller amounts of the active ingredient as opposed to pill forms, this device has great potential for improving the therapeutic utility of THC.
