Using a cannabis vaporizer continues to grow in popularity as the one of the healthiest ways of consuming cannabis as a medicine. Vaporizers heat cannabis to a carefully controlled temperature, at which the active substances (THC and other cannabinoids) turn into vapour. Since vapour is not the product of burning, it contains no carbon or semi-burned solid material, and thus produces much less tar.
Cannabis vapour is inhaled in the same way as smoke, but without the unhealthy side effects of smoking. Because the THC is released without burning, none of it is lost to overheating (as happens when cannabis is smoked) allowing a given amount of cannabis to be consumed much more efficiently. The ability to use less cannabis to achieve the same effect also makes buying a cannabis vaporizer a sound economic choice.
