Many vaporizer users cite the health benefits as the main reason they prefer it over smoking. For medicinal marijuana patients, who may have weakened respiratory systems that are bothered by the toxins and impurities, the extremely clean and active vapor produced by vaporizers is especially appreciated. Not only is vapor cooler than smoke and cleaner it is also more efficient than combustion methods and can deliver equivalent doses with far less total plant matter. Used correctly vaporization significantly reduces the amounts of tar and many other dangerous compounds inhaled while maintaining or even increasing the delivery of therapeutic compounds. This aspect of vaporization is a great benefit for many people, particularly individuals who have trouble eating, swallowing, or digesting food.

Medicinal marijuana is quickly gaining acceptance for its therapeutic benefits both in the Unites States and around the world. Before cannabis was effectively outlawed in 1937 by the government it was one of the most widely used medicines. Now that research funding is again supporting exploration of marijuana and the active compounds in THC the number of its known medical uses is rapidly growing. Marijuana is one of the most effective known cures for nausea and is also a fantastic appetite stimulant. These two characteristics combine to make cannabis a perfect solution for patients who have diseases or even treatments that cause weight loss and suppress appetite. Patients who experience extreme nausea are sometimes prevented from taking pills to help relieve their symptoms because of the their inability to swallow anything. Cannabis however can be vaporized and inhaled and so can provide relief even for the most extreme sufferers of nausea.

Cannabis is one of the least toxic substances, in the thousands of years it has been in use there are no known records or accounts of lethal overdoses of THC. The most harmful aspect of THC ingestion is the inactive plant matter that is incidentally combusted along with the desired therapeutic compounds. Eating foods prepared with cannabis infused products is an alternative delivery method that avoids the lung danger of smoking but dosages can be difficult to determine because of the cooking process. Vaporizers are able to effectively deliver measured doses with minimal health risks and remove the last obstacles for the widespread use of medicinal cannabis.
