Vaporization is a technique for avoiding irritating respiratory toxins in marijuana smoke by heating cannabis to a temperature where the psychoactive ingredients evaporate without causing combustion.
Laboratory studies by California NORML and MAPS have found that vaporizers can efficiently deliver cannabinoids while eliminating or drastically reducing other smoke toxins.
Like tobacco, marijuana smoke contains toxins that are known to be hazardous to the respiratory system. Among them are the highly carcinogenic polynuclear aromatic hydrocarbons, a prime suspect in cigarette-related cancers.
These toxins are essentially a byproduct of combustion, separate from the pharmaceutically active components of marijuana, known as cannabinoids, which include THC.
Although there is no proof that marijuana smoking causes cancer, chronic pot smokers have been shown to suffer an elevated risk of bronchitis and respiratory infections. Respiratory disease due to smoking may therefore rightly be regarded as the primary physiological hazard of marijuana.
Cannabis vaporizers are designed to let users inhale active cannabinoids while avoiding harmful smoke toxins. They do so by heating cannabis to a temperature of 180 - 200° C (356° - 392° F), just below the point of combustion where smoke is produced.
At this point, THC and other medically active cannabinoids are emitted with little or none of the carcinogenic tars and noxious gases found in smoke. Many medical marijuana patients who find smoked marijuana highly irritating report effective relief inhaling through vaporizers.
Users who are concerned about the respiratory hazards of smoking are strongly advised to use vaporizers. Alternative devices, such as waterpipes, have been shown to be ineffective at reducing the tars in marijuana smoke

December 2013 - Spurred by growing reports of the medical efficacy of cannabidiol (CBD), the second leading active ingredient in marijuana, patients are increasingly seeking out high-CBD varieties for treatment of conditions ranging from severe epilepsy and multiple sclerosis to anxiety and cancer pain.
CBD has long been overshadowed by delta-9-THC (tetrahydrocannabinol), the primary active ingredient in marijuana, because unlike THC, it does not produce a psychoactive ?high.? CBD has nonetheless long been known to have useful anti-spasmodic, anti-epileptic, anti-anxiety, and anti-psychotic properties.
Although CBD lacks noticeable effects when taken alone, it has a calming, sedative effect when combined with THC, cutting down on the anxiety, paranoia, and memory impairment that many users find unpleasant or debilitating with regular marijuana. CBD-rich strains accordingly have particular appeal to older users and medical patients who are uncomfortable with the THC high.
Public interest in CBD was aroused by a recent CNN report on medical marijuana by Dr. Sanjay Gupta. Previously a skeptic on medical marijuana, Dr. Gupta admitted to having been ?brainwashed? by government propaganda.
Gupta featured the story of a 5-year-old girl, Charlotte Figi, who suffered continual epileptic seizures from a rare disease known as Dravet?s syndrome. Conventional treatment having failed, Charlotte?s condition dramatically improved after she was treated orally with an extract of CBD-rich cannabis.
