The Best Temperature For A Vaporizer Is ...

180-200 degrees Celsius, or 356-392 degrees Fahrenheit. So there. Now you know, and knowing is half the battle.

This information comes courtesy of TheAnswerPage.com, a medical education resource for physicians sponsored by The Massachusetts Medical Society. On Saturday, September 14, the site's "Question of the Day" involved "vaporization — a smokeless delivery system used for cannabis inhalation. Vaporization uses warm air or heat of 180°C to 200°C, rather than a flame, to convert cannabinoids and other compounds found in herbal cannabis into a fine mist that can be inhaled. Since temperatures are far lower, no combustion by-products such as soot or polycyclic aromatic hydrocarbons are produced. Due to their volatility, cannabinoids will vaporize at temperatures of 180°C to 200°C, but will not combust at these temperatures."

The gold standard in vaporizers is the toaster-sized Volcano Vaporizer made by German company Storz and Bickel. But variations on the device are endless and some vaporizers are the size of a Bic pen.

Some people say vaporization doesn't produce as big an effect as smoking pot, but studies disagree.

"In 2007, Abrams et al. published an article entitled 'Vaporization as a smokeless cannabis delivery system: A pilot study' in the Journal of Clinical Pharmacology and Therapeutics. In this pilot study, Abrams et al. administered either smoked or vaporized cannabis of 3 different strengths to 18 healthy subjects. While vaporizing resulted in higher plasma concentrations of THC compared to smoking cannabis at 30 and 60 min at each strength, there was no significant difference between smoking and vaporizing in the 6-hour area under the plasma THC concentration—time curve (AUC). This data implies that drug absorption across the alveolar membrane is faster with vaporization as compared with smoking, but as time elapses the phytocannabinoid plasma concentrations equalize."

In a double-blind, placebo-controlled, crossover study of thirty-nine patients with central and peripheral neuropathic pain from spinal cord injury, complex regional pain syndrome (CRPS I and II), multiple sclerosis, postherpetic neuralgia, brachial plexopathy and lumbosacral radiculopathy, vaporized cannabis reduced pain by 30 percent compared to placebo. Pot worked on more people's pain than two anticonvulsants commonly used to treat neuropathic pain, theAnswerPage notes.
