According to new data published in the journal PLOS ONE, vaporizers are not only effective in delivering cannabinoids to medical marijuana patients, but they also do so in a safe and reliable manner. Swiss investigators analyzed the ability of different types of vaporizes to release THC and CBD through vapor, and reported the technologies allowed for relatively safe and uniform dosing. They also reported gas-powered devices were unreliable and not recommended for therapeutic purposes.
Because vaporizers are temperature controlled, they are able to heat cannabis to a point where vapors form but do not reach the point of combustion. Therefore, the authors conclude, "[T]he four electrically-driven and temperature-controlled vaporizers investigated in this study efficiently decarboxylate acidic cannabinoids and release reliably the corresponding neutral cannabinoids into the vapor. Therefore, they can be considered a promising application mode for the safe and efficient administration of medicinal cannabis and cannabinoids."
