By heating the cannabis at a lower temperature than combustion, the devices produce a vapor that still contains the active medical ingredients in cannabis (cannabinoids), but without the harmful by-products. Vaporizers efficiently convert the whole plant matter into active cannabinoids needed for the patient.

Another advantage is that vaporizers ranked highest in side effect satisfaction by patients, meaning that they felt most functional after vaporizing cannabis. This is likley because the product is inhaled is stricly vapor and does not produce any smoke.
