Health and Medicinal Use

Regardless of the benefits of medical cannabis, the widely perceived health risks of smoking as a route of administration have been viewed as a major obstacle for the legal approval of cannabis for medical uses, though some studies indicate that the expectorant activity of THC may help the lungs remove much of the inhaled tar through coughing.

In response to the concerns, several studies have aimed to establish whether or not vaporizers could offer a clinically reliable and safe route of administration for cannabis.

Though vaporizers show great variations in performance, such studies have consistently found vaporization superior to smoking and with best case (high-end vaporizers used with potent cannabis) results showing an elimination of undesired compounds suitable for clinical trials. In comparison to other routes of administering cannabis such as eating, vaporization offers the advantages of inhalation - immediate delivery into the bloodstream, rapid onset of effect, and more precise titration, the ability to more accurately control the dosage to produce a desired effect.
