Vaporize me!

A study by NORML and the Multidisciplinary Association for Psychedelic Studies showed that a “vaporizer” can reduce harmful toxins in pot smoke.
The study, released in January, found that cannabis gave off THC at 185?C (365?F), with no measurable level of benzene, toluene or naphthalene. Carbon monoxide and smoke tars were also reduced by the vaporizer. Benzene began to appear around 200?C (392?F), while full combustion occurred at 230?C (446?F).
