How beneficial is vaping cannabis to respiratory health compared to smoking?

Addiction. 2015 Nov;110(11):1706-7. doi: 10.1111/add.13075.


While vaping cannabis reduces respiratory exposure to toxic particulates in cannabis smoke, the resultant reduction in clinically evident harms to lung health is probably smaller than that likely to result from substituting e-cigarettes for smoked tobacco due to the comparatively greater harms of tobacco than cannabis smoking to lung health.

Keywords: Cannabis; chronic bronchitis; e-cigarettes; lung injury; respiratory health; vaping.
