Abstract:
Marijuana is the most widely usedillegal drug in the world, with a prevalence of 2.5%-5%, and the second most commonly smoked substance after tobacco. The components of smoke from combustion of marijuana are similar to those produced by the combustion of tobacco, but they differ in terms of psychoactive components and use. Inhalation of cannabis smoke affects the respiratory tract, so the available evidence must be updated in order to provide pulmonologists with the latest scientific information. In this article, we review the impact of cannabis consumption on the lungs, taking into account that the respiratory route is the most popular route of cannabis consumption.
