Marijuana Use, Respiratory Symptoms, and Pulmonary Function: A Systematic Review and Meta-analysis

The health effects of smoking marijuana are not well-understood.  The purpose of this systematic review is to examine the association between marijuana use and respiratory symptoms, pulmonary function, and obstructive lung disease among adolescents and adults.  

Low-strength evidence suggests that smoking marijuana is associated with cough, sputum production, and wheezing. Evidence on the association between marijuana use and obstructive lung disease and pulmonary function is insufficient.
