Major outcome(s)Cannabis use is not associated with increased risks of respiratory diseases.

Cannabis use is not associated with increased risks of respiratory diseases. This is the conclusion of an analysis of 2304 participants, of whom 49% never used cannabis, 43% were former users and 8% were current cannabis users. Results by researchers of the Colorado School of Public Health, USA, were published in the journal Chronic Obstructive Pulmonary Diseases.
Neither current nor former cannabis use was associated with increased odds of wheeze, cough or chronic bronchitis when compared to never users. Current and former cannabis users had less emphysema and better forced expiratory volume in 1 second (FEV1%). However, heavy cannabis use was associated with more chronic bronchitis symptoms.
