Inhaling vaporized cannabis does not improve breathlessness or exercise endurance in patients with advanced chronic obstructive pulmonary disease (COPD), according to a small Canadian study.
The study reporting the findings, “Effect of vaporized cannabis on exertional breathlessness and exercise endurance in advanced COPD: A randomized controlled trial,” was published in the journal Annals of the American Thoracic Society.
COPD is an inflammatory disease that affects the lungs, and dyspnea or breathlessness is one of the main clinical symptoms of the disease.
It is estimated that more than 40% of COPD patients experience breathlessness during minimal or no activity. Easing breathlessness in these patients could improve their quality of life.

Now, researchers assessed the potential effect of inhaled vaporized cannabis in easing breathlessness in patients with advanced ... read more at: https://copdnewstoday.com/2018/07/31/inhaled-vaporized-cannabis-failed-improve-copd-symptoms-clinical-trial/
