25–45% of patients with COPD have never smoked

WHO estimates that 210 million people have COPD worldwide. COPD is the 4th leading cause of death in the world, but by 2030 it is expected to be the 3rd, behind CAD and stroke http://bit.ly/X5nje

25–45% of patients with COPD have never smoked http://bit.ly/3wAucF - 1 in 4 individuals will develop COPD during their lifetime (Lancet, 2011).

3 billion people, half the worldwide population, are exposed to smoke from biomass fuel compared with 1 billion smokers. Exposure to biomass smoke might be the biggest risk factor for COPD globally rather than cigarette smoke.

Different subsets of patients exist within the broad spectrum of COPD, targeted specific therapies could help http://bit.ly/3nuGuR
