Passive smoking (second hand smoke) can jump start Chronic Obstructive Pulmonary Disease (COPD) among children. COPD is any disorder that restricts or obstructs bronchial airflow. In the case of COPD, the block is permanent and worsens over time.
Research suggests two ways of how COPD begins. “First is the common fast decline trajectory, where the function declines the normal level and the alternate trajectory where there is a suboptimal development of lung capacity among younger population. This suggests that the maximum capacity of lung function during childhood and adulthood is a major factor in determining risk of COPD.”
The full study can be found at the New England Journal of Medicine.
