Early tobacco exposure may cause chronic lung disease in adulthood.


Everyone knows cigarettes are bad, right? Of course you do. We’ve been told over and over again that tobacco use is not only bad for your health but secondhand smoke and chemicals lingering in fabrics such as clothes, furniture, and upholstery can create unhealthy conditions for non-smokers, too.

But just how bad is it, really?

New studies released by International Journal of Chronic Obstructive Pulmonary Disease found that second-hand tobacco exposure to unborn children and young children may significantly raise the risk of developing Chronic Obstructive Pulmonary Disease (COPD).

Environmental tobacco exposure also showed negative impacts on children’s lung function, but there wasn’t enough evidence to correlate that type of exposure with future development of COPD.

Tobacco wasn’t the only study performed to test for possible indicators of future COPD development. In total, sixteen studies involving more than 69,000 people were conducted.

Those studies found that low birth weight, preterm birth, and respiratory diseases, primarily asthma and pneumonia, in early childhood are also associated with lung function impairment later in childhood, and by that predispose to subsequent development of COPD.
