Vaping may be as harmful as smoking cigarettes, and it can trigger immune responses in lungs that cause deadly inflammatory diseases like Chronic Obstructive Pulmonary Disease (COPD) and cystic fibrosis, a new study published in the American Journal of Respiratory and Critical Care Medicine warns. E-cigarette users also exhibit significant increases in biomarkers of oxidative stress and activation of innate defense mechanisms associated with lung disease. So it’s dumb and dangerous.

Just say no to vaping. No, seriously. Please take that out of your mouth. Tom Lennon shows you just how stupid you look.
