E-cigarette use has become popular only recently, and studies investigating the dangers are ongoing. What we know so far shows vape use is far from safe. One preliminary study conducted with newborn mice found that exposing the mice to e-cigarette smoke resulted in slightly smaller lungs, decreased cell growth, and a lower body weight than mice who had not been exposed.6
Another study found that exposing mice to e-cigarette smoke containing nicotine contributed to symptoms normally exhibited in the development of chronic lung disease.7

Studies done with human lung cells and the cells of airway passages have also begun to show the negative effects of e-cigarettes. When the cells were incubated with e-cigarette smoke, there was an increase in cell death, an increase in the production of substances that cause harmful inflammation, and weaker defense against bacterial infections, along with what may have been cancerous characteristics.
Vape and vape mods have also exploded. Vape battery explosions have killed, and serious third and second degree burns can result in scarring, nerve damage, and the need for skin grafts.
