At this time, we do not know if e-cigarettes are safer than cigarettes. Before the current outbreak of vaping-linked lung injuries, scientific studies suggested that people who completely switched from smoking to using electronic cigarettes would be exposed to fewer harmful chemicals. But the outbreak highlights that there is still a lot we do not know about e-cigarettes and vapor products. We also do not know the long-term effects of vaping, because these products have not been around long enough to study what they might do to long-term health.
E-cigarettes have not been proven to be effective tobacco cessation aids. Adults who use e-cigarettes, vapor products or other tobacco products and are attempting to quit should use evidence-based treatments, including counseling and FDA-approved medications.
