EFFECTS

The health risks of e-cigarettes are uncertain. They are likely safer than tobacco cigarettes, but the long-term health effects are not known. E-cigarettes can help some smokers quit. When used by non-smokers, e-cigarettes can lead to nicotine addiction. So far, no serious adverse effects have been reported in trials. Less serious adverse effects include throat and mouth irritation, vomiting, nausea, and coughing.
