Health Risks of E-cigarettes

E-cigarettes are still fairly new, and more research is needed over a longer period of time to know what the long-term effects may be.

So far, research has found that e-cigarette use is likely to be significantly less harmful than smoking regular cigarettes. This is because e-cigarettes do not burn tobacco, a process that produces an estimated 7,000 chemicals, including at least 70 chemicals that cause cancer. But, the health effects of long-term use are not known.
