Are There Any Second Hand Effect from Electric Cigarettes?

logo1267406_mdA new study published in Nicotine and Tobacco Research concluded that electronic cigarettes used indoors may involuntarily expose non-users to nicotine.

When users take a puff , a nicotine solution is heated, and the vapor is taken into the lungs. Researchers examined the vapor from 3 different brands of e-cigarettes using a smoking machine in controlled exposure conditions. They also compared secondhand smoke exposure from e-cigarette vapor and tobacco smoke generated by dual users.

Results showed that e-cigarettes emit significant amounts of nicotine, but not much carbon monoxide and toxic volatile organic compounds. The amount of secondhand nicotine varied by the brand and were lower than that produced by conventional tobacco cigarettes. The U.S., Surgeon General found no safe level of secondhand smoke from tobacco but has not evaluated the health risk of secondhand risk of cigarette vapor.

Researchers believe this is one of the few studies on secondhand risk of e=cigarettes and said the exposure to nicotine is 10 tiumes less than from tobacco smoke. However, additional research is needed to evaluate effects of secondhand smoke of e-cigarette vapors on vulnerable populations such as pregnant women and children and the effect on the smokers themselves.
