Because they contain no tobacco, e-cigarettes aren't subject to U.S. tobacco laws, which means they can be purchased without proof of age, especially online. This raises concerns that e-cigs may be particularly appealing to kids and may encourage nicotine addiction among young people. And while manufacturers of the e-cigarette claim that it's the cigarette you can "smoke" anywhere, regulatory agencies around the world are taking a close look at these gadgets and instituting a range of restrictions on their use.
I think major part of e Cigarette user are actual smokers, and very less part are youngster who use E Cig and among them some are divert from e cigarette to real cigarette. So, It will indirectly help to major part of smokers to quit smoking.
