It's supposed to be an alternative to what some people call a dirty habit and now the government intends to regulate it.
If the FDA has its way, electronic cigarettes, commonly known as e-cigarettes, could be classified as a tobacco product and treated as such in public places.
Critics of e-cigarettes are skeptical of the effects of the vapor that inhaled by users, saying that its effects are not totally understood.
"It helps the environment, you can 'vap' inside, you can 'vap' in restaurants, it's healthier, you only have four ingredients in these whereas cigarettes have a ton of stuff in them," said John Connolly, the owner of Vapin in the Valley.
So far, it's not clear when the FDA plans to propose those regulations.
