“Enjoy!” says N-Joy to all the cigarette smokers. The company currently markets the e-cigarette that does not contain any tobacco or other harmful carcinogens that are normally associated with the regular cancer causing stick. The new e-cigarettes will also allow the smokers to have a smoke even on airplanes and in some restaurants.

"People that smoke today, they're gonna smoke because they like to smoke. Unfortunately, 5 million of them die from the current cigarette they smoke, this is an alternative to that," says John Wiesehan, the president of the company that distributes the e-cigarettes.

However, scientists are still skeptical about the safety quotient of these e-cigarettes.

"We do not know what is in it, we do not know if when what is in it is brought into the lungs repeatedly, it is safe for the lungs," says Dr. Cheryl Healton, President of the American Legacy Foundation.

The FDA says that e-cigarettes are not approved for marketing in the U.S. and they are looking at each product on a case by case basis. They have not yet been reviewed for safety and effectiveness.

A Florida-based e-cigarette manufacturer is currently seeking a restraining order against the FDA, claiming that the agency does not have any authority to regulate its products.

At the start an e-cigarette could cost its user approximately $150 while the refill cartridges would cost roughly $20.
