"We don't know how much nicotine is exactly there. We don't know how much is being delivered. We don't know the content of the vapor. This has not been studied" - Doctor Johnathan Whiteson from New York University's Cardiac and Pulmonary Wellness and Rehabilitation Program on the CBS Morning Show 02/27/09
