The commentaries by the two former tobacco industry consultants, university professors at a major midwestern medical school, are not in any way pro-tobacco, although they do criticize a number of current anti-smoking initiatives because they are ineffective and not based on sound formative research.

But other health academics have disagreed and have written to the World Health Organisation describing e-cigarettes as potentially life-saving.

The problem with e-cigarette experimentation, for the prospects of cigarette smoking initiation, is that youth are getting used to sweet and flavored products. It is going to be extremely difficult to go from the sweet and flavored taste of the electronic cigarette to the harsh taste of a tobacco cigarette. That transition is not favored, at least not on a theoretical basis. Why would a youth switch from a cherry e-cigarette to a Marlboro?
