Being against with tobacco fans is obvious risks, but e-cigarette is turn to be a big challenge for Tobacco.

e-cigarettes were saled about $500m in America, compared with the $80 billion market tobacco,it is a very small number, But e-cigarette will sales doubled in the next year, sales of e-cigarettes could overtake sales of the normal sort within a decade.

In America and Britain advertisements for e-cigarettes have appeared on television—forbidden territory for standard cigarettes. Craig Weiss, the head of NJOY, America’s top-selling brand of e-cigarettes, vows to make traditional ones obsolete. His ads crow: “Cigarettes, you’ve met your match.”

America’s tobacco giants do not think he is blowing smoke. Last year Lorillard (the maker of brands such as Newport and Kent) bought Blu, an e-cigarette maker, for $135m. NJOY is rumoured to be facing a takeover, perhaps by Altria (the maker of Marlboro). Foreign cigarette makers, such as British American Tobacco and Japan Tobacco International, also have stakes in the industry, while other firms are working on their own vaporous offerings.
