about e-cigarette

In my opinion, e-cigarette is extremely great invention cause it will improve smokers health conditions and doesn't effect on people. The main problem of smoking is that it cause serious health problems such as myocardial infraction,asthma, lung cancer, and pneumonia. e-cigarette can solve this problem and I think it is great thing. However, not everybody agree with e-cigarette, the tabacco companies. Honestly speaking, selling tabacco can earn much more money than selling e-cigarette because e-cigarette can be used for a long time. Smokers can save money to nuse e-cigarette. Tabacco is massive industry all around the world. The new technology might crash exciting industry.
