I think e-cigarette is an good idea because it will not cause secondary smoke and decrease the victims of smoking. Since my father is a smoker, I want him to change tabacco into e-cigarette. But it won't be sold in Japan even though JT bought e-cigarette companies. I think it is strange, but I also think there are some reasons of it. I've read other students opinions and I agree some of them. Then, in my opinion, the biggest reason may be that e-cigarette will make it easy for people under 20 years old to approach the custom of smoking.
I've heard that it is very difficult for smokers to puite smoking and smoking cause kinds of diseases. Though I've never smoked, I can understand how hard it is to quite what I do in daily life. So I think JT should rethink whether they sell e-cigarette or not carefully even there are difficulties.
