W: I hate walking into our building in the morning! All the smokers stand around the building’s entrance puffing away. I can’t take it!
M: That’s OK. I understand. A lot of people really hate smoke.
W: I’m glad they banned smoking inside the office, but I wish I didn’t have to smell it while walking on the street. I simply can’t understand why a person would want to smoke.
M: Well. I used to smoke, but I quit about 20 years ago.
W: Yeah. I would assume at this point in history especially given what we know about the dangers of smoking most people would have quit already!
M: You know the saying, "Old habits die hard. " I think I would add that "Bad habits die even harder." You know, you could always move to Bhutan.
W: Bhutan? I don’t think I’ve ever heard of it.
M: It’s a small kingdom located in the Himalayan Mountains (喜马拉雅山脉) near Nepal. In 2004, Bhutan banned tobacco altogether.
W: Cool! Did it work? If I go to Bhutan, will I never smell cigarette smoke?
M: Actually, no. I read a recent report that said there are a lot of loopholes (漏洞) in the law, and if you go to restaurants and bars, you’ll still see lots of people lighting up.
W: So I guess I just have to learn to put up with it.
M: Things are changing, however. Smoking rates are dropping all around the world. Just the other day, there was a newspaper report that said New Zealand is raising prices on a pack of cigarettes to $20 by the year 2025!
W: $20? Wow! That’s really expensive. But is there any proof that high prices work?
M: There have been quite a few studies that show that every time a country raises cigarette taxes and prices, a certain percentage of smokers quit.
W: I see. The high prices act as the straw (稻草) that broke the camel’s back. Smokers that have been meaning to quit see the price increase, and it gives them a little push.
M: Yeah. But on the other hand, prices are already quite high in many places. A pack of cigarettes in London costs about $ 10, in New York a pack costs roughly $8, and in Norway it’s already around $14. But I was in London not that long ago. I saw plenty of smokers!
W: Yeah. The last time I was in New York, there also seemed to be plenty of smokers. I guess there are some people who are wealthy enough to afford whatever price.
M: Definitely. I think the best way forward is to push education efforts for young people. If we can convince the next generation that smoking isn’t cool, eventually we might be able to eradicate (根除，消灭) smoking.
