世界上有多少人公开谈论过吸烟的危害性?这是无法统计的。在某些国家里,为了反对吸烟,开展了声势浩大的社会运动,广泛地利用新闻机构大力宣传并采取了各种各样的措施予以禁止和限制。然而尽管如此,许多人依然我行我素,继续吸烟。为什么会发生这样的事情呢?他们损害自己的健康,未必只是由于固执己见。正如伦敦很有权威的医学杂志World Medicine所认为的那样,情况是非常复杂的。 How many people in the world openly talked about the dangers of smoking? This is not statistically significant. In some countries, in order to combat smoking, there has been a massive social campaign and extensive use of news agencies to vigorously promote and take various measures to prohibit and restrict it. However, many people still go its own way and continue to smoke. Why does such a thing happen? They harm their own health, not necessarily because of their own opinion. As World Medicine, the authoritative medical journal in London, believes the situation is complex.
