About 150-180 million tobacco deaths would be avoided before 2050 if the proportion of adults in developing countries who quit smoking increases from below 5% today to 30-40% by 2020 (like current quit rates in Canada). Because control policies deter children from starting, even greater benefits can be expected beyond 2050.
如果发展中国家戒烟人口的比例从当今的5%不到提高到2020年的40%(正如加拿大目前的戒烟率)，那么，在2050年以前就可以避免大约一亿五千万到一亿八千万人死于吸烟。由于控制政策组织儿童开始吸烟，所以，人们可以预期在2050年以后将会有更大的收益。
