THE FUTURE WORLDWIDE HEALTH EFFECTS OF CURRENT SMOKING PATTERNS<br />

the risk of death from tobacco in middle or old age is really substantial (about 1 in 2)<br />

only for those who start smoking in early adult life (Doll <strong>and</strong> Peto 1981; Peto et al.<br />

1986, 1994; Doll et al. 1994, 2004). Hence, when there is a large upsurge in cigarette<br />

smoking among the young adults in a particular country, this will produce a large<br />

upsurge in tobacco deaths half a century later; the numbers of deaths from tobacco<br />

around the year 2000 were strongly influenced by the numbers of young adults who<br />

took up smoking around 1950, while the numbers of young adults who took up smoking<br />

around the year 2000 will strongly influence the numbers of deaths from tobacco<br />

around the year 2050 (<strong>and</strong> beyond).<br />

The main increase in cigarette use by young adults took place during the first<br />

half of the twentieth century for men in developed countries, but it took place<br />

during the second half of the century for women in developed countries <strong>and</strong> for men<br />

in developing countries (Doll et al. 1994; Peto et al. 1994; World <strong>Health</strong> Organization<br />

1997). Thus far, relatively few women in developing countries have begun to smoke.<br />

For men in developed countries the epidemic of tobacco deaths may already be<br />

about as large as it will ever be, with tobacco now responsible for about one-third of all<br />

male deaths in middle age (Peto et al. 1994). Continuing increases in male tobacco<br />

deaths in developed countries such as Greece or Portugal are offset by recent decreases<br />

elsewhere, e.g., the UK. For women in most developed countries, however, the epidemic<br />

still has far to go—indeed, in many European countries such as France or Spain the<br />

main increase in tobacco deaths is only just beginning, although in the United States<br />

the proportion of deaths in middle age that is due to tobacco is now almost as great in<br />

women as in men (Peto et al. 1994).<br />

In North America, taking both sexes together, US cigarette consumption per adult<br />

was 1, 4, <strong>and</strong> 10 per day in 1910, 1930, <strong>and</strong> 1950, after which it remained relatively<br />

constant for some decades. As a delayed result of this pre-1950 increase in cigarette<br />

consumption, the proportion of all US deaths at ages 35–69 attributed to tobacco rose<br />

from 12% in 1950 to 33% in 1990 (Peto et al. 1994).<br />

In China, which is the largest <strong>and</strong> best studied of the developing countries (Liu et al.<br />

1998; Niu et al. 1998; Peto et al. 1999), the increase in male cigarette consumption <strong>and</strong><br />

in tobacco deaths both lag almost exactly 40 years behind the US. At present, few of<br />

the young women in China become smokers, but adult Chinese male cigarette consumption<br />

averaged 1, 4, <strong>and</strong> 10 per day in 1952, 1972, <strong>and</strong> 1992, with no further<br />

increase during the past few years, <strong>and</strong> the proportion of Chinese male deaths at ages<br />

35–69 attributed to tobacco was measured to be 12% in 1990 <strong>and</strong> is projected to be<br />

about 33% in 2030. Two-thirds of the young men in China become persistent smokers,<br />

<strong>and</strong> about half of those who do so will eventually be killed by the habit: so, about onethird<br />

of all the young men in China will eventually be killed by tobacco, if current<br />

smoking patterns persist.<br />

China, with 20 per cent of the world’s population, produces <strong>and</strong> consumes about<br />

30% of the world’s cigarettes, <strong>and</strong> a large nationwide study has now shown that China
