Smoking cessation brings immediate health benefits at any age, whether or not smoking-related disease is present. Stopping smoking decreases the risk of lung and other cancers, heart attack, stroke and chronic disease compared with continued smoking.27 Quitting by the age of 30 may reduce disease risk almost to that of a never smoker, and quitting smoking at the age of 50 approximately halves the risk of dying from tobacco-caused disease.2 In heavy smokers, cutting down on the amount smoked instead of quitting completely does not appear to offer a health advantage. Research has shown that even if heavy smokers more than halve their consumption, they may not substantially reduce their risk of dying from smoking-caused cancer or cardiovascular disease.239 The health benefits of cessation are discussed in detail in Chapter 7, Section 7.2.
