Most smokers become addicted in their teenage years1 and most Australian teenagers who become smokers obtain their first cigarette from a friend or an acquaintance.2, 3 Smoking prevalence escalates rapidly during adolescence, from 2% of 12-year-olds to 18% of 17-year-olds among Australian teenagers in 2005. Fewer than 10% of 17-year-old current[1] and daily smokers say that they definitely intend to quit smoking in the future. This strongly suggests that most Australian students who smoked in their final year of school in 2005 will continue smoking beyond their school years.2
Young people can become addicted to cigarettes at very low consumption levels, and after smoking only a few cigarettes.4 British research has found that smoking just a single cigarette at the age of 11 can leave a child susceptible to later uptake of regular smoking, even after a period of three or more years. This could be due to neurobiological factors, or social or personal traits.5
The first 18 sections of this chapter provide discussion about stages in the uptake of smoking, and the range of factors that influence an individual's decision whether or not to start smoking. While the various threads are discussed separately, it is important to remember that in reality many of these factors are interconnected and should not be considered in isolation. The second part of this chapter, commencing with Section 5.19, examines ways of countering these influences to help prevent the uptake of smoking.
