Several factors are thought to predict or increase the chance of developing nicotine dependence. For example, people who start smoking at an early age are more likely to become dependent smokers than those who start later in life.1 Dependence is also more likely among some ethnicities.2

Individuals may vary in genetic vulnerability for developing nicotine dependence. For instance, individual variation in the CYP2A6 enzyme responsible for metabolising nicotine correlates with smoking rates,3 while dependence on other drugs is also highly correlated with nicotine dependence.4 In addition, mood, anxiety, and personality disorders are also associated with significantly increased risk of nicotine dependence.5, 6 One US study of smokers found that nicotine dependence is more likely for women, adults younger than 65 years, those with less education, or unmarried adults.7
