Scotland has a considerable number of young smokers, with 15-year-olds in particular having the highest rate of smoking in Europe. According to the Scottish Schools Adolescent Lifestyle and Substance Use Survey, 15% of 15-year-olds smoke at least one cigarette a week.

Rates of smoking may be due to a range of factors, including peer pressure, weight management and the perceived attractiveness of smoking. Girls may be more concerned about their weight, and weight gain may play a role in higher smoking rates among girls.

Many young people whose parents or carers smoke may also consider smoking to be 'normal' behaviour. Evidence has shown that young people who are brought up in a smoking household are more likely to become smokers themselves.

Young smokers can have marked differences in their smoking behaviour compared to adults, with more irregular smoking patterns. However, those who do smoke daily are at particular risk of becoming addicted and will find giving up more difficult.

Research has shown that the prevalence of smoking among looked after and accommodated children and young people is very high compared to their peers – 75% of young people in residential units smoke – and health professionals should consider how they can best support these groups.

Smoking is particularly harmful to young people, as tobacco smoke is more likely to cause chest infections, asthma, and middle ear disease in those whose lungs, airways and immune systems are still developing.
