Adolescence and young adulthood are periods of risk-taking and experimentation that often includes substance use. Schools and colleges are important settings in which to reach young people, although some vulnerable groups may not be well-represented within them.
In schools the focus is mainly on preventing or delaying the initiation of substance use and on the development of skills to support healthy decision-making.
Poor school attenders, frequent truants or young people with behavioural problems, such as poor impulse control, are at increased risk of developing problematic forms of substance use. This makes schools an important setting for early identification of at-risk individuals.
The greater independence of young people attending colleges and the tendency to increased alcohol and drug use in this age group make colleges an important setting for harm reduction and for referral of those developing problems to specialist services.
Of the interventions for which there is good evidence of effectiveness, smoking bans in schools are reported in all countries providing information, while 21 countries reported that school policies around substance use are in place in the majority of schools. Programmes aimed at developing personal and social skills are less widely implemented, with only 11 countries reporting them in the majority of schools. This is lower than the level of provision of information only programmes, which have not been found to be effective, but are reported in the majority of schools in 16 countries.
Some evidence exists in support of other types of programmes. Among these, peer-to-peer programmes seem to be relatively uncommon, but creative extracurricular activities and events for parents are more widely available. Drug testing of pupils is not recommended and is rarely used; it was only reported as being conducted in a few schools in 10 countries.
