While drug use prevalence has remained stable between 2013 and 2015, with the exception of 15 year old boys, there appears to have been an increase in the availability of drugs since the last wave of the survey. There have been increases in the proportion of pupils who have been offered drugs and the proportion who say they would find it easy to obtain drugs if they wanted to.
Drug use in the last month has been gradually decreasing since 2002. However, between 2013 and 2015 there has been a small increase in the proportion of 15 year old boys who took drugs in the month prior to the survey. Drug use among 13 year olds and 15 year old girls has remained stable.
