Launched 13 years ago by Strathclyde Police, but run since 2005 as a national event by the Scottish Crime and Drug Enforcement Agency, the show has been attended by more than 250,000 pupils since it started.
The programme, funded by the Scottish Government, provides information and guidance to help upper primary pupils resist peer pressure and illustrates the benefits of choosing a healthy lifestyle free from harmful substances, including tobacco, alcohol and illegal drugs.
A number of performers are again taking part in the event, including television's Any Dream Will Do runner-up Keith Jack, X-Factor finalists the MacDonald Brothers, dance act Karen Danzig and PACE theatre group.
Detective Superintendent Willie MacColl, the SCDEA's national drugs co- ordinator, said: "Choices for Life is an integral part of our interventions approach to tackling drugs misuse in Scotland. Through our enforcement role, we can tackle the supply of drugs by arresting drug dealers and removing their commodities from the street, Likewise, we can enforce measures to control the supply of alcohol to those who are under- age. However, if we want to have a long-term impact on these issues, education is vital to reducing the demand for these substances."
Teachers' support materials are available, created in partnership with Learning and Teaching Scotland.
