The document discusses drug, alcohol, and substance abuse among young people in London and the UK. It notes that drug use results in high costs to the London Ambulance Service and police. While most schools provide drug education once a year or less, proven programs like Life Skills Training that are implemented in US schools have been shown to reduce substance abuse and have a cost benefit ratio of $25 saved for every $1 invested. The document calls for increased funding for early intervention and prevention programs in schools to address substance abuse among youth.
