Alcohol and other drugs (AOD) is one of the four core streams that guides holistic care provided to all young people who access a headspace service. Research demonstrates a clear bi-directional relationship between mental ill-health and substance use for many young people. With this in mind, headspace has developed a National Alcohol and Other Drug strategy to support our workforce across the headspace network, and to guide our priorities when working with young people who use AOD as well as addressing barriers that a young person may experience when seeking support around their substance use or mental health. The strategy also guides our broader principles, practices and positions in relation to AOD. This presentation will outline the background to the development of the strategy, the sharing of the strategy as well as our priorities and considerations when implementing the strategy.
