The Practitioner’s Handbook serves as a comprehensive guide for external youth workers, offering practical recommendations and insights gathered from the experience of delivering the Chill Pill project. It provides valuable advice, strategies, and best practices for implementing peer-led well-being coaching, utilising the digital content creation toolkit, and engaging young people in promoting well-being and raising awareness about drug use. The handbook aims to support practitioners in effectively supporting youth in their well-being and mental health journey.
