Health literacy (including mental health literacy) is a valuable asset that can help a young person (or another involved  in their care) to determine what is required to live well and when help and treatment is best sought out. Resilience, constructive development and the resolution of substance use-related problems require the ability to direct attention and action strategically to meet needs and manage life stressors. This includes an ability to figure out when and how to use skills to bring a health issue under control.
