Book excerpt: "Parenting is hard. If you are reading this, you are likely a very concerned parent who is looking for guidance about how to help your child who is using substances (or engaging in other risky behaviors). You may have mild concerns about your child's focus at school, choice of friends, new "minimalist" communication style with you, or you may be facing sudden and terrifying changes. Whatever your particular mix of worries as a parent, your child's drug use (including alcohol) tends to make it that much more nerve-racking--sometimes explosive." From introduction, page 1.
