In the UK, changes to drug and alcohol policy post-1995 introduced the partnership style of working and many different routes by which treatment can be accessed. This means that a wide variety of professional groups now work with drug and alcohol users. This book provides an analytical and critical discussion of policy and practice in this area. It lays out the key debates and issues for understanding, exploring, dealing, and working with substance misuse issues, users, their families, and other professionals. The reader is introduced to the UK's policy framework and why it is important for generic social work and other health and social care practitioners to have an understanding of substance misuse and the issues involved. The reader is assisted to think about how they can use their professional skills and values to inform assessments and interventions with substance users and reflective exercises encourage the reader to consider values issues and examine their own attitudes. The book will be valuable to students and practitioners wishing to update their skills and knowledge.
