How is UK drugs policy made, and why does it so often seem irrational when considering what works in reducing drug-related harms?

This book explains how the concept of drug policy constellations – the loosely concerted policy actors with shared moral commitments that influenced policy outcomes – explains why there is no such thing as 'evidence-based' drug policy. Drawing on his participation in high-level policy discussions, and a novel approach to policy analysis, Stevens presents three recent cases involving key issues in UK illicit drug policy – medical cannabis, drug-related deaths and the government's 10-year drug strategy.
