This book investigates the complex decision-making processes that influence drug-taking behaviors as individuals transition from adolescence into adulthood. Lisa Williams, drawing on extensive qualitative research and longitudinal interviews, examines how social environments, personal circumstances, and life events shape the trajectory of substance use over time. The work argues that drug use is not a static behavior but a dynamic process influenced by shifting identities and structural constraints throughout the life course.

Experts in the field of criminology and sociology recognize this work as a significant contribution to understanding the developmental aspects of substance use. Readers frequently note the academic rigor of the text, making it a valuable resource for researchers and practitioners interested in behavioral change.
