Described by the National Crime Agency as a ‘significant threat’, county lines involve gangs recruiting vulnerable youth to sell drugs in provincial areas. This phenomenon has impacted local drug markets, increasing criminal activity and violence. Exploring how county lines evolve, Harding reveals extensive criminal exploitation and control in the daily ‘grind’ to sell drugs. Drawing upon extensive interviews and case studies, this timely book gives voice to users and dealers, providing an in-depth analysis of techniques, relationships and ‘trapping’. With county lines now a critical issue for policing and government, this is an invaluable contribution to literature on gangs, youth violence and drugs.
