Srinagar, Jun 18: An in-depth research on the drug abuse among teenagers in Srinagar has exposed a disturbing drug supply chain operating around the schools, with classmates and friends emerging as the most powerful link connecting students to narcotics. The research, conducted by Dr Sameena Wani, presently Principal, Government Girls Higher Secondary School Kothibagh, Srinagar, reveals that the drug ecosystem targeting school students no longer depends solely on street-level peddlers. The study has been submitted to the District Institute of Education and Trainings (DIET) Srinagar.
