The Narcotic Drugs and Psychotropic Substances Act (NDPS Act) is a comprehensive statute designed to prevent and control illicit production, trafficking, sale, and consumption of narcotic drugs and psychotropic substances. It criminalizes unauthorised cultivation, manufacture, possession, transportation and distribution of controlled substances while balancing supply reduction measures with limited provisions for treatment and rehabilitation of addicts. The Act aims to protect public health and social order by imposing strict penalties and establishing procedures for investigation, search, seizure and trial.
NDPS cases involve complex forensic, investigative and procedural issues. Defendants and legal counsel must pay careful attention to chain-of-custody for seized substances, legality of searches and seizures, compliance with statutory procedures, classification of seized material, and calculation of statutory thresholds. Given strict punishments and procedural presumptions, legal strategy typically focuses on procedural compliance by investigating agencies, scientific identification of substances, challenging possession and knowledge presumptions, and highlighting mitigating circumstances such as addiction or absence of mens rea.
