NARCOTIC DRUGS AND PSYCHOTROPIC SUBSTANCES ACT, 1985: A TEACHER’S COMPREHENSIVE GUIDE TO NDPS ACT, OFFENCES, AND PENALTIES
Welcome, future pharmacists and healthcare professionals!
As a pharmacy law and ethics educator with years of experience teaching pharmaceutical legislation, I have observed that the Narcotic Drugs and Psychotropic Substances Act, 1985 (NDPS Act), is one of the most stringent and comprehensive pieces of legislation in India. The Central Acts like Opium Act, 1857, the Opium Act, 1878 and the Dangerous Drugs Act, 1930 were enacted a long time ago. With the changing circumstances and developments in illicit drug traffic and drug abuse at national and international level, many drawbacks came to notice. The Government of India repealed these old Acts and passed “The Narcotic Drugs and Psychotropic Substances Act, 1985” on 14 November 1985, covering all regions of India.
In this comprehensive guide, I will take you through the applicability, objectives, definitions, authorities and officers, prohibited operations, powers to permit, control and regulate, and offences and penalties under the NDPS Act. By the end of this article, you will have a thorough understanding of the legal framework governing narcotic drugs and psychotropic substances in India. Let us begin.
