Simplified Explanation

Section 2 of the Narcotic Drugs and Psychotropic Substances Act, 1985 (NDPS Act) provides the definitions of key terms used throughout the Act. These definitions clarify the scope and application of the law by standardizing terminology. Below is a detailed explanation of some of the most significant terms:


Key Definitions:

1. Addict (Subsection i)

  • Defined as a person dependent on any narcotic drug or psychotropic substance.
  • This term is crucial for distinguishing between casual users and individuals needing medical or rehabilitative interventions.

  • Cannabis (Hemp): Includes:
    • Charas: The resin from the cannabis plant, including hashish oil.
    • Ganja: The flowering or fruiting tops of the cannabis plant (excluding seeds and leaves unless accompanied by the tops).
    • Any mixture of the above forms.
  • Cannabis Plant: Refers to any plant of the genus Cannabis.

These distinctions help in classifying the substance for regulation and penalties.


  • Coca Derivative: Includes cocaine, ecgonine, and other derivatives used in drug manufacturing.
  • Coca Leaf: Refers to the leaf of the coca plant unless all cocaine and ecgonine alkaloids have been removed.
  • Coca Plant: Plants of the genus Erythroxylon that can produce cocaine or its derivatives.

4. Controlled Delivery and Controlled Substances (Subsections viib, viid)

  • Controlled Delivery: A law enforcement technique where illicit consignments are allowed to proceed under supervision to identify offenders.
  • Controlled Substance: Any material notified by the Central Government due to its potential use in drug manufacture.

These terms emphasize modern enforcement strategies and supply chain regulation.


5. Illicit Traffic (Subsection viiib)

  • Broadly defined to include illegal activities related to cultivation, production, possession, sale, transport, import/export, and financing or supporting these actions involving narcotic drugs or psychotropic substances.

This comprehensive definition ensures that all aspects of drug-related criminal activity are covered under the law.


6. Manufactured Drug and Medicinal Cannabis (Subsections xi–xii)

  • Manufactured Drug: Includes derivatives of coca, opium, and other notified narcotic substances, except those excluded by government notification.
  • Medicinal Cannabis: Extracts or tinctures of cannabis used for medical purposes.

These terms highlight the Act’s regulatory balance between penalizing misuse and allowing controlled medicinal use.


  • Opium: Coagulated juice of the opium poppy and mixtures containing more than 0.2% morphine.
  • Opium Derivative: Includes medicinal opium, heroin (diacetylmorphine), and preparations containing significant morphine levels.
  • Opium Poppy: The species Papaver somniferum and any other notified species that can yield opium or its alkaloids.
  • Poppy Straw: Parts of the opium poppy (except seeds) after harvesting.

These definitions are critical for the Act’s focus on controlling opium-based substances.


8. Psychotropic Substance (Subsection xxiii)

  • Refers to any natural or synthetic substance or preparation included in the specified schedule of psychotropic substances.

This term encompasses a wide range of substances affecting the mind and is central to the Act’s scope.


9. Commercial Quantity and Small Quantity (Subsections viia, xxiiia)

  • Commercial Quantity: Quantities larger than those specified by the Central Government.
  • Small Quantity: Quantities smaller than the government-specified limits.

These distinctions determine the severity of penalties under the Act.


10. Import, Export, and Transport (Subsections xxiv–xxviii)

  • Import Inter-State: Bringing substances from one state/union territory to another.
  • Import Into India: Bringing substances into India from outside, including transit in vessels or aircraft.
  • Export From India: Taking substances out of India.
  • Transport: Moving substances within the same state or union territory.

These terms regulate the movement of narcotic and psychotropic substances across borders and within India.


Explanation and Purpose of Section 2

  • Clarity and Standardization: Ensures that the Act is uniformly interpreted across judicial and enforcement bodies.
  • Flexibility: Allows the Central Government to update definitions (e.g., adding controlled substances) to address new challenges.
  • Scope and Applicability: Defines key substances and activities, forming the basis for determining offenses, penalties, and regulatory controls.
