Punishment under the NDPS Act by Quantity

The Narcotic Drugs and Psychotropic Substances Act, 1985 (NDPS Act) does not prescribe the same punishment for every drug offence. Since the 2001 amendment, punishment under the NDPS Act is largely graded according to the quantity of drugs involved, distinguishing small-quantity offences from offences involving commercial quantities. This distinction is important because the quantity classification under the NDPS Act affects both the applicable punishment and whether the stringent Section 37 NDPS bail conditions apply.

The Three Bands

The Act works with three categories, defined by reference to notified figures.

Small quantity — less than the quantity specified in the notification, under Section 2(xxiii-a).

Intermediate quantity — more than small but less than commercial. The Act refers to a quantity lesser than commercial and greater than small.

Commercial quantity — greater than the quantity specified in the notification, under Section 2(vii-a).

The figures themselves are not in the Act. They are set by the Central Government by notification — S.O. 1055(E) dated 19 October 2001, as amended — which lists each substance with its small and commercial quantity thresholds. Because those figures are notified and have been amended, the current notification must be consulted for the substance in question. No figures are reproduced here for that reason.

Punishment under NDPS Act by Quantity

The NDPS Act punishment provisions — including Section 20 for cannabis, Section 21 for manufactured drugs and preparations, and Section 22 for psychotropic substances — follow a graded punishment structure based on the quantity involved. Each provision is divided into three sub-clauses covering small, intermediate and commercial quantities.

Sub-clause (i) — small quantity. Rigorous imprisonment for a term which may extend to the period specified, or fine, or both. There is no mandatory minimum.

Sub-clause (ii) — intermediate quantity. Rigorous imprisonment for a term which may extend to the period specified, and fine. Again structured as a maximum rather than a minimum.

Sub-clause (iii) — commercial quantity. Rigorous imprisonment for a term not less than the minimum specified, which may extend to the maximum specified, and a fine not less than the minimum specified, which may extend to the maximum. The court may impose a fine exceeding the maximum for reasons to be recorded in the judgment.

The essential distinction is that the commercial band carries a mandatory minimum sentence, while the small and intermediate bands do not. The precise terms and fines differ between the sections and should be read from the applicable provision.

Beyond Quantity: Other Punishment Provisions

Several offences under the Act are not graded by quantity at all.

Section 27 punishes consumption of narcotic drugs or psychotropic substances, with the punishment varying according to the substance consumed.

Section 27A punishes financing illicit traffic and harbouring offenders, and carries a severe range with a mandatory minimum. It is one of the offences to which Section 37 applies irrespective of quantity.

Section 29 makes abetment and criminal conspiracy punishable with the punishment provided for the offence itself — which is why a person who never handled contraband may face the same range as one who did.

Section 31 provides enhanced punishment for repeat offences after a previous conviction, and Section 31A provides for the death penalty for certain repeat offences involving specified quantities, in the terms that section prescribes. The Supreme Court has considered the constitutionality of mandatory death sentencing in this context, and the current position on Section 31A should be verified before any reliance is placed on it.

Section 32B sets out factors a court may take into account for imposing a punishment higher than the minimum, including the use of violence or arms, the holding of public office, involvement of minors, and the quantity involved.

How NDPS Quantity Affects Sentencing and Bail

No suspension, remission or commutation in commercial cases. Section 32A restricts the ordinary powers in respect of sentences awarded under the Act, subject to the terms of that section and its judicial treatment.

Section 37 tracks the commercial band. Because the twin conditions for bail attach to commercial quantity, the same determination that fixes the sentencing range also governs pre-trial liberty.

Mixtures count. In Hira Singh v. Union of India, (2020) 20 SCC 272, decided on 22 April 2020, a three-Judge Bench held that where a drug is seized mixed with one or more neutral substances, the weight of the neutral substance is not excluded — the total mixture is taken into account in determining the band. That overruled E. Micheal Raj v. Intelligence Officer, Narcotic Control Bureau, which had held that only the actual drug content mattered.

The consequence for sentencing is direct: a modest quantity of drug in a large quantity of an inert medium can attract the commercial band, with its mandatory minimum. The distinction courts have maintained is between a mixture and a carrier — packaging and concealment material do not count towards the quantity.

A separate point on conspiracy. Because Section 29 attaches the same punishment to abetment and conspiracy, and because Section 37 applies by reference to the offence, an accused charged under Section 29 in relation to a commercial-quantity offence faces the commercial-band consequences even without recovery from his person. This is where the admissibility question decided in Tofan Singh v. State of Tamil Nadu, (2021) 4 SCC 1, on 29 October 2020, becomes central — statements recorded under Section 67 are inadmissible, and such cases frequently rest on little else.

Practical Guidance

Identify the substance and locate it in the current notification. The bands differ substantially between substances, and applying a figure from one substance to another is a serious error.

Establish which sub-clause the case falls under, since that determines whether a mandatory minimum is engaged.

Check whether the total counted includes anything that is a carrier rather than a mixture.

Where Section 29 is invoked without recovery, examine what admissible material actually supports the charge.

And read the punishment from the applicable section rather than from a general summary — the terms differ between Sections 20, 21 and 22, and between sub-clauses within each.
