Offences and Penalties (Sections 15–32)

Chapter IV of the Narcotic Drugs and Psychotropic Substances Act, 1985 is the punitive engine of the statute. Sections 15 to 32 convert the prohibitions of Section 8 into a graded menu of offences, each calibrated to the kind of narcotic involved and, crucially, to the quantity recovered. The architecture is deceptively simple but punishingly consequential: the same act of possession can attract six months or twenty years depending on whether the seizure crosses the threshold of "small" or "commercial" quantity. Layered over this grid are inchoate and accessorial offences — attempt, abetment, conspiracy, preparation, financing and harbouring — and an enhanced-punishment regime for repeat offenders that once carried a mandatory death sentence. This chapter maps the entire chain, section by section, against the controlling case law.

The Scheme of Chapter IV: How the Offences Are Organised

Chapter IV (Sections 15 to 40) houses every substantive penal provision of the Act. Sections 15 to 25A define what conduct is punishable and prescribe the punishment for each substance-specific contravention; Sections 26 to 30 deal with licensee offences, consumption, financing, attempt, abetment and preparation; and Sections 31 to 32B govern enhanced punishment, repeat offences and the sentencing factors a court must weigh. The drafting follows a repeated template: each section opens with "Whoever, in contravention of any provision of this Act or any rule or order made or condition of licence granted thereunder", then lists the prohibited activities (cultivation, production, manufacture, possession, sale, purchase, transport, warehousing, use, consumption, import inter-State, export inter-State or otherwise dealing), and finally lays down a three-tier punishment keyed to quantity.

The structuring principle is that the Act criminalises a single integrated chain of conduct rather than isolated acts. In Union of India v. Sanjeev V. Deshpande (2014) the Supreme Court clarified that contravention of Section 8(c) is punishable under the corresponding penal section irrespective of whether the substance appears in the Schedule to the NDPS Rules, because the Act and the Rules play complementary but distinct roles. The penal sections, in other words, draw their content from the prohibitions in Chapter II read with the definitions in Section 2. Understanding any single offence therefore requires reading three things together: the prohibited act, the substance category, and the quantity slab. For the foundational object and constitutional setting of the statute, see the introduction chapter and the broader NDPS notes hub.

The Three-Tier Quantity Structure: Small, Intermediate and Commercial

The single most important concept across Sections 15 to 23 is the quantity-linked sentencing slab introduced by the 2001 amendment. Each offence is punished on three rungs. Where the contravention involves a small quantity, the punishment is rigorous imprisonment up to six months, or fine up to ten thousand rupees, or both. Where it is more than small but less than commercial — the so-called intermediate quantity — the punishment is rigorous imprisonment up to ten years and fine up to one lakh rupees. Where it is a commercial quantity, the punishment leaps to rigorous imprisonment of not less than ten years (extendable to twenty) and fine of not less than one lakh rupees (extendable to two lakh, with power to impose more for recorded reasons).

"Small quantity" and "commercial quantity" are defined in Section 2(xxiiia) and Section 2(viia) respectively, and the actual figures for each drug are fixed by Central Government notification. The thresholds vary dramatically by substance — for heroin, 5 grams is small and 250 grams is commercial; for ganja, 1 kilogram is small and 20 kilograms is commercial. The doctrinal and tabular treatment of these slabs is dealt with in the dedicated chapter on small, intermediate and commercial quantity. What matters for the offence sections is that this slab is the master switch: it governs not only the length of the sentence but, downstream, the rigour of the bail bar under Section 37, which bites only for commercial-quantity (and a few enumerated) offences.

Weighing the Mixture: E. Michael Raj and Hira Singh

A bitterly contested question was whether, when a narcotic is recovered mixed with a neutral substance, the quantity slab is judged by the pure drug content or by the gross weight of the mixture. The earlier view came in E. Micheal Raj v. Intelligence Officer, Narcotic Control Bureau, (2008) 5 SCC 161. The appellant was found with 4.07 kg of a substance containing only about 60 grams of actual heroin (purity 1.4 to 1.6 per cent). A two-judge Bench held that for the purpose of imposing punishment under Section 21, it is the content of the offending narcotic drug — not the weight of the neutral filler — that determines whether the quantity is small, intermediate or commercial. On that reasoning, 60 grams of heroin fell well below the 250-gram commercial threshold.

That position was decisively overruled in Hira Singh v. Union of India, (2020) 20 SCC 272, where a three-judge Bench upheld the validity of Note 4 inserted by the Central Government notification of 18 November 2009. The Court held that while determining whether a seizure is of small or commercial quantity in relation to a mixture of a narcotic drug or psychotropic substance with one or more neutral substances, the entire quantity of the mixture must be taken into account and not merely the actual offending content. The practical effect is severe: a courier carrying a kilogram of powder that is 5 per cent heroin is now treated as carrying a commercial quantity. E. Michael Raj stands expressly overruled on this point. Aspirants should note that a writ petition seeking reconsideration of Hira Singh was entertained in 2025, but as the law stands the gross-weight rule governs.

Plant-Based Offences: Sections 15 to 20

Sections 15 to 20 punish contraventions relating to the raw, plant-derived narcotics. Section 15 punishes contravention in relation to poppy straw — producing, possessing, transporting, selling, purchasing, using, or dealing — on the standard three-tier quantity scale. Section 16 punishes contraventions relating to the coca plant and coca leaves, including cultivation of the coca plant. Section 17 covers prepared opium. Section 18 covers the opium poppy and opium; significantly, sub-section (a) makes the unlicensed cultivation of the opium poppy punishable with rigorous imprisonment up to ten years and fine up to one lakh rupees, regardless of quantity, while sub-section (b) applies the standard slab to production, possession and dealing in opium.

Section 19 is a special provision aimed at licensed cultivators: any cultivator licensed to grow opium poppy on government account who embezzles or otherwise illegally disposes of the opium produced or in his possession is punished with rigorous imprisonment of not less than ten years (up to twenty) and fine of one to two lakh rupees — a commercial-quantity-level punishment irrespective of how much opium is misappropriated, reflecting the breach of a fiduciary cultivation licence. Section 20 deals with the cannabis plant and cannabis: clause (a) punishes cultivation of any cannabis plant with rigorous imprisonment up to ten years and fine up to one lakh rupees; clause (b) punishes production, manufacture, possession, sale, transport and other dealings in cannabis on the three-tier quantity scale. It was on Section 20 that the Court in Madan Lal v. State of Himachal Pradesh built its conscious-possession jurisprudence, discussed below.

Manufactured Drugs and Psychotropic Substances: Sections 21 and 22

Section 21 is the workhorse of NDPS prosecutions, punishing contravention in relation to manufactured drugs and preparations — the category that captures heroin, which is a manufactured drug under Section 2(xi). It applies the three-tier slab: rigorous imprisonment up to six months (small), up to ten years (intermediate), and ten to twenty years (commercial), with fines escalating correspondingly. Section 22 mirrors this structure for psychotropic substances — those listed in the Schedule to the Act, such as amphetamines, methaqualone and a range of pharmaceutical sedatives.

The interplay between Section 22 and the Drugs and Cosmetics Act, 1940 has produced important litigation, because many psychotropic substances are also licit medicines. In Directorate of Revenue Intelligence v. Raj Kumar Arora (2025) the Supreme Court reaffirmed the principle laid down in Sanjeev V. Deshpande that the mere fact that a psychotropic substance is regulated under the Drugs and Cosmetics regime does not remove it from the purview of the NDPS Act; a substance figuring in the NDPS Schedule remains punishable under Section 22 even if it is not separately listed in the Schedule to the NDPS Rules. The two statutes operate in parallel, and a manufacturer or trader dealing in a Schedule psychotropic substance in contravention of the NDPS Act cannot escape by pointing to a drug licence under the 1940 Act.

Cross-Border Offences: Sections 23 and 24

Section 23 punishes the illegal import into India, export from India or transhipment of narcotic drugs and psychotropic substances. It too follows the three-tier quantity scale — small (up to six months), intermediate (up to ten years), and commercial (ten to twenty years) — and is the provision most often invoked against international couriers and consignments intercepted at ports and airports. The offence is complete on the act of import, export or transhipment in contravention of Section 8 read with the import/export provisions of Chapter III.

Section 24 is harsher and is unusual in being quantity-blind. It punishes external dealings in narcotic drugs and psychotropic substances — that is, engaging in or controlling any trade by which such drugs are obtained outside India and supplied to a person outside India — without the previous authorisation of the Central Government. The punishment is rigorous imprisonment of not less than ten years (up to twenty) and fine of one to two lakh rupees, regardless of the quantity involved. The provision targets Indian-based controllers of trans-national trafficking networks who never physically touch the contraband within India, treating their orchestration of cross-border supply as inherently grave.

Premises, Controlled Substances and Licensees: Sections 25, 25A and 26

Section 25 fixes vicarious-style liability on the owner or occupier of premises (or the person in charge of a conveyance or animal) who knowingly permits it to be used for the commission of an offence under the Act. Such a person is liable to the same punishment as is provided for that offence. Knowledge is the gravamen — a landlord or vehicle owner is not caught unless he knowingly allows the premises or conveyance to be used for trafficking, which keeps the section consistent with the Act's overall insistence on a culpable mental state.

Section 25A punishes contravention of any order made under Section 9A relating to controlled substances — precursors and chemicals used to manufacture narcotics. The punishment is rigorous imprisonment up to ten years and fine of one to two lakh rupees (with power to impose more for recorded reasons). This provision arms the State against the upstream chemistry of drug production. Section 26 deals with offences by licensees: a person to whom a licence, permit or authorisation has been granted who contravenes its conditions, omits required entries in records, or makes false entries, is punishable with imprisonment up to three years, or fine, or both — a comparatively lighter regulatory offence reflecting the diversion-from-licit-channels concern rather than outright trafficking.

Consumption: Section 27 and the Addict-Not-Trafficker Distinction

Section 27 carves out a deliberately lenient regime for consumption of narcotic drugs or psychotropic substances, recognising the Act's secondary object of treating addicts as victims rather than as hardened criminals. Where the drug consumed is cocaine, morphine, diacetylmorphine (heroin) or any other drug specified by Central Government notification, the punishment is rigorous imprisonment up to one year, or fine up to twenty thousand rupees, or both. For consumption of any other narcotic drug or psychotropic substance, the punishment is imprisonment up to six months, or fine up to ten thousand rupees, or both.

The leniency is reinforced structurally by Section 64A, which offers immunity from prosecution to an addict charged with a consumption offence (or with possession of a small quantity for personal consumption) who voluntarily seeks de-addiction treatment. Section 27 thus operates as the doctrinal hinge between the criminal-justice and public-health strands of the statute. In practice it surfaces in bail and trial strategy: an accused found with a small quantity will often argue that the recovery is consistent with personal consumption rather than trafficking, seeking the gentler treatment the Act extends to users — though the burden of bringing the case within Section 27 lies on the accused.

Financing Illicit Traffic and Harbouring: Section 27A

Section 27A, inserted to attack the money and shelter behind trafficking, punishes whoever indulges in or finances, directly or indirectly, any of the activities specified in Section 2(viiib) (the definition of "illicit traffic"), or who harbours any person engaged in such activities. The punishment is rigorous imprisonment of not less than ten years (extendable to twenty) and fine of one to two lakh rupees, with power to exceed two lakh for recorded reasons. Like Section 24, it is quantity-blind and pitched at the commercial-quantity sentencing level.

The provision is aimed at financiers and shelter-givers who form the backbone of organised trafficking but stay at arm's length from the contraband itself. Courts have, however, cautioned against its overbroad use. The mere act of arranging or paying for drugs for a friend's personal use does not, without more, amount to "financing illicit traffic"; the prosecution must establish a real financial nexus to a trafficking activity within Section 2(viiib). Section 27A is also one of the offences for which the stringent twin-conditions bail bar under Section 37 applies, making it among the most consequential charges in the Act despite its brevity. A drafting anomaly that briefly omitted Section 2(viiib) from cross-reference was corrected by retrospective ordinance, restoring the provision's intended reach.

Inchoate and Accessorial Offences: Sections 28, 29 and 30

Three provisions extend liability beyond the completed offence. Section 28 punishes attempts to commit any offence under Chapter IV with the same punishment as is provided for the offence itself — a marked departure from the general law of attempt under the penal code, which usually punishes attempt with a lesser term. Section 29 deals with abetment and criminal conspiracy: whoever abets, or is party to a criminal conspiracy to commit, an offence under Chapter IV is punishable with the punishment provided for that offence, whether or not the offence is in fact committed in consequence of the abetment or conspiracy, and notwithstanding anything in the general criminal law. The combined effect of Sections 28 and 29 is that the architects, abettors and conspirators of a trafficking operation face the same sentencing exposure as the person who physically carries the drugs.

Section 30 punishes preparation — a stage ordinarily not criminalised in general criminal law. Whoever makes preparation to do or omit anything that would constitute an offence under Sections 19, 24 or 27A, or any offence involving a commercial quantity, is punishable, if the preparation is by reason of circumstances proved to be one which the person was determined to carry out, with rigorous imprisonment of not less than half the minimum term and fine of not less than half the minimum fine for the substantive offence, extendable up to half the maximum. Section 30 thus criminalises the determined planning of the gravest NDPS offences, pushing the line of liability back from attempt to preparation.

Conscious Possession: The Mental Element in Possession Offences

Although the offence sections speak simply of "possession", the courts have grafted on a settled requirement of conscious possession. In Madan Lal v. State of Himachal Pradesh (2003) the Supreme Court held that mere physical custody is not enough; Section 20 (and by parity the cognate sections) is attracted only where possession is coupled with the requisite mental element — awareness of the nature of what is possessed. Whether possession is conscious is a question of fact to be determined on the circumstances of each case.

This was elaborated in Mohan Lal v. State of Rajasthan (2015), where the Court explained that "possession" is a polymorphous term embracing physical possession with animus, custody with animus, dominion and control through concealment, or personal knowledge of the existence of the contraband. Crucially, the Court read this together with Section 35 and Section 54, which raise a statutory presumption of a culpable mental state and of commission of the offence once possession of the contraband is established. The practical consequence is a reverse burden: once the prosecution proves recovery and possession, the onus shifts to the accused to establish that the possession was not conscious, that fact being within his special knowledge. The conscious-possession doctrine therefore tempers the strict-liability appearance of the offence sections while the statutory presumptions keep the evidentiary balance tilted toward the prosecution.

Enhanced Punishment and the Death Penalty: Sections 31 and 31A

Section 31 provides enhanced punishment for repeat offenders. A person previously convicted of an offence under Chapter IV who is again convicted is liable to a term up to one-and-a-half times the maximum term, and a correspondingly enhanced fine, prescribed for the subsequent offence. The mechanics and qualifying conditions of this provision are treated in detail in the chapter on punishment for repeat offences.

Section 31A originally prescribed a mandatory death sentence for a repeat conviction involving specified large quantities of certain drugs (such as opium, morphine, heroin, hashish and cocaine above stated thresholds). In Indian Harm Reduction Network v. Union of India (Bombay High Court, 16 June 2011) a Division Bench held that the mandatory character of the death penalty under Section 31A violated Articles 14 and 21, since a law that strips the court of all sentencing discretion in a matter of life and death is harsh, unjust and unfair. Rather than striking the provision down entirely, the Court read down the word "shall" so that the death penalty became discretionary, leaving the court free to impose life imprisonment instead, consistent with the rarest-of-rare doctrine of Bachan Singh. Parliament subsequently endorsed this position through the 2014 amendment, which made death an alternative to a thirty-year term. Section 31A thus survives, but the death sentence under it is now a matter of judicial discretion, not statutory compulsion.

Sentencing Discretion: Sections 32, 32A and 32B

The closing provisions of the punishment scheme structure how courts impose and administer sentences. Section 32 provides that no offence under the Act is punishable with imprisonment for less than the minimum term or fine prescribed, with a narrow saving where a lesser punishment is expressly permitted by the section creating the offence — reinforcing the mandatory-minimum philosophy that animates the statute. Section 32A bars suspension, remission and commutation of sentences awarded under the Act except as provided in the Act, and forbids the ordering of sentences to run concurrently — though parts of its rigour have been read down by later jurisprudence concerning the executive power to remit.

Section 32B lists the factors a court may take into account, beyond those specified in the Act, while imposing a sentence higher than the minimum — including the use of violence or arms, the offender's holding of public office, involvement of minors, and the quantity involved. In Rafiq Qureshi v. Narcotic Control Bureau, Eastern Zonal Unit (2019) the Supreme Court held that the absence of the specific factors enumerated in clauses (a) to (f) of Section 32B does not preclude a court from imposing a sentence above the statutory minimum; the language "may, in addition to such factors as it may deem fit" is permissive and enabling, so a court may rely on other relevant considerations, such as the sheer quantity of contraband, to justify a higher sentence. Section 32B therefore widens rather than confines judicial discretion in calibrating punishment within the statutory range.
