The statutory frame for sale, storage and prescription of poisons and scheduled drugs in India: Poison Act 1919, the Drugs and Cosmetics Act 1940 and the 1945 Rules, and the schedules H, H1, X and G that decide what reaches the public counter.
The statutory frame for poisons in India is older than the country itself. The Poison Act 1919 is a colonial-era 17-section statute that still governs the sale and possession of substances notified by state governments. The Drugs and Cosmetics Act 1940, with its 1945 Rules, sits on top of it and runs the schedules (G, H, H1, X, F, J) that decide what the chemist on the corner can hand over without a prescription and what they cannot. The NDPS Act 1985 covers the narcotic and psychotropic layer above that. The Insecticides Act 1968 covers pesticides, which dominate Indian rural poisoning. A working forensic toxicologist or pharmacist has to hold all four statutes in their head at once, because a single bottle of strychnine, a sedative blister or a bag of monocrotophos can sit under two or three of them simultaneously.
The thing most candidates and most pharmacy inspectors miss is that the schedules are not an internal lab classification, they are a public-facing labelling and dispensing rule. A red-bordered "Schedule H Drug" panel on the carton is not decorative, it is statutory text under Rule 96 of the Drugs and Cosmetics Rules 1945. A pharmacist who hands a Schedule H1 antibiotic across the counter without entering it in the H1 register has committed an offence, and the State Drug Controller can suspend the shop's licence on the next inspection. This topic walks through each statute in turn, the schedules under the 1945 Rules, the criminal-law sections that intersect (BNS 125, BNS 274, BSA 63), and the procedural safeguards under NDPS that decide whether a recovery survives the trial court.
Seventeen sections, no schedule of its own, all the schedule-making power delegated to the states.
The Poison Act 1919 was enacted by the Imperial Legislative Council and continues in force under Article 372 of the Constitution. It has only seventeen sections and no schedule of its own. The substantive scheme is short. Section 2 empowers the state government to regulate the possession for sale, and the sale, of any substance specified by notification. Section 3 empowers the state government to regulate import. Section 4 lets the state make rules on licensing, labelling, conditions of sale, the maintenance of registers, and the inspection of premises. Section 6 makes contravention an offence punishable with imprisonment up to three months, or a fine up to five hundred rupees, or both, and a heavier punishment of six months on a second conviction.
Because the Act delegates the schedule entirely to the states, what counts as a "poison" varies by state. The substances most commonly notified in the State Poisons Rules across India are mercury and its compounds, arsenic and its compounds, hydrocyanic acid and cyanide salts, organophosphate concentrates (parathion, monocrotophos), strychnine, oxalic acid, phosphorus, and a long list of mineral acids and alkalis at concentration cut-offs. Each notified state list mirrors the others closely but is not identical. The Delhi Poison Rules, the Maharashtra Poison Rules and the Tamil Nadu Poison Rules differ in the specific concentration thresholds for certain industrial chemicals.
The license categories under the typical state Poison Rules are three: a Form 1 licence for general retail sale, a Form 2 licence for wholesale, and a Form 3 licence for use in a trade or profession (electroplating, photography, leather, pest control). A licensee must keep a Form 4 register of sales recording the name and address of the purchaser, the substance and quantity sold, the purpose stated, and the signature of the purchaser. The register is open to inspection by any officer authorised by the state government, which in practice means the Drug Inspector or the local police.
The central statute, the rules that do the real work, and the schedules at the back.
The Drugs and Cosmetics Act 1940 is the central statute. The Drugs and Cosmetics Rules 1945, framed under Section 33 of the Act, do the operational work. The Act is divided into chapters covering import (Chapter III), manufacture, sale and distribution (Chapter IV), Ayurvedic, Siddha and Unani drugs (Chapter IVA), and offences (Chapter V). The schedules to the Rules, lettered A through Y, are where a forensic toxicologist and a pharmacist actually look.
| Schedule | What it lists | Counter rule | Warning panel / storage |
|---|---|---|---|
| Schedule G | Substances requiring caution (antihistamines, hypoglycaemics, antiepileptics, anti-cancer drugs) | Sold without a prescription but with the statutory caution | 'Schedule G drug. Caution: it is dangerous to take this preparation except under medical supervision.' |
| Schedule H | Prescription drugs: most antibiotics, sedatives, antipsychotics, antihypertensives, hormones | Sold only on a registered medical practitioner's prescription; entry in the prescription register | Red rectangular box with the legend 'Schedule H Drug. Warning: To be sold by retail on the prescription of a Registered Medical Practitioner only.' |
| Schedule H1 | Forty-six substances notified in 2014: third and fourth generation antibiotics, anti-TB drugs, habit-forming preparations |
The statute that supplies most of the cases at every state FSL narcotics section.
The NDPS Act 1985 replaced the older Opium Act 1857, the Opium Act 1878 and the Dangerous Drugs Act 1930. It is the principal narcotics statute in India and supplies a very large share of the casework at every state FSL narcotics section. Five provisions matter for a forensic toxicology student.
Where most of the rural poisoning casework actually sits.
The Insecticides Act 1968 regulates the import, manufacture, sale, transport, distribution and use of insecticides to prevent risk to human beings and animals. The statute is administered by the Central Insecticides Board and Registration Committee, with state-level Insecticide Inspectors. Three schedules attached to the Rules 1971 carry the operative lists: a registered-insecticides schedule, a packaging and labelling schedule (with the colour-coded toxicity triangle: red for extremely toxic, yellow for highly toxic, blue for moderately toxic, green for slightly toxic), and an antidote schedule.
The Anupam Verma Committee, constituted by the Ministry of Agriculture in 2013 to review 66 insecticides flagged as banned or restricted in other jurisdictions but still registered in India, submitted its report in 2015 and a follow-up in 2018. The Ministry acted in stages: a 2018 order banned 18 insecticides outright (including alachlor, dichlorvos for household use, methyl parathion concentrate above 50 percent, phorate, triazophos for certain crops). A draft 2020 order proposed banning a further 27 substances (chlorpyrifos, monocrotophos, mancozeb, oxyfluorfen among them) but the final notification has been repeatedly stayed and remains contested.
The forensic relevance is direct. Monocrotophos and chlorpyrifos remain the two organophosphates most frequently identified in Indian post-mortem viscera (covered in the pesticide poisoning topic). Aluminium phosphide, sold as Celphos or Quickphos for grain fumigation under the Insecticides Act, is the leading suicide-by-poisoning agent in Punjab and Haryana. Endosulfan was banned in 2011 by Supreme Court order after the Kasaragod (Kerala) cluster; the ban survived a series of industry challenges.
How a poison case actually moves from the chemist's counter to the trial court.
The poison and drug statutes regulate the supply side. The criminal law overlay punishes the misuse. The Bharatiya Nyaya Sanhita 2023 replaced the Indian Penal Code 1860 with effect from 1 July 2024, and the relevant sections renumber. The Bharatiya Sakshya Adhiniyam 2023 (BSA) replaced the Indian Evidence Act 1872 and decides what the chemical examiner's report looks like in court.
| Conduct | IPC 1860 (old) | BNS 2023 (new) | Statutory frame for the substance |
|---|---|---|---|
| Adulteration of drugs | Section 274 IPC | Section 274 BNS (retained number) | Drugs and Cosmetics Act 1940, Section 17 |
| Sale of adulterated drugs | Section 275 IPC | Section 275 BNS | Drugs and Cosmetics Act 1940, Sections 17 and 18 |
| Sale of drug as different drug | Section 276 IPC | Section 276 BNS | Drugs and Cosmetics Act 1940, Section 18 |
| Causing hurt by poison | Section 328 IPC | Section 125 BNS | Poison Act 1919 / Drugs and Cosmetics Act / NDPS Act, depending on the substance |
From licence on the wall to the register at the back.
Take a chemist shop in Karol Bagh, Delhi, or Dadar, Mumbai. The licence on the wall is Form 20 (for retail sale of drugs other than Schedule X) and Form 21 (for retail sale of restricted drugs including Schedule X), both issued under the Drugs and Cosmetics Rules 1945 by the State Drugs Controller. A registered pharmacist registered with the State Pharmacy Council must be on the premises during business hours; the registration number is displayed beside the licence.
At the counter, the dispensing flow runs in tiers. A Schedule G item (a hypoglycaemic, an antihistamine) is sold over the counter with the caution legend on the carton; no register entry is required, although best practice is to note the sale in the daily sales register. A Schedule H item (most antibiotics, sedatives, antipsychotics) is sold only against a registered medical practitioner's prescription, and the prescription is entered in the prescription register with the prescriber's name, registration number and address. A Schedule H1 item (a third-generation antibiotic, an anti-TB drug, alprazolam) goes one step further: the dispensing is logged in the separate H1 register, the register is retained for three years, and a photocopy of the prescription is taken if the chemist is following industry best practice.
A Schedule X item is the strictest tier under the 1940 Act. The cupboard is under double lock with the key held by the registered pharmacist. The prescription is written in duplicate on the prescriber's letterhead; the pharmacist keeps one copy for two years. A Form 41 register records each Schedule X transaction. The Drug Inspector inspects the cupboard, the register and the duplicate prescriptions on routine visits. A narcotic preparation (codeine syrup above the schedule threshold, morphine, methadone) sits one tier above Schedule X under the NDPS Act; only a chemist holding the additional state narcotics licence can dispense it, and the dispensing register is open to NCB and state excise inspection.
Which statute governs the sale of mercury, arsenic and hydrocyanic acid as 'poisons' to a member of the public in India?
| Separate H1 register maintained for three years; copy of prescription retained |
| Red border 'Rx' symbol plus the Schedule H1 warning. |
| Schedule X | Psychotropic substances and certain narcotics (amphetamines, methylphenidate, secobarbital, glutethimide) | Prescription in duplicate, one copy retained by the pharmacist; double-lock storage; register kept for two years | 'Schedule X drug' label; storage under double lock with restricted access. |
| Schedule F | Standards and storage conditions for biological products (sera, vaccines, blood products) | Storage and cold-chain rules under the schedule | Cold-chain labelling per the schedule. |
| Schedule J | Fifty-six diseases that no drug may claim to cure (AIDS, cancer, diabetes, hypertension, leprosy, infertility, etc.) | Advertising and labelling prohibition | No claim permitted in the labelling, package insert or advertising. |
| Schedule M | Good Manufacturing Practices for drug manufacturers | Manufacturing licence conditioned on Schedule M compliance | Facility audited by CDSCO and state drug controllers. |
The schedules most often asked about, and the schedules that most often turn up in defence cross-examination of a forensic toxicologist, are H, H1 and X. The 2014 amendment that introduced Schedule H1 was driven by the Indian antimicrobial resistance crisis. The 46 listed substances include third and fourth generation cephalosporins (cefepime, cefpirome), the carbapenems (meropenem, ertapenem), the newer fluoroquinolones (moxifloxacin), most anti-TB drugs (rifampicin, isoniazid, ethambutol, pyrazinamide), and the habit-forming sedatives (alprazolam, diazepam in injectable form, tramadol). A retail chemist must maintain a separate Schedule H1 register recording the prescriber's name and registration number, the patient's name and age, the drug and quantity dispensed, and the date. The register is retained for three years.
Schedule X is the closest the 1940 Act gets to NDPS-style control. The listed substances are psychotropic stimulants and sedatives that were considered abuse-prone enough to need double-lock storage but were not transferred wholesale to NDPS. The retail dispensing rules are stricter than Schedule H: the prescription must be written in duplicate on the prescriber's letterhead, the pharmacist retains one copy for two years, the drug is dispensed only against the original, and the storage cupboard is under double lock with the key held by the registered pharmacist. The Form 41 register for Schedule X is open to inspection by the Drug Inspector and by CDSCO officers.
Two Supreme Court judgments are essential. State of Punjab v Baldev Singh (1999) is the Constitution Bench that read Section 50 as a mandatory procedural safeguard. The empowered officer must inform the suspect of the right to be searched before a gazetted officer or a magistrate; failure to do so vitiates the search and makes the recovery inadmissible. The principle has been refined in subsequent benches (Vijaysinh Chandubha Jadeja v State of Gujarat (2011), among others) but the core position has held.
Tofan Singh v State of Tamil Nadu (2020) is the more recent and arguably more consequential ruling. A three-judge bench held that the confessional statement of an accused recorded by an officer empowered under Section 53 of NDPS (typically an NCB or DRI officer) is not admissible against the maker. The Court held that such officers are "police officers" for the purposes of the bar in Section 25 of the Indian Evidence Act 1872 (now Section 23 of the Bharatiya Sakshya Adhiniyam 2023). Before Tofan Singh, prosecutions routinely relied on a Section 67 statement recorded by the empowered officer; after Tofan Singh, that route is closed.
| Culpable homicide by poison | Section 299 / 300 IPC | Sections 99 to 101 BNS | Same; the substance trail goes through the schedule that covers it |
| Chemical examiner's report | Section 293 CrPC; Section 510 CrPC; IEA Section 45 / 65B | Section 329 BNSS; BSA Section 39 and Section 63 | The FSL toxicology report becomes a document of the court under BNSS 329; expert deposition under BSA 39; electronic exhibits under BSA 63 |
The most often-cited section in homicidal poisoning prosecutions used to be Section 328 IPC ("causing hurt by means of poison etc with intent to commit an offence"). The renumbered provision is Section 125 of the BNS. The elements are the same: the accused administered to or caused to be taken by another person any poison, stupefying, intoxicating or unwholesome drug, with intent to cause hurt, or to facilitate the commission of an offence, knowing the act likely to cause hurt. The chemical examiner's report identifying the poison in the viscera or in the food residue is the linchpin of such a prosecution. After the 2023 transition, the report comes into court under BNSS Section 329 (the renumbered Section 293 CrPC) and is read along with the expert's deposition under BSA Section 39.
Under BSA Section 63, any electronic copy associated with the case (a CCTV clip from the chemist shop showing the sale, a WhatsApp screenshot of the order, an Excel sheet of the H1 register) is admissible only with the Section 63 certificate. The post-Anvar / post-Khotkar jurisprudence on the certificate, set out in our BSA topic, applies in poison cases just as it does in any other.
The 2023 New Drugs and Clinical Trials Rules, notified by the Ministry of Health and Family Welfare in 2019 and refined since, separated out the new drug approval process and the clinical trial regulation from the body of the 1945 Rules. Clinical trials are now governed by these standalone rules, with an expanded role for the Subject Expert Committees and the Central Drugs Standard Control Organization. The change matters for syllabus updates because earlier course material referred only to Schedule Y of the 1945 Rules; the 2023 rules supplement Schedule Y for clinical trial protocols, informed consent, and adverse-event reporting.
The Indian Pharmacopoeia Commission at Ghaziabad publishes the Indian Pharmacopoeia, the official compendium of drug standards. Each substance entry specifies identity tests, assay methods, impurity limits and storage conditions. A drug failing IP standards is "not of standard quality" under the 1940 Act and may attract action under Sections 17, 17A and 18. CDSCO in Delhi, headed by the Drugs Controller General of India, is the federal regulator; state drug controllers run the field operations.
