West Bengal (পশ্চিমবঙ্গ, Pashchimbanga) is a state in eastern India, bordering Bangladesh to the east, Nepal and Bhutan to the north and the Indian states of Sikkim, Assam, Bihar, Jharkhand and Odisha. The state extends from the Himalayan foothills in the north to the Bay of Bengal in the south, encompassing three of the wiki's documented growing regions: the Eastern Himalayas, The Dooars and the North Bengal Plains. It is the most extensively surveyed Indian state on the wiki, with all current Indian accessions originating from the 2025 WEB01 expedition across its northern districts.citation needed

Geography

West Bengal covers 88,752 km² between 21°25′ N and 27°13′ N. North-south extent is approximately 600 km. The conventional physiographic division of the state separates the Himalayan north, the Terai-Dooars piedmont and the Gangetic deltaic plain.[1] Bandyopadhyay et al. (2015) subdivide the state into nine geomorphological zones: the Darjeeling Himalaya, sub-Himalayan alluvial fans, the Barind uplands, the degenerated Chhotanagpur plateau fringe, the lateritic Rarh, the upper Ganga delta, the reclaimed lower delta, the non-reclaimed mangrove Sundarbans and the Medinipur coastal plain.[1] Elevations range from sea level in the Sundarbans to 3,636 m at Sandakphu on the Singalila Ridge.[2]

Physiography

The Darjeeling Himalaya occupies about one per cent of the state's area but contains its highest relief. Phyllites and schists predominate around Kalimpong. Gneiss dominates around Darjeeling. The rocks have been intensely sheared by the underthrusting of the Indian plate, producing slope instability and landslide hazard across the hill districts.[2] The Singalila Ridge on the India-Nepal boundary carries Sandakphu (3,636 m), the highest point in West Bengal, and Phalut (3,600 m). The Teesta gorge separates the Singalila and Darjeeling ranges to the west from the lower hills around Kalimpong to the east.

South of the Himalayan front a belt of Bhabar (gravel and boulder fans) and Terai (clay and sand alluvium with a high water table) grades into the Dooars piedmont. The Dooars proper lies between 90 m and 1,750 m elevation across Jalpaiguri, Alipurduar and the northern margin of Cooch Behar.[3]

The Rarh region of the southwest (Purulia, Bankura, Birbhum, parts of Paschim Bardhaman and Paschim Medinipur) is an undulating laterite-capped erosional surface continuous with the Chota Nagpur plateau. The Bhagirathi separates Rarh to the west from Bagri to the east in Murshidabad. The Sundarbans form a tidally active distal delta of the Ganga-Brahmaputra-Meghna system, simultaneously prograding and eroding. Surface elevations range from 0.5 m to 3 m, with about seventy per cent of the area below 1 m.

Climate

Köppen-Geiger classifications follow the relief of the state. The Darjeeling and Kalimpong hills are subtropical highland (Cwb). Most of the western and northern plains are humid subtropical (Cwa). Kolkata, Haldia and the deltaic south are tropical wet-and-dry (Aw).[4] The India Meteorological Department treats the state under two meteorological subdivisions: Gangetic West Bengal and Sub-Himalayan West Bengal and Sikkim.

Four seasons are recognised: winter (December to February), pre-monsoon (March to May, with Kalbaishakhi or Nor'wester thunderstorms in the south), the southwest monsoon (June to September) and the retreating or post-monsoon (October to November). The Bay of Bengal supplies the moisture. The Himalaya force orographic uplift. Rainfall therefore increases northward and into the foothills. Seventy-five to eighty per cent of annual rainfall falls during the southwest monsoon.[4] Tropical cyclones including Aila (2009), Amphan (2020) and Yaas (2021) periodically affect the deltaic and coastal districts.

Representative climate stations
Station Köppen Mean annual temperature (°C) Mean annual rainfall (mm)
Darjeeling (2,042 m) Cwb 14.9 3,100
Jalpaiguri (Dooars) Cwa 24.5 3,200
Kolkata (Alipore) Aw 26.7 1,711.5
Malda Cwa 25.4 1,349
Asansol (Rarh) Cwa 25.3 1,294
Haldia (coast) Aw 26.2 1,654

Long-term records at Darjeeling indicate a mean annual temperature increase of about 4 °C since the late nineteenth century, with a concurrent decline in annual rainfall.[5]

Rivers and hydrology

Three drainage systems converge in West Bengal. Himalayan rivers (the Teesta, Jaldhaka, Torsa, Raidak, Sankosh and Mahananda) drain North Bengal and ultimately the Brahmaputra. The Ganga-Padma-Bhagirathi/Hooghly system dominates central and southern Bengal. At the Farakka Barrage the river splits into the Padma (which crosses into Bangladesh) and the Bhagirathi-Hooghly (which carries the southward flow to the Bay of Bengal through Kolkata and Haldia). Peninsular rivers originating in the Chota Nagpur plateau (the Damodar, Ajay, Mayurakshi, Rupnarayan and Kangsabati) drain the Rarh.

The combined catchment of the five major North Bengal rivers (Teesta, Torsa, Jaldhaka, Raidak and Sankosh) within West Bengal is 37,545 km².[6] The Sundarbans tidal network (the Hooghly, Matla, Bidyadhari, Raimangal, Ichhamati and Saptamukhi distributaries with their creeks) covers about 4,260 km² in India, of which 1,700 km² is open water.[7]

The Padma-Ganga and lower Bhagirathi floodplains, with their light well-drained silt-renewed alluvial loams, supplied the agronomic foundation of the historical Bengal ganja economy across both banks of what is now the international border. The Indian portion of this belt lies in Murshidabad, Malda, Nadia and the northern fringe of North 24 Parganas (see History below).

Soils

The state's soil cover, classified by the Indian Council of Agricultural Research's National Bureau of Soil Survey and Land Use Planning, comprises six broad families.[8]

  • Gangetic (new) alluvium. Neutral to mildly alkaline (pH 7.0–8.2), deep, fertile and high in water-holding capacity. Underlies Murshidabad, Nadia, Hooghly, the Bardhaman districts, North 24 Parganas and much of South 24 Parganas. About 3.5 million hectares of alluvial soils statewide.
  • Vindhya (old) alluvium. Derived from Rajmahal and Chotanagpur drainage; mildly acidic (pH 6.0–6.6). Parts of Murshidabad, Birbhum and Purba Bardhaman.
  • Lateritic and red soils. Coarse, well-drained, ferruginous and acidic (pH 5.5–6.9), low in organic matter. Purulia, Bankura, Birbhum, parts of Paschim Bardhaman and Paschim Medinipur. The Rarh soil regime.
  • Terai and Bhabar soils. Darjeeling foothills, Jalpaiguri, Alipurduar and Cooch Behar. Acidic (pH 6.0–6.6), nutrient-poor on the higher fans. Support tea on the better-drained slopes.[3]
  • Coastal saline and alkaline soils. South 24 Parganas (Sundarbans), parts of Howrah and Purba Medinipur. Calcium- and magnesium-rich with decomposed organic matter. Salinity from tidal inundation.
  • Mountain (skeletal and colluvial) soils. Darjeeling and Kalimpong. Thin and well-drained, supporting tea on the lower flanks and temperate-forest soils above.

Ecology and forests

West Bengal lies at the junction of three biogeographic provinces: the Eastern Himalaya (a global biodiversity hotspot), the Indo-Gangetic plain and the Deccan Peninsular (via the Chota Nagpur plateau). Four principal forest types are mapped under the Champion and Seth classification:

  1. Tropical moist and dry deciduous Sal forests of the Dooars and Terai. Shorea robusta with Tectona grandis, Bombax ceiba and Lagerstroemia. The Mahananda, Gorumara, Jaldapara, Buxa and Chapramari protected areas lie within this belt.
  2. Tropical dry deciduous and sal coppice of the plateau fringe. Medinipur, Bankura, Purulia, the Bardhaman districts and Birbhum. Dominated by sal with Butea monosperma, Madhuca longifolia and Diospyros melanoxylon. The Jhargram, Garhbeta and Ayodhya Hill ecosystems fall here.
  3. Tidal mangrove forests of the Sundarbans. Heritiera fomes (sundari), Excoecaria agallocha (gewa), Avicennia spp., Ceriops decandra (goran) and Phoenix paludosa (hantal). The Sundarban Biosphere Reserve covers 9,630 km² in India and contains the Sundarban Tiger Reserve, Sajnekhali, Lothian and Halliday Island sanctuaries.
  4. Subtropical broadleaf and temperate forests of the Darjeeling-Kalimpong hills. Quercus, Castanopsis, Michelia, Rhododendron, Magnolia and Tsuga dumosa. The Singalila and Neora Valley National Parks protect the highest reaches.

Recorded forest cover totals 16,901.51 km², or 19.04 per cent of the state's geographic area.[7] The Sundarbans hold about 2,114 km² of dense mangrove forest, the largest single block in India and (combined with the Bangladeshi portion of the same delta) the largest contiguous mangrove forest in the world.[9] Two tiger reserves operate in the state: the Sundarban Tiger Reserve (3,629.57 km², the second-largest tiger reserve in India following the August 2025 area expansion approved by the National Board for Wildlife)[10] and the Buxa Tiger Reserve in the Dooars. Three communities are notified as Particularly Vulnerable Tribal Groups (PVTGs): the Toto, the Birhor and the Lodha.

Administrative geography

West Bengal is administered through five divisions (Presidency, Burdwan, Medinipur, Malda and Jalpaiguri) comprising twenty-three districts as of 1 November 2023. Each division corresponds approximately to a coherent physiographic region: Presidency to the lower deltaic plain; Burdwan to the Rarh and Damodar valley; Medinipur to the southwestern plateau-fringe and coastal plain; Malda to the middle Gangetic plain and Barind uplands; and Jalpaiguri to the sub-Himalayan plains, the Dooars and the Darjeeling Himalaya. In August 2022 the state cabinet approved in principle the creation of seven additional districts (Ichhamati, Basirhat, Sundarban, Bishnupur, Jangipur, Berhampore and Ranaghat), which would raise the total to thirty. These had not been formally constituted as of late 2025.

Agriculture

The cropping calendar follows three seasons: kharif (June to October), rabi (November to March) and zaid (April to May, often subsumed into the boro rice season). Rice (dhan) is the keystone crop and is grown in three seasonal forms. Aus is the autumn or pre-kharif rice, sown in March and April and harvested between June and August; once a major crop, its area is now substantially reduced. Aman is the winter or kharif rice, sown in June and July and harvested in October and November; this is the principal rice crop. Boro is the summer or rabi rice, sown in January and February and harvested in April and May; it is high-yielding-variety and irrigation-dependent. Total state rice output exceeds 16 million tonnes per annum, of which boro accounts for about 4.7 million tonnes.[12]

West Bengal is the largest producer of jute in India and accounts for about three-quarters of national raw jute output. Production is concentrated in Murshidabad, Nadia, Hooghly, North 24 Parganas, Cooch Behar, Bardhaman and Malda. About sixty of the country's seventy jute mills line the Hooghly.[13] Tea is the principal hill and Dooars crop. Darjeeling tea (sinensis-type, geographical indication) covers about 17,500 ha across some 87 estates. The Terai and the Dooars grow Camellia assamica on about 97,280 ha, processed as CTC. The state supplied 424 million kg of India's 1,390 million kg national output in 2019, or 30.5 per cent of national tea production.[3] Potato is concentrated in Hooghly and the Bardhaman districts. West Bengal is the second-largest producer in India after Uttar Pradesh, contributing about 22.8 per cent of national output.[14] Other significant crops by zone include wheat, oilseeds and pulses (rabi, on the middle Gangetic plain); mango, litchi and mulberry (Malda, Murshidabad and Nadia); pineapple (Siliguri and Jalpaiguri); coconut, betel and brackish-water aquaculture (South 24 Parganas, Purba Medinipur and Howrah); and tasar silk, niger, horse-gram and hardy millets on the lateritic west (Purulia and Bankura).

Demographic and ethnographic geography

At the 2011 Census, West Bengal had a population of 91,276,115 in 88,752 km², a density of 1,028 persons per km² and the second highest among Indian states.[11] The mother-tongue distribution was Bengali 86.22 per cent, Hindi 5.00 per cent, Santali 2.66 per cent, Urdu 1.82 per cent and Nepali 1.26 per cent.[15] Nepali is co-official in the Darjeeling and Kalimpong districts. Hindi, Odia, Punjabi, Santali, Urdu (2012) and Kamtapuri, Kurmali and Rajbanshi (2019) have additional official status in blocks where speakers exceed ten per cent. Telugu was added in 2020.

Scheduled Tribes constituted about 5.8 per cent of the state's population at the 2011 Census. Forty communities are notified. The dominant groups are the Santal (about 52 per cent of the ST population), Oraon (14 per cent), Munda (7.8 per cent), Bhumij (7.6 per cent) and Kora (3.2 per cent). These are concentrated in the southwestern plateau-fringe districts (Purulia, Bankura, Jhargram and Paschim Medinipur) and in the Dooars tea-garden belt (Jalpaiguri and Alipurduar), where many were brought as labour from Chota Nagpur in the late nineteenth century.[16] Other communities include the Lodha and Kheria of Jhargram and Paschim Medinipur (notified PVTG); the Toto of Totopara in Alipurduar (notified PVTG; 1,387 individuals at the 2011 Census, rising to about 1,600 by 2022); the Birhor of Purulia (notified PVTG); the Rabha, Mech and Garo of the Dooars and Terai; the Lepcha, Bhutia, Sherpa, Tamang and Limbu of the Darjeeling and Kalimpong hills; and the Rajbanshi of the North Bengal plains, whose linguistic identity is registered under the Kamtapuri / Rajbanshi heading. The Gorkha (Nepali) community of the Darjeeling and Kalimpong hills is not Scheduled but has shaped the political and administrative history of the hill region through long-standing autonomous-region claims.

The Santal community is the one most extensively recorded in colonial and post-colonial ethnographies of Bengal ganja cultivation, in the historical Ganja Mahal (where Santal women's role in the post-harvest processing is documented by Rahman, Matsushima, Uddin and Sarwar)[17] and across the Indian Rarh.

Cannabis in West Bengal

History

Pre-Colonial Period

Pre-colonial Bengali cannabis culture is documented across four chronological horizons whose evidentiary weight differs substantially. The Vedic and Sanskrit-lexicographic mentions of bhaṅga from c. 1200 BCE onwards are genuinely ambiguous in their botanical identification; the classical Āyurvedic compendia in their earliest layers do not securely attest cannabis as a medicine or intoxicant; the first irrefutable Indian medical attestation appears in an 11th-century Bengali text; and the dense documentary record of Bengali devotional, sectarian and culinary cannabis use consolidates only under the Sultanate, Mughal and early Nawabi regimes between c. 1500 and 1790.[18][19][20] The popular framing of cannabis as a "5,000-year-old" Indian sacrament collapses these horizons, and the present section follows Meulenbeld (1989), Wujastyk (2002) and Sauthoff (2024) in keeping them distinct.

Sanskrit textual and medical tradition

The earliest text routinely cited as evidence for ancient Indian cannabis is Atharvaveda 11.6.15 (conventionally c. 1200–1000 BCE), which names bhaṅga among five auspicious herbs said to release the worshipper from anxiety.[21] The 14th-century commentator Sāyaṇa glosses bhaṅga here as a kind of wild grass rather than Cannabis sativa specifically and modern scholarship treats the Atharvavedic reference as etymologically related to but botanically distinct from the later cannabis identification.[18][19] Pāṇini's Aṣṭādhyāyī (c. 4th century BCE) and the Amarakoṣa (c. 5th–6th century CE) contain the form bhaṅgā without botanical specification; identification with cannabis in these lexical sources requires reading later certainty back into them.[18]

The widely repeated claim that the Suśruta Saṃhitā (c. 3rd–4th century CE in its standard recension) prescribes cannabis as an antiphlegmatic derives from G.A. Grierson's note prepared for the IHDC.[22] Grierson himself, however, observed that vijayā in the relevant Suśruta passages was probably haritakī (yellow myrobalan) rather than hemp; Meulenbeld's 1989 study established that the cannabis passages in Suśruta and Caraka belong to disputed later strata of those texts and cannot bear the evidentiary weight assigned them.[18][22]

The earliest irrefutable Sanskrit medical attestation of cannabis as an ingestible intoxicating medicament is a Bengali text. The Cikitsāsārasaṃgraha of Vaṅgasena, a physician working in Bengal in the late 11th century CE whose name itself encodes Bengali origin (vaṅga = Bengal), recommends bhaṅgā as a digestive and appetiser, includes it in the powdered formula jātīphalādi cūrṇa for rājayakṣma (tuberculosis/consumption) and gives a rejuvenative recipe in which one who daily consumes indrāśana ("Indra's food," i.e. cannabis) with milk and sugar becomes free from all diseases and long-lived.[23][19] The compendium circulated widely in the Pāla–Sena and post-Sena Bengali medical milieu and represents the first secure point at which cannabis enters the Indian medical record.

A near-contemporary Bengali figure, Cakrapāṇidatta of the Pāla court of Nayapāla (mid-11th century), compiled the medical vocabulary Śabdacandrikā listing for cannabis the synonyms vijayā ("the victorious"), trailokyavijayā ("victorious in the three worlds"), bhaṅgā, indrāśana and jayā. The semantic field of this synonym set was the earliest in the Indian record strongly to imply that the intoxicating use of the plant was already recognised.[22][19] The Ānandakanda, a Sanskrit rasaśāstra–Tantric alchemical work dated to the 12th–13th century, devotes most of its chapter 15 (some 186 verses) to vijayā, covering cultivation, sowing and harvest mantras, male and female plants, purification, nine stages of intoxication and an elaborate rejuvenation treatment (kuṭīpraveśika rasāyana) involving prolonged consumption in a specially constructed hut.[20] The Śārṅgadhara Saṃhitā (c. late 13th–early 14th century) became the first classical compendium to classify bhaṅgā as vyavāyin (a quick-acting drug that pervades the body before being absorbed) and to pair it explicitly with ahiphena (opium).[24] Later compendia and nighaṇṭus, including the Dhanvantari Nighaṇṭu, Madanapāla Nighaṇṭu (1374), Rāja Nighaṇṭu of Narahari Paṇḍita (14th century) and the Bhāvaprakāśa of Bhāvamiśra (16th century), extend the synonym lists and indications and were the standard reference works of Bengali kavirājas by the late medieval period.[25]

Tantric textual emergence

Bengal was the heartland of Vajrayāna Buddhism under the Pāla dynasty (c. 750–1174 CE), which patronised the great monastic universities of Nālandā, Vikramaśīla, Odantapurī, Somapura (Pāhāḍpur) and Jagaddala. The wandering mahāsiddhas of this milieu composed the Caryāpada (চর্যাপদ), the oldest extant corpus of Old Bengali verse, datable to between the 8th and 12th centuries; forty-seven verses survive in the palm-leaf manuscript recovered by Haraprasad Shastri from the Nepal Royal Court Library in 1907.[26] The Caryāpadas are composed in sandhābhāṣā (intentional language). Although their imagery includes brewing and intoxication, no extant verse explicitly names cannabis: the substance consistently invoked is madya (liquor). Cannabis use among Bengali tantric adepts is, however, securely attested in other Pāla-era and immediately post-Pāla sources: Nāgārjuna's Yogaratnamālā (12th century) recommends cannabis smoke in tantric ritual contexts[18] and the Tārā Tantra edited by Akshay Kumar Maitra references its tantric use directly.[27] Aldrich (1977) traces continuous Indian tantric cannabis use to roughly this horizon, which represents the first secure rather than speculative attestation.[28]

The Bengali Śākta Tantric tradition was codified between the 11th and 18th centuries in the Mahānirvāṇa, Kulārṇava, Niruttara, Tārā, Kāmākhyā and other Tantras, several of which integrate cannabis directly into prescribed ritual. The Mahānirvāṇa Tantra, a Bengal text whose extant recension is generally treated as late 18th- or early 19th-century, was first published by the Adi-Brahma-Samaj in 1798 Śakābda (1876 CE) with the commentary of Hariharānanda Bhāratī.[29]

Early-modern documentation and Mughal context

The earliest detailed European description of bhang in South Asia is in Garcia da Orta's Colóquios dos simples e drogas e cousas medicinais da Índia (Goa, 1563), in the dialogue "Do bangue, Cannabis," which distinguishes the substance from European hemp and describes preparation of the leaf and seed into a powder mixed into drink with optional additions of areca, opium, cloves and nutmeg.[30] Jan Huyghen van Linschoten's Itinerario (Amsterdam, 1596) explicitly identifies bhang use in Bengal.[31] Thomas Bowrey's A Geographical Account of Countries Round the Bay of Bengal, 1669–1679 is widely regarded as the earliest detailed English-language account of cannabis use in coastal Bengal, describing East India Company sailors at Bālāsore experimenting with bangue.[32] Niccolao Manucci's Storia do Mogor, François Bernier's Travels in the Mogul Empire (covering his 1665–66 journey to Bengal) and Jean-Baptiste Tavernier's Voyages (covering Dhaka and Hooghly) attest post (cold opium infusion), bhāṅ and maʿjūn at the Mughal court and in Bengal sūbah towns.[33][34]

Abu'l-Faẓl's Āʾīn-i Akbarī (c. 1590) refers to bhāṅ, post and opium among recreational intoxicants and gives the rent-roll of Bengal's nineteen sarkārs, but does not itemise a separate gāñjā or bhang revenue line.[35] Mughal and Nawabi intoxicant taxation in Bengal sūbah was subsumed within the catch-all sāyer (miscellaneous non-agrarian) revenue and the ābkārī (literally "distiller's") tradition, administered by local zamindars and ijāradārs under broad farming-out arrangements that the 1793 Cornwallis-era licensing inherited directly.[36] Raja Soshi Sikhareshwar Roy of Tahirpur (Rajshahi), in his note of dissent to the IHDC, argued explicitly that under Mughal rule the hemp drugs had never before been taxed as a separate excise.[36] By the late 18th century the tract that the British would formalise as the Ganja Mahal, covering parts of Naogaon, Rajshahi, Bogra and Dinajpur with secondary nodes in Jamalpur, Netrokona and the hilly Chittagong tract, was already the principal Bengali production zone.[37]

Cultivation in pre-colonial Bengal was concentrated on the alluvial flats of the lower Ganges-Brahmaputra delta and the Padma-Atrai basins of northern Bengal, the future Ganja Mahal. Consumption was densest in (a) the urban-mercantile centres of Murshidabad, Dhaka, Hooghly and, after 1690, Calcutta, where Mughal-Nawabi court use of maʿjūn, post and bhāṅ set patterns subsequently adopted by Bengali bhadralok households; (b) the Śākta pilgrimage circuit of Tārāpīṭha, Kālīghāṭ, Bakreśwar and the śmaśāna-shrines of the Rāḍh region; (c) the Śaiva centres, especially Tārakeśwar and Baidyanāth; and (d) the rural countryside of Birbhum, Murshidabad, Nadia, Kushtia and Faridpur, the historic Bāul-Fakir heartland. Riverine ghat-side preparation of bhang and siddhi, pounding on a stone slab beside the river, was a near-universal pre-colonial practice across the delta. The wild Himalayan plant of the upland north had little role in pre-colonial Bengali culture, which depended throughout on cultivated lowland material.

Distinguishing secure from speculative attestation

For the purposes of citation discipline, pre-colonial Bengali cannabis claims fall into three classes. Securely attested by primary sources before 1790: Sanskrit medical use from the 11th-century Bengali physician Vaṅgasena onwards; Bengali Tantric Śākta consecration of vijayā in the Mahānirvāṇa and related Tantras; European traveller reports of bhang in Bengal (Linschoten 1596; Bowrey 1669–1679; Bernier; Tavernier; Manucci); Mughal court familiarity with bhāṅ, post and maʿjūn (Āʾīn-i Akbarī, c. 1590); and cultivation in the future Ganja Mahal tract by the late 17th–18th century. Securely attested only in 19th-century retrospective documentation, but with strong continuity arguments to the pre-1790 period: the Bijoyā Daśamī siddhi offering as universal Bengali household custom; Śivarātri bhang at Tārakeśwar; Bāul-Fakir cannabis use; the figure of the gā̃jākhor in Bengali folklore; and the term siddhi as the name for the drinkable preparation. Speculative or back-projected: the Atharvaveda-as-proof-of-Vedic-cannabis reading, which depends on a botanical identification Sāyaṇa himself did not make; the Suśruta Saṃhitā as a confident early cannabis source, which Grierson and Meulenbeld both rejected on textual-strata grounds; and "5,000-year-old timeless Hindu cannabis sacrament" narratives, which are largely 20th-century reframings of textually unstable evidence.[18][19][20]

Colonial Period

Under British colonial rule, the Bengal Presidency (which at various points included present-day West Bengal, Bangladesh, Bihar, Odisha and Assam) was the administrative, commercial and scholarly centre of the Indian cannabis economy. Calcutta, the Presidency capital, housed the Excise Department that regulated the trade; the Bengal Secretariat Press that published its foundational documents; the Asiatic Society of Bengal and the Calcutta Botanic Garden where its scientific study was conducted; and the wholesale and financial infrastructure through which the trade passed. The licensed cultivation belt, however, lay entirely north of the Ganges in what is now Bangladesh and was severed from West Bengal by the Partition of 1947.

The first formal British taxation came in 1790, when duties on alcohol and intoxicants were levied on landlords across the Presidency.[38] Regulation XXXIV of 1793, part of the Cornwallis Code, required a licence from the district collector for the manufacture or sale of bhang, ganja, charas and other intoxicating drugs.[38] Pre-monopoly cultivation was scattered across zamindari estates, with the Jessore tract in the southern Presidency reportedly producing some 2,000–2,400 tons annually before its suppression in 1875 and the consolidation of licensed cultivation northward to the Naogaon area of Rajshahi district.[37]

By the 1850s licensed cultivation had been consolidated into the Ganja Mahal, a small geographical zone astride the Rajshahi, Bogra and Dinajpur districts of the northern Presidency, with its headquarters at Naogaon. The Mahal was worked under a three-circle rotation in which each circle was permitted to grow ganja once every three years, with manufactured product held in licensed warehouses (golas) under Excise Department supervision and duty levied at point of issue.[17] The administrative foundation of the system was Hem Chunder Kerr's Report on the Cultivation of, and Trade in, Ganja in Bengal (Calcutta: Bengal Secretariat Press, 1877), and the cultivators were organised from 1917 as the Naogaon Ganja Cultivators' Cooperative Society Limited.

The Indian Hemp Drugs Commission (IHDC) was appointed by Resolution of 3 July 1893 following a question in the House of Commons by William Sproston Caine MP requesting an enquiry into the cultivation and trade of hemp drugs in Bengal specifically.[39] The seven-member Commission first met in Calcutta on 3 August 1893 and conducted much of its work from the Presidency capital; one of its three Indian members was Raja Soshi Sikhareswar Roy of Tahirpur, a major zamindar in the Rajshahi cultivation belt.[40] Volume IV of the seven-volume report is devoted to the evidence of Bengal and Assam witnesses and constitutes the densest body of named Bengali testimony in any colonial-era source on cannabis. The Commission found that the moderate use of hemp drugs produced no injurious effect on the mind, rejected prohibition and recommended that the Bengal regulatory model be extended to other provinces.

The Radcliffe Line of 1947 placed the entirety of the cultivation tract, together with the Ganja Society's Naogaon headquarters, in East Pakistan. West Bengal retained the consumption markets, the Calcutta wholesale infrastructure, the urban retail vending network and the Bengal Cooperative Bank deposits of the Naogaon Society, but lost the licensed cultivation belt entirely.[41]

Preparations and Consumption

By the period when documentation becomes dense (16th–18th centuries) three distinct Bengali cannabis preparations are clearly differentiated. These categories were subsequently formalised for colonial excise purposes and consistently distinguished across the witness questions of the IHDC.[40]

Ganja (গাঁজা) was the flowering tops of the female plant. In pre-colonial Bengal the "rolled or Bengal type" was regarded as of higher quality than the "trodden or Bombay type" and was preferred for medicinal use, smoked in a cilam often with the invocation of Śiva.[42] Under the colonial excise system the Ganja Mahal manufactured ganja in three product types. Flat ganja (chyapta, চ্যাপ্টা) was produced by pressing cut tops flat under foot on the manufacturing platform (chatar, চাতার). Round ganja (gol ganja, গোল গাঁজা; long and short-stalked) was rolled between the hands or under the foot into cylindrical or oblong form, with long-stalked round ganja commanding the highest price. Chur ganja (চুর গাঁজা) was the resinous fragments and debris collected from the chatar floor.[43]

Bhang (ভাং) was the leaves and seeds of the plant, ground and consumed as a drink (known in Bengali as siddhi, সিদ্ধি) or worked into the sweet confection majoon (majun, মজুন). The pre-colonial drinkable preparation was produced by soaking dried leaves and flowering tops, grinding them on a stone slab with sugar, milk and the ṭhāṇḍāi spice matrix (black pepper, cardamom, fennel, cucumber seed, almond, rose petals) and straining the mixture into milk. The dry leaf material itself was also called siddhi and was sold at Bengali Hindu ritual-supply shops (daśakarmā-bhāṇḍār). No securely pre-1790 Bengali manuscript using the exact word siddhi in the drinkable cannabis sense has yet been published in translation, but the practice itself is plainly implied by Vaṅgasena's 11th-century milk-and-sugar recipes.[23] Majoon, the sweetened cannabis confection inherited from Persian-Mughal pharmacy, combined bhang paste with ghee, flour, sugar, often poppy seed and at times opium, nutmeg or Datura metel. It was sold widely "at festivals and other great gatherings of the brethren."[38] Under the colonial excise system bhang was sold through licensed government bhang shops, a vending category that has continued in West Bengal into the present day.

Charas (চরস) was collected resin. Its manufacture and sale was prohibited in 1800 "as being of a most noxious quality" but the restriction was rescinded in 1824 on the ground that the drug was "not more prejudicial to health than ganja or other intoxicating drugs."[38] Charas was never produced in Bengal in commercial quantity but was imported from the northwest (principally Yarkand and Punjab) and sold under the same excise framework.


Religious and Cultural Use

Stub
This section is incomplete. Add sources and expand it.

Cannabis use in Bengal is documented across multiple religious traditions in colonial-era sources, with the densest evidence in Volume IV of the IHDC (1894). The Commission's seventy standardised witness questions included extensive enquiry into religious and ritual use and the Bengal evidence covered Shaiva and Shakta worship in the Shiva–Kali–Durga complex; charanamrita and prasad offerings at temple sites; and use among Vaishnava bairagi and Baul mendicants.[40] The clearest pre-colonial documentation is reconstructed from late 18th- and 19th-century sources looking back and from IHDC chapter IX, which collected sworn evidence on customs whose roots witnesses described as immemorial.[44]

Tantric ritual practice. The Bengali Śākta Tantric tradition codified between the 11th and 18th centuries in the Mahānirvāṇa, Kulārṇava, Niruttara, Tārā, Kāmākhyā and other Tantras integrated cannabis directly into ritual. The Mahānirvāṇa Tantra explicitly directs the sādhaka to consecrate vijayā before consumption, with the vijayā-consecration mantra invoking ambrosia and the favour of Kālikā.[29] The pun between siddhi as yogic attainment and siddhi as cannabis preparation is structural in Bengali Śākta usage. In the formal scheme of the pañcamakāra of the Bengali Śākta vāmācāra tradition (madya or wine, māṃsa or meat, matsya or fish, mudrā or parched grain and maithuna or sexual union), cannabis is not one of the canonical five but functions as a substitute or adjunct to madya in many kaula and bhairavī-cakra lineages.[45] White (2003) treats this substitution as continuous with the older soma-offering pattern reinterpreted in tantric idiom.[46] The Sahajiyā lineages, comprising the older Buddhist sahaja-siddha tradition and the Vaiṣṇava Sahajiyā that emerged from Caitanyaite milieus after the 16th century, inherited the emphasis on deha-tattva ("body-truth") and on intoxicants as adjuncts to sādhanā, though explicit textual record of cannabis use among Sahajiyās before 1790 is thin and is reconstructed largely from later Bāul songs and from ethnographic continuity arguments.[47]

Devotional and festival use. On Bijoyā Daśamī, the tenth day of Durgā Pūjā, the IHDC found that the custom of offering an infusion of hemp leaves to every guest and household member was common in Bengal and "may almost be said to be universal."[44] Witnesses including Mahāmahopādhyāya Maheśa Chandra Nyāyaratna, Principal of the Government Sanskrit College, Calcutta; Maharaja Sir Jyotīndramohan Tagore, K.C.S.I.; and Raja Piari Mohan Mukharji, C.S.I., attested its prevalence and its association with the religious devotions of the people. After the household consigned the goddess's image to the river, the bijoyā siddhi-cup was passed and bhang-laced sweetmeats were distributed.[44] On Śivarātri the Commission established that the hemp plant, especially gāñjā, was most strongly associated with the worship of Śiva, in popular belief a favourite of the god. Siddhi was offered to the Śiva image at Benares, Baidyanāth, Tārakeśwar and elsewhere.[44] At Tārakeśwar in Hooghly district, the major Bengali Śaiva pilgrimage centre whose temple in its present form was established in 1729 by Raja Bharamalla Rao,[48] pouring bhang-water over the liṅga on Śivarātri night was the normative ritual act. Cannabis at the spring festival of Dol Yātrā / Holi is attested across Bengal in IHDC testimony, paired in the Bengali calendar with the Vaiṣṇava swing-festival of Caitanya's birthday on Phālgun pūrṇimā.[44]

The Śākta pilgrimage circuit. The Bengali Śākta circuit comprising Kālīghāṭ (one of the fifty-one śakti pīṭhas, in present-day Kolkata), Bakreśwar, Kankalitala and especially Tārāpīṭha in Birbhum district on the Dvārakā river (one of the principal śmaśāna-Tārā shrines of Bengal) constituted the canonical pre-colonial setting for Tantric cannabis offerings, with gāñjā smoked in the cilam and siddhi consumed as drink by sādhakas at the cremation-ground sādhanā.

Folk and mendicant traditions. The Bāul-Fakir lineage, a syncretic Vaiṣṇava-Sahajiyā / Sufi-Fakir minstrel tradition concentrated in Kushtia and Shilaidaha in East Bengal and in Murshidabad, Birbhum and Nadia in West Bengal, emerges into the textual record from the 15th century, though as an organised sect it is securely documented only from the 18th. Bāuls and Fakirs treated gā̃jā, bhāṅ and siddhi as sādhanā-adjuncts in a usage structurally identical to their Tantric Śākta deployment.[49][50] The Bāul association with cannabis is most famously linked to Lālan Fakir (Lālan Śāh, 1774–1890), but the pattern predates him in the 17th- and 18th-century Vaiṣṇava-Sahajiyā poetic corpus. The wider category of the gā̃jākhor ("gañjā-eater" or "gañjā-smoker") in Bengali folklore covers Śaiva sādhus, bairāgīs, nāgā ascetics, aghorīs, fakirs and jaṭā-sporting wanderers passing through Bengal en route to Puri, Tārāpīṭha, Kāmākhyā or Hardwar. The Commission found that supplying gañjā to such mendicants was treated by Bengali householders as a routine act of religious charity.[44] The Sāntal, Munda, Oraon and other ādivāsi populations of western Bengal (Birbhum, Bankura, Purulia and the Chota Nagpur fringe) had their own distinct ethnobotanical relations to cannabis, with Sāntal medicinal uses for epilepsy, tetanus, paralysis and fever-delirium reflecting traditions reaching back into the pre-colonial period.[51]


Trade and Commerce

Calcutta was the financial and wholesale back-end of the colonial Bengal cannabis economy. Wholesale dealers (mahajans) converged on the Ganja Mahal during the January–April marketing season to buy product directly at the gola, taking dispatches under transport permit by river, by road and (from the 1870s) by the Eastern Bengal Railway. Distribution centres across the Presidency included Dhaka, Pabna, Khulna, Jessore, Chittagong, Comilla, Mymensingh, Barishal and Sylhet, with overland routes to the United Provinces, Bihar and the Central Provinces.[37] Smuggling into Lower Burma, where cultivation, sale and possession had been prohibited under the Burma Excise Act of 1873, was a continuing concern of the colonial excise administration. Smaller export movements to indentured-labour destinations (Trinidad, Guyana, Fiji, Natal) and to British and American pharmaceutical houses for medical Cannabis indica preparations are documented in the India Office Records.[36]

The Naogaon Ganja Society maintained pre-Partition assets in Calcutta, including a deposit at the Bengal Cooperative Bank that has never been recovered.[41]


Scholarship

Calcutta was the centre of colonial-era scientific and administrative scholarship on Indian cannabis. The Calcutta Botanic Garden under William Roxburgh conducted experimental trials of European fibre hemp on the Bengal plain from the 1790s through the 1810s, documented in Roxburgh's Further Extracts of Correspondence Relating to Indian Hemp; Between W. Roxburgh and R. C. Plowden (Calcutta, 1810). The trials were unsuccessful for fibre purposes but established the Garden's role as a centre for cannabis botany.

The pharmacological introduction of Cannabis indica to Western medicine was conducted in Calcutta by the Irish physician William Brooke O'Shaughnessy, Professor of Chemistry at the Medical College of Bengal, whose 1839 paper "On the Preparations of the Indian Hemp, or Gunjah" (Transactions of the Medical and Physical Society of Bengal, Calcutta) and 1843 monograph established the medical use of cannabis tinctures in British and American pharmacy through the second half of the nineteenth century.

The Asiatic Society of Bengal in Calcutta published botanical, ethnographic and pharmacological work on cannabis throughout the nineteenth century in its Journal and Proceedings. George Watt's Dictionary of the Economic Products of India (Calcutta: Superintendent of Government Printing, 1885–93, 6 vols), of which the cannabis entry occupies vol. II, pp. 103–149, drew extensively on Asiatic Society material and on Hem Chunder Kerr's 1877 report and was itself laid before Parliament in 1893 as a foundational document for the IHDC enquiry.

The Bengal Secretariat Press in Calcutta published Kerr's 1877 report, all of the Bengal District Gazetteers (including L.S.S. O'Malley's Rajshahi volume of 1916 with its dedicated chapter on the Ganja Mahal) and successive editions of the Memorandum on Excise Administration in India so far as it is concerned with Hemp Drugs. The IHDC first met in Calcutta on 3 August 1893 and its Secretary, H.J. McIntosh, was Under-Secretary to the Government of Bengal in the Financial and Municipal Departments.[40]
