How British Hemp Demand Reshaped Colonial India's Economy

Rope won empires before oil did. Every ship the Royal Navy sailed and every merchant vessel that carried tea, opium, or textiles between London and Calcutta depended on tens of thousands of yards of hemp cordage, canvas sail, and netting. Lose the hemp supply and you don't lose a commodity -- you lose the ability to project power across water at all. That's precisely what happened in 1800, when Russia, then Britain's near-total supplier of naval hemp, shut its ports to English buyers in the middle of the Napoleonic wars. Britain needed a new source fast, and colonial India, already growing cannabis for fiber, food, and its own longstanding intoxicant trade, became the answer London's Admiralty and East India Company officials reached for.

What followed wasn't simply an agricultural substitution story of one hemp field replacing another. British administrators in India found themselves managing two entirely different cannabis economies at once -- one built around fiber for rope and canvas, the other around bhang, ganja, and charas, intoxicant preparations already woven into Indian commerce, religious practice, and daily life long before any English official arrived. Rather than choosing between exploiting the crop and suppressing the drug trade, colonial administrators built parallel bureaucracies for both, taxing and licensing rather than banning outright. That regulatory instinct -- control through revenue rather than prohibition -- didn't disappear with independence in 1947. It persisted, largely intact, until 1985, and its fingerprints are still visible in how India draws the line today between illegal cannabis flower and resin and perfectly legal bhang shops selling leaves by the roadside.

Why the Royal Navy Needed India's Fields

To understand why India mattered so much to British hemp policy, it helps to remember what hemp actually did for a maritime empire. Rope, sailcloth, canvas, and fishing nets all ran on it, and a wooden warship of the era was essentially a hemp-rigged machine held together by tar and cordage. Historians have compared its strategic weight to oil in the twentieth century -- lose access to it, and your navy stops moving. England had understood this for centuries. Henry VIII's 1533 statute actually mandated hemp cultivation on English estates, fining landowners who refused to plant it, and Elizabeth I tightened those penalties further as the fleet grew and the stakes rose.

Despite home-grown mandates, England never produced enough hemp to satisfy its own navy, so it leaned on imports almost entirely from Russian territories around the Baltic. In the fifteen years before 1800, Britain imported an average of roughly 26,000 tons of hemp annually from Russia -- a staggering dependency for a nation whose global reach rested on that very fiber. When Tsar Paul I permanently severed hemp exports to Britain in 1800 amid the Napoleonic conflict, it wasn't a minor trade dispute. It was a supply-chain emergency that threatened the Admiralty's ability to keep ships seaworthy.

London's response was immediate and organized. A government committee formed that same year with one explicit task: locate new hemp sources across the empire, and India, already cultivating cannabis widely, rose to the top of the list alongside other colonial territories. The math behind the urgency was blunt -- roughly 200 tonnes of rope and sailcloth needed renewal every two years just to keep the existing fleet functional, without accounting for the new ships that would themselves need to be built and rigged to haul Indian hemp back to English ports. Demand fed demand, and India's fields suddenly carried imperial weight.

Taxing Bhang, Ganja, and Charas: Britain Builds a Drug Bureaucracy

While naval planners fretted over fiber, a different discovery was unfolding among East India Company administrators on the ground: India already had a mature, commercially significant cannabis trade that had nothing to do with rope. Bhang, ganja, and charas were bought, sold, taxed informally, and consumed across the subcontinent through networks of cultivation and trade that long predated British involvement. Rather than treating this as a problem to eliminate, colonial officials treated it as a problem to capture -- specifically, as an untapped revenue stream.

The first formal move came in 1790, when Britain levied duties on intoxicant drugs charged directly to Indian landlords. It wasn't a moral crusade against the substance; it was a straightforward fiscal decision to extract income from a trade that was already thriving with or without English approval. Three years later, Regulation XXXIV of 1793 went further, requiring anyone who wanted to manufacture or sell bhang, ganja, or charas to first obtain a license from the district collector. The regulation's own stated purpose was double-edged: checking what officials called immoderate consumption while simultaneously augmenting public revenue. Those two goals sat side by side without much apparent tension in the colonial mind.

By 1800, the same year the Admiralty was scrambling over rope, Indian administrators carved out one exception to the tax-and-license approach. Charas -- the resin form of cannabis -- was banned outright as a substance officials described as being of a most noxious quality, even as bhang and ganja remained legal under fixed daily duty rates. That distinction between resin and other cannabis preparations, drawn for administrative convenience over two centuries ago, still echoes in Indian law today. What emerged from these early decades was a governing logic that would define British cannabis policy in India for the next hundred years: don't suppress the trade, license it, tax it, and let revenue do the regulating.

The Indian Hemp Drugs Commission of 1893-94

By the 1890s, that century-old licensing system faced its first serious institutional scrutiny. On 2 March 1893, members of the House of Commons in London raised pointed questions about the effects of hemp drugs in Bengal, pressuring the Government of India to formally investigate what its own tax-and-license regime had produced. The response was the Indian Hemp Drugs Commission, convened on 3 July 1893 with seven members and an initial mandate limited to Bengal -- though Lord Kimberley, then Secretary of State for India, suggested expanding its scope to cover all of British India, and that broader mandate stuck.

The Commission's fieldwork was genuinely exhaustive by the standards of the era. Members first met in Calcutta on 3 August 1893 and continued working until 6 August 1894, spending over a year traveling and gathering testimony. In total, they interviewed 1,455 witnesses across thirty cities spanning eight provinces plus Burma, holding eighty-six separate examination meetings -- physicians, cultivators, revenue officials, religious figures, and ordinary consumers all had their testimony recorded and weighed.

The final report's conclusion was, in retrospect, entirely consistent with the colonial instincts already in place since the 1790s: control cannabis through taxation, licensed cultivation, and limits on possession and sale, rather than move toward prohibition. Bengal's existing administrative apparatus was held up explicitly as the model other provinces should adopt. Not every commissioner agreed. Two Indian members, including Raja Soshi Sikhareshwar Roy of Tahirpur, dissented sharply, arguing for outright prohibition and noting -- pointedly, and not without justification -- just how much revenue the British administration had already extracted from the hemp drug trade over the preceding century. Their objection was overruled by the majority, and the regulate-and-tax framework held for nearly another hundred years.

From Colonial Ledger to the NDPS Act

What the 1893-94 Commission settled on didn't just survive the following decades -- it essentially became the permanent operating system for Indian cannabis policy well past independence. For nearly a century, the core mechanics barely changed: license cultivation, tax sale, restrict resin more tightly than other preparations, and let provincial administrations manage the details locally. It was a system built for colonial revenue extraction, but newly independent India inherited it largely intact simply because no domestic political pressure existed to overhaul it.

That changed under external pressure rather than internal reform. As international drug control conventions hardened through the twentieth century -- particularly the 1961 Single Convention on Narcotic Drugs, which India had been slow and reluctant to fully align with -- diplomatic and treaty obligations pushed New Delhi toward a stricter national framework than the old licensing regime could provide.

The result was the Narcotic Drugs and Psychotropic Substances Act of 1985, which marked the first genuine break from the colonial model. The NDPS Act criminalized the cultivation, sale, and possession of cannabis resin and flower nationwide, replacing over a century of provincial licensing discretion with a uniform criminal framework backed by national enforcement.

What's easy to miss, though, is what the NDPS Act left out. The statute explicitly excludes cannabis leaves and seeds from its criminal provisions -- which is precisely why bhang shops remain legal fixtures in many Indian states, selling bhang-based drinks and preparations openly, particularly around festivals like Holi and Shivratri. That exclusion isn't a modern loophole invented by lawmakers in the 1980s. It's a narrowed, updated version of the same product-by-product distinction British administrators drew back in 1800 when they banned charas outright while leaving bhang and ganja under lighter, taxable regulation. The categories changed shape, but the underlying administrative habit of splitting cannabis into differently regulated tiers never really left.

Hemp's Return as an Economic Crop

The most recent chapter in this story looks, on the surface, like a return to where it all started -- India once again treating cannabis primarily as a fiber and industrial crop rather than a controlled substance. After decades under the NDPS Act's restrictive framework, several state governments have begun licensing industrial hemp cultivation as a legitimate agricultural product in its own right, separate from the criminalized flower and resin trade.

Uttarakhand moved first, launching an industrial hemp cultivation program in 2018 that stands as one of the earliest state-level efforts of its kind in post-independence India. The program focused on low-THC hemp varieties grown for fiber and seed, licensed and monitored by the state rather than left to informal cultivation. Himachal Pradesh followed with its own state hemp cultivation pilot launched in 2025, signaling that Uttarakhand's experiment wasn't an isolated case but the start of a broader trend among state governments willing to test industrial hemp as a cash crop under controlled licensing.

What's notable about these programs is how closely their stated purpose mirrors British colonial priorities from over two centuries earlier -- fiber, seed, and industrial uses, not psychoactive consumption. Where the East India Company wanted hemp for naval rope and canvas, today's state programs are targeting textiles, construction materials, and food-grade seed products, but the underlying regulatory move is strikingly similar: carve cannabis grown for industrial purposes out from cannabis grown or sold as an intoxicant, and license the former separately and more permissively.

That regulatory split, between industrial hemp on one side and controlled cannabis on the other, isn't a novel policy invention of the 2020s. Its administrative DNA traces directly back to distinctions British officials first drew in the 1790s, when they separated licensed bhang and ganja from banned charas, and reinforced in the 1890s, when the Hemp Drugs Commission built an entire regulatory philosophy around controlling different cannabis products differently rather than treating cannabis as a single, undifferentiated substance.

Strip away the dates and committee names, and what's left is a fairly simple pattern: the British Empire never saw Indian cannabis as one thing. It was simultaneously a raw material essential to naval survival and a taxable vice embedded in local custom, and rather than resolve that tension, colonial administrators just built two separate bureaucracies to manage each side of it. Both outlasted the empire that created them, which is a more unusual legacy than it might first appear -- most colonial institutions get dismantled or renamed after independence. This one just kept running under new management.

Look at India's current cannabis patchwork -- resin and flower banned nationally under the NDPS Act, leaves and seeds left untouched and sold openly as bhang, individual states now licensing industrial hemp cultivation on their own initiative -- and it's tempting to read it as some kind of contemporary political compromise, cobbled together to satisfy competing modern interests. It largely isn't. It's a redrawn version of distinctions colonial administrators settled on well over a century ago, when they banned charas as noxious while taxing bhang and ganja, and when the 1893-94 Commission chose control over prohibition and left provincial governments to sort out the details.

That history is worth keeping in mind for anyone watching Uttarakhand's or Himachal Pradesh's hemp programs expand, or wondering whether more Indian states will follow. The same tension that ran through the 1893 Commission's hearings -- how much revenue to extract, how much control to exert, who gets the right to cultivate -- hasn't gone away. It's just wearing modern regulatory language instead of colonial administrative prose.
