When Rulers Sell Vice

A History of Manufactured Addiction

Guzalia Davis

Throughout history, one of the most reliable ways for a treasury in trouble to refill itself has been to control, promote, or quietly encourage the population's access to intoxicants. Alcohol, opium, tobacco, and now cannabis have each, at different moments, gone from being restricted, stigmatized, or rare, to being state-sanctioned or state-run industries, almost always at a moment of fiscal crisis. The pattern is consistent enough to be worth naming.

Russia: The Kabak System

Pre-Muscovite Russia had no strong drinking culture; mead and weak beer were consumed at feasts, not daily. That changed with Ivan IV ("the Terrible") in the 16th century, who established the kabak — a state-licensed tavern with a monopoly on vodka sales in its district. Kabaks became a direct arm of the treasury: local governors were assigned revenue quotas, and taverns were often forbidden from selling food alongside the alcohol, which increased both consumption speed and intoxication. Peasants could be pressured or even legally required to patronize the assigned kabak, and by the 17th and 18th centuries, vodka revenue (the vinnaya moneta) had become one of the single largest sources of state income in the Russian Empire, at times close to a third of total revenue. Reform-minded officials periodically tried to curb it (there were temperance riots in the 1850s-60s), but the state kept re-establishing the vodka monopoly whenever war or debt made cash urgent, most notably under Sergei Witte in the 1890s, explicitly to fund industrialization.

China: The Opium Wars

By the early 1800s, Britain ran a large trade deficit with China: British consumers wanted tea, silk, and porcelain, but China had little interest in British manufactured goods and would only accept payment in silver. The British East India Company solved this by growing opium in Bengal under monopoly and smuggling it into China in vast quantities through private traders, flipping the balance of trade in Britain's favor and turning millions of Chinese into opium users along the way. When the Qing government tried to suppress the trade (Commissioner Lin Zexu's 1839 destruction of opium stocks at Canton), Britain went to war to protect the trade, twice (the First and Second Opium Wars (1839–42, 1856–60)) winning both, extracting Hong Kong, forced treaty ports, and legalized opium imports. This is one of the clearest documented cases of a state weaponizing a population's addiction as a trade and revenue tool.

British India: The Opium Monopoly

Less discussed than the wars themselves is the machinery behind them: the British Raj ran opium as a direct state monopoly in Bengal, with peasant farmers compelled into poppy cultivation contracts, and the drug auctioned by the government in Calcutta. By the late 19th century, opium was the second-largest source of revenue for British India after land tax, and the government defended the monopoly against domestic and missionary critics for decades because the treasury depended on it.

French Indochina: The Opium Régie

The French colonial government in Vietnam, Laos, and Cambodia ran a formal opium monopoly (the Régie de l'Opium) from the 1880s into the 20th century. At its peak, opium sales funded roughly a third of the colonial budget. French administrators were known to resist anti-opium reform campaigns specifically because the colony's finances depended on steady consumption — a monopoly cannot survive shrinking demand, so it had structural reasons to avoid meaningfully discouraging use.

The United States: Prohibition's Repeal

American alcohol Prohibition (1920–1933) was overturned for several converging reasons, bootlegging, organized crime, unenforceability, but the fiscal argument was explicit and decisive. The federal government had leaned heavily on income tax after losing alcohol excise revenue in 1920, and by the depths of the Great Depression, with unemployment near 25% and tax receipts collapsed, legalizing and taxing alcohol again was pitched, openly, as a way to raise federal revenue without raising income taxes further. Franklin Roosevelt's campaign and early administration used exactly that argument, and the 21st Amendment (1933) was followed almost immediately by federal alcohol excise taxes that became a meaningful revenue stream during the recovery.

Colonial Sugar, Rum, and Tobacco

The broader Atlantic economy ran on a related mechanism: sugar plantations (worked by enslaved labor) produced molasses, which was distilled into rum, which colonial and metropolitan governments taxed heavily and used as currency in the slave trade itself. Tobacco played a similar dual role in the American colonies — a taxed export crop for the crown and, domestically, a good whose consumption authorities had little incentive to discourage once duties on it became a fiscal staple.

Cannabis: A Modern Parallel, and What It Actually Does to the Body and Mind

Cannabis in the U.S. followed the inverse path of most of the above, decades of criminalization followed by rapid, state-by-state legalization, but the fiscal logic is now explicit rather than hidden. States facing budget shortfalls have marketed legalization directly as a tax-revenue solution: dispensary excise taxes, licensing fees, and "It'll pay for schools/roads" campaign messaging have been central to nearly every state ballot initiative. Colorado, California, Illinois, and others now collect hundreds of millions of dollars a year in cannabis tax revenue, and once a state depends on that revenue line, it has the same structural incentive the French had with opium: shrinking consumption becomes a budget problem, not a public-health win.

Before lighting up the next joint, it's worth asking why something treated as a serious crime for most of the 20th century became a strip-mall storefront in the space of about a decade, and whose revenue line you're now a recurring entry in, whether that's a state treasury, a multi-billion-dollar cannabis industry, or both.

What the research actually shows about cannabis harms
(this is a genuinely researched area — some findings are well-established, others are still debated, and I'll flag which is which):
  • Adolescent cognitive impact. The most solid evidence concerns developing brains. Longitudinal studies (notably the Dunedin cohort in New Zealand) found that heavy, persistent cannabis use starting in adolescence was associated with IQ declines of several points by adulthood, and with impairments in memory, attention, and executive function — effects that were weaker or absent in people who started using only as adults.

  • Psychosis and schizophrenia risk. This is a real, dose-dependent statistical association, not a settled causal one. Large longitudinal studies (including Swedish conscript cohorts followed for decades) found higher rates of later schizophrenia diagnosis among heavy adolescent cannabis users, and cannabis use is associated with earlier onset and higher relapse risk in people who already have psychotic disorders. What remains debated is direction and mechanism — whether cannabis triggers psychosis in people already vulnerable (via genetic risk or family history), whether it's a marker rather than a cause, or both. It is not accurate to call cannabis a straightforward cause of schizophrenia in the general population, but it is accurate to call it a real risk amplifier in people with vulnerability, particularly with early, heavy, high-THC use.

  • Respiratory effects. Smoked cannabis delivers many of the same combustion byproducts as tobacco smoke and is linked to chronic bronchitis symptoms with regular use; edibles and vaporizers avoid this pathway.

  • Reproductive and fertility effects. Evidence here is real but more modest than "infertility." Studies link regular use to reduced sperm concentration and motility in men, and to menstrual cycle disruption and lower ovarian reserve markers in some studies of women; cannabis use during pregnancy is linked to lower birth weight and possible long-term developmental effects in children. These are documented associations and legitimate reasons for caution, especially in family planning and pregnancy — but "causes infertility" overstates current evidence.

  • Cancer risk. The data are mixed and less conclusive than for tobacco. Some studies have found an association between long-term heavy cannabis use and testicular germ cell tumors (specifically nonseminoma); a clear, consistent link to lung cancer, as exists for tobacco, has not been established, partly because heavy cannabis smokers usually also smoke tobacco, confounding the data.

  • Escalation and dependence. Roughly 1 in 10 cannabis users overall develop cannabis use disorder, rising to something like 1 in 6 among those who start as teenagers, and higher still among daily users. Whether cannabis is a literal "gateway" to harder drugs is contested among researchers — the more defensible framing is that heavy early cannabis use correlates with, rather than straightforwardly causes, later use of other substances.

  • Potency creep. A frequently overlooked modern factor: legal-market cannabis is often far more concentrated in THC than what was available decades ago, and concentrate products (dabs, vape cartridges) can run 60-90% THC — meaning today's "casual" use is often chemically closer to what used to be considered heavy use.

Before lighting up your next joint, think for a moment why it, all of the sudden, became legal and available to you, and whose pockets you are filling.
