We begin north of the Rio Grande, the source of the insatiable demand for, and interdiction of, narcotics from Mexico. In the United States, the use and sale of various psychoactive drugs—notably opium, marijuana, and cocaine—had been perfectly legal in the nineteenth century and into the early years of the twentieth. Indeed, drug peddling had become big business. Pharmaceutical and patent medicine companies added opium derivatives (morphine, laudanum, heroin) to home remedies for assorted ailments, opiates being one of the few effective forms of pain control available. The typical opium user was a middle-aged, middle-class, white woman. Cocaine, too, was added to medicinal and recreational commodities ranging from cigarettes to soft drinks. Coca-Cola was tinctured with coca leaves until 1903.
Slowly during the 1890s, then with mounting determination during the 1900s and 1910s, a variety of players promoted the criminalization of narcotics, a movement that paralleled the simultaneous push to outlaw alcoholic beverages. These drug prohibitionists included: doctors newly aware of the additives’ addictive capabilities (and who now had, in aspirin, an effective substitute); muckrakers who denounced corporations for using drugs to hook customers on their products; and anxious racists of various stripes, such as southern whites who claimed cocaine drove Negroes to rape white women, and anti-Chinese activists who charged them with using opium to seduce white women. As David Musto notes, it was not fear of drugs per se that drove the prohibitionists, so much as fear of the social groups who used them.
First, some state governments were won over to prohibition. Then, in 1906, the Pure Food and Drug Act required manufacturers to list the ingredients in their narcotics-laden products, alarming many of the housewives who unwittingly had been spooning opiates to their children. In 1909 the Smoking Opium Exclusion Act successfully barred importation of the form in which most Chinese ingested the drug—putting opium dens out of business—while exempting medicinal versions used by white Americans. The 1909 initiative was prompted, also, by American businessmen’s desire to break Europe’s (and especially England’s) grip on the lucrative China market, as it was thought (correctly) that banning opium would play well with the Chinese authorities who were then trying to stamp out the widespread use of a drug that, since the 1840s, had been pushed on them at gunpoint by the British.
These proscriptions had several unanticipated consequences. Scarcity drove up the price, which attracted criminal traffickers. It also induced former opium smokers to switch to more potent and more dangerous derivatives, like morphine and heroin. The prohibitionists responded by tightening restrictions. They also pushed for international criminalization—winning in the Hague Convention of 1912 commitments from several nations to restrict opium and cocaine. In the U.S. they won passage of the Harrison Act in 1914, which prohibited all non-medicinal use of opiates and cocaine, though not cannabis, which was (correctly) adjudged to be relatively harmless.
The United States had declared war on drugs.
The subsequent shortages, and skyrocketing prices, drew a new generation of gangsters to the trade (Lucky Luciano’s first arrest, in 1916, was for peddling opium). With passage of the Eighteenth Amendment and the Volstead Act in 1919, the production, distribution, and sale of alcoholic beverages were banned, triggering the shift from licit to illicit purveyors that spawned modern organized crime in the U.S. Gangster entrepreneurialism was further accelerated by criminalization of the manufacture, importation, and possession of heroin in 1924—which promptly galvanized yet another underground market. Arnold Rothstein, New York’s master criminal, alerted by his protégé Luciano about the profit potentials—a kilo of heroin could be bought for $2,000, then cut and resold for $300,000—shifted out of rum-running in the mid-1920s, and turned instead to importing opium and heroin from Europe. Purchasing a well-reputed mercantile firm as cover for his wholesaling operations, Rothstein began distributing to a national market, dispatching the goods by rail.
The booming U.S. demand for narcotics also attracted attention in Mexico. While the climate in the United States was not suitable for poppy horticulture, Mexico was situated in a latitude zone that provided the perfect temperature for cactuses (at lower altitude) and poppies (at higher elevations). Conditions for opium cultivation were particularly ideal in the Golden Triangle, a region in the western Sierra Madre mountains (of Treasure fame) where the states of Sinaloa, Durango, and Chihuahua come together. (See map, page vi.) It was there that poppy production blossomed—introduced in the 1880s by Chinese migrants who had been forced out of the U.S. or had arrived by sea to Sinaloa, a state that runs for four hundred miles along Mexico’s Pacific coast. Most worked on the railroads and in the mines, but some rural Chinese families entered into production of opium and marijuana. Their numbers increased after the United States banned further immigration, with passage of the baldly titled Chinese Exclusion Act of 1882 and its subsequent iterations in 1892 and 1902. In the first decade of the twentieth century the number of Chinese living in Mexico quintupled (from 2,660 to 13,203), and more opted to engage in cultivation. During and after the Revolution, in the 1910s and 1920s, they were joined by some of the many Mexican farmers who had been impoverished by the war’s devastation.
Over these decades Chinese immigrants and their descendants fashioned a rough-hewn drug trafficking network. After harvesting the poppies and extracting the goma (gum, latex paste) from the poppy seedpods, they conveyed raw or cooked opium to Chinese dealers in the U.S. (chiefly Los Angeles) via a series of outposts in towns between Sinaloa and the cities on Mexico’s northwest border, notably Tijuana. More and more Mexican peasants, middle-class townsfolk, and some wealthy merchants jumped into the business. It was easy to enter—there were no significant start-up costs. Nor was there significant danger: there was room for everybody, hence no need to employ violence to stake out market share.
The U.S. border—360 miles to the north—was not only close to Sinaloan traders and producers (called gomeros after the goma) but also notoriously porous. It had been so for a long time, ever since the Mexican War (La Invasión Norteamericana [1846–1848]) had violently redrawn the line of demarcation, shifting vast holdings of gold, coal, iron, and copper, along with great tracts of fertile agricultural land, to the U.S. side of the ledger, including all or parts of California, New Mexico, Arizona, Nevada, Utah, and Colorado. The newly inscribed frontier (enhanced by an additional strip purchased in 1853) became one of the longest borders on the planet, stretching two thousand miles. It ran from Tijuana, on the Pacific coast, through deserts and arid hills to Ciudad Juárez at roughly the halfway mark, and from there it jagged southeast, running along the Río Bravo (as Mexicans call the Rio Grande) down to the Gulf of Mexico.
Almost immediately the border was transgressed more or less at will. In the 1850s slaves smuggled themselves across to freedom: Mexico, having abolished slavery, awarded citizenship to runaways who headed not toward the North Star (Canada) but the Southern Cross. In the 1860s Confederates smuggled cotton to Mexico for transshipment to Europe, and gun runners sent munitions to help Benito Juárez fight the French. Cattle rustlers ambled over from both north and south, stealing herds and driving them across the border for rebranding and sale. A brisk commerce in tequila, pulque, mescal, and rum also sprang up, flowing north to the U.S. from Mexican distilleries, avoiding tax collectors and, later, prohibition agents.
There was also an easy flow of people back and forth. Border crossing was a breeze because there were no official restrictions or quotas on Mexican movement north; even after the U.S. imposed stringent quota laws in the 1920s, Latin Americans remained exempt. The U.S. Border Patrol, created in 1924, focused on Europeans or Asians
