Rodríguez proposed an amendment to the Constitution that would give Congress the power to prohibit the “selling of substances which poison the individual and degenerate the [Mexican] race.” He named alcohol, opium, morphine, ether, cocaine, and marijuana (the latter being “one of the most pernicious manias of our people”). He also urged writing into the revolutionary charter a provision for a federal department of public health, whose recommendations on issues of civic hygiene would have the force of law. This was done; the new Constitution was approved in 1917, and in 1918 the agency was established, with Rodríguez as its head. He now pushed for draconian measures and, during the last days of the Carranza regime, had the department promulgate “Decrees on the Cultivation and Commerce of Products that Degenerate the Race.” These banned the growing of opium and the extraction of its narcotic latex without special permission; banned completely the production and sale of marijuana, nationwide; required drug wholesalers to obtain special permission to import opiates or cocaine; and mandated that such importers sell those drugs only to licensed medical distributors, or to doctors who had received specific permission to receive and prescribe them.
Mexico had declared war on drugs.
Implementation was forestalled by renewed revolutionary chaos, as Generals Álvaro Obregón and Plutarco Elías Calles, among others, took up arms against the Carranza regime. In May 1920, with rebel forces closing in, Carranza left the capital for Veracruz but never made it, having been murdered (or committed suicide) on the way. Obregón was now elected to succeed him, and Mexico entered a period of (again relative) tranquility. In 1923 Obregón peacefully passed the presidential torch to his comrade-in-arms Calles, who during his term in office (1924–1928) resuscitated the delayed assault on illicit substances.
Calles was determined to realize the transformative visions embodied in the Constitution but not yet wholly enacted. In preparation, he had undertaken a 1923 tour of Europe to study contemporary socialist practice. He consulted particularly with German Social Democrats, and also corresponded with Turkey’s Mustafa Kemal Atatürk, who was just then embarking on an analogous program of political, economic, and cultural reforms to transform the former Ottoman Empire into a modern and secular nation-state. In particular, Calles set about ruthlessly enforcing constitutional curtailments of Catholic prerogatives — breaking the Church’s grip on the educational system, and prohibiting religious rituals outside of churches, which themselves became the property of the nation. This sparked a furious resistance by Catholic peasants that spiraled into the ferocious Cristero War (1926–1929) in which seventy thousand to ninety thousand died.
For all his anti-clericalism, Calles sought the moral betterment of the Mexican people. As had his Revolutionary predecessors, he saw combating drug use as one way to accomplish this. Alcoholism was his original bête noire. As governor of Sonora he had prohibited by decree the importation, manufacture, or sale of intoxicating beverages. Violators were to be punished with five years in prison, though he underscored his determination by summarily executing one poor drunkard. As president, he lit into narcotics.
In February 1925 the New York Times reported, in a story headlined “Calles Orders Drug War,” that the new president had announced he would “punish all drug handlers and users of drugs in Mexico.” He had, moreover, fired policemen who “were recently implicated in the drug traffic through protecting importers.” Follow-up stories hailed Calles’ announcement that he would “clean out” traffickers from border towns, shut down retail outlets in Mexico City, and go after transshipments from Asia and Europe. (Opium and heroin arrived to Acapulco and other west coast ports on Japanese vessels, sometimes hidden inside fish, or were transported to east coast ports like Tampico and Veracruz from Germany, Belgium, and France.) The government also assaulted opium growers — destroying several hundred acres of Chinese-cultivated poppies in the states of Nayarit and Durango — and went after pot producers too.
“Mexico Bans Marihuana,” declared a December 1925 New York Times story recounting industrious efforts by public health department inspectors to arrest farmers and incinerate their crops. Marijuana leaves, the paper explained, retailing an emerging north-of-the-Río-Bravo version of Mexico’s conventional wisdom, “produce murderous delirium” that often drives addicts insane, adding: “Scientists say its effects are perhaps more terrible than those of any intoxicant or drug.” In 1931, Luis Astorga notes, drug consumption and trafficking were defined as federal crimes.
Calles also set in motion momentous changes in the nation’s political structure that would greatly impact once and future drug wars, albeit in contradictory ways. In 1928 he proposed ending caudillismo—the seemingly endless battle for preeminence between rival generals — by bringing all factions together inside one capacious political entity, the PNR (Partido Nacional Revolucionario or National Revolutionary Party). Established the following year, the PNR solved the vexing problem of presidential succession by allowing the outgoing president, in consultation with other party chieftains, to choose the incoming one. The procedure became known as el dedazo—“the tap of the finger”—with the announcement serving as a sort of secular Annunciation. The term of office was changed from four to six years (a period that became known as the sexenio). Reelection was strictly prohibited, thus barring any replay of Porfirian-style “elective” dictatorship.
This was no small achievement, given the fate of most other Latin American nations: there would be no dictators-for-life, no Somozas or Trujillos in Mexico’s future. Calles, to be sure, did not completely follow his own script. After his term expired, he managed to select and de facto dominate his three de jure successors, with each serving only two years; hence he became known as the behind-the-scenes Jefe Máximo (“Maximum Leader”). In 1934 he fingered Lázaro Cárdenas, and even chose his cabinet for him. But in 1936, Cárdenas finally put Calles’ principles into practice by having him pulled from his home at midnight and bundled off to exile in San Diego.
Cárdenas, a Depression Era president whose 1934–1940 term overlapped two of FDR’s, extended and deepened the Revolutionary legacy: nationalizing oil and railroads; redistributing forty-five million acres of hacienda land to peasants; reviving the system of ejidos (communal land, parcels of which were possessed and worked by individuals, but not owned or sellable by them, forestalling re-accumulation of giant encomienda tracts); expanding social services and secular schools; and supporting strikes that lifted workers’ wages. He also sought to organize core sectors of society into consolidated entities — like the CTM (Confederation of Mexican Workers), a vast collection of unions — with equivalent corporatist bodies for peasants, businessmen, professionals, the military, and others. These were then incorporated into the PNR, which in 1938 he renamed the PRM (Partido de la Revolución Mexicana or Party of the Mexican Revolution). The political order had been transformed from an elite to a mass-based system. Within a year, the PRM claimed some 4.3 million members.
