… Although mostly forgotten today, the “chemist’s war of Prohibition” remains one of the strangest and most deadly decisions in American law-enforcement history. As one of its most outspoken opponents, Charles Norris, the chief medical examiner of New York City during the 1920s, liked to say, it was “our national experiment in extermination.” Poisonous alcohol still kills—16 people died just this month after drinking lethal booze in Indonesia, where bootleggers make their own brews to avoid steep taxes—but that’s due to unscrupulous businessmen rather than government order.
… During Prohibition, however, an official sense of higher purpose kept the poisoning program in place. As the Chicago Tribune editorialized in 1927: “Normally, no American government would engage in such business. … It is only in the curious fanaticism of Prohibition that any means, however barbarous, are considered justified.” Others, however, accused lawmakers opposed to the poisoning plan of being in cahoots with criminals and argued that bootleggers and their law-breaking alcoholic customers deserved no sympathy. “Must Uncle Sam guarantee safety first for souses?” asked Nebraska’s Omaha Bee. …
The saga began with ratification of the 18th Amendment, which banned the manufacture, sale, or transportation of alcoholic beverages in the United States.* High-minded crusaders and anti-alcohol organizations had helped push the amendment through in 1919, playing on fears of moral decay in a country just emerging from war. The Volstead Act, spelling out the rules for enforcement, passed shortly later, and Prohibition itself went into effect on Jan. 1, 1920.
But people continued to drink—and in large quantities. Alcoholism rates soared during the 1920s; insurance companies charted the increase at more than 300 more percent. Speakeasies promptly opened for business. By the decade’s end, some 30,000 existed in New York City alone. Street gangs grew into bootlegging empires built on smuggling, stealing, and manufacturing illegal alcohol. The country’s defiant response to the new laws shocked those who sincerely (and naively) believed that the amendment would usher in a new era of upright behavior.
Rigorous enforcement had managed to slow the smuggling of alcohol from Canada and other countries. But crime syndicates responded by stealing massive quantities of industrial alcohol—used in paints and solvents, fuels and medical supplies—and redistilling it to make it potable.
Well, sort of. Industrial alcohol is basically grain alcohol with some unpleasant chemicals mixed in to render it undrinkable. The U.S. government started requiring this “denaturing” process in 1906 for manufacturers who wanted to avoid the taxes levied on potable spirits. The U.S. Treasury Department, charged with overseeing alcohol enforcement, estimated that by the mid-1920s, some 60 million gallons of industrial alcohol were stolen annually to supply the country’s drinkers. In response, in 1926, President Calvin Coolidge’s government decided to turn to chemistry as an enforcement tool. Some 70 denaturing formulas existed by the 1920s. Most simply added poisonous methyl alcohol into the mix. Others used bitter-tasting compounds that were less lethal, designed to make the alcohol taste so awful that it became undrinkable.
To sell the stolen industrial alcohol, the liquor syndicates employed chemists to “renature” the products, returning them to a drinkable state. The bootleggers paid their chemists a lot more than the government did, and they excelled at their job. Stolen and redistilled alcohol became the primary source of liquor in the country. So federal officials ordered manufacturers to make their products far more deadly.
By mid-1927, the new denaturing formulas included some notable poisons—kerosene and brucine (a plant alkaloid closely related to strychnine), gasoline, benzene, cadmium, iodine, zinc, mercury salts, nicotine, ether, formaldehyde, chloroform, camphor, carbolic acid, quinine, and acetone. The Treasury Department also demanded more methyl alcohol be added—up to 10 percent of total product. It was the last that proved most deadly. …
Most of those sickened and dying were those “who cannot afford expensive protection and deal in low grade stuff.”
And the numbers were not trivial. In 1926, in New York City, 1,200 were sickened by poisonous alcohol; 400 died. The following year, deaths climbed to 700. These numbers were repeated in cities around the country as public-health officials nationwide joined in the angry clamor. Furious anti-Prohibition legislators pushed for a halt in the use of lethal chemistry. “Only one possessing the instincts of a wild beast would desire to kill or make blind the man who takes a drink of liquor, even if he purchased it from one violating the Prohibition statutes,” proclaimed Sen. James Reed of Missouri.
Officially, the special denaturing program ended only once the 18th Amendment was repealed in December 1933. … And when Prohibition ended and good grain whiskey reappeared, it was almost as if the craziness of Prohibition—and the poisonous measures taken to enforce it—had never quite happened.
