Frustrated that people continued to consume so much alcohol even after it was banned, federal officials had decided to try a different kind of enforcement. They ordered the poisoning of industrial alcohols manufactured in the United States, products regularly stolen by bootleggers and resold as drinkable spirits. The idea was to scare people into giving up illicit drinking. Instead, by the time Prohibition ended in 1933, the federal poisoning program, by some estimates, had killed at least 10,000 people. [...]
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.
The results were immediate, starting with that horrific holiday body count in the closing days of 1926. Public health officials responded with shock. “The government knows it is not stopping drinking by putting poison in alcohol,” New York City medical examiner Charles Norris said at a hastily organized press conference. “[Y]et it continues its poisoning processes, heedless of the fact that people determined to drink are daily absorbing that poison. Knowing this to be true, the United States government must be charged with the moral responsibility for the deaths that poisoned liquor causes, although it cannot be held legally responsible.”
His department issued warnings to citizens, detailing the dangers in whiskey circulating in the city: “[P]ractically all the liquor that is sold in New York today is toxic,” read one 1928 alert. He publicized every death by alcohol poisoning. He assigned his toxicologist, Alexander Gettler, to analyze confiscated whiskey for poisons—that long list of toxic materials I cited came in part from studies done by the New York City medical examiner’s office.
Norris also condemned the federal program for its disproportionate effect on the country’s poorest residents. Wealthy people, he pointed out, could afford the best whiskey available. 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.
