During prohibition alcohol was illegal to buy and consume, but some industrial alcohol had to be made to be used in compounds like paint thinner and embalming fluid. To keep people from drinking industrial alcohol, the government poisoned some batches with mercury, gasoline, and other dangerous and deadly chemicals. The resulting “denatured” alcohol led to the deaths of US citizens. Exactly how many people were poisoned to death by their government is unknown, but general estimates are around 10,000, although it may have been much higher. The program ended when prohibition was repealed in 1933, with thousands of dead and sick Americans left in its wake.
