That Time the US Government Poisoned Alcohol

During the 1920s Prohibition era, the US government poisoned industrial alcohol to deter illegal consumption, leading to thousands of deaths. Bootleggers distilled this alcohol, but methanol, a toxic additive, caused severe health issues, including blindness and death. The government later switched to less harmful additives, and methanol poisonings decreased after Prohibition ended.
