When Coca-Cola was first brewed up in the late 1800s, it actually included cocaine as one of its ingredients. Back then, adding cocaine to drinks was legal and was thought to give you a bit of a buzz. However, as time went on, concerns started swirling about its addictive nature and health risks. This prompted Coca-Cola to kick cocaine out of its recipe in 1904, adjusting to evolving attitudes and tighter rules around drug use.

They made it mandatory to have separate places for people of different races in schools, buses, and other public spots.

But it turned into a big mess, violating a lot of people’s rights, and eventually, everyone realized it was a bad idea.

But thanks to those who fought against it and changed the laws—slavery eventually became illegal almost everywhere.

Bloodletting was all about doctors intentionally bleeding patients to balance their bodily fluids and cure illnesses. It was rooted in old-school medical theories and stuck around as a legal and widespread treatment.

That’s when doctors ditched it in favor of treatments that actually worked.
