What was Coca-Cola and original ingredient that has since been made illegal?

Coca-Cola originally contained coca leaf extract, which included small amounts of cocaine. This ingredient was part of the original formula created in 1886, but due to changing regulations and growing awareness of the dangers of cocaine, it was removed from the beverage by the early 20th century. Today, Coca-Cola uses a cocaine-free coca leaf extract for flavoring, ensuring compliance with legal standards.
