Pemberton invented coca-cola in 1886. Coca-cola is a sweet, carbonated drink. And my favorite soda! Back to the history now! It contains caffeine from kola nuts. Another reason why it’s so rare for me to have one. It has caffeine in it! Back to the history…again. Coca-cola originally contained cocaine. Then cocaine was removed in 1903.
