John Pemberton was born in George in 1831. He fought in the Civil War. He became addicted to morphine after he got saber slashed. He relished his addiction and experimented with coca wines. It helped with the morphine addiction. Unfortunately a law passed for no one to have any alcoholic beverage. So Pemberton had to think of something else for his morphine addiction. 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. While we know the general ingredients of coca-cola the whole recipe is a secret.
