Men in Sierra Leone sorting kola nuts, a bitter tasting caffeine-containing fruit found on the cola trees of West Africa.
Kola nuts have various uses in many different West African societies, ranging from ceremonial offerings to healing practices.
In 1800s, American pharmacist John Pemberton introduced them to the Western world by combining kola nuts with sugar, carbonated water and other ingredients to make the first cola soft drink in the West. Coca-Cola no longer uses kola nuts in its recipe.
