Coke
Coca Cola was meant to be a medicine when John Pemberton invented it back in 1885 in Atlanta, Georgia. He marketed it as ‘brain tonic and intellectual beverage’ keeping the recipe a secret, but not hiding the fact that it contained cocaine extracted from the coca leaf and caffeine from kola nuts (here the name Coca Cola). And it was during the prohibition that it became popular as a ‘soft’ drink as people enjoyed the taste of it, without added cocaine of course.
