I came across this article about cocaine in Coca Cola and just felt like sharing.

The Rise and Fall of Cocaine Cola

It has been estimated that John Pemberton's original "Coke", as it was nicknamed, contained almost 9 milligrams of cocaine per glass. But caffeine increases the effect of cocaine and most customers usually drank more than one glass of Coke; sometimes several throughout the day. Three Cokes would provide roughly 30 milligrams of cocaine, which compares with the 20 to 30 milligrams normally "snorted" in a day by a contemporary cocaine user. So it shouldn't be a surprise that Atlanta's soda fountains soon became almost as popular as its saloons.
