Pemberton Turned to Cocaine as a Substitute for Morphine
Like many other addicts, Pemberton wanted to recover and get clean. He knew his morphine problem was dangerous, so he began experimenting with opium-free medicines. After another doctor claimed that opium habits could be cured with coca (cocaine), Pemberton worked on his own concoction using coca leaves and kola nuts.

As we mentioned, this specific concoction was called Pemberton’s French Wine- coca leaves and red wine. It was during the prohibition when the physician was required to remove the alcoholic component of his formula, which ultimately led to Coca-Cola. What’s interesting is that during this time, coca was thought to help with substance abuse. Of course, we now know that cocaine is a powerful and addictive drug as well.
