I'm not sure but I did hear that coca cola used to produce the drink with trace amount of coca (cocaine) to induce addiction. Not positive tho

It used to be made with cocaine.

Per Wikipedia The first Coca-Cola recipe was invented in Columbus, Georgia at a drugstore by John Stith Pemberton, originally as a cocawine called Pemberton's French Wine Coca in 1885.[2][3] He may have been inspired by the formidable success of European Angelo Mariani's cocawine, Vin Mariani. In 1886, when Atlanta and Fulton County passed prohibition legislation, Pemberton responded by developing Coca-Cola, essentially a non-alcoholic version of French Wine Cola. The original recipe was made witout carbonated water, but was added later when Pemberton was mixing the drink for friends without the carbonated water and accidentally added it to a glass. His friends loved it more and he decided to continue making his drink with the carbonated water instead.[4] The first sales were at Jacob's Pharmacy in Atlanta, Georgia, on May 8, 1886.[5] It was initially sold as a patent medicine for five cents[6] a glass at soda fountains, which were popular in the United States at the time due to the belief that carbonated water was good for the health.[7] Pemberton claimed Coca-Cola cured many diseases, including morphine addiction, dyspepsia, neurasthenia, headache, and impotence. Pemberton ran the first advertisement for the beverage on May 29 of the same year in the Atlanta Journal.[8] For the first eight months only nine drinks were sold each day.[citation needed] By 1888, three versions of Coca-Cola — sold by three separate businesses — were on the market. Asa Griggs Candler acquired a stake in Pemberton's company in 1887 and incorporated it as the Coca Cola Company in 1888.[9] The same year, while suffering from an ongoing addiction to morphine, Pemberton sold the rights a second time to four more businessmen: J.C. Mayfield, A.O. Murphey, C.O. Mullahy and E.H. Bloodworth. Meanwhile, Pemberton's alcoholic son Charley Pemberton began selling his own version of the product.[10] In an attempt to clarify the situation, John Pemberton declared that the name Coca-Cola belonged to Charley, but the other two manufacturers could continue to use the formula. So, in the summer of 1888, Candler sold his beverage under the names Yum Yum and Koke. After both failed to catch on, Candler set out to establish a legal claim to Coca-Cola in late 1888, in order to force his two competitors out of the business. Candler purchased exclusive rights to the formula from John Pemberton, Margaret Dozier and Woolfolk Walker. However, in 1914, Dozier came forward to claim her signature on the bill of sale had been forged, and subsequent analysis has indicated John Pemberton's signature was most likely a forgery as well.
