There has been much controversy over the years about if theres coke in coke a cola. Many believe that there is while the official story says there isn’t. However I have found they tend to leave out that there used to be coke in cola but trace amounts. This is not still true to the product we drink today but it was when it was originially manufactured. There were only trace amounts though just to get you to crave the product.
