The Centers of Disease control and Prevention has a Warning for those who mix Cola and alcohol because of high level of caffeine and mixing the two is a bad idea as it contains very harmful effects.
Many are aware that cola contains caffeine, in a typical 330ml can, there’s approximately 34 milligrams of caffeine, while diet cola slightly surpasses that with around 46mg. This is notably less than the 63mg typically present in a single shot of espresso. It’s worth noting, however, that it’s more common for individuals to consume multiple vodka and Cokes in one sitting than shots of espresso.
For those who enjoy combining alcohol with caffeine, the Centers for Disease Control and Prevention in the US issues a cautionary message.
