You've probably heard I didn't know I was pregnant stories that went something like this: A woman claims she took an at-home pregnancy test that came back negative, but, lo and behold, she really was pregnant -- and the pregnancy progressed without her knowledge.
Carbonation in anything you drink allows it to enter the bloodstream faster. There is no difference with an alcoholic beverage. If you drink alcohol that is either carbonated or mixed with a carbonated beverage, then it will absorb into the bloodstream faster than drinks that are not carbonated. Examples are cocktails such as Jack and Coke, which is whiskey mixed with Coca-Cola.
Absorption of alcohol into a person's body occurs through a process known as diffusion. Alcohol need not be digested by the body. Alcohol undergoes no chemical change in the body; rather, it is gradually absorbed into the blood, while it passes through the body's digestive system. The quantity of alcohol present in the blood can then be measured.
