Caffeinated alcoholic drink
A caffeinated alcoholic drink is a drink that contains both alcohol (also known formally as ethanol) and a significant amount of caffeine. Caffeine, a stimulant, masks some of the depressant effects of alcohol. However, in 2010 and 2011, this type of drink faced criticism for posing health risks to its drinkers. In some places there is a ban on caffeinated alcoholic drinks.
Sometimes, caffeinated alcoholic drinks are made by mixing existing caffeinated drinks (coffee, energy drinks, cola) with alcoholic drinks.
