                                In 2010, the U.S. Food and Drug Administration (FDA) declared added caffeine an "unsafe food additive" in pre-mixed alcoholic beverages, forcing brands like Four Loko to reformulate. This regulatory action is the primary reason why caffeine is not allowed in alcohol, stemming from documented public health and safety concerns.
