America’s Food and Drug Administration has informed nearly 30 manufacturers of caffeinated alcoholic beverages that it intends to look into the safety and legality of their products.

“The increasing popularity of consumption of caffeinated alcoholic beverages by college students and reports of potential health and safety issues necessitates that we look seriously at the scientific evidence as soon as possible,” said Dr. Joshua Sharfstein, principal deputy commissioner of food and drugs.

Of the combined use of caffeine and alcohol among U.S. college students in the few studies on this topic, the prevalence was as high as 26 per cent.

Under the Federal Food, Drug, and Cosmetic Act, a substance added intentionally to food (such as caffeine in alcoholic beverages) is deemed “unsafe” and is unlawful unless its particular use has been approved by FDA regulation, the substance is subject to a prior sanction, or the substance is Generally Recognized As Safe (GRAS). FDA has not approved the use of caffeine in alcoholic beverages and thus such beverages can be lawfully marketed only if their use is subject to a prior sanction or is GRAS. For a substance to be GRAS, there must be evidence of its safety at the levels used and a basis to conclude that this evidence is generally known and accepted by qualified experts.

The FDA alerted manufacturers to the fact that the agency is considering whether caffeine can lawfully be added to alcoholic beverages. The FDA noted that it is unaware of the basis upon which manufacturers may have concluded that the use of caffeine in alcoholic beverages is GRAS or prior sanctioned. To date, the FDA has only approved caffeine as an additive for use in soft drinks in concentrations of no greater than 200 parts per million. It has not approved caffeine for use at any level in alcoholic beverages.

The FDA has requested that, within 30 days, the companies produce evidence of their rationale, with supporting data and information, for concluding that the use of caffeine in their product is GRAS or prior sanctioned. FDA’s letter informed each company that if FDA determines that the use of caffeine in the firm’s alcoholic beverages is not GRAS or prior sanctioned, FDA will take appropriate action to ensure that the products are removed from the marketplace.

In the past year, Anheuser-Busch and Miller agreed to discontinue their popular caffeinated alcoholic beverages, Tilt and Bud Extra and Sparks, and agreed to not produce any caffeinated alcoholic beverages in the future.
