The Massachusetts Alcoholic Beverages Control Commission has released a regulation relating to the recent uproar over FourLoco. The regulation bans the sale of alcohol adulterated with caffeine.
The FDA has also responded by warning manufacturers that their products contain an unsafe food additive. They have issued a press release and letter to manufacturers. The CDC (Center for Disease Control and Prevention) has issued a fact sheet on the dangers of alcohol and caffeine.
The drink has already been banned in individual states, but the FDA action likely means national prohibition.
