In letters to four companies, the Food and Drug Administration says it has
concluded that adding caffeine to alcohol is unsafe. Four Loko and Joose are
among the companies that received the letters. If the companies do not take
action within 15 days, the F-D-A could begin seizing the products. Federal
officials were facing increasing pressure to take action in the wake of
high-profile incidents, especially involving college students. Experts say the
drinks, sometimes called a blackout in a can, contain high levels of alcohol and
caffeine, making it difficult for people to realize how intoxicated they are.
