"After a 21-year-old with a heart condition died of cardiac arrest following consumption of a Charged Lemonade, the company added a warning to that menu item; the victim’s family has filed a wrongful-death lawsuit alleging the drink was not advertised as an energy drink. The Charged Lemonade is promoted as containing roughly 390 milligrams of caffeine, and the chain’s warning claims it contains the same amount as its dark roast—but that comparison is misleading: a large Charged Lemonade contains about 100 milligrams more than the chain’s large dark roast (the dark roast is listed at 268 mg), putting a single serving near commonly cited daily limits. The incident has highlighted concerns about deceptive advertising and the broader trend of adding high doses of caffeine to mainstream foodservice beverages." - Jaya Saxena
