A caffeine-free drink is a beverage that does not contain any caffeine. Common examples of such drinks include SPRITE, which is a lemon-lime flavored soft drink, herb tea, which is a type of tea made from herbs and spices, and mint tea, which is a type of tea made from the leaves of the mint plant. All of these drinks are free of caffeine and can be enjoyed without the risk of consuming too much of the stimulant.
