I was definitely informed by a chemist that the cola drinks are just as harmful as tea or coffee, and his advice was to leave all such substances alone. [“Use of Cola Drinks and Playing Games of Chance,” Answers to Gospel Questions, vol. 5 (Salt Lake City, Utah: Deseret Book Company, 1966), p. 75.]

The harmful effects of the cola drinks have been mentioned many times. But other drinks are often marketed that contain caffeine. Buyers should know well the products they are purchasing.
