According to this analysis, the 0.13 micrograms of cocaine per can of the drink does not pose a serious health threat — you'd have to drink 12,000 L of Red Bull Cola for negative effects to be felt — but it was enough to cause concern.
Red Bull has always been upfront about the recipe for its new cola. Its website boasts colorful pictures of coca, cardamom and Kola nuts, along with other key "natural" ingredients. The company insists, however, that coca leaves are used as a flavoring agent only after removing the illegal cocaine alkaloid. De-cocainized extract of coca leaf is used worldwide in foods as a natural flavoring.
