                                While the illicit street drug known as 'lean' or 'purple drank' contains potent depressants like codeine and promethazine, it does not typically contain any caffeine. However, various commercial fitness supplements and protein shakes are also named 'Lean' and do contain significant amounts of caffeine. Understanding the context is crucial to know if there is caffeine in lean.
