Lean, also known as purple drank, purple lean or lean drink, is a drug concoction typically made from three items commonly found in the home — prescription cough syrup, soft drinks and hard candy. Because prescription cough syrup frequently contains codeine, an opiate, the mixture offers the same high and poses the same dangers as other narcotic drugs would. Promethazine, an antihistamine and sedative also frequently found in prescription cough syrup, compounds the risks.
Also, the carbonation in the soft drink aids the body’s absorption of the drug, increasing the speed and intensity of the high. The soft drink component of the mixture, as well as the candy, also make the concoction extremely palatable, so that it is easy to take a lot of the drug and difficult to know how much active drug is being consumed each time. The legal nature of the drug’s ingredients makes abuse challenging to track and also make professional help necessary in overcoming your dependency.
