Lean, also known as Purple Drank or Sizzurp, is a recreational drug that is a mixture of prescription cough syrup containing codeine and/or promethazine, soda, and sometimes hard candy. Codeine is an opioid classified as a Schedule II controlled substance, meaning it has a high potential for abuse and addiction and is only intended for prescribed medical uses such as relieving mild pain or reducing coughing. Promethazine is an antihistamine that can enhance the effects of codeine. Lean is highly addictive and can have serious health effects, including respiratory depression, overdose, and in some cases, death. It is especially dangerous because it is easy to make and can be attractive to young users who may not realize the risks. The effects of Lean can be seen in rappers who have glorified the usage of the drink in their music, and it has been associated with prominent figures in the music industry. It is important to note that Lean is not safe to drink under any circumstances, and it is illegal to consume it without a prescription.
