How much cough syrup do you put in lean?

Lean, also known as purple drank, typically combines prescription cough syrup containing codeine and promethazine with a soft drink, often flavored with candy. The amount of cough syrup varies based on personal preference and strength of the syrup, but it is crucial to emphasize that misuse of cough syrup can be dangerous and illegal. Consuming lean poses serious health risks, including addiction and overdose. Always prioritize safety and consult a healthcare professional if needed.
