How does lean stay in your system?

Lean, also known as purple drank, typically contains codeine, which is an opiate. When ingested, codeine is metabolized in the liver and can remain in the body for several hours, with its effects lasting around 4 to 6 hours. The drug can be detected in urine for up to several days after use, depending on factors like dosage, frequency of use, and individual metabolism. Regular use may lead to accumulation in the system, increasing the risk of dependence and adverse effects.
