What is another term for drugs mixed with codeine in syrup form often referred to as 'lean'?

The term 'lean' specifically refers to a recreational drink that is made by mixing prescription-strength cough syrup that contains codeine and promethazine with a soda or other sugary beverage. This mixture is famous in certain music and subcultures, making "Promethazine w/ Codeine" the correct answer, as it directly identifies the specific medication involved in creating this drink. This syrup acts both as a cough suppressant due to its codeine content and has sedative properties because of the promethazine, which contributes to the euphoric effects associated with 'lean.'

Other options represent various substances but do not accurately describe the mixture known as 'lean.' For instance, while cough syrup is a general term for any syrup used to treat cough, it does not specify the combination of promethazine and codeine that defines 'lean.' Mescaline is a hallucinogenic substance unrelated to codeine, and methamphetamine is a powerful and illegal stimulant that does not share any characteristics with 'lean.' Understanding the distinction between these substances is key to recognizing the specific combination that forms 'lean' and its associations in culture.
