What are codeine and promethazine? Codeine is an opiate painkiller which can induce a pleasurable state in those who consume it. Codeine can be thought of as the “star of the show” it provides the pleasurable effects often sought out by the user. Often paired with codeine, and an important part of traditional “lean” is promethazine. Promethazine is an antihistamine which potentiates the effects of codeine. However, promethazine has its own personality and effects the user as much as the codeine. If you have ever taken an OTC antihistamine like Benadryl then you will be familiar with the effects of promethazine. Similar to other antihistamines, users of promethazine appear sleepy, which is another impact of “lean”.
