What is lean made of?

Lean is a drink, typically homemade, consisting of a soft drink (usually Sprite or Mountain Dew), codeine-based prescription cough syrup, and sometimes hard candy.

The active ingredient that produces the intoxicating effects is often <a href="https://www.wikiwhat.page/kavramlar/codeine">codeine</a>, an opioid. Some variants may use promethazine with codeine syrup, where promethazine acts as an antihistamine to increase the sedative effects. Due to the dangers of opioid abuse, it's crucial to understand the risks associated with lean consumption.
