"Lean" aka "Purple Drank"
(it's also called "Texas Tea" or "Sizzurp") is NOT made with tea nor are skittles used because skittles won't dissolve.
It is usually made with Mountain Dew or Sprite (it must be a carbonated beverage) and jolly ranchers (candies that dissolve completely).
They prefer to use purple jolly ranchers, which is how it got its name. DJ Screw was known to mix cough syrup with mountain dew and then drop in a "purple drop" (purple jolly rancher" and often rapped about the "syrup"...
*** "Lean" is NOT made with Tea (or any Arizona product). Skittles are not used in the mixture either. ***
EDIT - this post is in response to people saying Trayvon Martin was buying tea and skittles to make "lean".
