D.L. 

Code for the Devil's Lettuce or marijuana. Primarily used as a code by parents around their children indicating they would enjoy smoking some at a later point when the children are fast asleep.

Barbara had a heck of a day and was jonesing to blaze, so she asked her boyfriend Matt if he would be down with some D.L. later on to help quell her nerves.

Cop pulled me over, took my D.L. and looked at it for like 5 minutes. Thought I was in some deep stuff, but he mentioned I looked like a guy he went to school with.
