Straw Man showing signs of high IQ.
I feel its appropriate to mention the following here.

In addition the autopsy report revealed moderate beginning signs of brain damage, and mild liver damage associated with prolonged use of DXM or in street lingo “Lean “ in an otherwise healthy young man.
WHAT IS “LEAN” ?

According to Urban Dictionary, “Lean” is described as follows:
“… 6. Lean is a mixed drink originating in the Southern Rap culture. It is a mixture of Promethazine and Codeine cough syrup and a soft drink such as Sprite (usually). While other soft drinks may be used, Sprite was the original.
[And now also Arizona Watermelon for Watermelon Drank/Lean]
There are some variations of Lean. For example, Promethazine and Codeine syrup is usually Purple in color. But there are other colors of syrup that work the same way. There is a golden-colored syrup (hydrocodone based) and other colors as well.
Lean slows you down. It makes you feel good. It’s meant to be sipped on, and it taste damn good. One of the best feelings you will ever experience. Euphoria with a hint of sedation. …”
Lean is also the drug mixture that killed Pimp C. nigga pimp c died on an overdose of lean (urban dictionary descriptive)
OK, so now we know Trayvon is seeking a source for a powerful cough syrup, commonly used in the ”drug culture or circle” to make an intoxicating drink called “Lean” – also known as the infamous “purple drank/Purple Lean/Lean/Sizzurp.”
Purple Lean, or Lean, is an intoxicating beverage also known by the names lean, sizzurp, and liquid codeine. It is commonly abused by southern rappers and wannabe suburban teenagers. It is a mixture of Promethazine/Codeine cough syrup and sprite, or other beverage [such as Arizona Watermelon] with a few jolly ranchers and/or skittles thrown in.
