to the pro-Martin camp insisting he was just your average teenage kid caught with stolen wedding bands and watches in a backpack, pictures of him holding a .40 caliber gun, pictures of marijuana potted plants, gold capped teeth, tattoos, fight clubs, school suspensions, getting thrown out of his house by his mother. Yeah REAL average self-proclaimed 
GANGSTA teenager just going to the grocery store to buy Arizona Watermelon Fruit Juice Cocktail and Skittles, the common ingredients to making "Lean" / "Purple Drank" which Martin had been using since at least June 2011. On June 27th, 2011, Trayvon asks a friend online, "unow a connect for codien?" He tells the friend that "robitussin nd soda" could make "some fire ### lean." He says, "I had it before" and that he wants "to make some more." On the night of February 26, if Brandy had some Robitussin at home, Trayvon had just bought the mixings for one "fire ### lean" cocktail. That would explain why neither the Skittles nor the watermelon juice was opened on his walk back from the store. 
Some are speculating he went to the 7-11 to buy more supplies, meaning he was already on "lean" which would explain why he looked lost/disoriented in the 7-11. If OTC cough syrup was used it would also explain why it was not reported unless a full drug screen was performed. At high doses, dextromethorphan (common ingredient in OTC cough syrups) is classified as a dissociative general anesthetic and hallucinogen, similar to the controlled substances ketamine and phencyclidine (PCP). Also like those drugs, dextromethorphan is an NMDA receptor antagonist.
