"Blueberry


(n.) street slang used to describe any form of the narcotic Percocet, including roxicodone, oxycodone, and any other generic form of the dr-ug.


The name derived from the blue colour of the pill and its apparent small size, as well as the need to obtain the dr-ug over the phone while being in a public area so as to not draw suspicion from people around them.


Also see 'blue skies'.


Roxicodone is used for:


Treating moderate to severe pain. It may be used before surgery to sedate the patient and reduce fear. It may also be used for other conditions as determined by your doctor.


Roxicodone is a narcotic pain reliever. It works by dulling the pain perception center in the brain. It may also affect other body systems (eg, respiratory and circulatory systems) at higher doses.
