Warbirds, it is very possible your friend OD'd from "only" one 80mg oxycontin. That dosage is usually reserved for terminally ill patients who have developed a strong tolerance to opiates. There is a time release coating that junkies will scrape off in order to feel a kick from the drug. Very, very few people can handle 80mg of oxycodone unless they have been using/abusing opiates for quite a while. I've seen kids suffer fatal overdoses from just one of these damn things on three occasions. Please do everyone in the scene a favor and just avoid this shit.
