See, "defaultused" was one of my subjects in my experiments on 80mg IV oxycodone for a non-tolerant user. And as he mentioned, he did vomit, layed on my couch for a while, but otherwise was fine. Evidently he otherwise enjoyed the high. I prepared and administered the shot, as in the other cases. Again, i dont suggest trying this unless you have antagonists around.
Although all the subjects were fine, i do not suggest IVing 80mg of oxycodone without a tolerance, i dont even suggest taking that dose without a tolerance by any route of administration. If your used to shooting, especially high doses of cocaine (which lessens the effect of oxycodone) 40mg would be a reasonable dose.
