What is a roxy?

Roxy is a street name (like oxy, which on the street is usually oxycontin, not oxycodone).
It could be roxicodone, roxicet, roxilox, roxiprin (all combos of either aspirin or acetominophen with oxycodone, kinda like percocet, but all of varying strengths, dosages, etc, some MUCH stronger than others, some considered long-acting and therefore time released pills which should always be taken whole, not cut or chewed up). It could also be roxanol (which is a morphine as opposed to oxycodone, and again, all the same warnings - varying strengths, dosages, some time-released and some not, etc).
Depending on exactly what it is, and what strenth, could be pretty seriuos (i.e. dangerous) stuff. Sorry I can't be more specific. If you can't get more info but can see one of the pills, there are various pill identifiers including one on this site that you can use to determine exactly what it is.
