RP just means Rhodes Pharmaceuticals. It is a generic brand and formulation of Oxycodone 30MG. These are probably the most sought after opioid in my area as it is IR Oxy and quite a decent dose at that. There is a high potential for abuse with these pills. It is a high enough dose to make it worth it for some to insufflate the powder, but orally it works best so it is a favorite of many. You said the first time in decades, so I am assuming your friend just got a new brand of her meds. While these aren't blue like the majority of OC30, I can assure you they are the same exact thing.
