A friend gave me half of a brown opana 30. I'm assuming it's the new formulation of ER. Im not an addict and have only been dabbling in opiates for a bout a month now. I've taken 20-25mg of roxicodone a handful of times and felt wonderful. I haven't taken any opiates at all in about a week. Since I have 15mg of opana, which is half of a 30mg, what would be a good dose if I'm able to handle 20mg of roxicodone? Also what is the best roa with this new formulation?
