Anyone have experience with Oxycontin addiction?

I'm pretty sure a friend of mine is using and possibly addicted to Oxycontin. I've asked him about it several times, he has admitted to using it in the past and says he now has stopped. I don't believe him but he says he's not when I ask him about it, and kind of gets mad.

I don't really know how else I can handle it if he won't admit that he is still using. Plus, there is a side of me that thinks maybe he's not and Im being over sensitive...

Any advice??
Thanks :)

Oxycontin is know as the hillbilly heroin --it is very addictive and hard to get off of cold turkey.  I had a friend who was hospitallized and sedated for 3 days while she withdrew.  Her ex husband was still taking them - some drs will write a script without second thoughts. 

Is this friend a "boyfriend" or just a friend friend?  I mean if you are in a serious relationship and suspect drug abuse you probably may want to be nosey and snoop around for bottles or other clues that he's lying - but if hes just a friend I guess you'd have to take his word for it and that will be all - except maybe be sure you do all the driving if you go places together.

Its probably none of our business really if he is using or not even if you were married - but I still think you do have a need to know - maybe tell him you are only concerned for his welfare and want him to be honest with you.  If you feel he is telling the truth and has quit then tell him how great that is.

Usually oxy is given for chronic pain sufferers - so maybe ask what he did to fix the pain - he may now be addicted to hydrocodone or like "House" Vicodan.

Thanks. Def NOT a boyfriend. He is a good friend of mine and my boyfriend and some other mutual friends. I've known him since high school. Thanks for the concern though. It's one thing to question a friend, if it was a S/O there would be no more questions, I would be out of there!!

Its just frustrating trying to level with him rationally, and having him lie to my face. His mother and sister totally enable him too. I mean, his sister just won't speak to him, but his mother must just ignore it or something..He lives in her house in a third floor apartment... I don't get it..I guess there is nothing I really CAN do if he won't even admit he is using...

if he's addicted, the fact that you noticed and said something alone might help. 

all you can do is keep calling him on it.  just look him straight in the eye and tell him you love him, but you don't believe him.  and set firm boundaries, because you can't save him.
