I have a very close friend that is addicted to Oxy. At her peak she was taking 8 - 12 80mg pills a day. In the last 14 months she has detoxed 4 times. On the last attempt I took her into my home and she lived here for 6 months. She left here clean a month ago. I have kept in touch with her and see her usually at least once a day. I was a big part of her detox along with her family and we have formed a sort of bond. Since she has moved she has got herself a good job and seems to be doing well but, I am starting to see behaviour changes similar to those I saw when she was using the pills. She is becoming aloof, and is irritated when you question her absence. She seems to be pushing myself and her family away and we are concerned that she may be using agian or having a tough time dealing with the addiction on her own. She does continue to visit but not near as often and she never stays very long. A few hours at most. Are there physical tell signs that we can watch for that would indicate if she is using again? Or are there drug tests available to us that would reveal oxy use?
