Welcome to SR. My daughter is my addict. She is 21 and has done all the opiates. Currently I am not really sure what she is using as I have not seen her since March. If your daughter has relapsed, it will not be long before you know it for sure. If she is nodding, that is usually associated with opiates or another downer. My daughter does oxycontin and that could be what the white is. But really it doesn't matter what drug she is using if she is. One thing I know for sure is that addicts will deny their using even when faced with the evidence. My daughter did not live with us when she started to use so I have never been faced with the problem of what to do with that. I do know that she will never live with us again. Hugs, Marle
