Helpus, You and your daughter are always in my prayers. I know how hard it is. I believe that my daughter is using heroin, cheaper than oxycontin. I don't know if she is shooting, but it can't be long before she does. I have heard that the average length of time on heroin before one seriously seeks recovery is about 3 years. Your daughter knows what it feels like to live clean, so hopefully she does not go long before wanting recovery again. Hugs, Marle
