I have a friend who promised me that she has stopped sniffing this drug however I do not believe that she has. She has major mood swings. she has children and a husband that she promised also that she has stopped. What could happen to her if she does not stop and what are signs that we should look for if she still is sniffing oxycontin, I thinks she has had drub abuse problems for many years. Can she just stop sniffing this drug easily without side effects? She keeps promising she will but her husband has valid evidence that she has not. She even has had a straw and the drug in her hand but calls him a liar. Her children are aware of this, Her husband is ready to divorce her but does not want to because of children and finances. She has embarressed the entire family and people she works with also note that something is wrong. I do not think they are aware. She is awful, hatefull. I am afraid for the children eventhough they are older, I am also worried about her husband.
