is the medication kadian stronger than oxycontin? My do dr. prescribed me oxycontin and my insurance wouldn't cover it so gave me a different prescription of kadian, which I googled and states that its morphine. Im highly concerned about taking that, isn't that given to cancer patients? Also, I take a lot of other medications for anxiety depression and fibromyalgia and also highly concerned about the interactions based off of what I just read when I googled it.
