For the record, Mass RC, I do have a great deal of experience with both mental and drug addicted patients. While I am no longer actively involved with direct patient care, I do hold an RN degree. In fact, I did it for ten years, before my career change. My areas of specialty included mental health, drug rehabilitation and nursing education. Believe it or not I worked at a mental health hospital in NY, where the worst cases were found. I've been punched, bitten, spit at, had my clother ripped off me, etc. I know all about enraged patients. I can write a book on it.
