This may be different in Oregon, but in Iowa I was told that any medications provided to me by my psychiatrist, could also be prescribed by my general practitioner who was a DO (and the person who told me this).       He had the same book of recommended drugs, could interview me, and prescribe.     I'm can tell you that most DO/MD do not have a working understanding of chemical compounds and the details of risk involved with the drugs they prescribe.  Doctors of all levels do not look at test data.  Most use prescriptions are guided by their drug reps.


If you are concerned about the abuse of prescription medication,  you might look to the easy to get along with Doc who will prescribe for what you tell him ails you.   Ex.  "I can't sleep, I just don't have energy, life is hard".

I'd fell more secure with a psychologist prescribing drugs for mental illness than I am with most GP who have a frame of reference that bias them toward drugs being the first option.
