That's a tough question. Are you talking about nurses or chiropractors? I'd say chiropractors are pretty toxic-- just go to a masseuse or a physical therapist for the lower-back, random-aches-and-pains symptoms that medicine, unfortunately, cannot currently heal, rather than someone who's going to whip out 16th Century style, non-scientific myticism to make you feel better. I also remember getting a brochure about naturopathic medicine when I was applying last year-- that should also probably be outlawed as quackery.
