You may be able to sue her for malpractice. Malpractice, as you know, is the provision of medical care which does not meet then-currently accepted standards for medical care. Opiates are a powerful, dangerous, and controlled substance; it is very  likely that prescribing them for a patient without examining him or her would constitute a deviation from accepted standards of care, and thus constitute malpractice. From what you write, it would be worthwhile for you to meet with an malpractice attorney to explore your possible recourse in greater detail. Good luck.
