What is the fastest way to get an M.D. license? In other words, if you are medically trained but do NOT want spend the time going to medical school, what is the fastest way to get the M.D. license? This would be used for simple prescription-writing. So many physicians have such little knowledge .... it appears that many patients go to physicians and educate the phsyicians. All the patient really needed was the legal right to write a prescritpion. Is there a fast route to being able to legally write a prescritpion if you possess years of medical study?
