Regardless of the profession and who calls who what in the end they all have the same level of education. Physicians = 4 years = MD ; Pharmacist = 4 years = pharmD; dentist = 4 years = whatever they are called; optometrist = 4 years = blah blah blah.
So in reality, each profession has it's own expertise and ARE ALL QUALIFIED TO BE CALLED DR. If a nurse has a PhD, then she is entitled to be called Dr. as well and to tell her that he/she isn't is a false statement. Once the old BS degree pharmacists die off the newer pharmacist generation will be called doctors as well as they obtain residencies and provider status. If anyone laughs at you for being called a Dr or calling yourself one, just show them the PharmD and ask, what does this stand for and walk away. Should shut them up pretty quick.
