I am a PharmD and current a pharmacist for 7 years. I tried to read through all the posts, but it seems none of you can explain why it is not popular to Spoons. MD/PHD designed for a graduated to do teaching and research (basic science and clinical) for 60-70%, and do patient care 30-40% plus, while is in training MD/Phd the students also get free tuition for 7 or 8 years and stipend too. This is an excited field, and exciting people to apply for it, while PharmD/Phd has none of this benefits.
In Pharmd/Phd program you do not start PHD until you finish P3. It mean that you still have to pay tuition for 3 years. Secondly, What you do any special thing after you graduated? If you want to do basic science research, simply you should just get PHD while bother to get Pharmd? any add on benefit? None. If you want to do clinical research, just get PharmD and then do residency. If you want to work at drug development then either PharmD or Phd and go for Fellowship. Getting both PharmD and Phd is a waste.
