I'm getting my info from the bureau of labor statistics which states that PA will grow 30% from 2018-2028. I can see why that is. PAs are much cheaper than MDs (Of course they don't do everything an MD does). Where as pharmacists are restricted to either retail pharmacy or retail pharmacy, PAs have a wider range of job opportunities. Not to mention PA is a 24 month degree with half the tuition.
The main thing i have noticed while talking to prepharms, is that most of them do not have any work experience. Almost all pharmacy schools require no pharmacy experience where as PA schools require at least 1000 hours of health care work experience whether it being a nurse or EMT...
The prepharms think they will be doctors in 4 years making $150,000+ a year. Although there is some truth to that statement. Pharmacies are not going away any time soon. If a prepharm has connections and can land a job when he/she graduates, pharmacy is an awesome profession. If you have no experience working in the pharmacy what so ever, you will be in for a shock when you start working as a pharmacist (If you will find a job). I would say drop out now and save your wallet if you can.
