Unfortunately, there aren't a whole lot of doctors who are willing to write the recommendations--no matter that their patients qualify under Michigan law. Sadly, these same doctors have no problem writing prescriptions for harmful and addictive pills.
At any rate, I would urge patience in dealing with THCF. I suspect they are being bombarded with phone calls from people whose regular doctors are afraid to recommend the healing benefits of a simple plant.
If you happen to know of other doctors who are willing to write recommendations, please let us all know.
