Hmmmm... I sure have known some who would...but I didn't think of them as very professional. Medical Doctors do this... and "shrinks" meaning psychiatrists ARE medical doctors... so I guess it could happen.
You can always find a compounding pharmacist and let them test one of your pills, to see... if it wasn't labled a way they could tell visually.
I have often told my MD, I don't care what you give me... I don't care if you think it won't work... as long as it helps, I don't care... don't tell me if it's a placebo if it helps... all I want is the relief... at any rate!
