I had to bring my meds to the hospital when I was admitted for my gallbladder surgery a few years ago. I think we had to do the same for my husband when he was in for other reasons. The only delay was that they had to send the meds down to the pharmacy to have them verified as being what was in the bottle which seemed reasonable enough. And some were delayed prior to surgery due to surgical protocols. I didn't find it was discriminatory. In fact, having us bring in our own meds saved us money since the didn't have to call in another doctor to prescribe and more meds weren't charged to our bill.
