In double-blind clinical trials, is there a common drug put into the placebo group and the test groups drug to test to make sure the participants are taking the drug correctly?

I understand that the administers of the drug are blind, and can't know WHICH group you're in (placebo v. active drug), but is there a way they test your urine to know IF you're taking the drug?
Perhaps somebody has worked in clinical trials or participated in them and knows.
This question is purely out of concern that I didn't report a few food allergies I have and I'm concerned they might put something else in the pills to make sure I'm taking them.
