What programs definitively hair tests for residency (and which don’t)?

Title. I am trying to create a Google doc which I can post publicly for all future applicants. You can just DM me if that’s any safer. Right now I know definitively that all advocate programs do hair and the only academic center I can find that does is MCW. This is ultimately beneficial for all applicants, because someone who doesn’t indulge would miss out on a program due to someone who gets their offer rescinded (unless you end up SOAPing).

EDIT 1/31/25: I basically only received information from this thread. Based on that, I don’t see a purpose in creating the spreadsheet. If you want to discuss anything further, please DM me. I will leave this thread up, at the cost of being called a drug addict, because I believe applicants do deserve the right to know this information. From my own research, it appears there are no major academic programs which actually do hair tests because as others have said, it’s expensive and they have too many residents to take on this cost.
