According to the AMA physicians have an ethical obligation to report impaired colleagues. Actual legal duties vary by state. So you do have a duty just not necessarily one that can result in sanctions against you. I don’t know what the California rules are and this is not legal advice. See your own lawyer for advice. I mean at some point there has to be some duty if you’re a surgeon and your anaesthesiologist is shitfaced, can you just ignore it and go for it? No.
