Everything you tell a doctor is public record to be used against you. I don't want this to sound like I am anti medicine or don't think people should be able to receive treatment, this is just a fact of life if you live in an authoritarian society like the USA. All the stuff about doctor patient confidentiality is total bullshit and they have a legal requirement to report you in many cases which can be expanded at any time. I'd never tell a doctor I used drugs, I smoked, I had any unhealthy habits, or had any sort of forbidden thoughts. Treat doctors like cops and only tell them what you'd be comfortable with the police knowing. You have a right (for now) to remain silent.
