These are complex and comprehensive questions and, if you really needed answers to these questions, you would need to retain counsel and pay for that quality and quantity of legal work. But you don't really need these questions addressed. What you need is sound practical fact-specific guidance, so here is exactly that: leave your mj recommendation entirely out of your dealings with the school about your drowsiness. In fact, leave your mj recommendation out of all discussions and interactions with your school administration. Out as in O-U-T. No good can come of trying to manage or control that issue in the context of a college's authority to administer the rules and laws applicable to its student body. None. Leave that dog in the kennel. You can deal with this conflict in some other way.
And, by the way, the "drowsiness because of mj" story is not really persuasive. The world is full of persons with mj recommendations who are not drawing authoritative attention to themselves the next day. What really gives?
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
