Oops, missed one of your ?'s. She was given the Adderall essentially because she asked for it. She has a work friend who has told her the wonders of the drug, and she took an online test which suggested she might have ADHD. She came in seeking it.
This same work friend is (I think) a primary driver in this situation. She is a divorced mother of 2 who recently met her new "soulmate." She has never been one to hold back her opinion so I am sure she is preaching the glories of divorce. They have recently become very close.
