As you will guess, these classes are inhumanities electives. Very popular.
Non-Treatment 101 teaches doctors how to keep a patient coming back for follow-up appointments and, without actually doing any healing, charging patients and insurance companies for a wide variety of "healing services." A good Non-Treater can keep you coming back for years without helping you at all. The very best can also sell you a lot of drugs you don't need and for which there is no generic equivalent.
Non-Treatment 101 is a prerequisite for the more advanced Non-Treatment 102. This class is complicated to explain (med school courses are for the superior of brain and often difficult for us laypeople to understand), but it's basically this: How long can you keep the patient sitting in the waiting room, then the exam room, before you deign to sell them ten minutes of your distracted time for several hundred dollars?
Non-Treatment 102 is popular because it's purely recreational. It doesn't create income for the physician or for the drug companies, but med students and doctors report emotional rewards: in a stressful profession it's pure joy to peer out into the waiting room and watch all those unhealthy, unhappy people check their phones, stare at the ceiling and try to get comfortable in the office chairs as their pain and suffering intensify.
