Might be a good Idea to cover pharmacecuticals. For a worst case situation, people might like to know that antibiotics can be aquired from pet stores, diphenlydramine, (benadryl) is not just for hat fever and allergies, it is also common in motion sickness pills, sleep aids, and night time pain relievers. That makes it an over the counter sedative, among other uses. Ibuprofen may not be the best pain killer but it is a pain killer that is also an anti inflammatory. I can go on all day with examples like this, and I know not every one had the chance to serve as a combat medic or corpsman, so it might be interesting to teach them something that they can use in everyday life not just in a worst case scenario.
