Scary knowledge of poisons?
The good news is that I also have knowledge of antidotes.
Eg, poisoning by nerve gas is usually done with administration of atropine, found in bella donna as well, but higher atropine and lower scopolamnine can be found in datura. (Aka, jimsonweed, moon flower) the jimson weed is comonly abused as a psychoactive due to its tropane alkaloids.
If given the choice between death and wild, psychotic, and terrifying hallucenations of having insects under the skin and having the devil come to dinner, I would choose the latter.
As with all medications, the lowest possibly effective dose is what you apply.
As I pointed out, I had a rather disturbed childhood. My dad was a medical corpsman in the korean war. He's never been right upstairs for as long as I can remember. Still, nothing quite like getting military issue improvised munitions manuals, and battlefield surgical training (living on a farm, injured animals are a harsh reality. I've sewn up plenty of gaping body cavity wounds, just not on people. I hate it. I could never be a doctor) as a consequence of a disturbed but loving dad trying to prepare his kids for the world.
I know about 7 different ways to create IEDs, how to hotwire a vehicle, the finer parts of poisons and antidotes, field surgical techniques to stop bleeding, repair mutilated arteries, and control infection, some scary dangerous pyrochemistry, and bizzarrely semi-useful things like how to tie thatched rooves, pitfire ceramic earthenware, make rope, start fires, identify edible plants and how to cook them, and all that jazz.
I think I could probably do a youtube "survivorman" knockoff fairly well.
All in all, I really don't resent my childhood. While over the top, scary, and completely detatched from civilized social mores, dad's stark view of "the real world" has left me very hardened against political rhetoric, psychological shock, and has pretty much destroyed any culturally programmed "learned helplessness" in my psyche.
By all accounts, I could well be described as being quite mad, I suppose. I've certainly never been accused of being "normal". I don't consider myself dangerous, as I have neither the desire, inclination, or motivation to employ the vast reserves of that "education". It's nice to know, in a twisted, paranoid, and horrible way. If I *needed* it, it's there, waiting. But I hope to never ever open the doors on that sordid little pantry door, if you understand me.
Having been in nitty gritty circumstances, I know I can work under pressure of imminent fatality (having experienced), and the conditioning I got allows me to just act, rather than freeze up with terror. That alone is worth the psychological eccentricities.
Personally though, I would rather of had kodkod's vinter's education.
What would I take in trade for aspirin, soap, and medications?
Hmm... metal trade goods of a utilitarian nature. Kives, cleavers, axes, that sort of thing. Tanned leather and spun yarngoods are good choices too. Depending on availability, I would probaly buy seeds as well.
