I think my most recent previous post might not have been as informative to everyone else as it seemed to me when I wrote it. I was just off one key to left at times...
Anyway, replying to
@LysergamideLandscapes1938 , I don't think the hole is a problem per se. I don't think the doses are anywhere near what would depress respiration—I think that the respiratory depression that arises during general anesthesia is tied to one of the other things (I'm blanking on the name, but I'm thinking of the stuff that isn't K and isn't a benzo). That said, I don't know for sure, and I haven't consulted an expert yet. The general insight is that Fluorine often has magical properties in the context of anesthetic agents for some reason.
And yeah, 5 tonnes would probably run ~$20M...
