superglue is a cyanoacrylate, a substance containing a Carbon-nitrogen group. Other items containing this group are HCN, hydrogen cyanide. I can't find any ingestion toxicity information in a quick search, apparently because the toxicologists figure that having lips glued shut is a bigger issue than the longer term effects of CN ingetsion. Go figure. They didn't anticipate crazy anita. Also: apparently super glue reacts with cotton (http://en.wikipedia.org/wiki/Cyanoacrylate) causing heat production, flame and burns. Might be an interesting addition to the fire making kit, subject to appropriate experimentation by Blast.
