So, I was curious about how serious a poison super glue actually is and what I found was reassuring, so I thought I'd share it in case people are still freaking out:
"Mouth
If lips are accidentally stuck together, apply copious amounts of warm water and encourage maximum wetting and pressure from saliva inside the mouth. Peel or roll, (do not pull) lips apart. It is almost impossible to swallow cyanoacrylate. The adhesive solidifies upon contact with saliva (moisture) and could adhere to the inside of the mouth. Saliva will lift the adhesive in 1-2 days, avoid swallowing the adhesive after detachment."

Fortunately it was a stupid poisoner.
