"absinthe can cause convulsions, hallucinations, and psychotic behavior ...
the toxin, alpha-thujone, blocks brain receptors for gamma-aminobutyric
acid, or GABA. Without access to GABA, a natural inhibitor of nerve
impulses, neurons fire too easily and their signaling goes out of control."

I don't know if vermouth is currently made from wormwood, but it definitely
used to be: The word "vermouth" comes from "wermut," German for "wormwood."
