Does anyone know about the so-called drug induced zombies of the carribean? Sounds like total bullshit, but can't find any actual information either way.

This is what I am guessing is an urban legend brought to me by a Puerto Rican friend of mine. Obviously she has never seen it, and doesn't know anyone who has seen it, but it is (to hear her tell it) widely regarded as the truth in that region.

I found this article from abc that offers a nice but awfully far-fetched story

Followed the dr. Wade Davis in that article to Wikipedia, which told me tetrodotoxin was the drug in question. Following tetrodotoxin, I found this reference that says it has not been substantiated, and largely has been dismissed. But, I can't read any of the papers as far as I can tell, so I'm hoping one of you can shed a little more light on the subject for me.
