Are Kupo Nuts inebriating drugs? Are they addictive?

[PondHollow]

I've been wondering whether Kupo Nuts get moogles high (like inebriating drugs do). This is a theory I've seen elsewhere, in an attempt to explain why they get lost so often.

I don't mean to cast aspersions on the moogles; unlike many, I loved the moogle quests and find Moghome's residents utterly charming.

What happens when nonmoogles eat kupo nuts? Do we have precedent for that?
