I remember some authority mentioning that our Jacobson’s organ is present, but all the passageways to it are closed up. This likely means since the sense wasn’t present during early brain development, even if we attempted to use it (making / opening passageways) it likely would be a very dulled sensation, if anything.

Hey! My snakes have those, too!
And horses! Humans, too, but it doesn’t appear we use it.
