If it's setup to actually keep its contents humid, then Weedhound is right... you definitely don't want to use it. Keeping buds in a humid environment is just asking for mold to develop. On the other hand, if it is simply a cedar box (with the humidifying piece removed, or allowed to dry out completely) then a good humidor would probably be a nice place to dry/cure buds. I've always wanted to try it, but my humidor reeks of Dominican maduros, and I didn't want to pass that smell off to the buds.
