How long were they without rh? After recalibrating a hygrometer(digital I assume) load up a humi and take a reading. There is a good chance you can slowly bring them back. 5% rh at a time and let them sit for at least a week before going up another 5%. Unless they were extremely dry for a long period of time this should revive them. Let them sit for a month or two at 60-65% and them give them a try.
At the same time take this opportunity to load up a cooler with new smokes,
"Just in case"
