i believe it's alright for a couple days but eventually can cause skin problems. it also promotes mold and bacteria growth in the enclosure. i'd say try to figure out how to lower it down. what type of enclosure do you have? tub--> poke a couple more holes, aquarium--> i don't know how it got that high but move the water to the cool side. i'd recommend just turning on a fan to see if it drops it. i know that humidity at 65-70plus is only alright for the couple days when your snake is in blue or time between until shed. maybe that helps? hope so. i'm sure a lot more people will follow-up on this.
