Leave in a safe secured weather free place outside.......screened porch on a nice day with you on porch relaxing type

. Time, exposure to fresh air will reduce the smell.
Get some smoke off spray like Febreeze or something, unscented type.
.......don't play anymore smoky places
Takes about 3 days for my gig bag to be allowed back in my room after a smoky gig, it dissapates on its own....
