crafty cigarette case

[sailing-alone.livejournal.com]

okay, i'm not a smoker but my friend is and i'm decorating a cigarette case to give as a gift. i know it's safe to use modge podge and a clear topcoat for images pasted on the outside of the case, but is it safe to use on the inside? does anyone know if it would tamper with cigarettes stored inside at all, or possibly be toxic?

any advice is welcome. thanks!
