Can vape shots be used without adding nicotine?

I've recently quit smoking cigarettes and been using a vape to help me. Today I bought some eliquid but got the wrong 1 it's a vape shot (brand name 88 vape and says 75% VG) it says to mix and add the nicotine, but I was wondering if it is safe to just put the liquid flavour shot into my vape without mixing in or added the nicotine?
