i read on a post somewhere on here that you can make you own VG liquid so i serched Wal-mart for Vegetable Glycerin ok well in the pharmacy section they showed me a bottle of 99.5% GLYCERIN and 0.5% Anhydrous witch says its a skin protectant. also in the bottle its made by HUMCO and says USP. now can i use that to mix wit my flavors for a VG liquid?? like is it safe to vape??? i dnt see why not since the FDA sayz were vaping antifreeze....but jus wonderin if its safe or will it hurt me or poision me......thankx
