What flavorings do the big e juice company's use? We all know it's VG PG mixed how you want. I can take mccormick store bought stuff, evaporate the alcahol in a pan for 5 minutes, and it tastes great in VG or PG. IS THIS SAFE? I stay away from oils, but even in the alcahol and pg flavorings, they say there is oil? Thanks in advance...what is the truth behind the oil thing, and where does Space Jam get their flavors?
