question about e-liquids, first-PG means Propylene Glycol, a food additive used to dilute the nicotine solution delivered as a vapor,correct? VG is vegetable glycol ? how does that differ from PG ?is it really from vegetables ?? that sounds healthier to me,, I got my juice at the e-cig store, but on my bottle it just says 24 mg and nothing about PG or VG, on the valuevapor.com website thats on the label it says this is an 80/20 mix, 80 and 20 of which ? Also, when I am at the e-cig store how do I know if it is PG or VG, and what the mixture is in the bottle? I read on here that VG has more vapor ? Id like to try a VG liquid,do i just search for it ? does anyone have a preference for either? all help appreciated as always !!
