i've watched videos on making DIY liquid for my ecig, but now that im looking for a vendor to order supplies from, everywhere i look the nicotine has to have either a PG or VG base. doesn't this effect the PG/VG ratio in the liquid i make? another question i have, some bottles of nicotine i find online say things like "100mg nicotine", does this mean the liquid i'm making is going to be 100mg liquid?
