Second question....I have researched and hope I have this right. Ingredients in e-juice...PG,VG and nicotine, flavoring? Does the ratio of the PG and VG matter? Is the PG safe? I know this sounds silly cause, there are a lot of things not safe in things but are still consumed...but is it relatively safe. Is it best to have the VG ratio higher or not? Thanks again for all the help. Will post again later...
