I also am dealing with 100mg nic and am wanting to cut it down to safe levels. I originally bought 36mg nic in 100%pg with the thought that I could cut it in half and have the 18mg target that I vape. I did not think it through enough though, because even though I could easily obtain the desired 18mg strength, I usually vape 50/50 mixes and that I cant get with the 36mg. I ended up having to make 70/30 and 60/40 because the nic is in PG and so are my flavorings. My question is, what would be a good mix for base that would make the handling of it safer but still leave room to play around with the PG/VG ratios. 18mg is what I want and most I want to be 50/50 on ratio
