I've gotten some new juice that's 50/50 PG/VG. I normally vape around 70/30 PG/VG. I made the switch only because my vendor only carries 3mg nic. in the 50/50 and I wanted to try the lower level before going to 0 nic. Enough background..now the question: my imagination or not, but it seems like I'm going through more juice with the 50/50. Also I notice a big change in the volume of vapor. Can such a slight change in the formula make such a noticeable difference? Stands to reason, more vapor, more juice. Or is this my imagination?
