It really depends on how much you
vape. I seem to go through about what most people say they do and that's about 2ml per day. Some
vape more, some less. If that turns out to be your average, then after 6 days your bottle should be a bit more than half full, meaning that you've used about 12ml out of the 30.
Oh, and I was just over a pack a day when I quit.
