Just vape and quit worrying about the math You will know if you vape too much. If you start getting dizzy spells I would think that would be a great indicator. Sometimes I vape around 5mls a day some days when I am really stressed I probably go through a little more than that and I am perfectly fine. I would a whole lot rather be vaping than taking a drag off of a nasty analog
I have to agree with this. When i started i didnt care how much i vaped because i had the satisfaction without the nicotine overdose. Now i kind of limit it a little but no matter what i think vaping is great and way better than taking in all those chemicals. I just converted a regular smoker tonight when i was at the bar for a comedy show.
