Thanks Scottes!
In a brief - each person nicotine absorption is different based on so many factors, but the main consensus is that we , while
vaping, absorb approximately 10 times less nicotine then through smoking the real cigarettes.
I vape 1.5 ml of 12 mg a day (used to smoke 15-18 Ultra Light cigarettes), so it equal to 18 cigarettes but bring in the absorption rate and it become equal to about 2 cigarettes a day.
How is this possible that I am vaping the equivalent of 2 cigarettes a day and completely satisfied?
Yes, it's sound unreal but while vaping the nicotine absorbs more efficiently through mucus, throat and whatever else in your upper respiratory system and delivered to your brain receptors (through blood) much faster than from lungs.
