It still takes a bit to get used to. It's a totally different experience and one thing I can easily say is that you won't even notice if nicotine is present or not until you have vaped for some time and find with nic warmer vape and less flavor of the flavoring!
The real draw to tobacco is the memory of tobacco flavor over nicotine itself. Once you have vaped for some time whether tobacco or other flavors the memory of that experience will change how smoke feels to you. You will no longer smell like an ash tray or feel any tightness and irratation in the chest and passageways but refreshed at times! Vape'n'Coffee anyone?!
Another thing to note is the research funded for a private study on contaminants if any was seen to by an organization looking at Tobacco Harm Reduction as their main goal and even getting petitions going to present to law makers and the FDA. That's one of the active groups in that area. The result at one medical university was a 22 page Tech report indicating no pollutants or long term side effects found. Compare that to over 4,000 chemical additives, 68 known carcinogens, and a whole lot of other crud in smoke!
Once I quit another discovery of course was the costs! Instead of $300 a month based on $100 approx per carton as I was gradually reducing how much I smoked at one time 3 packs daily back in the 70s working long hours with long break during those old yes you can days before public bans came about I dropped in recent year to under a pack and then by the time I was updating hardwares under a half pack!
Try only 3 packs a week before the last came. Since I didn't need to build a new case still running 7 I ended up with $$$ to spend and still far less on vaping. The costs on both the obvious change of product lines and health overall a great investment!
