9.5 year vaper here. I smoked for 25 years. My mother died of lung cancer in 2009. I decided to quit. Nothing I tried worked to quit until I found e-cigs in 2010. Have not smoked since Jan 2011. I mix my own liquid. I was an early adopter and turned many people onto vaping.
My wife and several of my friends switched from smoking to vaping after I did and were able to quit vaping and nicotine completely after a year or two. Most had tried lots of other methods before vaping too.
I still vape. I’m not overly concerned by nicotine. I’ve been vaping the same mix for 7+ years and buy all the ingredients from labs and flavor companies, so I know what’s in it and I know that my health has drastically improved in the last decade. I’ll quit nicotine when and if my live allows for a couple weeks of mild nicotine withdrawal.
From my second-hand but direct experience, quitting vaping is MUCH easier than quitting smoking. I know what my wife was like when she tried to quit cigarettes and I know what she was like when she quit vaping and the difference was NIGHT AND DAY. She also claims it was much, much, easier to quit.
Here’s my speculation. I am unsure how much is backed up by clinical evidence The addictive potential of a drug depends on its delivery. Coca, cocaine, and crack are all the same drug, but they all represent different methods of ingestion - eating, snorting, and smoking. Eating is the slowest method and is least likely to cause addiction, smoking is the fastest and therefore most addicting.
Nicotine works the same way. The faster it hits, the more addictive it is. Nicotine gum is not particularly addictive - which is why it has some value in smoking cessation. Smoking nicotine is obviously extremely addictive since the smoke carries it directly into your bloodstream via the lungs.
Vaping, from what I understand (and feel subjectively) allows the nicotine to enter the bloodstream primarily through the mouth, throat and sinuses, which seems like it would provide a slightly slower onset of the effect. The vaper might even get more nicotine per puff, but that 30 seconds to a minute before it hits feels like twice what it is when you smoke. I’d put vaping addiction potential somewhere between eating and smoking. Simply put, this makes vaping easier to switch to if you smoke than gum, and easier to quit than if you tried to quit directly from cigarettes.
Anyway, my two cents.
