Just felt like I needed to share this.
A couple months ago, my son and his fiance came out for a visit, and my wife's BD. The young lady was in the process of quitting smoking, as my wife would like to do. One thing led to another and my son's BD present to his mother was a vaporizer.
After a few days, and me continuing to chain smoke, DW asked me if I would be on board for quitting also, if we got me one of these newfangled gadgets, but only if I was serious, and not just because I'm a technofreak. I said sure.
Well...it's been 60 days now, and I have not touched a cigarette (or other tobacco product) since 2 days after I started vaping. I don't have the slightest desire to ever fire up another cancer-stick again! I transitioned from cigarettes (a 50 year habit with only one 6 month break) with apparent ease. I traded cigarettes with their ~1,500 chemicals for just 3: propylene glycol, glycerine, and 2.5% nicotine.
The first thing I noticed after 5 days was that I woke up in the morning and could actually draw a full lung of air with the firs breath. No more taking short, measured breaths to inflate my lungs without hacking my guts out!
The next thing was less shortness of breath during a day's activities.
The third thing was more energy (which I ascribe to better oxygenation of my blood).
The other Pros I've discovered are:
1) No more tobacco stains on my fingers, or smell on my clothing.
2) No more ashes or tobacco flakes where ever I go.
3) No more cigarette burns on carpet, clothing, or other valuable articles that got in the way of a "lost cherry" from my smokes.
4) No more "2nd hand smoke" to freak out non-smokers, and those folks seem to be more curious than offended.
When I get into something new, I like to know as much as I can about it. I've done more research on "vaping", and learned more, than I ever imagined I would.
I had a 2-pack-a-day habit, and the only way I could afford it was to roll my own. Actually, I had a machine that stuffed ready made tubes with filters with pipe-cut tobacco. I was still sucking down chemical-laced tobacco along with the paper by-products.
This is the device I started out with, and my soon-to-be DIL didn't steer us wrong. Technically it's called a sub-ohm carbonizer, which means it uses a very low resistance heating coil, which vaporizes the "e-juice" at lower temperatures and lower wattage, so the juice and heating coil last longer.

Switching from tobacco to vaping has dramatically changed my life.
I'm open to Q&A on the subject.
