I quit smoking after 40 years by starting Vaping. I went from cigarettes and tobacco pipes to Vaping overnight. And it was not easy. But after a few days, I had no desire for tobacco products anymore.
I think the health benefits of vaping of smoking speak for themselves. I can't relate to "dual-user" as I never went that route, but I would heartily encourage you to give vaping, alone, a serious try for 30 days. By then you would be smelling your clothes, and ashtrays, in a way you probably cannot by now. And Food will actually taste good again. You might even be able to smell the cool, crisp pleasant air of the early morning within a month.
I don't know how old you are, or how long you have been smoking tobacco, but I can promise you if you continue smoking the best things awaiting you would be A) wheezing at night while trying to go to sleep, B) being out of breath simply climbing one flight of stairs, C) constantly coughing up substances you know don't belong in you body, and D) self-loathing for letting something control your life in such a way. Of course, the less pleasant results could include A) Lung Cancer (like my wife), B) Throat Cancer, C) emphysema, and D) Heart Disease.
Doesn't that sound enjoyable ?
I would hope that you give Vaping (alone) a serous try. You owe as much to yourself. Just my Opinion ....
