I smoked a pack a day menthol cigarettes for 45 years; along with cigars and pipes (had over 65 pipes in my collection at one point). I had tried to quit smoking cold-turkey a number of times over the years (I once made it to 9 weeks before returning to smoking)and most recently tried NRT patches and gum to no avail. During a 2 month period in 2009, I started using a small e-cigarette that resembled a cigarette in size and tried 2 different brands before finding one that produced the vapor and flavor I was looking for. I haven’t burned tobacco since 08/09/2009! I gave up cigarettes, cigars and pipes altogether; and never looked back. I started using a 510 e-cigarette with 36mg. e-juice (mostly tobacco and menthol flavors)to get off analogs and gradually went down to 6mg. over time; but under stress, went back to 12mg. when my Mom passed away (from Lung Cancer in 2011). I continue to vape 0 to 6mg. e-juice; however, I now prefer Coffee, Tea and Fruit flavored vapes for the most part. Over 4 years of vaping means my breathing/sinus problems all but disappeared, my taste buds have come back and everything smells and tastes much better, my overall health has improved with fewer colds and respiratory/flu-like symptoms; in general, I feel (and smell) better. I have found through personal experience that Nicotine, although in itself an addictive substance, is not the primary problem with why I continued to smoke for so many years (why else could I go from 36mg. to 6 or 0mg. e-juice). There are more than 4,000 compounds in tobacco smoke (mostly carcinogenic and possibly way more addicting than Nicotine) accompanied by the psychological / habitual act of smoking (something in my hand, something to puff on, seeing smoke/vapor exhaled) cannot be ignored. Although there were a few studies conducted in New Zealand and Germany when I started vaping in 2009 to indicate it was a safer alternative to cigarettes; the new scientific research (2013) primarily coming out of Greece, Italy & the USA confirm that E-cigarette vapor is much less harmful than smoking tobacco with no second-hand consequences to others. This again bears out my own personal experience over the past 4 years; I quit smoking, but haven’t given up vaping. I ENJOY vaping, which leads me to believe that the psychological / habitual act needs to be examined in greater detail.
