I smoked moderately for about 5 years, at about 5 cigarettes per day. For me, with my weak constitution and at 130 lbs as a man, even that small amount of smoking had noticeable negative effects, such as exacerbating my difficulty breathing. That was in addition to the foul taste in my mouth and the smell. I was introduced to a counterfeit eGo cigarette and paid over $400 to smokekingcigs.com (855-282-3244) Even though the battery leaked from the button, it worked for a couple months. Then I purchased authentic products for 10 times cheaper at IndyVaporShop.com, and their products work much better. Anyway, I no longer crave smoking cigarettes. Vaping is awesome, and since their is no smoke flooding your lungs, it is so much healthier. The reason cigarettes are harmful is because of the smoke and tar, not because of nicotine, which is harmless, and even beneficial (the benefits of nicotine are well-documented, but of course you don’t see them published on billboards everywhere. Ecigs have zero smoke and zero tar.
