I started using an electronic cigarette (vaporizer) in December 2013, and haven’t had a cigarette since. I smoked for about 20 years prior to that. I looked into vapeing after reading some of the science behind it. I read some really informative articles, ones that listed the ingredients, which are far far fewer that those found in traditional cigarettes, which have hundreds of chemicals, either in them, added, or used in their manufacture. Many of which are known carcinogens. I won’t deny that what kept me smoking all those years was the enjoyment i got from the nicotine buzz of a cigarette. Its the reason why people smoke in the first place. Ecigs have only a handful of ingredients. Water, glycerine, propolene glycol (used in medical inhalers and air filtration systems), nicotine, and artificial flavors (used in countless foods), heated to produce a vapor. Nicotine is comparable to caffine in its effects on the body, so the point is i now get my fix in a smoke-free, less harmful way. I can regulate the nicotine quantity myself, and i don’t feel the need to have a whole cigarette’s worth, when i used to smoke cigarettes, i was sure to finish the whole cig. Now, if i just want to inhale once or twice, i can do that. And i also like the fact that it costs so much less. A $10 bottle of e-juice lasts me all week.
