I started smoking fairly late in the game, I was about 28, 3 years into my military career. For me, smoking was more of a social thing, a means to get out of the workplace and socialize. I ended up becoming a stress relief, something I did more of when I was upset, etc. I enjoyed tobacco, the taste of it, the culture behind smoking. E-cigarettes became a thing at work for a few months. A lot of people were picking up the setups with a small eGo style battery (650 M amps), a non-disposable atomizer, and disposable, refillable tanks. I stuck with smoking until a friend who tried it, didn’t like it decided to get rid of her setup. I picked it up, tried it, stuck with it for a few weeks, but was ultimately unsatisfied with the flavors that were available to me, as well as the overall experience. Fast forward several months. Most of those vapors that picked it up because the cool kids were doing it had gone back to analogs. What remained were folks that had done their research and found a setup that they liked. I went with one of the faithful to a store, and, following his advice, I picked out a setup that was far more satisfying to use. Bigger battery, atomizer with replaceable coil/wick assemblies, better juice flavor selections. I still wasn’t satisfied with the flavors at the shop, but through the r/electronic_cigarette community on reddit, I discovered vendors that supplied far superior juices in both quality and flavor. Now I am researching the purchase of a higher powered battery assembly (that offers finer control of the power output) as well as rebuildable atomizers for increased performance and economy. I’ve done research on the actual ingredients that are in the juices. Granted, there isn’t much science behind it yet, but both propylene glycol and vegetable glycerine are FDA approved for human consumption, and nicotine itself is proven to be a simple mild stimulant with health effects similar to caffeine. I tend to stick with reputable juice vendors who have a reputation for putting out a good product. In my opinion, the potential ill effects of vaping (provided the vaper does his or her due diligence in sourcing their supplies from reputable sellers, and not doing dumb things like vape on 36 mg/ml juice all day and burn their wicks) are far lesser than inhaling the multitudinous known carcinogenic and generally harmful byproducts of tobacco smoke.
