The lack of controls and regulations considering the potential dangers of e-liquids have be worried. I started vaping 2 weeks ago and I am completely off tobacco since day one. But I chain vape ... I agree with more controls and more regulations concerning e-liquids.
I need to know what I breathe.

OP ^
the production of analog smokes is not regulated, that is how they get away with the additives. frankly i don't personally care. since i make my own e-liquid, i don't really have a horse in the race. i think anything is fine as long as the companies are up front about what they use. but lets say i had no other option and had to buy my pre-made e-liquid, i would go with the vendor that is well known, has lots of info about the product specifically chemical analysis. and seems to take pride in producing quality products. i starting making my own e-liquid 2 months after i quit smoking and started vaping before that i was using "totally wicked red label" i would still use totally wicked today i use some of the flavors they sell in my DIY e-liquid all the time.. (still smoke cigars once in a great while so i did not really quit smoking, just smoking cigarettes)
some of the "e-liquid tobacco flavorings" are the same flavors BT adds to the tobacco at various stages.
black licorice is a well known flavor BT likes to use. with the right growing conditions and fermentation tobacco can produce some pretty nice flavors. BT does not want to pay the price for 10 year old exotic tobacco only to grind it up into cigarettes. the wrapper / binder leafs in cigars have been aged for at least 2 years. to give you an idea i have one cigar right now that has a wrapper leaf from 1990 but was rolled recently in the last few years. another one of my favorite cigars is from 2001, the entire cigar has been sitting in a cedar vault or my humidor for 13 years. getting decent flavors from tobacco takes time and that sort of thing commands a high price that BT is not going to pay, so that is why they add flavors and other things.
seems like people are looking for a "Guilt Free" smoke in the e-cig. people lie to themselves and others when they say "vaping is safe or harmless". all of this talk about flavorings being bad had me thinking about this subject. heating up a liquid and inhaling the vapor is not healthy, is it better than smoking tobacco? sure, but its not totally safe. nicotine alone can present some side effects. an elderly person i know had back pain so bad he could not move the doctor gave him some pain meds and told him to stop using nicotine because it constricts blood flow and he did, a few weeks after he quit he was up walking around... never used any nicotine product again says his back pain is almost nothing. he says when he craves nicotine he just goes for a 20 minute walk around outside.
inhaling anything other than clean air is not good for humans. obviously there are some exceptions like when its to administer a life saving drug. but recreational smoking or vaping even 0 nicotine e-liquids is never going to be considered a healthy or even harmless thing to do.
i understand that e-cigs are about harm reduction, and people are looking at the safety of inhaling flavorings. seems like a good place to start trying to improve. the heating coil and wick design works well enough but is overheating and breaking down some of the chemicals (this is why wicks gunk up) Vibrating Mesh Technology is something i have been looking at for a while now but it just does not produce smoke like vapor its more a mist.
