Excellent point, kristin, and one that needs to be made repeatedly to those new to
vaping who are anxious about
ecig health and safety issues. Too many people today have unquestioningly bought into the fearmongering so prevalent in our media these days. They seem to have forgotten that the poison is in the dose and cringe at any mention of "carcinogenic." It's essential as consumers that we maintain perspective on relative danger and relative safety.
Just recently the FDA hastened to reassure the public that the levels of arsenic found in rice were not dangerous. Too bad they can't apply the same measure of public reassurance to ecigs...
Another aspect.... my favorite toothpaste for a few years was crest pro-health 'night'. It's been discontinued - I scanned google quickly and osmosed ;-) that is was some chemical they no longer like or got some more info on. I don't keep up with that type of news but the product had been sold for years. I'm guessing it is not poisonous

but perhaps something that involved killing animals or plants in order to use

Whatever, but within the four years I've been here - WE - have found things that didn't work well, might not have been the best material, etc. and pretty soon there's a better solution. We self-govern for those who want to be informed enough to visit our forum. Others obviously don't care enough to inquire - where one might invoke Darwinism

But they TOO benefit from our efforts here, by the way we drive the products that are offered.
I feel sorry for the few instances that we've seen here where harm was done - I won't list them BUT they were reported immediately by those concerned and 'solutions' were offered and data was gained that changed behavior - vendors and manufacturers were contacted - some responded well - if not they were shunned by this community.
No one has a better view of the effects of the industry than we do. And we do something about it when needed. Pre-emptive actions by gov't's far removed from our experience ends in less creative and pertinent solutions. And less harmful solutions to ourselves and this industry.
