Do people really think the testing already done by the FDA and other labs doesn't matter? Most studies ARE based on "previous and similar" studies and those are used as evidence. Just look at the footnotes in most research publications - they ALL base conclusions on previous studies that are similar, but not exactly the same.
There is no proof that long term, extended exposure is safer than cigarettes, but when discussing "second hand" exposure, we don't need that proof - just proof that brief exposure isn't dangerous. There is plenty of scientific data on short-term, brief exposure to ALL of the ingredients in e-cigarettes and NOTHING to indicate danger. Are we now going to ban everything new that doesn't even have a reason to believe that they'd be a danger until proven safe? No - wait - only anything containing nicotine apparently, since other FDA-approved products don't seem to have to abide by that standard. Chantix was put on the market and promptly started killing users, so obviously IT wasn't required to prove absolute safety before getting the green light.
The FDA obviously doesn't require "absolute certainty" to approve a product and any possible dangers have nothing to do with the fact that they haven't "approved" it. In fact, they usually don't bother to get involved in non-pharmaceutical products unless enough actual adverse affects have been reported. THIS all about power and money - not public safety. If you believe anything else you have a lot more research on the history of e-cigarettes and what has been happening.
The fact of the matter is that the future of e-cigs will not be safe until they get enough public support and they won't get that so long as the public believes the lies of the public health groups and FDA.
I agree wholeheartedly with your assessment of both the FDA and big pharmaceutical. If big pharmaceutical were marketing ejuice that killed 1 out of a thousand users on the first puff, it would still have immediately been given FDA approval (after all, they get away with marketing products where the fast-talking description of side effects at the end takes as long as the actual commercial). If they can market a drug to prevent a runny nose that causes you to projectile vomit blood and urinate pure Clorox bleach, they can pretty much do whatever they want (please, no one ask for a link to the runny nose drug - I made that up).
And why do you keep ignoring the studies that have been done? Several tests and studies, INCLUDING THE FDA TESTING have not found any toxic levels of chemicals nor dangerous levels of carcinogens to give any reason to suspect that they'd be dangerous to by-standers or even to users. Three years of real-world use and no adverse affects reported by users or by-standers due to exposure to the vapor.
Please tell me with what other products have people insisted that a product may still be dangerous even though it had been tested and shown to contain no toxic levels of chemicals and no dangerous levels of carcinogens? What risk of "potential harm" to others is even hinted at with a product that has shown to have no dangerous levels of chemicals?
No dangerous levels of carcinogens detected. No danerous levels of toxins detected. No ingredients not already approved for human consumption. No aerosols not already approved for short-term exposure. No reports of serious adverse affects to either brief or daily exposure to the vapor in three years of real-world human use.
In what universe does this indicate that there would be ANY potential harm to brief exposure to by-standers, especially since in this universe products are typically not given such scrutiny until they actually have reported complaints?
Cigarettes are already proven to the public's satisfaction to equal death. Most distributors of PVs market them as e-cigarettes - in other words, a cigarette that's different. As the market grows, this is changing, but the most well-heeled advertisers still market a product that looks just like a cigarette. By doing so, they have deliberately invited the world to give the e-cigarette the same treatment as cigarettes.
The only, ONLY way to separate PVs from cigarettes in the minds of people is that 99% proof that they do no harm. Had they been introduced as a completely new and separate thing, this would have been different, but you're right, greed is rampant and they targeted the product to try and take market share in the vast smoker demographic (for which I'm personally happy, because I don't smoke cigarettes any more).
If this product was an air freshener product for public spaces, it would have already been approved for brief exposure in public based on the known facts. The only reason to oppose these as "potentially harmful" is politics and greed, not science. And the only reason to combat that is to get the general public to see that by exposing them not only to the facts, but to actual e-cigarette use and users.
If x=safe, y=safe and z=safe, there is no reason to believe that x+y+z=unsafe.
You're saying it's impossible to take 3 chemicals that are separately benign, mix them together, and add heat and have the end result be toxic?
Oh, wait!! You're saying testing has been done on every flavor distributed by every company, right?
The area I live in was moonshine country during prohibition. There are tons of stories (anecdotes at this point, I'll grant) where someone wanting to break into the business experimented with their recipe and ended up killing people (or making them go blind or have a permanent palsy or whatever).
In the absence of testing and regulation (and the FDA is in charge of that, corrupt as they are), there's no definitive way to say this isn't going to happen in the ejuice market.
If we were all vaping flavor-free pure PG, your 2nd hand exposure argument would be totally correct. I personally haven't met anyone who does this.
I still contend that any of us buying pre-mixed ejuice who tell people it's completely harmless is lying because we don't know what's in it and don't know what chemical reactions take place when that particular mix is heated. Even with DIY flavors, unless the recipe you use has been tested as a whole, we're still not sure.
As I've said, I'm totally on the PV bandwagon. It's the only thing I have ever tried that could make me put down cigarettes for a month with no pain. I'm also on the ejuice bandwagon. As I type, I'm enjoying some peanut butter cup flavor (don't have a clue what's in it, but it be tastin' sweet). If I went the next step and said it won't do me any harm or blew it in someone's face and insisted it would do them no harm, I'd be an idiot (see the don't have a clue what's in it).
