Ok. I give in, here's my 2 cents.
Slippery Slopes
First, some general housekeeping of the side issues.
The right to self determination and responsibility does not come without heavy burden. Often, out of convenience (when the effort and time needed to educate ourselves in order for us to make informed choices on the multitude of issues that face us would leave no time for much else) or too often, laziness, we delegate those responsibilities. We elect representatives who, for the same reasons we delegated our burden to them, create agencies. I am adamantly opposed to promoting AEMSA as either a reasonable guardian of my health and safety, nor as a better alternative to government bureaucracy. If my choice is between a private exclusive member association or an agency that is held responsible to my elected representative, I'll take the later.
I'll skip commenting on the effort to force membership to AEMSA.
Secondly, the conundrum.
I can refuse to take the easy, knee jerk, route, which is to throw the Carrie Nation Crowd (CNC) what certainly appears to be an obvious bone (2,3-BUTANEDIONE/DIACETYL, etc,), BUT my refusal to make an offering would likely only result in giving CNC a stone upon which to hone their hatchets.
OR
I can try to placate the CNC and throw the bone. If I do, I do it knowing that without careful prior deliberation, I may have severely crippled myself in all future debates. That the standards by which I judged that bone to be a bone will set the precedent by which all further bones will be determined.
Next, the current issue of 2,3-BUTANEDIONE
Other than the setting of precedent issue, a ban (per AEMSA, if I read their rules correctly) of diacetyl isn't an Issue for me. I don't like custard, caramel, or buttery taste or feel in my juices. That's the reason for my intense dislike for Vita Bella. Even if I did like them, I think the current evidence concerning Diacetyl is sufficient that it would cause me to avoid them until further studies are available. But it should be my choice. As banning (or required disclosure) is the issue, I have some questions:
What standard is to be employed before we ban a substance? Is there no safe level at which it could be responsibly used? (Are there no studies, no studies of its affect on what must be thousands of short order and fry cooks who have essentially been vaping diacetyl for hours each day for years?) Is diacetyl, based on these unknown standards, so hazardous that a notification and warning that it is an ingredient insufficient?
Finally, relating all of this to NETs ( an aside: I think NTEs is more accurate, but I can't pronounce it, so NETs it is).
Whatever standards are used to determine the actions that are eventually taken in regards to diacetyl, will most certainly be employed when determining future actions regarding all other juice components. Health issues concerning diacetyl have only arisen in the last 15 years and studies are, at best, sparse. On the other hand, 60+ years of studies of the harmful affects of tobacco are voluminous and comprehensive. The one study that I am aware of that tested tobacco vaping juices is damning. No one with two synapses to rub together should conclude that NETs are not hazardous, leave alone, safe. I can rationalize, but I'm not stupid. If NETs are subjected to the same standards that appear to be employed regarding diacetyl, then it's going to be a closed and shut case for NETs.
Conclusion
Take the time to think before you act. Make rational, well reasoned decisions. Create sound, valid, useful standards that balance your/our concerns for safety with our pursuit of our vice. Otherwise, prepare to Play a game of Thermal nuclear War.
