Understood, but for those who worry about such things, it seems like one of the things they worry about so I figured they would go ahead and include it in the analysis. But I suppose the testing is per compound and would get more expensive...
Well, the thing is to go after the "most worrisome things" first.
I would suggest that anyone concerned about other stuff, and there is a lot of other stuff,
just start moving to unflavored.
You can do that slowly....I started cutting my vendor juice a year ago down by about 1/3, then by 1/2, then by about 3/4, so I got used to
vaping about 1% flavoring.

Now, unflavored tastes good to me, sort of mellow and a tad sweet.
I really never wanted to vape DAP but also not sucralose, dyes, food colorings, (or titanium dioxide!

) , but lord knows I did when I started until I gave it all some careful thought. So, unflavored pretty much removes those concerns, once and for all.
It really isn't hard and that is the only way to really worry less if you are a worrying sort.
I think the other thing, and I don't know if this is true for others, but once you are pretty much "off" worrying about smoking again, and you've vaped for a longer time, you tend to be a lot less dependent on the flavor chasing, finding ejuice perfection, etc. I mean, you can just vape and get by and be happy......or at least, that is what happened for me.
When you are in the throws of getting off cigs, and still in the danger zone, you probably NEED to vape whatever will keep you off the cigs.
