Oh no! Another health question concerning some juices

[tims]

What all juices have oil in them, I sure don't want to use them and find out, they killed my lungs after it's to late ???

I recently got some clearomizers, and the problem with some juices has raised some questions for me. If you put acidic juices in a clearomizer, such as orange, Atomic Cinnacide, etc, the clearomizer plastic will crack.

Which brings me to the question. What is it doing to our lungs? I know if eaten, the stomach has protection, but our lungs aren't as well defended. Of course, if you have a buildup of tar from analogues, I guess that would provide some protection.

I think I can lay this to rest I have had a couple crack on me but I do'nt use any flavour just straight 18mg 100% VG
I think after a bit of use with the heat generated they get a bit brittle and its always at the top by the heating coil .

Hard plastic tops on cheaper Cartomizers (or V4L's old cartomizers) with DIY Cinnamon Oil (included), or even commercially purchased (Atomic Cinnicide, etc.) ejuice will turn the plastic a but gummy and gooey. If you use it for a bit it gums up even more. It appears to really effect white plastic the most, I don't know why.

I know that PGA took off the paint of some of my 901 attys that were soaking back in my start of DIY.
Maybe related.

It looks just like the white 808D-1 caps becoming goo-like at initial separation point.

I know this is an old thread, but I find it very relevant. I'm not worried about the plastic cracking thing, as I use no plastic tanks, but I'm very interested in the health aspect... I now won't vape cinnamon flavors, I think Kurt is totally right about them, even though some folks seem fine with them.

I had been wondering why essential oils aren't a good idea, and I found the answer. It's supposedly because essential oils mixed with alcohol (pg/vg) = esters, which are bad...

So would simply extracting mint leafs in vg have the same reaction? Or what about ginger?

Or is extracting the oils from anything just not a good idea, as it may create esters?

EDIT: Let me know if I'm not being clear enough... I just think this stuff is really important, and I'm trying to get a handle on it.

Esters in of themselves are not necessarily bad. Banana, pear, grape, rum and many other flavors are esters. But like alcohols, there are those that are ok for ingestion, and those that are not. Ethanol is not nearly as bad as isopropanol, and there is only one carbon difference.

Water-insoluble oils tend to dissolve things better than water-soluble flavors, as has been experienced with cinnamon oil here. Clove oil is similar in this respect (grind up some cloves in a plastic-lidded coffee-grinder, and see what it does to the plastic). Frankly anything that dissolves plastic is right out for me and vaping.

My advise is to stick to water-soluble flavorings. Essential oils may be "natural", but if they are water-insoluble, other problems from inhalation can arise. Not talking about reactions to form other compounds, just talking about insoluble oils themselves...if they do not dissolve, then they cannot be easily expelled.

There is a general belief here that flavorings should be all natural, and come from natural sources, like fruit extracts or essential oils. I completely disagree with this, because inhalation is NOT eating, and simple water soluble molecules that have a good food safety record are the lowest risk. The issues with inhalation make this especially important.
