Is there a cinnamon liquid out there that works with the stardust? The drip tip is melting and the tube is getting all cloudy.

but not so sure it's safe for me 
I have cinnamon fireball from ecblend that has also damaged the bottom of the driptip of my stardust. The tube hasn't been affected though. This the stardust with the new tubes. I don't have the rebuildable one yet. I figure the safest way to vape this is a vivi nova, metal tank and stainless steel drip tip. Safe for the equipmentbut not so sure it's safe for me

I remember reading those too. I think it had to do with cinnamon oil being used as a flavoring. Actually, I found it too strong to inhale, so just held it in my mouth before blowing it out. Love the taste, but won't be ordering it again.
and thisI think the issue here is not acidity, it is the nature of the oils themselves. Cinnamon oil (cinnamaldehyde) can leach plasticisers from plastics, and will dissolve some plastics, both can lead to cracking. Orange oil can do this too. Anything that is good as dissolving grease can do this to plastics. Its what is in orange cleaner products.
And yes, they are also implicated in lung damage, especially cinnamon. Many here get mouth and throat irritation or mouth ulcers from cinnamon juices. Actually, IMHO it should not be sold for vaping. Aldehydes in general are problematic, but cinnamaldehyde especially so. Its rather corrosive. Some have no problems with it. I can't do cinnamon hardly at all, even candy. It will make my mouth raw.
Acids are actually less a problem for most plastics. These oils are in general not acids, but they do interact with plastic and plastic components. Clove oil is another plastic dissolver. Try grinding some cloves in a coffee grinder with a plastic lid and see what happens, if the plastic was smooth and shiny before grinding, it won't be after wards...it will be etched...then imagine this happening in your lungs. I don't know about the mint oils, but the citrus, clove and cinnamon oils can be a problem
MrNate: in theory you are correct, that cracking plastic is not necessarily an indicator of lung damage, it could just be thermal effects. And I do appreciate the rigor of trying to separate and understand the effects. But it is known that cinnamaldehyde is dangerous to the lungs. Don't have the links at my disposal now, but it is known. And there is a big difference to me between leaching plasticisers, which leads to cracking of plastic and makes you vape plasticisers too, and etching plastic, which is a breakdown of the polymer itself. Plus the lungs have their own surfactant, and inhaling others, like citrus oils, can disrupt that important barrier, if not dissolve lipid bilayers, as in cells. Lots of bio stuff dissolves in them, as well as some polymer compounds, as Katya said.
But, hey, for some these flavors are just too important, and thus vaping them, regardless of risk, is rationalized to be imperative. They are all legal, and people can vape whatever they want. Yes, I am a PhD chemist with 30 years of advanced training in physical, organic, biophysics, bio-inorganic, and theoretical research and teaching. I personally will not vape these oils, for the many reasons I and Katya have stated, based on my knowledge of them chemically, and the tissues they interact with. I don't think any of these are implicated in irreversible lung damage, like that caused by diacetyl, but there could be incremental and sustained lung impairment, which I thought was what we were trying to avoid by vaping.
Flavors are the Achilles heal of vaping, in my opinion. There are many wacky flavors out there that use compounds which are fine for foods, like meat flavors, but use compounds like organic acids, aldehydes and long-chain esters which really have been shown to be a significant risk to lung tissue, similar to diacetyl.
like i said ill look into it and check it out for you all
