Maybe this will help clarify a few things
About flavours.
I love the taste of cinnamon but real cinnamon toothpicks burnt and caused swelling on the inside of my lip. That experience made me wary about inhaling cinnamon into my lungs so I was hoping cinnamon flavour was made synthetically. Having looked up the above link I'm none the wiser to be honest. I suppose it could have been something else in the wood toothpick other than the flavour that caused the swelling but if it was to do with the flavour then presumably the same synthetic chemicals could damage my lungs .
Yes, thanks. That helps. Thanks much. I feel a bit better about it.
One should read the entire article, in particular the part that says they have to use many of the same chemicals, but to quote a specific part:
So is there truly a difference between natural and synthetic flavorings? Yes. synthetic flavorings are simpler in composition and potentially safer because only safety-tested components are utilized.
That, of course, is not to say I think all these flavors/chemicals have been tested for vaping. Still, that quote is encouraging. It (synthetic flavoring) is more within my personal comfort zone than the alternative, even if the flavor isn't "spot on". That's OK with me. The thing is... people selected these chemicals with good intentions and with the understanding that they will be consumed by people (OK, it's vaped and not ingested... a big difference I assume, but still better odds).
I guess, for me, it's still a crap-shoot, but favors vaping being better than chew/snus/smoking, and synthetic tobacco flavor being likely to have fewer (if any) "nasties" than TA type extracts (if they even have them). I guess I have to trust the flavor makers mixing the stuff to use their best judgement, and hope for the best.
I'm glad I can still have a tobacco flavored vape, mix my custom RY4ish, and enjoy it, hoping that it turns out to be safe once we get some decent testing methods in place (and 20 years of data...lol).
This is my personal feeling and should not be an endorsement nor condemnation of any particular flavoring (because we don't know enough). No warranties, express or implied with this discussion. All disclaimers in full effect, and any others that I may need to invent.
