Next time you're in a grocery store pick up a box of any flavored tea. Problem is most flavor with oils, so really no advantage that I can see. It's possible there would be less (oil),
LOL, I have almost a whole cupboard full (well, two shelves) of various herbal "teas", ie actually teabags or pieces of plants for making tinctures or tisanes - chamomille, mint, fennel (both seed and flower), rooibos (unflavoured and at least 4 flavoured versions), rosehip, black currant and aronia, rosehip & hibiscus*, licorice root, more mint (grown myself, not very good) and probably some more I have totally forgotten about.
I grew up in a very tea-drinking family, but lots of the teas were actually tisanes - almost all real tea was plain black (I think the only flavoured actual teas I knew before I was 15 were Earl Grey and a chinese Jasmine tea). I have turned out to be a coffee drinker, but I have retained the habit of *buying* interesting tisanes when I see them. And herbal teas are very good things to buy as tourist souvenirs - consumable, doesn't weigh much in your suitcase, good shelf life, cheap. About 80% of my stash is probably from foraging in Polish supermarkets - those Poles love their Herbatka, and the assortment is fantastic.
Eh, what was the topic again? Oh, vaping!
Yes, I agree with you Bostonsnboxers, I would be rather careful about flavoured tea-teas.
Not that I believe that the minuscule amounts of possible oils (which are probably essential oils and not lipids anyway) one might extract along with the flavours are likely to be very harmful when inhaled - it just seems unneccesary to use an overly complicated product, if a simpler and purer one is available. At least when one is doing something with it not originally intended.
*One of the nicest herbal teas I've ever had was pure dried Hibiscus flowers. From Zimbabwe or SA, iirc. Very bright colour, and subtle taste (similar to rosehip, but more juicy) so I'm not sure it would be a good thing to vape, though.
