Dear Zoli
This is just my opinion. As I’ve explained above, I think there’s no problem with any of the flavorings, or damage from condensation/buildup, if the flavoring is used appropriately (MTL, DTL) and the user takes care of proper maintenance to keep the heating chamber as clean as possible. I have an acquaintance who has exclusively vaped dessert flavorings in MTL for over a decade and runs half marathons, regularly goes for check-ups, and is actively involved in sports. All flavorings are ideal if the heating chamber is clean and used and maintained with the right mindset.
