Quitting cigarettes

It’s my first day quitting and I have before quit smoking without much torture with the help of e- cigarettes. However I do have a few question toward AVA and current vapers and I expect an honest answer. I do believe that vaping is healthier substitute to actual cigarettes that contains harmful physical chemicals that can build in your lungs and blood like tar. However I realize I am still ingesting chemicals through e siggs , so what are this chemicals ? What is contained in the flavor and how do I find a more natural flavor. I cannot find an answer anywhere , and what is the effects of this chemicals on the body ? I do agree however that it’s less harmful effects than cigarette.
