LIST OF INGREDIENTS
Tobacco Companies’ Combined Ingredients List For the U.S. Department of Health and Human Services (DHHS) (R.J. Reynolds Tobacco Company, 2000b) Most of these ingredients are commonly used in foods and beverages, or permitted for use in foods by the U.S. Food and Drug Administration (FDA), or have been given the status “Generally Recognized as Safe in Foods” (GRAS) by FDA, the Flavor and Extract Manufacturers Association (FEMA) or other expert committees.
And from the Pierce study:
Diacetyl and 2,3-pentanedione exposures associated with cigarette smoking: implications for risk assessment of food and flavoring workers. - PubMed - NCBI
Diacetyl and 2,3-pentanedione inhalation have been suggested as causes of severe respiratory disease, including bronchiolitis obliterans, in food/flavoring manufacturing workers.
Both compounds are present in many food items, tobacco, and other consumer products, but estimates of exposures associated with the use of these goods are scant.

It is the
formaldehyde, not diacetyl, that is a result of combustion of tobacco or from extreme (unreal) conditions in heating eliquid. As Dr. F pointed out.
