What is "acetoin," and what is it doing in cigarettes? Tobacco companies inform the U.S. Department of Health and Human Services [3] (but not the public) about the 599 potential additives they can put in cigarettes. We've got that list [4], but we don't have any explanations about what these chemicals are. Acetoin is on the list, but we don't know what it is, or why they put it in cigarettes. Help us find out, so everyone can know: Go to Tobaccowiki [5], scroll down to "Tobacco Topics," click on "Additives," then on "acetoin"; click the Legacy Tobacco Documents Library search button. Browse through the documents you get back, and look for information about acetoin. Add the information you find to the TobaccoWiki article on acetoin.
