Adding Flavors to E-Cigarette Liquids Changes Chemistry, Creates Irritants


Our research was inspired by
the concern of the dramatic rise of use e-cigarettes,
specifically, by young people. And what’s known is that this is
driven by the large variety of flavors that the industry is
adding to these e-cigarettes. And based on our knowledge of
the chemistry of a lot of the favor chemicals in e-cigarates,
we were concerned that chemicals are formed in e-cigarates that
might be toxic to the users, and especially the young people who
are starting using them and become addicted to nicotine very quickly,
and use them chronically. And we indeed found that
the flavor chemicals in the liquids react with the solvents
that produce the vapor fumes that you see when
people vape these devices. And these new chemicals
are largely uncharacterized and we don’t know what their toxicity is. And in studies in cell systems we found,
indeed, that these compounds are irritating,
and over the long term may cause inflammation and
other effects in the user.
