Many people switch to e-smoking because they believe that
e-cigarettes could be safer than real cigarettes. Although some of the
information available seems to suggest that e-cigarettes actually could
be safer, it’s not a sure thing. One of the reasons is the sheer variety
of flavors used in e-liquids and the fact that few — if any — of those
flavors have been tested for safety when inhaled.
For example, it was found not too long ago that some e-liquids contained diacetyl.
Diacetyl is accepted as a safe substance to consume — it’s the
substance that allows low-fat microwave popcorn to taste buttery.
However, when inhaled in large quantities it can lead to irreversible
lung damage. Most e-liquid makers have taken steps to make sure their
products contain no diacetyl, but it serves as an example of why you
should always obtain as much information as possible about what your
e-liquid contains.
In addition, some e-liquids contain extracts of real tobacco. You may
see the term “tobacco absolute” used in conjunction with these types of
e-liquids. Tobacco absolute is a pure, thick extract that tastes bitter
and ashy. It can add greatly to the complexity and depth of an
e-liquid. It is unknown whether the use of a real tobacco extract makes
an e-liquid more dangerous to use.
