GENEVA, Switzerland, Nov. 1, 2011 /CNW/ - In an article published today
in the European Respiratory Journal, results from a study on electronic cigarettes show users get as much
nicotine from this product as smokers usually get from tobacco
The study, by researchers from the Universities of Geneva and Auckland,
reports levels of cotinine (a product of the degradation of nicotine by
the liver) in users of electronic cigarettes.
This is the first time cotinine data among electronic cigarette users in
real-life conditions are published. So far, there were only laboratory
data among naïve users who used this product briefly before their blood
was tested for nicotine. These previously published data showed that
naïve users obtained little or no nicotine from electronic cigarettes.
The new research published today shows instead that experienced users
(all of them former smokers), in real life conditions (not in a
laboratory) get a dose of nicotine similar to the dose that smokers
usually get from tobacco cigarettes.
These results are important because governments in many countries are
developing regulations for electronic cigarettes (currently, some
countries prohibit them, others allow them with nicotine and others
without nicotine). In this context, it is very important to know, for
health authorities, doctors and consumers, that electronic cigarettes
can deliver as much nicotine as tobacco cigarettes.
