Are E-cigarettes Effective for Smoking Cessation?

Friday, May 22nd, 2015


A new study presented at the 2015 American Thoracic  Society International Conference concluded that there is little evidence that electronic cigarettes are effective for long-term smoking cessation. Researchers said “While e-cigarettes have been shown to significantly improve abstinence at 1 month compared with placebo, no such evidence is available supporting their effectiveness for longer periods.” “Until such data are available, there are a number of other smoking cessation aids available that have a more robust evidence base supporting their efficacy and safety.”

These conclusions were based upon a mega analysis of four studies of the efficacy and safety of e-cigarettes for promoting smoking cessation in 1011 patients and an additional 18 studies of the safety of e-cigarettes reporting adverse effects that occurred in 1212 patients.  At 1 month as previously noted, e-cigarettes significantly improved the prevalence of abstinence among study subjects, but this effect was absent at 3 and 6 month follow ups. Adverse effects of e-cigarettes noted included dry cough, throat irritation, and shortness of breath,. The researchers concluded “Although e-cigarettes are widely promoted and used as a smoking cessation tool, we found no data supporting their long term efficacy and safety.” “Given the potential health risks of using these unproven and unregulated devices, individuals seeking help with smoking cessation should consider other more well-established options until more research is performed.”

Are e cigarettes harmful

Research published in the RTI Press concluded that e cigarette harmful emissions contain enough nicotine, and numerous other chemicals to cause concern to smokers and non-smokers. A non-user, may be exposed to secondhand aerosol particles similar in size to tobacco smoke and diesel engine smoke.  In addition, E-products are not regulated and the chemicals and devices involved vary widely and so may the potential harmful impact to users and non-users. Thus, the need to explore the composition of e-cigarette vapor and the potential health impact of  secondhand exposure  Researchers said “We need to be aggressively investing in and conducting research that answers lingering questions about the potential health impact of secondhand exposure to e-cigarettes, while taking the necessary action to protect public health now.”

Are E-Cigarettes Safe for the Lungs?

Wednesday, February 18th, 2015


A new study published in the journal PLOS ONE concluded that emissions from e-cigarette aerosols and flavorings damage lung cells by creating harmful free radicals and inflammation in lung tissue indicating that they may be a toxic replacement for tobacco. .They also found that some flavored e-juices, especially cinammon, creates more stress and toxicity on lung tissue.

Researchers found that harm begins when the e-cigarette’s heating element is activated and turns a liquid solution into an aerosol that mimics cigarette smoke. The inhaled vapor contains heavy metals and other possible carcinogens in the form of nanoparticles that can reach further into the lungs. cells and blood stream. They observed that human lungs exposed to e-cigarette aerosols release various inflammatory biomarkers and mice exposed to e-cigarettes demonstrate signs of pulmonary inflammation. The researcher stated “Our research affirms that e-cigarettes may pose significant health risks and should be investigated further. It seems that every day a new e-cigarette product is launched without knowing the harmful effect of these products.”
