Study finds e-cigarettes affect airways, and quickly
A new study has shown that e-cigarettes have adverse short-term effects on lung function within the first five minutes of use. Healthy nonsmokers were asked to use e-cigarettes for five minutes, and then the researchers tested their lung function. When compared against a control group that used e-cigarettes with the cartridge removed, the experimental group of e-cigarette users showed signs of airway constriction and inflammation. Although research about the long-term effects is still needed, this study raises concerns about repeated use of e-cigarettes over time. Click here to read the study abstract published in Chest.

Tobacco industry studies on cigarette additives safety may be misleading
A recent study suggests that scientific research published by the tobacco industry is misleading and cannot be taken at face value. Researchers from the Center for Tobacco Control Research at the University of California, San Francisco (UCSF) analyzed the design and results of Project MIX, a study conducted by scientists from Philip Morris to determine the health effects of additives in cigarettes. It was found that the Philip Morris scientists had changed study protocol and results to show that additives in cigarettes did not increase toxicity. The UCSF researchers also found that the number of study subjects (sample size) in Project MIX may have been too small to detect real changes in toxicity. Using Project MIX’s original data, researchers from UCSF found that toxins in cigarettes substantially increase when additives, such as menthol, are put in cigarettes. The authors of this study suggest that regulatory authorities use Project MIX data to eliminate additives in cigarettes. Read more here and read the study abstract published in PLoS Medicine here.
