According to a team of scientists from the University of Rochester, vaping flavors such as vanilla and cinnamon are toxic to leukocytes, or white blood cells, increasing the risk of developing life-threatening diseases.
For the study, the researchers exposed immune cells to chemicals used in e-cigarette flavoring. They discovered that this type of cells produced substances responsible for inflammation and tissue damage. In addition, many of the flavoring chemicals caused a significant level of the death of these cells.
Senior author Dr. Irfan Rahman, of the environmental health sciences center, says: “While e-cigarettes are thought to have relatively less or no harm to the consumer’s health compared to tobacco smoke, vaping flavors are not safe for inhalation. Currently, these are not regulated, and alluring flavor names, such as candy, cake, cinnamon roll and mystery mix, attract young vapers.”
New research has confirmed that exercise can help smokers finally kick the habit.
Experts at St George’s University of London, have examined the mechanism that makes exercise to protect the body against nicotine dependence. The study has shown that even moderate intensity exercise can significatly reduce nicotine withdrawal symptoms.
Also researhes revealed the incrased activation of one of the receptors in brain named α7 nicotinic acetylcholine, which is a target of nicotine.
Dr Alexis Bailey, Senior Lecturer in Neuropharmacology, at St George’s, University of London, said: “The evidence suggests that exercise decreases nicotine withdrawal symptoms in humans; however, the mechanisms mediating this effect are unclear.
“Our research has shed light on how the protective effect of exercise against nicotine dependence actually works.”

A new research, published in the European Respiratory Journal, finds a diet rich in tomatoes may restore lung function in people who quit smoking and slow down lung function decline and all people.
In the course of the study, the scientists found that those adults who ate more than three portions of fruit or more than two tomatoes experience slower lung function decline than those who consumed fewer than one serving of fruit or one tomato a day.
The lead study author Vanessa Garcia-Larsen, an assistant professor in the Bloomberg School’s Department of International Health, says: “This study shows that diet might help repair lung damage in people who have stopped smoking. It also suggests that a diet rich in fruits can slow down the lung’s natural aging process even if you have never smoked.”
According to a new research, led by Daniel J. Conklin, Ph.D., an assistant professor at the University of Louisville, electronic cigarettes may affect heart rate and function.
For the study, the scientists exposed healthy mice to electronic nicotine delivery systems (ENDS) for 9 minutes. In addition, the mice were exposed to smoke from traditional cigarettes with and without nicotine.
Having analyzed the received results, the authors of the study concluded that ENDS aerosols strongly affect cardiovascular function in mice. Also, the study revealed that the mice also showed an increased blood pressure.
A new study led by Dr. Hui Chen from the University of Technology Sydney, Australia, suggests that smoking during pregnancy can be a risk factor for cerebral palsy in offspring.
A team of researchers achieved their results by studying mice born to mothers that had been exposed to cigarette smoke before and during pregnancy. In the course of the study, the scientists tested motor skills of the mouse pups and discovered that they demonstrated movement issues similar to those that arise in cerebral palsy.
Dr. Hui Chen says: “However, the message for the public is if you want a healthy baby, you need to stop smoking long before you plan for the pregnancy.”
