Berkeley Lab Confirms Thirdhand Smoke Causes DNA Damage

A study led by researchers from Lawrence Berkeley National Laboratory has found for the first time that thirdhand smoke—the noxious residue that clings to virtually all surfaces long after the secondhand smoke from a cigarette has cleared out—causes significant genetic damage in human cells.

Furthermore, the study also found that chronic exposure is worse than acute exposure, with the chemical compounds in samples exposed to chronic thirdhand smoke existing in higher concentrations and causing more DNA damage than samples exposed to acute thirdhand smoke, suggesting that the residue becomes more harmful over time.

Do peppers reduce risk of Parkinson’s?

Eating peppers — which are in the same botanical family as tobacco — may reduce the risk of Parkinson’s disease. The findings are reported in the May 9 edition of the Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society.

Nearly one million people in the United States are living with Parkinson’s disease, a neurodegenerative disorder that results from the loss of dopamine-producing brain cells. In early stages, Parkinson’s is characterized by difficulties in controlling movement. Initial symptoms include hand tremors, limb rigidity, and problems walking. As the disease progresses, cognitive problems may develop and advance into dementia. (more…)

Smokers with Mental Disorders, Drug and Alcohol Problems Need Doctors’ Help to Quit

Smokers who also have alcohol, drug and mental disorders would benefit greatly from smoking-cessation counseling from their primary care physicians and would be five times more successful at kicking the habit, a study by researchers at UCLA’s Jonsson Comprehensive Cancer Center has found.

Smokers with these co-morbid conditions make up about 40 percent of the smoking population, have a more difficult time quitting and represent a significant burden on the health care system. If their primary care physicians could help them to quit smoking, it would not only improve their health of patients but would reduce tobacco-related health care costs, said Dr. Michael Ong, an assistant professor of general internal medicine and health services research at the David Geffen School of Medicine at UCLA and a researcher with UCLA’s Jonsson Comprehensive Cancer Center.

Nicotine May Play Key Role in Promising Alzheimer’s Therapy

COLLEGE PARK, Md. — A team of neuroscientists has discovered important new information in the search for an effective treatment for Alzheimer’s disease, the debilitating neurological disorder that afflicts more than 5.3 million Americans and is the sixth-leading cause of death in the United States. Hey-Kyoung Lee , associate professor in the University of Maryland Department of Biology, and her research team have shown that they may be able to eliminate debilitating side effects caused by a promising Alzheimer’s drug by stimulating the brain’s nicotine receptors.

Smoking Increases Depressive Symptoms in Teens

While some teenagers may puff on cigarettes to “self-medicate” against the blues, scientists at the University of Toronto and the University of Montreal have found that smoking may actually increase depressive symptoms in some adolescents. Published in the journal Addictive Behaviors, the findings are part of the long-term Nicotine Dependence in Teens (NDIT) study based at the University of Montreal Hospital Research Centre.
