Teens are more likely to light up if their parents ever smoked – even before they were born – compared to children whose parents have always been non-smokers, according to a new study published in the journal Pediatrics. The research further revealed that having an older brother or sister who smoke also raises the odds that a teen will pick up the habit. “These findings imply that any amount of smoking could have important influences on the next generation,” said lead researcher Mike Vuolo from Purdue University in the United States. “Given the influence on the oldest siblings, this is especially the case in heavy-smoking households.” Vuolo and co-author, Jeremy Staff from Pennsylvania State University, analysed data from a multigenerational study that followed participants from 1988, when they just went to high school, through to 2011. The study looked at 214 participants who are now-parents, and 314 of their children

When smoking was banned from casinos in Colorado in the United States, ambulance calls to casinos in the area dropped about 20 percent, according to research reported in the American Heart Association journal Circulation. The drop in calls from casinos was similar to drops in ambulance calls from elsewhere two years earlier when Colorado banned smoking everywhere but casinos. How did the smoking ban lead to a reduction in ambulance calls? Partially by eliminating exposure to secondhand smoke, said Stanton Glantz, PhD, the study’s lead author. “Inhaling secondhand smoke increases the chances of blood clots than can block arteries and makes it more difficult for arteries to expand properly, changes that can trigger heart attacks,” said Glantz, director of the Centre for Tobacco Control Research and Education and professor of medicine in the division of cardiology at the University of California, San Francisco. “The calls may also have decreased due

Maternal smoking can cause the third generation of offspring to suffer from asthma, a new study by Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Centre found. The study, published online by the American Journal of Physiology – Lung Cellular and Molecular Physiology, reported that maternal nicotine exposure during pregnancy is linked to asthma in the third generation in disease models. This is known as a “transgenerational” linkage because the third generation was never directly exposed to nicotine or smoking. Previous research had found nicotine exposure was linked to asthma in the second generation, or was a “multigenerational” cause of asthma. “Even though there are multiple causes for childhood asthma, research linking this serious chronic condition to maternal nicotine exposure during pregnancy for up to three generations should give mothers-to-be even more reasons to reconsider smoking,” said Virender K. Rehan, lead researcher of the study. “Eliminating the use of tobacco
