The Global Youth Tobacco Survey found nearly 9% of students aged 13-15 were current smokers, with high exposure to secondhand smoke and non-cigarette tobacco use among young girls. Reduction efforts require preventing initiation and promoting cessation, with strong smoke-free policies necessary to combat the growing toll of tobacco use.
A Mexican study found that indoor air pollution from wood smoke increases the risk of COPD, a lung disease. Women in developing countries are disproportionately affected due to their early exposure to biomass smoke.

A new study found that childhood exposure to second-hand smoke increases the risk of chronic dry cough and other respiratory problems in adulthood. Researchers discovered that consuming a small amount of fruit fiber, equivalent to eating two apples daily, can help mitigate these effects.
A Canadian Medical Association Journal study found that salivary cotinine levels, a measure of second-hand smoke exposure, are linked to an increased likelihood of smoking in adolescence. The research suggests that early childhood exposure may be a key factor in the development of nicotine-seeking behavior.
A study published in BMC Pediatrics finds that active maternal smoking, passive exposure, and even quitting during pregnancy can cause genetic damage in the developing fetus. This damage may have lifelong repercussions for the exposed fetus, affecting survival, birth weight, and susceptibility to disease.
A study by Christine Gieseke and Prue Talbot found that cigarette smoke significantly reduces the transport of hamster eggs through the oviduct.

The analysis highlights the troubling implications for world health as tobacco companies seek to increase smoking among women in developing countries.
A study of 225 women undergoing IVF found that side-stream smoking was associated with lower implantation and pregnancy rates compared to non-smoking and mainstream smoking groups. The researchers are calling for women to reduce or prevent exposure to cigarette smoke, especially when trying to conceive.
Alcohol consumption and cigarette smoke both impair lung defenses against Streptococcus pneumoniae, a bacterium that causes pneumonia and other infections. Researchers exposed rats to smoke and varying levels of alcohol, then infected them with S. pneumoniae, finding that the combination increased bacterial penetration into the lungs.
A new screening tool has been developed to assess children's exposure to secondhand smoke by asking caregivers about smoking factors in the home. The tool, which correlates with hair cotinine levels, can help pediatricians identify high-risk children and facilitate assessment in busy practices.
A three-question model asks about parental smoking habits and home environment to gauge ETS exposure risk. The study used hair samples to measure cotinine levels, finding that parental reports often underestimated child exposure.
Research found that alcohol consumption increases smoking urge in light smokers, regardless of nicotine withdrawal symptoms. The desire to smoke while drinking is related to the amount of alcohol consumed during a drinking episode.
A study of 316 internet websites found that most government and health advice sites incorrectly state the risks of smokeless tobacco as comparable to cigarettes. This misinformation may encourage smokers to stick with a much more hazardous product, despite available harm reduction options like switching to smokeless tobacco.
Researchers at NYU and MSKCC have discovered a conformational switch in DNA that changes the way carcinogens bind to p53 genes, potentially leading to cancer. The study sheds light on how environmental chemical carcinogens, including those found in cigarette smoke, can induce mutations and cancer.
A 2001 study commissioned by Philip Morris was cited in at least 19 papers, misleading physicians and researchers about the SIDS risk. The tobacco company paid scientists to challenge the scientific finding that secondhand smoke increases the risk of SIDS.
African American children with asthma have significantly higher levels of cotinine, a substance produced when the body breaks down nicotine. The study suggests that differences in additives to cigarettes, such as menthol, could explain the observed racial differences.
Researchers found that smoking promotes rapid production of COX-2 in oral mucosal cells, with tobacco smoke inducing EGFR activation. This activation leads to increased COX-2 protein production, highlighting a potential mechanism for tobacco-related cancers.
