A man's exposure to second-hand smoke during childhood may increase his children's risk of developing chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, according to research published in the journal Thorax. Although this is an observational study from which no firm conclusions about causality can be drawn, the authors believe that their findings could be due, at least in part, to a type of epigenetic inheritance and ‘suggest that smoking may adversely affect lung function not only in smokers, but also in their children and grandchildren.’

A team from the United Kingdom has conducted an umbrella review, or review of reviews, on the risks of vaping among young people. After analysing 56 reviews including 384 studies, their conclusions are that vaping is subsequently associated with increased consumption of tobacco, marijuana and alcohol. It is also associated with an increased risk of asthma, coughing, injuries and mental health problems. The results are published in the journal Tobacco Control.

Coinciding with the World Conference on Tobacco Control - to be held June 23-25 in Dublin, Ireland - the World Health Organization (WHO) is releasing its report on the global tobacco epidemic, responsible for more than seven million deaths worldwide each year. The WHO warns that "action is needed to maintain and accelerate progress in tobacco control, as increasing industry interference calls into question tobacco control policies and efforts.

In a group of people at high cardiovascular risk, low to moderate wine consumption was associated with fewer cardiovascular events (cardiovascular death, myocardial infarction, stroke or heart failure), according to a study. The analysis uses urinary concentrations of tartaric acid, a substance found in grapes and grape derivatives, as a biomarker of wine consumption. It finds that consuming between three and 35 glasses per month was associated with fewer cardiovascular events than in people who consumed fewer than three or more than 35 glasses. The study, published in the European Heart Journal, included more than 1,200 participants from Spain's PREDIMED study with an average age of 68 years.

An international team with Spanish participation has analysed which day of the week has the highest risk of suicide mortality, and it is Monday. The research, published in The BMJ, includes more than 1,700,000 suicide cases registered in 26 countries - including Spain - from 1971 to 2019. The data also show a sharp increase in the risk of suicide on New Year's Day in most of the countries analysed. Taking these results into account, the authors propose that they should be used to define plans and awareness-raising campaigns.

If lifetime tobacco consumption were banned among young people currently aged 14 to 18, 1,200,000 lung cancer deaths worldwide could be prevented in the future, according to a study with Spanish involvement published in the journal The Lancet Public Health. The greatest impact would occur in low- and middle-income countries, but in higher-income regions, more than 60% of lung cancer deaths in that age group would also be avoided.

Ahead of World Suicide Prevention Day on September 10, a new series of six articles published in The Lancet Public Health calls for a shift in the narrative. Experts advocate for moving beyond framing suicide solely as a mental health issue, emphasizing the need to recognize the impact of social factors such as poverty, debt, addiction, homelessness, abuse, discrimination, and social isolation.

A clinical trial in Finland has compared the effectiveness of nicotine-containing e-cigarettes and varenicline tablets for smoking cessation. The study, which included 458 participants, found no difference between the two strategies at six months. However, after one year, only varenicline was found to be clearly more effective than placebo. The results are published in the journal JAMA Internal Medicine.  

A journalistic investigation by The Investigative Desk (Netherlands) and The BMJ (UK) concludes that tobacco industry-funded studies continue to appear in the most cited medical journals. The team of journalists found hundreds of links in the PubMed database between the medical and pharmaceutical subsidiaries of the big tobacco companies - Philip Morris International, Altria, British American Tobacco, Imperial Brands and Japan Tobacco International - and published medical research. In addition, the research revealed that of 40 journals - the 10 most cited in general medicine and another 30 in areas affected by smoking - only eight had policies prohibiting studies funded in whole or in part by the tobacco industry. 

E-cigarettes, vapes, pods, mods... The popularity of these devices continues to grow, especially among young people. According to a Spanish survey, more than half of the adolescents aged 14 to 18 have used them at some point. Vaping control varies from country to country: in Spain, vaping products have been regulated since 2017 and the new anti-smoking plan aims to equate their legislation to that of tobacco, while the United States imposes fewer restrictions. In this brief guide, we explain what is known and not known on controversial issues such as the safety of electronic cigarettes, their risks or whether they are useful to quit tobacco.
