Men will live as long as women by 2032 because far fewer men are now smoking
According to a new report, “Inequalities Matter”, published this week, life expectancy will be the same for both sexes within 15 years. Experts said the biggest reason for the narrowing of the life expectancy gap is the changing levels of smoking between the sexes as cigarettes account for about 100,000 deaths a year in the UK from cancer and heart disease.
Professor Les Mayhew, a statistics expert at Cass Business School, who conducted the research for the report said: “This will be the first time that men will achieve parity with women since records began in 1841.”

USA: Study shows facial structure of mice embryos changed after exposure to e-cigarette vapor
Research conducted by Virginia Commonwealth University found that flavoured e-cigarettes caused facial abnormalities in mice embryos. They exposed female mice to 10 puffs of aerosol, using four different variations of the liquid: two each of unflavored and ‘nut’ flavoured and one of each flavour had nicotine while the other was nicotine-free.
When they bred those mice, they found that they carried fewer embryos than did the group of female mice that were not exposed to vapor. As those embryos which had been exposed developed, researchers made 3D recreations of their facial structures by referencing important markers on CT scans of the unborn mice. The areas around the embryonic mice’s faces were developing to be shorter and more narrow than they typically would be, regardless of whether or not the e-liquid used was flavored. Mice whose mothers had been exposed to the nut flavored e-cigarette vapor showed further signs of abnormality to their mouths, jaws and cheek areas.
Editorial note: In the past studies using mice showed harms from exposure to nicotine to embryos. However, the same effects have not been found in humans when using NRT in the real world. As such findings from studies using mice should be treated with caution.

USA: FDA to re-examine premium cigars as it overhauls tobacco regulation
The Food and Drug Administration is taking another look at premium cigars in a move that anti-tobacco groups fear could weaken regulations.
It is seeking guidance on how it should regulate premium cigars. It expanded the definition of tobacco products in 2016 and in doing so, brought premium cigars within its oversight. In its advance notice of proposed rulemaking published Friday, the FDA says it’s seeking feedback on how to define premium cigars, how these products are used and any public health considerations.
Robin Koval, the head of the Truth Initiative, called re-examining premium cigar regulation “a huge step backwards and a waste of time.” Campaign for Tobacco-Free Kids President Matthew Myers urged the FDA not to revise the rule that allowed the agency to regulate premium cigars and other tobacco products. “There is no public health justification for exempting any tobacco product from FDA oversight,” Myers said in a statement. “Instead, the FDA should move forward with several critical actions to accelerate progress in reducing tobacco use.”

USA: Smokers who vape are half as likely to ditch tobacco as those who never use e-cigarettes, study finds
Smokers who vape are half as likely to ditch tobacco as those who never use e-cigarettes, a study from the University of California San Francisco suggests. Those who just occasionally vape are 67% less likely to ditch smoking for good.
The researchers analysed the results of a 2014 survey that assessed smokers and ex-smokers in the EU. Of the 13,000 participants, who had an average age of 50, 2,500 had tried vaping at least once. However, the study did not ask participants if they were planning to quit or cut down on their tobacco use, or if ex-smokers ditched the habit before e-cigarettes were widely available.
Editorial note: The study was not able to distinguish when people quit smoking. As such the sample will have included people who quit before e-cigarettes were widely available which could influence the reliability of these findings. The results of controlled trials and real-world studies such as the Smoking Toolkit Study conducted by UCL, find that e-cigarettes are associated with improved odds of quitting smoking and are not associated with decreased odds of quitting smoking.

Canada: Smoking in patients with heart attack reduced with varenicline
Researchers from Canada looked at the efficacy of varenicline in patients with acute coronary syndrome to determine whether it would increase smoking abstinence.
In patients who have had a heart attack, the drug varenicline significantly increased smoking cessation during the following year, according to a randomized controlled trial published in Canadian Medical Association Journal. Patients received smoking cessation counselling as well as either varenicline or a placebo control for 12 weeks. Most participants had moderate to severe nicotine dependency.
About 40% of participants who received varenicline were not smoking at one year, compared with 29% in the placebo group.
