What drove these changes? Tobacco advertising (including for snus) has long been banned <br />in all three countries. Public health authorities speak out against all forms of tobacco, <br />including snus. Nonetheless, consumers, influenced by price and information from social <br />networks, have increased their use of snus. <br />So what has this to do with the emerging e-cigarette debate? <br />We’ve seen that snus is banned in most of Europe despite overwhelming evidence that it is <br />harm-reducing. And now e-cigs and other innovative ways of delivering nicotine without the <br />dangers created by burning tobacco face the same challenge. <br />Traditionalists demand more of the same policies that have significantly reduced tobacco <br />use: excise taxes, full implementation of smoke-free workplaces and more effective anti- <br />smoking advertising. Long-term projections say this would reduce smoking in the United <br />States from the current 20 per cent to 10 per cent by 2030. That’s welcome — but it still <br />leaves millions of smokers at risk. <br />The call for higher excise taxes ignores rising concerns about their regressive impact on <br />poorer and more-addicted smokers. It also ignores advances in the genetics of nicotine use, <br />suggesting that half of all smokers may not respond to tax increases because of their need <br />for nicotine. In other words, our one-size-fits-all approach to tobacco control is doomed to <br />fail. <br />Action on Smoking and Health estimates that 2.1 million British adults currently use e-cigs. <br />About one third are former smokers, and two thirds are still smokers. Meanwhile, regular <br />use of e-cigarettes by children and adolescents is confined almost entirely to current and <br />former smokers. Users claim that e-cigs help them stop smoking entirely (38 per cent) or <br />reduce the amount they smoke (25 per cent). Robert West, professor of health psychology at <br />University College London, reports that e-cig use by never-smokers is negligible and similar <br />to that of nicotine-replacement therapy (NRT). <br />In recent years, the increase in the popularity of e-cigs has more than offset a decrease in <br />NRT use. Successful attempts to quit smoking, although escalating, are still low, at between <br />5 and 7 per cent. E-cigs could play a major role in helping those smokers most addicted to <br />nicotine, who are shifting in increasing numbers from NRT products to ‘vaping’ as their <br />means of quitting the tobacco habit.
