    Recent claims by Otago University in New Zealand that vaping is a gateway to smoking have been disputed by leading global harm reduction experts Roberto Sussman, Konstantinos Farsalinos and Gerry Stimson. These experts have highlighted the importance of harm reduction strategies in reducing the negative health impacts of smoking.

    Published on June 28 in Drug and Alcohol Review, the Otago University study analyzed data related to New Zealanders’ smoking and vaping status from the 2018-2020 New Zealand Attitudes and Values survey.

    Unlike other studies, Post-graduate student Andre Mason and associate professor Damian Scarf found no consistent evidence that vaping acted as a cessation pathway from smoking. Mason said vaping appeared to be another smoking-related behavior, rather than a substitute for smoking that primarily helped people quit.

    “We found that there was an equal likelihood of vapers transitioning to smoking as smokers were to vapers,” Mason told Radio New Zealand.  

    Tobacco harm reduction advocates questioned the findings. According to Sussman, there is no evidence that vaping is a gateway to smoking. “In fact, studies have shown that vaping can be an effective tool for smoking cessation,” he said. “The vast majority of vapers are former smokers who have successfully quit smoking thanks to vaping,” added Farsalinos

    Gerry Stimson, a public health expert and advocate for harm reduction, emphasizes that harm reduction strategies like vaping are essential in reducing the negative health impacts of smoking. “We need to focus on providing smokers with safer alternatives to cigarettes, rather than demonizing harm reduction strategies like vaping,” he noted.

    Nancy Loucas, executive coordinator of the Coalition of Asia Pacific Tobacco Harm Reduction Advocates, who compiled these comments, also disputed the gateway claim by Otago University.

    Lous cited recent data, which suggest the smoking incidence rates in New Zealand have fallen significantly over the past five to 10 years. The current smoking rate of New Zealand adults is 8 percent in 2021/2022, which has decreased from 16.5 percent in 2015 and from 27 percent in both men and women in 1993. Loucas insists that vaping has played a significant role in the reduction of smoking rates in New Zealand over the past five to 10 years. According to research published in the NZ Medical Journal, the current vaping rate in New Zealand is 8.3 percent of adults being categorized as daily e-cigarette users, up from 6.2 percent in the previous year.

    “We need to focus on harm reduction strategies that work, rather than relying on outdated and inaccurate claims about vaping being a gateway to smoking,” said Loucas. “The evidence is clear: vaping can be an effective tool for smoking cessation and harm reduction.

    The government of New Zealand has given NZD1.4 million ($860,411) to a large trial to help New Zealanders quit vaping. Over six months, more than 1,000 participants will test whether cytisine—a medicine that partially blocks the effects of nicotine on the brain—is more effective than a tapered reduction in nicotine, when accompanied with behavioral support.

    A new study concludes that 18 to 24 year old’s that use e-cigarettes did not use vaping as a gateway to smoking combustible cigarettes.

    The report, published in the journal Addiction, examined e-cigarette use in England among young adults between 2007 and 2018, according to the Belfast Telegraph.

    In the study, a team from University College London reviewed data for England from the Smoking Toolkit Study.

    Lead author, Emma Beard, said the “findings suggest that the large gateway effects reported in previous studies can be ruled out, particularly among those aged 18 to 24.

    “However, we cannot rule out a smaller gateway effect and we did not study younger age groups.” she said.

    “If the upper estimates are true, we would estimate that of the 74,000 e-cigarette users aged 16 to 17 in England, around 7,000 would become ever regular smokers as a consequence of e-cigarette use.

    “At the same time, approximately 50,000 smokers are estimated to quit per year as a consequence of e-cigarette use.”

    Adolescent cigarette smoking has declined over the past several decades, e-cigarette use presents a new risk for nicotine use disorder, according to a new study. Published Nov. 9 in the journal Pediatrics, the new research suggests that e-cigarette use is associated with a higher risk of cigarette smoking among adolescents who had no prior intention of taking up conventional smoking.CosmicFog Lab-1

    “Research is showing us that adolescent e-cigarette users who progress to cigarette smoking are not simply those who would have ended up smoking cigarette anyway,” says Olusegun Owotomo, M.D., Ph.D., M.P.H., the study’s lead author and a pediatric resident at Children’s National Hospital in Washington, DC. “Our study shows that e-cigarettes can predispose adolescents to cigarette smoking, even when they have no prior intentions to do so.”

    The study uses data collected by the Population Assessment of Tobacco and Health (PATH) study, an NIH and FDA collaborative nationally representative prospective cohort study of tobacco use, from 2014-2016. A more recent PATH study has shown the rate of youth e-cigarette use is declining.

    Among adolescents who did not intend to smoke cigarettes in the future, those who used e-cigarettes were more than four times more likely to start smoking cigarettes one year later compared to those who did not use e-cigarettes.
