RESUMO
BACKGROUND: Media reports of a vaping epidemic among youth have raised concerns about the creation of a new generation of nicotine-dependent individuals who could graduate to cigarette smoking. We investigated the use of e-cigarettes and cigarettes in the youth of New Zealand from 2014 to 2019, with focus on daily use of these products as an indicator of potential dependence. METHODS: We analysed data from the Action for Smokefree 2025 Year-10 survey, an annual cross-sectional survey of tobacco use undertaken by almost half of all school students aged 14-15 years (21â504-31â021 students). The survey includes questions on whether students had ever smoked (even just a few puffs) and their current smoking behaviour (at least once a day, week, or month, or less often than once a month). In 2014, a question was added asking if students had ever tried an e-cigarette. Subsequent surveys asked about e-cigarette use at least once a day, week, or month, or less often than once a month. We compared the frequency of e-cigarette use with cigarette smoking by survey year, age, gender, ethnicity, and school decile (a proxy for socioeconomic status). We did χ2 analyses to compare categorical variables and Cochran-Armitage trend tests to assess changes over time. Multiple logistic regression was used to determine predictors of e-cigarette and cigarette use in 2019. FINDINGS: All measures of e-cigarette use increased and all measures of cigarette use decreased or remained static over time. Although the proportion of students who had ever tried e-cigarettes in 2019 (37·3%, 10â093 of 27â083), exceeded the proportion who had ever smoked (19·6%, 5375 of 27â354), daily use of products was low: e-cigarettes (3·1%, 832 of 26â532), cigarettes (2·1%, 575 of 27â212), both (0·6%, 159 of 27â633). In 2019, daily use of e-cigarettes was very low in never-smokers (0·8%, 175 of 21â385). Students who were Maori, Pacific, gender diverse, or from low-decile and mid-decile schools were more likely to be daily users of e-cigarettes or cigarettes, and males were more likely to be daily e-cigarette users, but less likely to smoke daily than females. INTERPRETATION: The overall decline in smoking over the past 6 years in New Zealand youth suggests that e-cigarettes might be displacing smoking. Ongoing monitoring will be important to determine whether the liberalisation of e-cigarette availability and marketing in New Zealand has any effect on long-term patterns of daily e-cigarette and cigarette use.

Smoking is one of the biggest threats to public health, costing more than 120,000 lives per year in the UK alone (Peto et al, 2004). Helping smokers give up is one of the most effective health interventions and nurses are in a unique position to fill that role.

INTRODUCTION: Increasing excise tax on tobacco is one of the most powerful and cost-effective smoking interventions. Despite this evidence, there has been no substantial tax increase in New Zealand between 2000 and 2010. In April 2010 a 10% tax increase on factory-made cigarettes and a 24% tax increase on loose leaf tobacco was implemented. AIM: To evaluate the effect of cost as a motivating reason for smokers to make a quit attempt before and after the 2010 tobacco tax increase. METHODS: A regression analysis of a cross-sectional study was conducted. Data were collected from August to October 2009 and compared with data collected in July 2010. RESULTS: In 2009, 25.5% of smokers cited cost as a reason for trying to quit smoking compared with 55.6% in 2010. The adjusted odds of making a quit attempt with cost as a reason were 3.6 (95% CI 2.3-5.6, P = <0.001). Furthermore, smokers were more likely to make a quit attempt in 2010 than in 2009. Thirty percent of smokers made at least one quit attempt in 2009 and 39% made a quit attempt in 2010 (adjusted odds ratio 1.5, 95% CI 0.95-2.3, P = <0.1) DISCUSSION: The recent tax increase on tobacco in New Zealand has resulted in more smokers making an attempt to quit smoking and more smokers identifying cost as a motive for quitting.
