Alternative nicotine products like e-cigarettes could help achieve an end to the epidemic of ill health and death caused by smoking. However, in-depth information about their use is often limited. Our study investigated patterns of use of e-cigarettes and attitudes and beliefs among smokers and ex-smokers in New Zealand (NZ), a country with an 'endgame' goal for smoked tobacco. Data came from smokers and ex-smokers in Waves 1 and 2 of the International Tobacco Control (ITC) NZ Survey (Wave 1 August 2016-April 2017, 1155 participants; Wave 2, June-December 2018, 1020 participants). Trial, current and daily use of e-cigarettes was common: daily use was 7.9% among smokers and 22.6% among ex-smokers in Wave 2, and increased between surveys. Use was commonest among 18-24 years and ex-smokers, but was similar among Māori and non-Māori participants, and by socio-economic status. Most participants used e-cigarettes to help them quit or reduce their smoking. The most common motivating factor for use was cost and the most common barrier to use cited was that e-cigarettes were less satisfying than smoking. The findings could inform developing interventions in order to maximise the contribution of e-cigarettes to achieving an equitable smoke-free Aotearoa, and to minimise any potential adverse impacts.
替代尼古丁产品，如电子烟，可能有助于终结因吸烟导致的健康不良和死亡的流行。然而，关于它们的使用情况的深入信息通常是有限的。我们的研究调查了新西兰（NZ）吸烟者和戒烟者使用电子烟的模式以及他们的态度和信念，新西兰有一个针对传统烟草的“终结游戏”目标。数据来自国际烟草控制（ITC）NZ 调查的第 1 波和第 2 波的吸烟者和戒烟者（第 1 波，2016 年 8 月至 2017 年 4 月，1155 名参与者；第 2 波，2018 年 6 月至 12 月，1020 名参与者）。试用、当前和每日使用电子烟都很常见：第 2 波中，每日使用电子烟的吸烟者为 7.9%，戒烟者为 22.6%，且在两次调查之间有所增加。18-24 岁和戒烟者中使用电子烟最常见，但毛利人和非毛利人参与者之间以及社会经济地位之间的使用情况相似。大多数参与者使用电子烟是为了帮助他们戒烟或减少吸烟。使用电子烟的最常见动机是成本，而使用的最常见障碍是电子烟不如吸烟令人满意。这些发现可以为制定干预措施提供信息，以最大限度地发挥电子烟对实现公平的无烟 Aotearoa（新西兰的毛利语名称）的贡献，并尽量减少任何潜在的不利影响。
