Menthol has been hypothesized to ease the harshness of cigarette smoke. Thus, sensory experiences at first cigarette use may be one mechanism by which menthol facilitates progression to regular smoking. This study examined differences in subjective experiences to the first use of a menthol versus nonmenthol cigarette among new young adult smokers.
Data were drawn from waves 5-8 of the Truth Initiative Young Adult Cohort Study, a national sample of 18-34 year olds assessed every 6 months. Analyses included a subset of young adult current smokers (n = 251) who initiated smoking in the past 6 months. Subjective responses to first cigarette use were assessed across menthol and nonmenthol initiators in bivariate analyses and adjusted models controlling for smoking correlates.
Fifty-two percent of new young adult smokers used a menthol cigarette at first use. First use of a menthol cigarette was higher in those aged 18-24 (vs. 25-34). Most black smokers (93.1%) were menthol initiators compared to 43.9% of white smokers. More than half of menthol and nonmenthol initiates felt relaxed or calm, dizzy, lightheaded, liking the taste and a rush or buzz at first use. Menthol initiators were less likely in bivariate and multivariable analyses to experience feeling nauseated at first use (adjusted odds ratio = 0.45; p = .020) compared to nonmenthol initiators.
While few differences were found between menthol and nonmenthol initiators in their subjective experiences, fewer menthol initiates felt nauseated at first cigarette use. Future research needs to identify additional mechanisms linking menthol initiation to smoking progression.
Menthol initiators were more likely to be younger (18-24 vs. 25-34), and black (vs. white) compared to nonmenthol initiators. Our finding that menthol initiators were less likely to feel nauseated at first cigarette use compared to nonmenthol initiators suggests that menthol may reduce aversion to early cigarette use among young smokers and thus has the potential to facilitate continued experimentation. Interventions and policy approaches to reduce tobacco use initiation and progression are urgently needed in young people.
薄荷醇被认为可以减轻香烟烟雾的刺激性。因此,初次吸烟时的感官体验可能是薄荷醇促进人们转向常规吸烟的一个机制。本研究旨在探讨新成年吸烟者在初次使用薄荷醇与非薄荷醇香烟时的主观体验差异。
数据来自Truth Initiative 青年队列研究的第 5-8 波,这是一项针对 18-34 岁成年人的全国性样本,每 6 个月评估一次。分析包括最近 6 个月开始吸烟的青年成年当前吸烟者亚组(n=251)。在双变量分析和控制吸烟相关因素的调整模型中,评估了初次使用薄荷醇和非薄荷醇香烟时的主观反应。
52%的新成年吸烟者初次使用薄荷醇香烟。与 25-34 岁相比,18-24 岁的初次吸烟者使用薄荷醇香烟的比例更高。大多数黑人吸烟者(93.1%)是薄荷醇的初始使用者,而白人吸烟者的比例为 43.9%。超过一半的薄荷醇和非薄荷醇初始使用者在初次使用时感到放松或平静、头晕、头晕、喜欢味道和冲动或嗡嗡声。在双变量和多变量分析中,薄荷醇初始使用者初次使用时感到恶心的可能性较小(调整后的优势比=0.45;p=0.020),而非薄荷醇初始使用者则较少。
虽然在初次吸烟时的主观体验方面,薄荷醇和非薄荷醇初始使用者之间几乎没有差异,但薄荷醇初始使用者初次吸烟时感到恶心的比例较低。未来的研究需要确定将薄荷醇初始使用与吸烟进展联系起来的其他机制。
与非薄荷醇初始使用者相比,薄荷醇初始使用者更年轻(18-24 岁与 25-34 岁),而且更有可能是黑人(与白人相比)。我们发现,与非薄荷醇初始使用者相比,薄荷醇初始使用者初次吸烟时感到恶心的可能性较低,这表明薄荷醇可能会减少年轻人对早期吸烟的反感,从而有可能促进他们继续尝试吸烟。急需采取干预措施和政策方法,减少年轻人的烟草使用初始和进展。
