E-cigarettes are available in a variety of flavors not found in traditional tobacco products (i.e., "nontraditional flavors"), which is a commonly-cited reason for e-cigarette use. This review examines the prevalence of nontraditional-flavored e-cigarette use, mechanisms through which flavorings enhance product appeal, use of nontraditional-flavored e-cigarettes for smoking cessation, and differences in these findings between youth and adults.
Nontraditional-flavored e-cigarettes are used at e-cigarette initiation by the majority of youth. These flavors enhance the appeal of e-cigarettes by creating sensory perceptions of sweetness and coolness and masking the aversive taste of nicotine. Use of nontraditional-flavored e-cigarettes is higher among youth and young adults (vs. older adults) and among nonsmokers (vs. combustible cigarette smokers).
Nontraditional-flavored e-cigarettes are popular among youth, but may be less common among older adults and combustible cigarette smokers. Further research is needed to determine whether use of e-cigarettes in nontraditional flavors affects smoking cessation.
电子烟有多种传统烟草产品中没有的口味（即“非传统口味”），这是人们使用电子烟的一个常见原因。本综述探讨了使用非传统口味电子烟的流行情况、调味剂增强产品吸引力的机制、使用非传统口味电子烟戒烟的情况以及青少年和成年人在这些研究结果上的差异。
大多数青少年开始使用电子烟时使用的是非传统口味的电子烟。这些口味通过产生甜味和清凉感的感官感知以及掩盖尼古丁的厌恶味道来增强电子烟的吸引力。青少年和年轻人（与老年人相比）以及非吸烟者（与可燃香烟吸烟者相比）使用非传统口味电子烟的比例更高。
非传统口味的电子烟在青少年中很受欢迎，但在老年人和可燃香烟吸烟者中可能不太常见。需要进一步研究以确定使用非传统口味的电子烟是否会影响戒烟。
