Certain product characteristics, such as flavor, may increase adolescents' willingness to try vaped nicotine and cannabis (marijuana) products.
A discrete choice experiment embedded within the 2021-2022 California Teens Nicotine and Tobacco Project Online Survey was administered to a non-probability sample of N = 2342 adolescents ages 12-17. Participants were sequentially presented four randomly-generated pairs of hypothetical vape products that varied in device type (disposable, refillable), content (nicotine, marijuana, "just vapor"), and flavor (seven options) and asked which of these (or neither) they would be more willing to try if a best friend offered. Conditional logistic regression quantified associations between product characteristics and participants' selections, including interactions by past 30-day use of e-cigarettes, marijuana, or both.
Candy/dessert, fruit, and fruit-ice combination flavors were all associated with greater willingness to try a vape product (versus tobacco flavor) among participants not using e-cigarettes or marijuana, those using only e-cigarettes, and those co-using e-cigarettes and marijuana. Among participants only using marijuana, the most preferred flavors were no flavor, candy/dessert, and icy/frost/menthol. Among participants not using e-cigarettes or marijuana, model-predicted willingness to try a displayed vape product was greater when products were sweet or fruit flavored than tobacco or unflavored, regardless of whether displayed options contained nicotine (fruit/sweet: 21 %, tobacco/unflavored: 4 %), marijuana (fruit/sweet: 18 %, tobacco/unflavored: 6 %), or "just vapor" (fruit/sweet: 29 %, tobacco/unflavored: 16 %).
In this online non-probability sample, flavors in nicotine and cannabis vape products increased adolescents' willingness to try them. Comprehensive bans on flavored vapes would likely reduce adolescent use.
某些产品特性，如口味，可能会增加青少年尝试电子烟和大麻（大麻）产品的意愿。
在 2021-2022 年加利福尼亚青少年尼古丁和烟草项目在线调查中嵌入了一项离散选择实验，该实验针对的是一个非概率样本，共有 N=2342 名年龄在 12-17 岁的青少年。参与者依次呈现四对随机生成的假设电子烟产品，这些产品在设备类型（一次性、可再填充）、内容（尼古丁、大麻、“仅蒸汽”）和口味（七种选择）上有所不同，并被问到如果一个最好的朋友提供了这些产品中的哪一种（或两者都不提供），他们会更愿意尝试哪一种。条件逻辑回归量化了产品特征与参与者选择之间的关联，包括过去 30 天使用电子烟、大麻或两者的交互作用。
在未使用电子烟或大麻、仅使用电子烟或同时使用电子烟和大麻的参与者中，糖果/甜点、水果和水果冰沙混合口味都与尝试电子烟产品的意愿增加有关（与烟草口味相比）。在仅使用大麻的参与者中，最受欢迎的口味是无口味、糖果/甜点和冰冷/冰霜/薄荷。在未使用电子烟或大麻的参与者中，无论显示的选项是否含有尼古丁（水果/甜：21%，烟草/无味：4%）、大麻（水果/甜：18%，烟草/无味：6%）或“仅蒸汽”（水果/甜：29%，烟草/无味：16%），与烟草或无味相比，甜味或水果味的电子烟产品更能提高参与者尝试显示产品的意愿。
在这项在线非概率样本中，尼古丁和大麻电子烟产品的口味增加了青少年尝试的意愿。全面禁止调味电子烟可能会减少青少年的使用。
