With the legalisation of cannabis products in Canada, there is a growing interest amongst youth in cannabis vaping products. This study aimed to explore the motivations behind the use of cannabis vaping products amongst youth and examine differences between frequent cannabis vapers and those who use other forms of cannabis. An online survey was conducted amongst youth aged 12–25 years. Descriptive statistics summarised responses separating youth who had frequently used (≥ weekly), occasionally used (< weekly to once per month), or did not use a cannabis vaping product in the past 12 months. A total of 1143 youth completed the study of which 830 (72.6%) had vaped cannabis in the past year, with most vaping cannabis oil (94.7%). Those who vaped weekly reported use of greater cannabis product diversity, higher tetrahydrocannabinol content, and increased spending compared to non-vapers. Vaping cannabis was perceived to be easier to conceal, had a faster onset of the high, and lacked odour in comparison to other cannabis products. Notably, 34.2% of youth who vaped considered flavour somewhat or very important in sustaining cannabis vaping use, with fruit flavours being the most popular. Youth from higher-income households and those using nicotine vaping devices were more likely to vape cannabis weekly (odds ratio: 1.83; 95% confidence intervals: 1.00–3.34 and 3.38, 1.99–5.73, respectively). Further research understanding why and how cannabis vaping products are used by youth is needed to understand potential harms associated with use as well as to create tailored education materials and messaging.

随着加拿大大麻产品的合法化，年轻人对大麻电子烟产品的兴趣日益浓厚。这项研究旨在探讨青少年使用大麻电子烟产品背后的动机，并研究经常使用大麻电子烟的人和使用其他形式大麻的人之间的差异。对 12 至 25 岁的青少年进行了一项在线调查。描述性统计数据总结了过去 12 个月内频繁使用（≥每周）、偶尔使用（<每周至每月一次）或未使用大麻电子烟产品的青少年的反应。共有 1143 名青少年完成了这项研究，其中 830 名青少年（72.6%）在过去一年吸过大麻，其中大多数吸食大麻油（94.7%）。那些每周吸电子烟的人报告称，与非电子烟使用者相比，他们使用的大麻产品更加多样化，四氢大麻酚含量更高，并且支出增加。与其他大麻产品相比，吸食大麻被认为更容易隐藏，产生快感的速度更快，而且没有气味。值得注意的是，34.2% 的吸电子烟青少年认为口味对于维持大麻电子烟的使用有一定程度或非常重要，其中水果口味最受欢迎。来自高收入家庭的青少年和使用尼古丁电子烟设备的青少年更有可能每周吸食大麻（比值比：1.83；95% 置信区间分别为：1.00–3.34 和 3.38、1.99–5.73）。需要进一步研究了解青少年使用大麻电子烟产品的原因和方式，以了解与使用相关的潜在危害，并创建量身定制的教育材料和信息。
