Studies have examined trends in cannabis vaping, but research is needed to examine trends in more frequent use as this may increase risk for adverse health outcomes.
Data were from 12,561 high school seniors participating in the Monitoring the Future national study. Prevalence of self-reported frequent vaping of cannabis (defined as using ≥10 times in the past month) was compared between 2018 and 2019 cohorts.
Frequent vaping of cannabis significantly increased from 2.1% to 4.9%, a 131.4% increase. This increase was larger than the increase for any vaping of cannabis (which increased 85.9%). Notable significant increases occurred among students aged ≥18 years (a 154.9% increase), female students (a 183.5% increase), those who go out 4-7 evenings per week (a 163.0% increase), and those reporting past-year nonmedical prescription opioid use (a 184.7% increase).
Frequent vaping of cannabis is increasing among adolescents in the United States, particularly among selected subgroups.
已有研究调查了大麻吸食的趋势，但需要研究更频繁吸食的趋势，因为这可能会增加不良健康后果的风险。
数据来自于参与“监测未来”全国研究的 12561 名高中生。比较了 2018 年和 2019 年队列中自我报告的大麻频繁吸食（定义为过去一个月内使用≥10 次）的流行率。
大麻的频繁吸食率从 2.1%显著上升至 4.9%，增长了 131.4%。这一增幅大于任何大麻吸食（增加 85.9%）的增幅。在≥18 岁的学生（增长 154.9%）、女学生（增长 183.5%）、每周外出 4-7 晚的学生（增长 163.0%）以及报告过去一年非医疗目的使用处方类阿片类药物的学生（增长 184.7%）中，显著的增幅更为显著。
美国青少年中频繁吸食大麻的现象正在增加，特别是在某些特定亚群中。
