In the United States (US), three in 10 cannabis users develop cannabis use disorder (CUD). Usage patterns in line with CUD may be associated with socio-economic disadvantage, and other negative effects. Thus, research on CUD is paramount. To provide understanding around CUD, it is necessary to detail granular cannabis usage preferences, as some risk from cannabis use may be mitigated through informed behavioral choices by users. We describe cannabis usage preferences among US Global Drug Survey (GDS) respondents, primarily young men. The cross-sectional web-based GDS (2017) was completed by 8345 US-resident respondents (median age = 23, Interquartile Range 19-32; % male = 75.48) who reported cannabis use. Of those who reported cannabis use in the past year, most (78%) reported consuming their first joint more than an hour after waking, and about half the sample (49%) had their last joint 1-2 h before bed. Cannabis was used for a median of 250 days in the last year (almost daily). Respondents spent a median of four hours a day stoned when cannabis was used. High potency herbal cannabis was the preferred variant by 62% of participants. We suggest that frequent use of cannabis may increase risk of health harms, and highlight the need to mitigate problematic use. With the rapidly developing US cannabis market, possibly problematic usage patterns may indicate potential for CUD especially within young men.
在美国，十分之三的大麻使用者会患上大麻使用障碍（CUD）。符合CUD的使用模式可能与社会经济劣势及其他负面影响有关。因此，对CUD的研究至关重要。为了深入了解CUD，有必要详细说明具体的大麻使用偏好，因为通过使用者明智的行为选择，大麻使用带来的一些风险可能会降低。我们描述了美国全球药物调查（GDS）受访者（主要是年轻男性）的大麻使用偏好。基于网络的横断面GDS（2017年）由8345名美国居民受访者（年龄中位数 = 23岁，四分位间距19 - 32岁；男性占比 = 75.48%）完成，这些受访者报告了大麻使用情况。在过去一年中报告使用过大麻的受访者中，大多数（78%）表示在醒来一个多小时后吸食第一口大麻，约一半的样本（49%）在睡前1 - 2小时吸食最后一口大麻。去年大麻使用天数的中位数为250天（几乎每天都用）。受访者在使用大麻时每天处于迷幻状态的时间中位数为4小时。62%的参与者更喜欢高效能草本大麻。我们认为频繁使用大麻可能会增加健康危害风险，并强调需要减轻有问题的使用行为。随着美国大麻市场的迅速发展，可能存在问题的使用模式可能表明尤其是年轻男性中存在CUD的可能性。
