Research on cannabis has focused on lifetime use or regular/heavy use (i.e., daily or almost daily). Regular, albeit not necessarily daily, cannabis use has received less scientific attention.
This study aims to identify demographic and personality factors associated with recurrent cannabis use (i.e., cannabis usage 5 to 50 times in the last six months) and to investigate the relationship between cannabis use and use of other substances.
Public and private university students ( = 11,236) in Bergen, Norway, participated in an online survey during autumn 2015. Binary logistic regression was run to identify individual characteristics related to recurrent cannabis use. Chi-square tests were conducted to investigate differences in substance use (alcohol, nicotine, and illicit drugs) between recurrent cannabis users and cannabis abstainers/low-frequency users.
A total of 4.0% of the students reported recurrent cannabis use. Students born in North America, non-Christians (compared to non-religious students), and men were more likely to be recurrent users. Recurrent cannabis users scored higher on extroversion and intellect/imagination compared to abstainers/low-frequency users. Male and female recurrent cannabis users had somewhat different characteristics (e.g., agreeableness scores were negatively associated with recurrent use among females but not among males). Recurrent cannabis use was overall strongly associated with polysubstance use.
The prevalence of recurrent cannabis use among Norwegian students is low. Recurrent cannabis use seems more prevalent among individuals marked by extroversion and intellect/imagination, which supports the notion of cannabis use as a social activity for individuals identifying themselves as outgoing and unconventional. Cannabis use among students seems strongly associated with use of other substances, suggesting that cannabis should not be considered a replacement drug.
对大麻的研究主要集中在终生使用或经常/大量使用（即每天或几乎每天使用）。定期（尽管不一定是每天）使用大麻受到的科学关注较少。
本研究旨在确定与反复使用大麻（即在过去六个月内使用大麻5至50次）相关的人口统计学和人格因素，并调查大麻使用与其他物质使用之间的关系。
2015年秋季，挪威卑尔根的公立和私立大学生（n = 11236）参与了一项在线调查。进行二元逻辑回归以确定与反复使用大麻相关的个体特征。进行卡方检验以调查反复使用大麻者与不使用/低频使用大麻者在物质使用（酒精、尼古丁和非法药物）方面的差异。
共有4.0%的学生报告反复使用大麻。出生于北美的学生、非基督徒（与无宗教信仰的学生相比）以及男性更有可能是反复使用者。与不使用/低频使用者相比，反复使用大麻的学生在外向性和智力/想象力方面得分更高。男性和女性反复使用大麻者有一些不同的特征（例如，宜人性得分在女性中与反复使用呈负相关，但在男性中并非如此）。反复使用大麻总体上与多种物质使用密切相关。
挪威学生中反复使用大麻的患病率较低。反复使用大麻似乎在外向性和智力/想象力特征明显的个体中更为普遍，这支持了将大麻使用视为那些将自己视为外向和非传统个体的社交活动的观点。学生中的大麻使用似乎与其他物质的使用密切相关，这表明大麻不应被视为替代药物。
