To describe trends in cannabis use from 2010 to 2019 among Norwegian adolescents and relate these to individual- and municipal-level variables. Data from nationwide repeated cross-sectional surveys collected in 2010-2013 (T1), 2014-2016 (T2), and 2017-2019 (T3) were used to describe secular trends in proportions of adolescent cannabis use. Cross-sectional surveys in 410 of the total 428 municipalities of Norway. A total of 628,678 survey responses from adolescents aged ~13-19 years of age, in which 566,912 survey responses were eligible for analyses, representing data from 340 municipalities. Respondent's past year cannabis use, time, gender, school grade, municipality, geographical location, and municipality population. Boys reported overall higher cannabis use, with ~2:1 gender ratio for any past year cannabis use and a 3:1 gender ratio for frequent cannabis use. Adolescents in Eastern Norway reported higher cannabis use compared with other areas in the country, and adolescents from municipalities with a higher population size reported higher rates of cannabis use than smaller municipalities. A gradual increase in cannabis use from T1 to T3 was found in Eastern Norway and in the largest municipalities. More generally, proportions of past year cannabis use showed a marked increase from T2 to T3 across genders, grade/age groups, geographical location, and municipality population, with few exceptions. Our findings indicate that proportions of past year cannabis use have increased among Norwegian adolescents in recent years. Preventive interventions to hinder initiation of cannabis use, as well as measures to address frequent cannabis use among Norwegian adolescents, are needed.
描述2010年至2019年挪威青少年大麻使用趋势，并将这些趋势与个人和市政层面的变量相关联。使用2010 - 2013年（T1）、2014 - 2016年（T2）和2017 - 2019年（T3）全国重复横断面调查的数据来描述青少年大麻使用比例的长期趋势。对挪威428个市政当局中的410个进行横断面调查。共收到约13 - 19岁青少年的628,678份调查回复，其中566,912份回复符合分析条件，代表来自340个市政当局的数据。调查对象过去一年的大麻使用情况、时间、性别、年级、市政当局、地理位置和市政当局人口。男孩报告的大麻总体使用率较高，过去一年任何大麻使用的性别比约为2:1，频繁使用大麻的性别比为3:1。与该国其他地区相比，挪威东部的青少年大麻使用率更高，人口规模较大的市政当局的青少年大麻使用率高于较小的市政当局。在挪威东部和最大的市政当局中发现从T1到T3大麻使用逐渐增加。更普遍地说，过去一年大麻使用比例在T2到T3期间在各性别、年级/年龄组、地理位置和市政当局人口中均有显著增加，少数情况除外。我们的研究结果表明，近年来挪威青少年过去一年大麻使用比例有所增加。需要采取预防性干预措施来阻碍大麻使用的开始，以及采取措施解决挪威青少年频繁使用大麻的问题。
