本研究旨在确定澳大利亚青少年使用大麻的不同发展轨迹（表现出类似纵向模式的个人亚组），并研究轨迹组成员资格与青年期社会和行为调整措施之间的关联。参与者（n= 852，53%女性）是国际青年发展研究的一部分。潜在类别增长分析用于确定平均年龄12至19岁的大麻使用频率的不同轨迹，跨越6波数据。使用逻辑回归分析和协方差分析来检查轨迹群体成员资格与年轻人（平均年龄：21岁）调整之间的关系，控制一系列协变量。确定了三种轨迹：戒酒者（62%），早发使用者（11%）和迟发偶尔使用者（27%）。早发性使用者表现出更高的频率的反社会行为，暴力，大麻使用，大麻相关的危害，香烟使用，酒精危害，相比，在年轻的成年禁欲组。与年轻成年期的禁欲组相比，晚发型偶尔使用者报告了更高频率的大麻使用，大麻相关危害，非法药物使用和酒精危害。轨迹组之间在就业、学业完成、中学后教育、收入、抑郁/焦虑或饮酒问题方面没有差异。总之，早期开始使用大麻，即使在青少年时期使用频率相对较低，也与青年期的适应能力较差有关。为延迟或防止吸食大麻而开展的预防和干预工作应特别侧重于12岁之前的青春期早期。
This study aimed to identify distinct developmental trajectories (sub-groups of individuals who showed similar longitudinal patterns) of cannabis use among Australian adolescents, and to examine associations between trajectory group membership and measures of social and behavioural adjustment in young adulthood. Participants (n= 852, 53% female) were part of the International Youth Development Study. Latent class growth analysis was used to identify distinct trajectories of cannabis use frequency from average ages 12 to 19, across 6 waves of data. Logistic regression analyses and analyses of covariance were used to examine relationships between trajectory group membership and young adult (average age: 21) adjustment, controlling for a range of covariates. Three trajectories were identified: abstainers (62%), early onset users (11%), and late onset occasional users (27%). The early onset users showed a higher frequency of antisocial behaviour, violence, cannabis use, cannabis-related harms, cigarette use, and alcohol harms, compared to the abstinent group in young adulthood. The late onset occasional users reported a higher frequency of cannabis use, cannabis-related harms, illicit drug use, and alcohol harms, compared to the abstinent group in young adulthood. There were no differences between the trajectory groups on measures of employment, school completion, post-secondary education, income, depression/anxiety, or alcohol use problems. In conclusion, early onset of cannabis use, even at relatively low frequency during adolescence, is associated with poorer adjustment in young adulthood. Prevention and intervention efforts to delay or prevent uptake of cannabis use should be particularly focussed on early adolescence prior to age 12.
