The principal objective of this study was to determine whether drugs and crime are systemically linked through the formation of delinquent peer associations. A panel of 1,760 adolescents (867 boys, 893 girls, ages 10-17) participated in a longitudinal study conducted over 4 waves, with a year between each wave. The results of a multiple serial causal mediation path analysis revealed that drug use at Wave 1 predicted a rise in delinquent peer associations at Wave 2, which, in turn, predicted an increase in proactive criminal thinking and personal victimization at Wave 3, both of which then proceeded to predict serious offending at Wave 4. Based on these results, it is concluded that drug use has the power to initiate and intensify involvement in a delinquent peer group, which then opens the door to learning deviant attitudes from and being victimized by members of this group, outcomes capable of motivating future offending behavior.

解释毒品犯罪与同伴，主动犯罪思维和受害关系：系统的，认知的社会学习和人与人之间的联系机制。

这项研究的主要目的是确定毒品和犯罪是否通过犯罪同伴协会的建立而系统地联系在一起。一组1,760名青少年（男孩867名，女孩893名，年龄10-17岁）参加了一次纵向研究，历时4次，每次两次之间。多重系列因果中介路径分析的结果表明，第一波的毒品使用预测了第二波的不良同伴关系的增加，这反过来又预测了第三波的主动犯罪思维和个人受害人数的增加，这两者然后继续预测在第4浪中的严重违法行为。基于这些结果，可以得出结论，吸毒有能力启动和加剧参与犯罪的同龄人群体的活动，这就为从该小组成员中学习变态态度并受其所害打开了大门，这种结果能够激发未来的冒犯行为。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
