This is the first study to assess the associations between the trajectories of marijuana use and other predictors of violent behavior with the use of guns or other weapons as well as stealing without the use of weapons among inner-city African Americans and Puerto Ricans (N = 838). Logistic regression analyses examined whether the longitudinal trajectories of marijuana use compared with the trajectory of no/low marijuana use predicted violent behavior. A higher Bayesian posterior probability (BPP) for the increasing marijuana use trajectory group (AOR = 3.37, P < .001), the moderate use of marijuana trajectory group (AOR = 1.98, P < .01), and the quitter trajectory group (AOR = 1.70, P < .05) was associated with an increased likelihood of engaging in violence (i.e., shooting or hitting someone with a weapon) compared with the BPP of the no use of marijuana trajectory group. Our results address a number of important public health and clinical issues. Public health funds might be spent on prevention programs focused on decreasing the use of marijuana, increasing educational retention, and decreasing contact with deviant associates. Understanding the psychosocial conditions related to the use of weapons is critical for individuals involved in the criminal justice system, physicians, and other health care providers in managing individuals who engage in violent behavior.
这是第一项评估城市中心非裔美国人和波多黎各人（N = 838）中使用大麻的轨迹以及暴力行为的其他预测因素与使用枪支或其他武器以及不使用武器进行盗窃之间关联的研究。逻辑回归分析检验了与不使用/低使用大麻轨迹相比，大麻使用的纵向轨迹是否能预测暴力行为。与不使用大麻轨迹组的贝叶斯后验概率（BPP）相比，大麻使用增加轨迹组（比值比[AOR]=3.37，P<0.001）、适度使用大麻轨迹组（AOR = 1.98，P<0.01）和戒断轨迹组（AOR = 1.70，P<0.05）的BPP与实施暴力行为（即使用武器射击或殴打他人）的可能性增加相关。我们的研究结果解决了一些重要的公共卫生和临床问题。公共卫生资金可用于开展预防项目，重点是减少大麻使用、提高教育保留率以及减少与不良同伴的接触。了解与武器使用相关的心理社会状况对于刑事司法系统中的人员、医生和其他医疗服务提供者管理实施暴力行为的个体至关重要。
