This study aims to examine whether periods of marijuana and other illicit drug dealing ("spells" of dealing) are associated with changes in young male offenders' gun carrying behavior.
This paper uses 84 months of data from a sample of 479 serious juvenile male offenders who were assessed every six months for three years and then annually for four years. At each assessment, participants reported on engagement in illicit behaviors, including drug dealing and gun carrying, in each month since the prior interview. We used fixed effects models to assess within-individual changes in participants' gun carrying immediately before, during, and right after a dealing spell, while controlling for relevant time varying confounds (e.g., gang involvement, exposure to violence). Additionally, we tested moderation by type of drug sold.
There was a slight increase in gun carrying right before a drug dealing spell ( = 1.3-1.4), then a more pronounced increase in gun carrying during the months of a drug dealing spell ( = 8.0-12.8). Right after a dealing spell ends, youths' gun carrying dropped dramatically, but remained significantly elevated relative to their baseline levels ( = 2.6-2.8). The association between drug dealing spells and increases in gun carrying was stronger when participants dealt hard drugs (e.g., cocaine, heroin) relative to marijuana.
These results suggest that designing and implementing programs to prevent the initiation of drug dealing and decrease involvement in drug dealing may help to substantially reduce illegal gun carrying and firearm violence among delinquent males.
本研究旨在探讨大麻及其他非法毒品交易时期(“交易时段”)是否与年轻男性罪犯携带枪支行为的变化有关。
本文使用了来自479名严重青少年男性罪犯样本的84个月数据,这些罪犯在三年中每六个月接受一次评估,之后四年每年接受一次评估。在每次评估时,参与者报告自上次访谈以来每个月参与的非法行为,包括毒品交易和携带枪支情况。我们使用固定效应模型来评估参与者在交易时段之前、期间和之后立即携带枪支的个体内部变化,同时控制相关的随时间变化的混杂因素(例如帮派参与、暴力暴露)。此外,我们还按所售毒品类型进行了调节检验。
在毒品交易时段之前,携带枪支情况略有增加(系数 = 1.3 - 1.4),然后在毒品交易时段的几个月中携带枪支情况有更明显的增加(系数 = 8.0 - 12.8)。交易时段结束后,青少年的携带枪支情况大幅下降,但相对于基线水平仍显著升高(系数 = 2.6 -
