Tobacco shops, medical marijuana dispensaries (MMD), and off-sale alcohol outlets are legal and prevalent in South Los Angeles, California-a high-crime, low-income urban community of color. This research is the first to explore the geographic associations between these three legal drug outlets with surrounding crime and violence in a large low-income urban community of color. First, spatial buffer analyses were performed using point-location and publically accessible January-December 2014 crime data to examine the geography of all felony property and violent crimes occurring within 100, 200, 500, and 1000-foot buffers of these three legal drug outlet types across South Los Angeles. Next, spatial regression analyses explored the geographic associations between density of these outlets and property and violent crimes at the census tract level. Results indicated that mean property and violent crime rates within 100-foot buffers of tobacco shops and alcohol outlets-but not MMDs-substantially exceeded community-wide mean crime rates and rates around grocery/convenience stores (i.e., comparison properties licensed to sell both alcohol and tobacco). Spatial regression analyses confirmed that tobacco shops significantly positively associated with property and violent crimes after controlling for key neighborhood factors (poverty, renters, resident mobility, ethnic/racial heterogeneity). Thus, study findings provide the first empirical evidence that tobacco shops may constitute public health threats that associate with crime and violence in U.S. low-income urban communities of color. Implementing and enforcing control policies that regulate and monitor tobacco shops in these communities may promote community health by improving public safety.
在加利福尼亚州南洛杉矶,烟草专卖店、医用大麻药房(MMD)和非售酒商店都是合法且普遍存在的,这里是一个犯罪高发、低收入的有色人种城市社区。这项研究首次探索了这三种合法毒品销售点与周围犯罪和暴力行为之间的地理关联,研究地点是一个大型低收入有色人种城市社区。首先,使用点位置和公共 2014 年 1 月至 12 月的犯罪数据进行空间缓冲区分析,以检查这三种合法毒品销售点类型在南洛杉矶的 100 英尺、200 英尺、500 英尺和 1000 英尺缓冲区范围内发生的所有重罪财产犯罪和暴力犯罪的地理位置。接下来,空间回归分析探讨了这些销售点的密度与人口普查区层面的财产犯罪和暴力犯罪之间的地理关联。结果表明,烟草专卖店和酒精销售点 100 英尺缓冲区范围内的平均财产犯罪和暴力犯罪率——而不是医用大麻药房——大大超过了社区的平均犯罪率以及杂货店/便利店(即,同时获准销售酒精和烟草的可比财产)的犯罪率。空间回归分析证实,在控制关键邻里因素(贫困、租户、居民流动性、族裔/种族异质性)后,烟草专卖店与财产犯罪和暴力犯罪显著正相关。因此,研究结果首次提供了经验证据,表明烟草专卖店可能构成公共健康威胁,与美国低收入有色人种城市社区的犯罪和暴力行为有关。在这些社区实施和执行监管和监测烟草专卖店的控制政策,可能会通过改善公共安全来促进社区健康。
