背景：本研究的目的是评估个体人口统计学和人格特征、城市一级医用大麻的实际可得性（通过每道路英里店面药房和配送服务的密度来衡量）以及大麻使用的发生率和流行程度之间的统计关联。方法：对加利福尼亚州50个中型城市的8853名受访者进行电话调查，收集个人层面的大麻使用数据。通过六个不同的网站和官方城市名单获得了医用大麻药房和配送服务的数据。使用随机效应逻辑模型（用于终生和过去一年的使用）和随机效应模型（用于过去365天的使用频率）分析了与寿命、过去一年的使用和过去一年的使用频率有关的三个结果变量。结果：目前的研究发现，在控制了各种人口统计学和人格特征的情况下，城市一级通过药房和每英里道路递送服务的医用大麻的总物理可得性与当前大麻使用和更高的使用频率呈正相关。正如预期的那样，目前医用大麻的实际可用性与终身使用无关。结论：对大麻销售点的数量和密度进行管制可能是抑制城市内大麻使用总体水平的充分手段。然而，另一种使用递送服务的方式也可能使人们更容易获得大麻，并减轻这些影响。2014爱思唯尔爱尔兰有限公司版权所有。
Background: The purpose of the current study is to assess statistical associations between individual demographic and personality characteristics, the city-level physical availability of medical marijuana (as measured through densities per roadway mile of storefront dispensaries and delivery services), and the incidence and prevalence of marijuana use.Method: Individual level data on marijuana use were collected during a telephone survey of 8853 respondents living in 50 mid-size cities in California. Data on medical marijuana dispensaries and delivery services were obtained via six different websites and official city lists. Three outcome variables pertaining to lifetime, past year use, and frequency of past year use were analyzed using random effects logistic models (for lifetime and past year use) and random effects tobit models (for frequency of past 365-day use).Results: The current study finds that the total physical availability of medical marijuana through dispensaries and delivery services per roadway mile at the city-level is positively related to current marijuana use and greater frequency of use, controlling for a variety of demographic and personality characteristics. As expected, current physical availability of medical marijuana was unrelated to lifetime use.Conclusions: Regulations on the number and densities of marijuana outlets may be a sufficient means to restrain overall levels of marijuana use within cities. However, alternative use of delivery services may also provide easy access to marijuana and mitigate these effects. (C) 2014 Elsevier Ireland Ltd. All rights reserved.
