背景：自2000年以来，海洛因使用模式在美国发生了变化。这种变化与当地海洛因使用者使用多种药物的关系尚不清楚。虽然多种药物的使用进行了研究，用户对药物使用的健康风险，逮捕风险，可用性，成本，喜欢，和依赖性方面的看法还没有被considered.Methods：数据来自一个简短的，面对面的调查，在2016年进行的200个非治疗海洛因用户从克利夫兰，OH。我们评估了对酒精、大麻、甲基苯丙胺、海洛因、快克可卡因、可卡因粉和处方药的使用和态度。我们估计多药（同时过去一个月）使用聚类分析和潜在的配置文件。回归分析估计的强度之间的关系的态度和频率use.Results：我们确定了五个集群：集群1使用海洛因伴随着酒精和偶尔裂纹;集群2使用海洛因和快克可卡因每天;集群3使用海洛因每天，几乎完全;集群4使用海洛因和大麻每天;和集群5是兼职吸毒者。药物使用频率与无法获得药物时的喜好和焦虑有关。海洛因和可卡因的高感知可用性和低成本促进多药use.Conclusions：了解海洛因使用者之间的多药使用集群是重要的，为解决更大的阿片类药物流行。使用者对药物的可得性和成本的看法似乎促进了多种药物的使用，并证明有必要在今后对药物获取进行更详细的研究。
Background: Since 2000, heroin use patterns have shifted within the United States. How this change may relate to polydrug use among local heroin users is unknown. Although polydrug use has been studied, user perceptions of drug use in terms of health risks, arrest risk, availability, cost, liking, and dependence have not been considered.Methods: Data are presented from a brief, face-to-face survey conducted in 2016 of 200 non-in-treatment heroin users from Cleveland, OH. We assessed the use of and attitudes on alcohol, marijuana, methamphetamine, heroin, crack cocaine, powder cocaine, and prescription drugs. We estimated polydrug (concurrent past month) use with cluster analysis and latent profiles. Regression analysis estimated the strength of relationships between attitudes and frequency of use.Results: We identified five clusters: Cluster 1 used heroin concomitantly with alcohol and occasionally crack; Cluster 2 used heroin and crack cocaine daily; Cluster 3 used heroin daily and almost exclusively; Cluster 4 used heroin and marijuana daily; and Cluster 5 were part-time drug users. Drug use frequency was associated with liking and being anxious when drugs could not be obtained. High perceived availability of heroin and cocaine and low cost facilitated polydrug use.Conclusions: Understanding polydrug use clusters among heroin users is important for addressing the larger opioid epidemic. Users' perceptions of a drug's availability and cost appeared to facilitate polydrug use and justify more detailed future research on drug access.
