关于跨境阻截的影响和不同类型干预措施对国际贩毒的影响的文献相对较少。这项研究确定了可卡因和海洛因的主要贩运路线，同时沿着比较了有针对性的和不协调的干预措施所产生的破坏性影响。它采用了社会网络的方法来确定可卡因和海洛因贩运的沿着路线，然后模拟不同的拦截策略对这两个贩运网络的影响。调查结果表明，根据各国在网络中的地位而不是根据交换的毒品数量来确定目标国家更有可能扰乱毒品流动。更具体地说，将执法资源集中于有几个流入或流出贩运联系的国家，或那些在生产国、过境国和消费国之间起中介作用的国家，在这方面似乎特别有效。如果特定贩运路线的边缘介数中心性得分较高，则针对这些路线的干预措施也可能有效。这项研究有助于对可卡因和海洛因国际贩运网络的脆弱性的现有认识，而且，还表明，在阻截国际贩运方面，由毒品驱动的战略可能比非战略性和非协调的干预措施更有效。
There is a relative dearth of literature on both the effects of cross-border interdictions and the impact of different types of interventions on international drug trafficking. This study identifies the main trafficking routes for cocaine and heroin, along with comparing the disruptive effects induced by targeted and non-coordinated interventions. It adopts a social network approach to identify the routes along which cocaine and heroin are trafficked, and then simulates the impact of different interdiction strategies on these two trafficking networks. The findings indicate that targeting countries based on their respective positions in the networks, as opposed to on the basis of the quantity of drugs exchanged, is more likely to disrupt drug flows. More specifically, concentrating law enforcement resources on countries with several incoming or outgoing trafficking connections, or those countries that mediate between producer, transit and consumer countries, would appear to be particularly effective in this regard. Interventions focused on specific trafficking routes are also likely to be effective if these routes have high edge betweenness centrality scores. This study contributes to extant understanding on the vulnerability of cocaine and heroin international trafficking networks, and, moreover, demonstrates that empirically-driven strategies are potentially more effective at interdicting international trafficking than non-strategic and non-coordinated interventions.
