Substance use is associated with anger and violence, however the extent of substance use among stalkers has not yet been systematically mapped. The aim of this scoping review was to identify substance use behaviour among stalkers who have been charged or convicted for stalking behaviour. A scoping review was conducted, and nine studies met the inclusion criteria. Substance use among stalkers was inconsistently defined and therefore the percentage of stalkers who used substances ranged from 0 % to 64 %. Substance use was most commonly defined by a psychiatric diagnosis while substance use immediately before or during the stalking offence was reported infrequently. Studies defining substance use more stringently reported lower proportions of substance use among stalkers. Few studies differentiated between alcohol and drug use or considered comorbidity. Overall, this review identified stalkers' substance use as a research gap; few studies met the inclusion criteria, contemporary evidence was sparse, and there was an absence of research underpinned by addiction or non-forensic clinical perspectives. Future research should consider the temporal proximity of stalkers' substance use with their stalking behaviour as this may have greater relevance to intervention than the presence of a diagnostic history.

跟踪者和药物使用：范围界定审查

药物使用与愤怒和暴力有关，但跟踪者的药物使用程度尚未系统地绘制出来。本次范围审查的目的是确定因跟踪行为而被指控或定罪的跟踪者中的药物使用行为。进行了范围界定审查，九项研究符合纳入标准。缠扰者使用药物的定义不一致，因此使用药物的缠扰者比例从 0% 到 64% 不等。药物使用最常见的定义是精神病学诊断，而在跟踪犯罪之前或期间使用药物的情况很少有报告。对物质使用进行更严格定义的研究表明，跟踪者中物质使用的比例较低。很少有研究区分饮酒和吸毒或考虑合并症。总体而言，本次审查将跟踪者的药物使用确定为研究空白；很少有研究符合纳入标准，当代证据很少，并且缺乏以成瘾或非法医临床观点为基础的研究。未来的研究应该考虑跟踪者的药物使用与其跟踪行为的时间接近性，因为这可能比诊断史的存在与干预具有更大的相关性。
