On March 2007, a police officer (46-year-old man) and a clerk (37-year-old woman) were arrested and subjected to investigation on the charges of drugs of abuse trafficking. The loving couple was exploiting their administrative positions to make money with the resale of seized drugs. The laboratory was requested to analyse their hair for drugs of abuse. Hair of the 2 subjects tested positive for heroin by GC-MS. A few days later, analysis of hair obtained from 11 other police officers of the same unit was requested, in order to compare the results, as external contamination was proposed to account for the positive results. The aim of the investigations was to demonstrate that passive contamination could not occur for persons dealing every day with drugs of abuse with minimal caution and hygiene, and that the measured concentrations in the arrested subjects correspond to personal abuse. All the narcotic team tested negative, irrespective of the compound.
2007 年 3 月，一名警察（男，46 岁）和一名办事员（女，37 岁）被捕并接受了滥用药物交易的指控。这对恩爱夫妻利用他们的行政职务，通过转售缉获的毒品来赚钱。实验室被要求分析他们的头发中的滥用药物。GC-MS 检测显示，这两名受试者的头发中都呈海洛因阳性。几天后，为了进行比较，请求分析同一单位的另外 11 名警察的头发，因为有人提出，阳性结果可能是由于外部污染。进行这些调查的目的是为了证明，对于那些每天在处理滥用药物时很少注意和卫生的人来说，被动污染不太可能发生，而且被捕者体内检测到的浓度与个人滥用药物的情况相符。所有的缉毒队人员检测结果均为阴性，与化合物无关。
