Studies have shown that contamination of surfaces by illicit drugs frequently occurs in forensic laboratories when manipulating seized samples as well as in pharmacies and hospitals when preparing medicinal drugs. In this project, we extended these studies to a Drug Consumption Room to investigate drug levels and possible exposure of the staff members.
We investigated pre and post cleaning contamination by heroin and cocaine and their degradation products 6-monoacetylmorphine and benzoylecgonine on different surfaces (tables, counters, computers and door handles) and in the ambient air. We also collected urine and hair samples from staff members to check for potential short and long term contaminations.
Medium to heavy contamination has been detected on most surfaces and door handles; as expected, air contamination was particularly high in the smoking room. Drug levels were < LOD to very low in the urine and the hair samples of staff members tested.
The cleaning efficiency of the surfaces, carried out by staff and drug users after drug consumption, was often not satisfactory. The very low drug levels in hair indicate that acute health risks for staff members are low.
研究表明，在法医学实验室处理缴获的样本时，以及在药剂师和医院准备药物时，表面经常被非法药物污染。在这个项目中，我们将这些研究扩展到药物使用室，以调查药物水平和工作人员可能的暴露情况。
我们调查了在吸毒室不同表面（桌子、柜台、电脑和门把手）和环境空气中，海洛因和可卡因及其降解产物 6-单乙酰吗啡和苯甲酰古柯碱在清洁前后的污染情况。我们还收集了工作人员的尿液和头发样本，以检查潜在的短期和长期污染。
大多数表面和门把手上都检测到了中度到重度的污染；正如预期的那样，吸烟室的空气污染特别严重。工作人员尿液和头发样本中的药物水平<LOD 至非常低。
工作人员和吸毒者在吸毒后对表面进行的清洁效率往往不理想。头发中的药物水平非常低表明工作人员的急性健康风险较低。
