Thirty persons arrested at Frankfurt airport for smuggling internally concealed cocaine in 1993/1994 were investigated. An X-ray examination (in all 30 cases), immunochemical examination of urine (in 27 cases) and of saliva (in 20 cases) was performed in parallel. An X-ray examination gave positive results in all examined persons. EMIT cocaine metabolite assay (cut off 300 ng benzoylecgonine (BE)/mL) was positive in eight urine samples. After reducing the cut off to 150 ng BE/mL urine, eleven samples were classified as positive. The results were confirmed by means of chromatographic determinations. These findings showed limited role of immunological examination of urine as a screening test in suspected smuggling of internally concealed drugs. All saliva samples showed negative immunochemical results. The number of concealed containers ranged from 44 to 135 per person. The amount of cocaine hydrochloride found in particular cases ranged from 242 to 1050 g net weight, divided into containers weighing from 5.7 to 13.8 g. Drug packages were obviously machine-made. The packages smuggled by a particular person were uniform. However, a distinct interpersonal variability in drug packages was observed, in regard to the number of protective layers (4-7), size, weight, and cocaine purity. This may be helpful for the identification of production site. The leaching of cocaine from selected containers was investigated in a stirring bath and was independent of the conditions applied.
对1993年/1994年在法兰克福机场因走私体内藏毒可卡因而被捕的30人进行了调查。同时进行了X线检查（共30例）、尿液免疫化学检查（27例）和唾液免疫化学检查（20例）。X线检查在所有受检者中均呈阳性结果。EMIT可卡因代谢物检测（截断值为300 ng苯甲酰爱康宁（BE）/mL）在8份尿液样本中呈阳性。将尿液截断值降至150 ng BE/mL后，11份样本被判定为阳性。结果通过色谱测定得到证实。这些结果表明，尿液免疫检查作为体内藏毒走私疑似病例的筛查试验作用有限。所有唾液样本的免疫化学结果均为阴性。每人体内藏毒容器数量为44至135个。个别案例中发现的盐酸可卡因净重为242至1050 g，分装在重5.7至13.8 g的容器中。毒品包装显然是机器制造的。特定人员走私的包装是统一的。然而，在保护层数量（4至7层）、尺寸、重量和可卡因纯度方面，不同人员的毒品包装存在明显差异。这可能有助于确定生产地点。在搅拌浴中研究了可卡因从选定容器中的浸出情况，结果表明浸出情况与所采用的条件无关。
