The purpose of this study was to determine which persons reporting sexual assault to a hospital-based treatment centre may have been covertly drugged and to provide information about whether a sexual assault may have occurred. Each consecutive adolescent and adult presenting at a sexual assault treatment centre was screened for drug-facilitated sexual assault (DFSA). Urine was collected and tested for central nervous system active drugs. Oral, vaginal, and/or rectal swabs were tested for male DNA. Unexpected drugs were defined as those not reported as having been voluntarily consumed within the previous 72 h. Positive swabs for unexpected DNA were determined by whether the person reported having had consensual intercourse in the previous week. A total of 184 of 882 eligible participants met suspected DFSA criteria. Mean age was 25.8 years (SD=8.5), 96.2% were female and 64.7% White. Urine samples were positive for drugs in 44.9% of cases, alcohol in 12.9%, and both drugs and alcohol in 18.0%. The drugs found on toxicological screening were unexpected in 87 of the 135 (64.4%) cases with a positive drug finding and included cannabinoids (40.2%), cocaine (32.2%), amphetamines (13.8%), MDMA (9.2%), ketamine (2.3%), and GHB (1.1%). Male DNA was unexpected in 30 (46.9%) of 64 cases where it was found. Among those persons presenting to a sexual assault treatment centre with a suspicion of DFSA, the presence of unexpected drugs and male DNA was common, lending support for their contention that they had been intentionally drugged and sexually assaulted. Most unexpected drugs found were not those typically described as 'date rape drugs'.
本研究的目的是确定哪些向医院治疗中心报告遭受性侵犯的人可能被暗中下药，并提供有关是否可能发生性侵犯的信息。对每一位连续到性侵犯治疗中心就诊的青少年和成年人进行药物辅助性侵犯（DFSA）筛查。收集尿液并检测中枢神经系统活性药物。对口腔、阴道和/或直肠拭子进行男性DNA检测。意外药物定义为在前72小时内未报告为自愿服用的药物。意外DNA拭子阳性根据该人是否报告在前一周有过双方自愿的性交来确定。882名符合条件的参与者中共有184人符合疑似DFSA标准。平均年龄为25.8岁（标准差=8.5），96.2%为女性，64.7%为白人。44.9%的病例尿液样本药物检测呈阳性，12.9%酒精检测呈阳性，18.0%药物和酒精检测均呈阳性。在135例药物检测呈阳性的病例中，有87例（64.4%）毒理学筛查发现的药物为意外药物，包括大麻素（40.2%）、可卡因（32.2%）、苯丙胺（13.8%）、摇头丸（9.2%）、氯胺酮（2.3%）和γ-羟基丁酸（1.1%）。在发现男性DNA的64例病例中，有30例（46.9%）为意外发现。在那些因疑似DFSA到性侵犯治疗中心就诊的人中，意外药物和男性DNA的存在很常见，这支持了他们关于自己被故意下药和性侵犯的说法。发现的大多数意外药物并非通常所说的“约会强奸药物”。
