The use of illicit substances for the purpose of drug-facilitated sexual assault (DFSA) poses a significant problem. There has been an increase in public awareness of this problem, and a recent invention in the form of a drink coaster claims to detect whether or not a beverage has been spiked with a so-called date rape drug. A person is instructed to place a drop of the suspect beverage onto two spots of the test, smear gently, and wait until dry. If either spot turns to a darker blue color, then a possible date rape drug has been detected by the coaster test. In an effort to determine the effectiveness of the coasters, various drugs that have been associated with drug-facilitated sexual assault were tested at different concentrations in a variety of common alcoholic and non-alcoholic beverages. It was found that although the coasters do detect the presence of GHB and ketamine, two drugs that have been associated with DFSA, there are limiting factors such as the high concentration of the drugs required, hindrance of the reaction due to beverage matrix, and extensive time requirements for ketamine analysis.
使用非法物质实施药物辅助性性侵（DFSA）是一个重大问题。公众对这一问题的认识有所提高，最近有一种杯垫形式的发明声称可以检测饮料是否被掺入了所谓的约会强奸药物。人们被指示将一滴可疑饮料滴到测试的两个点上，轻轻涂抹，然后等待干燥。如果任何一个点变成深蓝色，那么杯垫测试就检测到了可能的约会强奸药物。为了确定杯垫的有效性，在各种常见的酒精饮料和非酒精饮料中，对与药物辅助性性侵相关的各种药物进行了不同浓度的测试。结果发现，虽然杯垫确实能检测出与DFSA相关的两种药物γ-羟基丁酸（GHB）和氯胺酮的存在，但存在一些限制因素，如所需药物浓度高、饮料基质对反应的阻碍以及氯胺酮分析所需时间长。
