Urine morphine levels after the consumption of poppy seeds were measured in two separate trials. Maximum levels of approximately 18 micrograms/ml were found using RIA, EMIT-ST and GC methodologies. Positive immunoassay results were seen up to 60 h post-ingestion. Several different lots of seeds from various sources were assayed for morphine and found to range from 4-200 mg/kg. Differentiation of poppy seed eaters from opiate users was not possible via the identification of minor alkaloid constituents of poppy seeds. It is, however, possible to analyse opiate urines with respect to 6-O-acetylmorphine. Below the level of approximately 5 micrograms/ml total opiates, GC/MS is the method of choice for this analysis.
在两项独立试验中测量了食用罂粟籽后的尿吗啡水平。使用放射免疫分析（RIA）、酶放大免疫分析技术（EMIT-ST）和气相色谱（GC）方法发现最大水平约为18微克/毫升。摄入后60小时内免疫分析结果呈阳性。对来自不同来源的几个不同批次的种子进行吗啡检测，发现含量范围为4 - 200毫克/千克。通过鉴定罂粟籽中的次要生物碱成分，无法区分食用罂粟籽者和阿片类药物使用者。然而，针对6 - O - 乙酰吗啡分析阿片类尿液是可行的。当总阿片类物质水平低于约5微克/毫升时，气相色谱/质谱联用（GC/MS）是此分析的首选方法。
