A radioimmunoassay specific for the closed, three-ringed cannabinoid nucleus was used to detect and measure caname from hospital inpatients not suspected of taking drugs. None of these contained tetrahydro-cannabinol cross-reacting cannabinoids (THC-CRC). The other 393 specimens were from patients known or suspected to be taking various drugs. Of these 51 out of 162 from one hospital treatment clinic and 19 out of 50 from another were positive for THC-CRC. Out of 107 urine specimens from an independent drug treatment clinic 71 were positive for THC-CRC, as were 13 out of 74 specimens from patients in whom drug misuse was suspected or thought possible.
一种针对封闭三环大麻素核的放射免疫分析法，用于检测和测量来自未被怀疑吸毒的医院住院患者的大麻酚。这些样本均不含有与四氢大麻酚发生交叉反应的大麻素（THC-CRC）。另外393个样本来自已知或疑似服用各种药物的患者。其中，来自一家医院治疗诊所的162个样本中有51个THC-CRC呈阳性，另一家医院的50个样本中有19个呈阳性。在一家独立药物治疗诊所的107份尿液样本中，71份THC-CRC呈阳性，在74份疑似或可能存在药物滥用的患者样本中，13份呈阳性。
