Detection of cannabis products in urine by radioimmunoassay.

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.

Pituitary function in chronic alcoholism.

Elevated basal LH levels and an exaggerated response to LHRH were found in a high proportion of male chronic alcoholics. This was not associated with reduced plasma testosterone values. In addition, previous reports of an absent cortisol response to hypoglycaemia in a proportion of chronic alcoholics are confirmed.

Application of urine analysis to diagnosis and treatment of heroin addiction.

Experience with urine analysis for morphine using thin-layer chromatography in 310 cases of real or possible heroin abuse showed that it was valuable not only in detecting improper drug use but also in monitoring treatment. The results of this test can be available routinely in 24, and exceptionally in five hours. A negative result implies that the subject has taken less than 10 mg. of heroin in the past 24 hours.
