ABSTRACT
A retrospective study of illicit phencyclidine (PCP), which consisted of 94 different cases or 213 individual samples, has shown that one third of both the powder/tablets and green plant material contained the synthetic contaminant 1-piperidinocyclohexanecarbonitrile (PCC). The mole % PCC/PCP ranged from 1 to 68%. The method of analysis was gas chromatography (3% OV-7, 205 degrees C) and in preparation for analysis the sample was dissolved directly in chloroform or extracted from a strongly acidic solution (0.1 N HCl). Using these extraction conditions PCC was found not to undergo measurable decomposition.

The demand for human artificial insemination (AI) is increasing as a function of declining numbers of babies available for adoption and greater community awareness. This paper reviews some of the social and legal issues associated with the practice of AI: prevalence of marital infertility; demand for AI; moral objections; effect on marriage; legality of practice; legal position of all the parties to the practice; legislation proposed to regulate the practice; and payment of medical benefits.
