Estimation of phencyclidine in leafy mixtures and in vapor phase after smoking.
Five street samples of leafy material coated with phencyclidine (PCP) were analyzed by a gas chromatographic nitrogen detection assay. The samples contained 15.6+1.8% PCP by weight or 32.2+ 13.8 mg PCP per "joint". An aliquot of a joint was smoked with a laboratory apparatus and the vaporized PCP was collected on a filter. Only 22.6+8.0% of the PCP or 6.7+2.1 mg PCP, reached the filter. This amount is in an approximation of the dose of PCP which becomes available to the oral and pulmonary mucosa following the smoking of a single PCP coated joint.
