Abstract

Recently, many new techniques for the determination of tetrahydrocannabinol and other cannabinoids in blood, saliva, and urine have been described (16 papers at the March 1977 American Chemical Society National Meeting alone). Some investigations have reported positive findings in urine several days after a subject had smoked a single marihuana cigarette. The high sensitivity and often questionable specificity of such analyses pose serious potential problems of wide-ranging medicolegal and psychosocial importance. These include arbitrary labelling of individuals as drug abusers or as driving while under the influence of marihuana, and other pronouncements more characterized by zealousness than by reason. Hence, there is currently a great need for all parties making critical decisions based on tests for cannabinoids to be aware of the ramifications limitations of these analytical procedures.
