Abstract:
11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid is the biotransformation product of delta-9-tetrahydrocannabinol, that is the main active compound of the product from cannabis: marihuana and hashish. Its identification in urine is supposed to be the best indication of previous cannabis consumption. The aim of this study was to find conditions for the use of thin layer chromatography as an identification method of 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic in urine after positive preliminary screening of cannabinoids by EMIT method.
