Extended urinary Delta9-tetrahydrocannabinol excretion in chronic cannabis users precludes use as a biomarker of new drug exposure.
Drug Alcohol Depend. 105(1-2) , 24-32, (2009) Generally, urinary 11-nor-9-carboxy-Delta9-tetrahydrocannabinol (THCCOOH) after alkaline hydrolysis is monitored to detect cannabis exposure, although last use may have been weeks prior in chronic cannabis users. Delta9-Tetrahydrocannabinol (THC) and 11-hydro... |

[Interpretation of blood analysis data found after passive exposure to cannabis].
Arch. Kriminol. 225(3-4) , 90-8, (2010) When defendants are confronted with evidence of cannabinoids in their blood suggesting consumption of cannabis they sometimes argue that this could only be due to a passive exposure. The small number of controlled studies available showed that tetrahydrocanna... |

Identification of candidate genes affecting Delta9-tetrahydrocannabinol biosynthesis in Cannabis sativa.
J. Exp. Bot. 60(13) , 3715-26, (2009) RNA isolated from the glands of a Delta(9)-tetrahydrocannabinolic acid (THCA)-producing strain of Cannabis sativa was used to generate a cDNA library containing over 100 000 expressed sequence tags (ESTs). Sequencing of over 2000 clones from the library resul... |
