To validate information on cannabis use, 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic (THC-COOH) was investigated in human hair. The identification of THC-COOH in hair would document cannabis use more effectively than the detection of the parent drug which might have come from environmental

Cannabinoids in humans. I. Analysis of delta 9-tetrahydrocannabinol and six metabolites in plasma and urine using GC-MS.

Development and validation of a method for simultaneous identification and quantification of Delta9-tetrahydrocannabinol (THC), cannabidiol (CBD), cannabinol (CBN), and metabolites 11-hydroxy-THC (11-OH-THC) and 11-nor-9-carboxy-THC (THCCOOH) in oral fluid. Simultaneous analysis was problematic due

Exhaled breath has recently been proposed as a new possible matrix for drugs of abuse testing. A key drug is cannabis, and the present study was aimed at investigating the possibility of detecting tetrahydrocannabinol and tetrahydrocannabinol carboxylic acid in exhaled breath after cannabis smoking.

Testing human hair for cannabis.

To validate information on cannabis use, we investigated human hair and pubic hair for cannabinoids (THC and THC-COOH) by gas chromatography/mass spectrometry. Samples (100 mg approximately) were decontaminated with methylene chloride, then pulverized and dissolved in 1 ml 1 N NaOH for 10 min at 95

Background Cannabis smoke affects the lungs similarly to tobacco smoke, causing symptoms such as increased cough, sputum, hyperinflation and chronic bronchitis. Chronic use can also cause serious lung diseases and airway obstruction. We developed and validated a method for the identification and

Oxidative cleavage of the pentyl side-chain of cannabinoids. Identification of new biotransformation pathways in the metabolism of 4'-hydroxy-delta-9-tetrahydrocannabinol in the mouse.

During an investigation of the mechanisms leading to the formation of metabolites of cannabinoids in which the pentyl side chain is reduced to 2, 3 or 4 carbon atoms, the further metabolism of 4'-hydroxy-delta 9-tetrahydrocannabinol was investigated in vivo in mice. Metabolites were extracted with

Cannabinoids in humans. II. The influence of three methods of hydrolysis on the concentration of THC and two metabolites in urine.

Glucuronide conjugates of cannabinoids were previously identified in humans. For gas chromatographic-mass spectrometric (GC-MS) analysis of the unconjugated compounds in human urine, it is necessary to cleave the glucuronide moiety. Base hydrolysis and two forms of enzymatic hydrolysis were compared

This paper compares the methods used in Sevilla, Spain with those used in Strasbourg, France for analyzing cannabinoids (delta 9-tetrahydrocannabinol [THC] and 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid [THCCOOH]) in human hair. The Sevilla procedure involved the following steps: After

A simple and sensitive assay for the cannabinoids is presented using a dabsylation procedure. Dabsyl derivatives of delta 9-tetrahydrocannabinol (delta 9-THC) and cannabinol (CBN) were prepared by reacting with 4-dimethylaminoazobenzene-4'-sulfonyl chloride (dabsyl chloride) in acetone in the

Cannabis is the most widely abused drug in the world. The purpose of this study is to detect 11-nor-9-carboxy-Δ⁹-tetrahydrocannabinol (THCCOOH) in segmental hair and to evaluate the patterns of cannabis use. We investigated the relationship between the concentrations of THCCOOH in hair and the

Testing human hair for Cannabis. III. rapid screening procedure for the simultaneous identification of delta 9-tetrahydrocannabinol, cannabinol, and cannabidiol.

delta 9-Tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol (CBN) are three constituents of the 16 that can be currently isolated from some Cannabis spp plants. Their identification in decontaminated hair can indicate exposure to cannabis. In this study, we propose a rapid, simple, and

This work introduces an effective methodology for the isolation of acidic cannabinoids from fiber-type Cannabis sativa L. Supercritical fluid extraction (SFE) was initially employed to obtain an enriched extract of acidic cannabinoids. Subsequently, fractionation was performed by using centrifugal
