Cannabinoid acids readily decarboxylate to the corresponding cannabinoid. Methods are available for the determination of Δ9‐tetrahydrocannabinol (THC) and its acids (THCA) and published data on the levels of these compounds in cannabis are summarized. Using gas and liquid chromatography, fresh cannabis (64 samples) and cannabis resin (26 samples) from different countries were examined. Wide variations in the relative amounts of THCA and THC in cannabis were found. For cannabis resin, a wide… 
Chemistry and Analysis of Phytocannabinoids and Other Cannabis Constituents
The Cannabis plant and its products consist of an enormous variety of chemicals. Some of the 483 compounds identified are unique to Cannabis, for example, the more than 60 cannabinoids, whereas the
Long term stability of cannabis resin and cannabis extracts
Investigation of the stability of cannabinoids in cannabis resin slabs and cannabis extracts upon long-term storage found the degradation rate of acidic THC increased significantly relative to resin material and once cannabis material is extracted into organic solvents, care should be taken to avoid the influence of sunlight.
Evaluation of tetrahydrocannabinolic acid (THCA) synthase polymorphisms for distinguishing between marijuana and hemp
This study optimized and evaluated a previously reported single nucleotide polymorphism (SNP) assay for determining C. sativa crop type and found that the SNP assay correctly identified crop type in most samples, however, several marijuana samples were classified as hemp, and several hemp seeds wereclassified as marijuana.
Affinity and Efficacy Studies of Tetrahydrocannabinolic Acid A at Cannabinoid Receptor Types One and Two
It is concluded that THCA-A has little affinity or efficacy at CB1 or CB2, which agrees with decarboxylation kinetics, which indicate contamination with THC is nearly unavoidable.
Pharmacokinetics and Pharmacodynamics of Cannabinoids
Properties of cannabis that might be of therapeutic use include analgesia, muscle relaxation, immunosuppression, sedation, improvement of mood, stimulation of appetite, antiemesis, lowering of intraocular pressure, bronchodilation, neuroprotection and induction of apoptosis in cancer cells.
Some Features of Cannabis Plants Grown in the United Kingdom from Seeds of Known Origin
The study concludes that the ratios of particular cannabinoids is greatly influenced by the environment.
Determination of ∆ 9-Tetrahydrocan-nabinolic Acid A in Serum Samples by GC-MS
The aim of this work was the extension of our standard procedure for quantitation of ∆9-tetrahydrocannabinol (∆9-THC) and its main metabolites by GC-MS for the simultaneous determination of
Validating a gas chromatography-mass spectrometric method and sample classification procedure for cannabis profiling using cannabinoids from case samples
A gas chromatography–mass spectrometric (GC–MS) method was evaluated for cannabis profiling. Method validation was carried out using four cannabinoids extracted from cannabis case samples. In the
The acute effects of tetrahydrocannabinol on auditory threshold and frequency resolution in human subjects
Investigating the acute effects of ingested tetrahydrocannabinol (THC) on auditory function suggests that THC at the plasma levels attained in this study does not have a profound effect on the processing of elementary stimuli by the auditory pathway.
