Subtypes of attention deficit-hyperactivity disorder (ADHD) and cannabis use.

“The current study examined the association between subtypes of attention-deficit/hyperactivity disorder (ADHD) and cannabis use within a sample of 2811 current users.

When asked about the ADHD symptoms they have experienced when not using cannabis, a higher proportion of daily users met symptom criteria for an ADHD diagnoses of the subtypes that include hyperactive-impulsive symptoms than the inattentive subtype.

For nondaily users, the proportions of users meeting symptom criteria did not differ by subtype.

These results have implications for identifying which individuals with ADHD might be more likely to self-medicate using cannabis. Furthermore, these findings indirectly support research linking relevant cannabinoid receptors to regulatory control.”

(+/-)9,10-Dihydroxy-delta6a(10a)-tetrahydrocannabinol and (+/-)8,9-dihydroxy-delta6a(10a)-tetrahydrocannabinol: 2 new cannabinoids from Cannabis sativa L.

“The structures of 2 new polyhydroxylated cannabinoids, (+/-)9,10-dihydroxy-delta6a(10a)-tetrahydrocannabinol and (+/-)8,9-dihydroxy-delta6a(10a)-tetrahydrocannabinol, obtained from a hexane extract of an Indian Cannabis variant were determined by spectral means and correlation with cannabinol.”

Cannabinoid compounds in South African Cannabis sativa L.

“Dagga (Cannabis sativa L.) samples were collected from various geographical regions of South Africa. These were classified into age, sex and plant part and the cannabinoids were analysed quantitatively by gas-liquid chromatography and mass spectrometry. Analytical results show that there appears to be at least three chemovariants of Cannabis sativa growing in South Africa with respect to relative cannabinoid content. One of these variants appears to be unique to Southern Africa. It also appears that South African C. sativa ranks among the world’s more potent C. sativa variants in terms of its delta 9-tetrahydrocannabinol content.”

Isolation and Pharmacological Evaluation of Minor Cannabinoids from High-Potency Cannabis sativa.

“Seven new naturally occurring hydroxylated cannabinoids (1-7), along with the known cannabiripsol (8), have been isolated from the aerial parts of high-potency Cannabis sativa.

The structures of the new compounds were determined by 1D and 2D NMR spectroscopic analysis, GC-MS, and HRESIMS as 8α-hydroxy-Δ9-tetrahydrocannabinol (1), 8β-hydroxy-Δ9-tetrahydrocannabinol (2), 10α-hydroxy-Δ8-tetrahydrocannabinol (3), 10β-hydroxy-Δ8-tetrahydrocannabinol (4), 10α-hydroxy-Δ9,11-hexahydrocannabinol (5), 9β,10β-epoxyhexahydrocannabinol (6), and 11-acetoxy-Δ9-tetrahydrocannabinolic acid A (7).

The binding affinity of isolated compounds 1-8, Δ9-tetrahydrocannabinol, and Δ8-tetrahydrocannabinol toward CB1 and CB2 receptors as well as their behavioral effects in a mouse tetrad assay were studied.

The results indicated that compound 3, with the highest affinity to the CB1 receptors, exerted the most potent cannabimimetic-like actions in the tetrad assay, while compound 4 showed partial cannabimimetic actions. Compound 2, on the other hand, displayed a dose-dependent hypolocomotive effect only.”

Cannabidiol Rescues Acute Hepatic Toxicity and Seizure Induced by Cocaine.

“Cocaine is a commonly abused illicit drug that causes significant morbidity and mortality. The most severe and common complications are seizures, ischemic strokes, myocardial infarction, and acute liver injury. Here, we demonstrated that acute cocaine intoxication promoted seizure along with acute liver damage in mice, with intense inflammatory infiltrate.

Considering the protective role of the endocannabinoid system against cell toxicity, we hypothesized that treatment with an anandamide hydrolysis inhibitor, URB597, or with a phytocannabinoid, cannabidiol (CBD), protects against cocaine toxicity.

URB597 (1.0 mg/kg) abolished cocaine-induced seizure, yet it did not protect against acute liver injury.

Using confocal liver intravital microscopy, we observed that CBD reduced acute liver inflammation and damage induced by cocaine and prevented associated seizure.

Additionally, we showed that previous liver damage induced by another hepatotoxic drug (acetaminophen) increased seizure and lethality induced by cocaine intoxication, linking hepatotoxicity to seizure dynamics.

These findings suggest that activation of cannabinoid system may have protective actions on both liver and brain induced by cocaine, minimizing inflammatory injury promoted by cocaine, supporting its further clinical application in the treatment of cocaine abuse.”

[Cannabinoids in medicine].

“Cannabinoids have been known for many centuries because of their various effects in healthcare. They are primarily effective in reducing nausea, vomiting, pain, anorexia, spasticity and depression. Some other effects are known, all seem to be mediated by cannabinoid receptors in the central nervous system. In the past years, medical use has been proven in several studies. Today, the therapeutical use of cannabinoids in medicine is increasing, and access was made easier. Especially in pain-management and palliative care, they seem to be a valuable therapeutic option.”

Impact of cannabis treatment on the quality of life, weight and clinical disease activity in inflammatory bowel disease patients: a pilot prospective study.

“Inflammatory bowel disease (IBD) patients suffer from significant morbidity and diminished life quality.

The plant cannabis is beneficial in various gastrointestinal diseases, stimulating appetite and causing weight gain.

Our aims were to assess whether treatment with inhaled cannabis improves quality of life, disease activity and promotes weight gain in these patients.

CONCLUSIONS:

Three months’ treatment with inhaled cannabis improves quality of life measurements, disease activity index, and causes weight gain and rise in BMI in long-standing IBD patients.”

A Dramatic Response to Inhaled Cannabis in a Woman with Central Thalamic Pain and Dystonia

“Central pain syndromes (CPS) are difficult to treat… The clinical utility of cannabinoids has been suggested on the basis of anecdotal reports and small clinical studies for a wide range of pain syndromes, including cancer pain, visceral pain, migrain, and pain associated with spasticity. We report a patient with intractable CPS who experienced dramatic relief of pain and dystonia from cannabis… Our case report illustrates improvement in control of central pain and dystonia, and discontinuation of other treatments following cannabis use, suggesting a role for cannabinoids in the management of central pain syndromes with dystonia.”
