Open-label use of Highly* purified CBD (Epidiolex®) in patients with CDKL5 deficiency disorder and Aicardi, Dup15q, and Doose syndromes.

“We studied our collective open-label, compassionate use experience in using cannabidiol (CBD) to treat epilepsy in patients with CDKL5 deficiency disorder and Aicardi, Doose, and Dup15q syndromes. This open-label drug trial provides class III evidence for the long-term safety and efficacy of cannabidiol (CBD) administration in patients with treatment-resistant epilepsy (TRE) associated with CDKL5 deficiency disorder and Aicardi, Dup15q, and Doose syndromes. Adjuvant therapy with CBD showed similar safety and efficacy for these four syndromes as reported in a diverse population of TRE etiologies.” https://www.ncbi.nlm.nih.gov/pubmed/30006259 https://www.epilepsybehavior.com/article/S1525-5050(18)30191-4/fulltext

Composition and Use of Cannabis Extracts for Childhood Epilepsy in the Australian Community

Scientific Reports

“Recent surveys suggest that many parents are using illicit cannabis extracts in the hope of managing seizures in their children with epilepsy. In the current Australian study we conducted semi-structured interviews with families of children with diverse forms of epilepsy to explore their attitudes towards and experiences with using cannabis extracts.

Contrary to family’s expectations, most samples contained low concentrations of cannabidiol, while Δ9-tetrahydrocannabinol was present in nearly every sample. These findings highlight profound variation in the illicit cannabis extracts being currently used in Australia and warrant further investigations into the therapeutic value of cannabinoids in epilepsy.

The phenomenon is not without supporting scientific evidence. Many preclinical studies have identified potent anticonvulsant effects of various cannabinoids in animal models of epilepsy, and a mechanistic understanding of such effects is emerging.

A considerable proportion of families reported cannabis extracts being “effective” in reducing their child’s seizure burden and improving their overall condition, with one family reporting seizure-freedom in their child for at least 12 months. Over half of the cannabis extracts were associated with families reducing or ceasing their use of the child’s conventional antiepileptic drugs.”

The association between cannabis use and suicidal behavior in patients with psychiatric disorders: an analysis of sex differences.

Image result for bmc part of springer nature

“Cannabis is the most commonly used illicit drug. In the general population, its use has been linked to a heightened propensity for suicidal behavior (SB).

We hypothesize that this association varies in patients with psychiatric disorders. SB is known to vary by sex and therefore an investigation of cannabis‘ association with SB must consider sex differences.

The purpose of this study is to investigate the association between cannabis use and suicide attempts in men and women with psychiatric disorders.

We found no significant association between suicide attempts and cannabis use in men or women.

Our findings indicate that there is no association between cannabis use and suicidal behavior in men or women with psychiatric disorders unlike what was reported for the general population, though the heaviness of cannabis use may have an effect in men.

The impact of cannabis use in psychiatric disorders needs ongoing examination in light of its common use, impending legalization with expected increased access and the uncertainty about cannabis‘ effects on prognosis of psychiatric disorders.

In addition, research should continue to investigate modifiable risk factors of SB in this population of which cannabis is not a significant factor based on this study.”

Anti-Tumorigenic Properties of Omega-3 Endocannabinoid Epoxides.

Journal of Medicinal Chemistry

“Accumulating studies have linked inflammation to tumor progression.

Dietary omega-3 fatty acids including docosahexaenoic acid (DHA) have been shown to suppress tumor growth through their conversion to epoxide metabolites. Alternatively, DHA is converted enzymatically into docosahexaenoylethanolamide (DHEA), an endocannabinoid with anti-proliferative activity.

Recently, we reported a novel class of anti-inflammatory DHEA-epoxides (EDP-EAs) that contain both ethanolamide and epoxide moieties. Herein we evaluate the anti-tumorigenic properties of EDP-EAs in an osteosarcoma model.

First, we show ~80% increase in EDP-EAs in metastatic lungs versus normal mouse lungs. We found significant differences in the apoptotic and anti-migratory potency of the different EDP-EA regioisomers, which are partly mediated through cannabinoid receptor 1 (CB1).

Furthermore, we synthesized derivatives of the most pro-apoptotic regioisomer. These derivatives had reduced hydrolytic susceptibility to fatty acid-amide hydrolase and increased CB1 binding.

Collectively, we report a novel class of EDP-EAs that exhibit anti-angiogenic, anti-tumorigenic and anti-migratory properties in osteosarcoma.”

Marijuana use and fecundability in a North American preconception cohort study.

Image result for journal of epidemiology and community health

“The influence of marijuana use on human fertility has not been well studied. We evaluated the association between female and male use of marijuana and fecundability in Pregnancy Study Online, a prospective cohort of North American couples.

RESULTS:

Men (14.2%) were more likely than women (11.6%) to be marijuana users. FRs for female marijuana use <1 and ≥1 time/week relative to non-use were 0.99 (95% CI 0.85 to 1.16) and 0.98 (95% CI 0.80 to 1.20), respectively. FRs for male marijuana use <1 and ≥1 time/week relative to non-use were 0.87 (95% CI 0.66 to 1.15) and 1.24 (95% CI 0.90 to 1.70), respectively. Associations for frequent marijuana use (≥1 time/week) were attenuated among non-smoking men (FR=1.21, 95% CI 0.84 to 1.74), but stronger among men reporting intercourse ≥4 times/week (FR=1.35, 95% CI 0.72 to 2.53).

CONCLUSIONS:

In this preconception cohort study, there was little overall association between female or male marijuana use and fecundability.”

Can marijuana help eczema?

Logo of National Eczema Association

“A medical doctor and researchers in the cannabis industry explain the science behind cannabis as a potential treatment for atopic dermatitis.

Weed cream. THC lotion. CBD salve. They go by many names, and there is a lot of interest and hope in the dermatological community that marijuana—or cannabis—may provide an alternate treatment pathway for a variety of skin diseases, especially atopic dermatitis (AD).

Cannabinoids represent an exciting prospect for the future of AD therapy. With measurable anti-itch, anti-pain, anti-microbial and anti-inflammatory properties, the effect of cannabinoids in patients with AD has already begun to be demonstrated.”  https://nationaleczema.org/can-marijuana-help/

Enhancing the Therapeutic Efficacy of Cancer Treatment With Cannabinoids

Image result for frontiers in oncology

“Many in vitro and in vivo studies have reported on the antitumorigenic effects of plant-derived cannabinoids (CBDs) and their synthetic analogs, including effects in inducing apoptosis and inhibiting tumor cell growth and metastasis.

Over the years, many in vitro and in vivo studies have shown the antineoplastic effects of cannabinoids (CBDs), with reports advocating for investigations of combination therapy approaches that could better leverage these effects in clinical translation.

This study explores the potential of combination approaches employing CBDs with radiotherapy (RT) or smart biomaterials toward enhancing therapeutic efficacy during treatment of pancreatic and lung cancers. In in vitro studies, clonogenic assay results showed greater effective tumor cell killing, when combining CBDs and RT. Meanwhile, in vivo study results revealed major increase in survival when employing smart biomaterials for sustained delivery of CBDs to tumor cells. The significance of these findings, considerations for further research, and viable roadmap to clinical translation are discussed.

The advantage of combining CBDs with other therapies is that this may allow simultaneous targeting of tumor progression at different levels, while minimizing toxicities for these therapies relative to toxicities from higher doses when used as monotherapies.”

Cannabidiol reverses attentional bias to cigarette cues in a human experimental model of tobacco withdrawal.

Addiction banner

“Cannabidiol (CBD), a non-intoxicating cannabinoid, may be a promising novel smoking cessation treatment due to its anxiolytic properties, minimal side-effects and research showing it may modify drug cue salience.

We used an experimental medicine approach with dependent cigarette smokers to investigate if (1) overnight nicotine abstinence, compared with satiety, will produce greater attentional bias (AB), higher pleasantness ratings of cigarette-related stimuli and increased craving and withdrawal; (2) CBD in comparison to placebo, would attenuate AB, pleasantness of cigarette-related stimuli, craving and withdrawal and not produce any side-effects.

FINDINGS:

When participants received placebo, tobacco abstinence increased AB (p=.001, d =.789) compared with satiety. However, CBD reversed this effect, such that automatic AB was directed away from cigarette cues (p=.007, d= .704) and no longer differed from satiety (p=.82). Compared with placebo, CBD also reduced explicit pleasantness of cigarette images (p=.011; d=.514). Craving (Bayes Factor: 7.07) and withdrawal (Bayes Factor: 6.48) were unaffected by CBD, but greater in abstinence compared with satiety. Systolic blood pressure decreased under CBD during abstinence.

CONCLUSIONS:

A single 800mg oral dose of cannabidiol (CBD) reduced the salience and pleasantness of cigarette cues, compared with placebo, after overnight cigarette abstinence in dependent smokers. CBD did not influence tobacco craving or withdrawal or any subjectively rated side-effects.”

Relation of Cannabis Use and Atrial Fibrillation Among Patients Hospitalized for Heart Failure.

 The American Journal of Cardiology

“Left ventricular dysfunction triggers the activation of the sympathetic nervous system, providing inotropic support to the failing heart and concomitantly increasing the risk of atrial fibrillation (AF). The cardiovascular effects of cannabis have been characterized as biphasic on the autonomic nervous system with an increased sympathetic effect at low doses and an inhibitory sympathetic activity at higher doses. It is unknown if the autonomic effect of cannabis impacts the occurrence of AF in patients with heart failure (HF).

We used data from the Healthcare Cost and Utilization Project-National Inpatient Sample for patients admitted with a diagnosis of HF in 2014. The outcome variable was the diagnosis of AF, with the main exposure being cannabis use. We identified a cannabis user group and a 1:1 propensity-matched non-cannabis user group, each having 3,548 patients. We then estimated the odds of AF diagnosis in cannabis users. An estimated 3,950,392 patients were admitted with a diagnosis of HF in the United States in 2014. Among these, there were 17,755 (0.45%) cannabis users. In the matched cohort, cannabis users were less likely to have AF (19.08% vs 21.39%; AOR 0.87 [0.77 to 0.98]).

In conclusion, cannabis users have lower odds of AF when compared with nonusers, which was not explained by co-morbid conditions, age, insurance type, and socioeconomic status.”

Hemp shows potential for treating ovarian cancer

“Researchers demonstrate hemp’s ability to slow cancer growth and uncover mechanism for its cancer-fighting ability.

Results from some of the first studies to examine hemp’s ability to fight cancer show that it might one day be useful as plant-based treatment for ovarian cancer. Hemp is part of the same cannabis family as marijuana but doesn’t have any psychoactive properties or cause addiction.

“Hemp, like marijuana, contains therapeutically valuable components such as cannabidiol, cannabinol, and tetrahydrocannabinol,”

“Our findings from this research as well as prior research show that KY hemp slows ovarian cancer comparable to or even better than the current ovarian cancer drug Cisplatin,” said Turner. “Since Cisplatin exhibits high toxicity, we anticipate that hemp would carry less side effects.”
