Cannabidiol attenuates seizures and EEG abnormalities in Angelman syndrome model mice.

 Image result for J Clin Invest.“Angelman syndrome (AS) is a neurodevelopmental disorder characterized by intellectual disability, lack of speech, ataxia, EEG abnormalities, and epilepsy. Seizures in AS individuals are common, debilitating, and often drug-resistant. Therefore, there is an unmet need for better treatment options.

Cannabidiol (CBD), a major phytocannabinoid constituent of cannabis, has antiseizure activity and behavioral benefits in preclinical and clinical studies for some disorders associated with epilepsy, suggesting that the same could be true for AS.

Here we show that acute CBD (100 mg/kg) attenuated hyperthermia- and acoustically-induced seizures in a mouse model of AS. However, neither acute CBD nor a two-weeklong course of CBD administered immediately after a kindling protocol could halt the pro-epileptogenic plasticity observed in AS model mice.

CBD had a dose-dependent sedative effect, but did not have an impact on motor performance. CBD abrogated the enhanced intracortical local field potential power, including delta and theta rhythms observed in AS model mice, indicating that CBD administration could also help normalize the EEG deficits observed in individuals with AS.

Our results provide critical preclinical evidence supporting CBD treatment of seizures and alleviation of EEG abnormalities in AS, and will thus help guide the rational development of CBD as an AS treatment.”

Role of the endocannabinoidome in human and mouse atherosclerosis.

“The Endocannabinoid (eCB) system and its role in many physiological and pathological conditions is well described and accepted, and includes cardiovascular disorders. However, the eCB system has been expanded to an “-ome”; the endocannabinoidome (eCBome) that includes endocannabinoid-related mediators, their protein targets and metabolic enzymes, many of which significantly impact upon cardiometabolic health. These recent discoveries are here summarized with a special focus on their potential involvement in atherosclerosis. We described the role of classical components of the eCB system (eCBs, CB1 and CB2 receptors) and eCB-related lipids, their regulatory enzymes and molecular targets in atherosclerosis. Furthermore, since increasing evidence points to significant cross-talk between the eCBome and the gut microbiome and the gut microbiome and atherosclerosis, we explore the possibility that a gut microbiome – eCBome axis has potential implications in atherosclerosis.”

Emerging role of cannabinoids and synthetic cannabinoid receptor 1/cannabinoid receptor 2 receptor agonists in cancer treatment and chemotherapy-associated cancer management

Journal of Cancer Research and Therapeutics“Cannabis was extensively utilized for its medicinal properties till the 19th century. A steep decline in its medicinal usage was observed later due to its emergence as an illegal recreational drug.

Advances in technology and scientific findings led to the discovery of delta-9-tetrahydrocannabinol (THC), the primary psychoactive compound of cannabis, that further led to the discovery of endogenous cannabinoids system consisting of G-protein-coupled receptors – cannabinoid receptor 1 and cannabinoid receptor 2 along with their ligands, mainly anandamide and 2-arachidonoylglycerol.  Endocannabinoid (EC) is shown to be a modulator not only for physiological functions but also for the immune system, endocrine network, and central nervous system.

Medicinal research and meta-data analysis over the last few decades have shown a significant potential for both THC and cannabidiol (CBD) to exert palliative effects. People suffering from many forms of advanced stages of cancers undergo chemotherapy-induced nausea and vomiting followed by severe and chronic neuropathic pain and weight loss.

THC and CBD exhibit effective analgesic, anxiolytic, and appetite-stimulating effect on patients suffering from cancer. Drugs currently available in the market to treat such chemotherapy-induced cancer-related ailments are Sativex (GW Pharmaceutical), Dronabinol (Unimed Pharmaceuticals), and Nabilone (Valeant Pharmaceuticals).

Apart from exerting palliative effects, THC also shows promising role in the treatment of cancer growth, neurodegenerative diseases (multiple sclerosis and Alzheimer’s disease), and alcohol addiction and hence should be exploited for potential benefits.

The current review discusses the nature and role of CB receptors, specific applications of cannabinoids, and major studies that have assessed the role of cannabinoids in cancer management.

Specific targeting of cannabinoid receptors can be used to manage severe side effects during chemotherapy, palliative care, and overall cancer management. Furthermore, research evidences on cannabinoids have suggested tumor inhibiting and suppressing properties which warrant reconsidering legality of the substance.

Studies on CB1 and CB2 receptors, in case of cancers, have demonstrated the psychoactive constituents of cannabinoids to be potent against tumor growth.

Interestingly, studies have also shown that activation of CB1 and CB2 cannabinoid receptors by their respective synthetic agonists tends to limit human cancer cell growth, suggesting the role of the endocannabinoid system as a novel target for treatment of cancers.

Further explorations are required to exploit cannabinoids for an effective cancer management.”

THE EFFECTS OF MEDICAL MARIJUANA DISPENSARIES ON ADVERSE OPIOID OUTCOMES

 Publication cover image“As more states enact laws liberalizing marijuana use and the U.S. opioid epidemic surges to unprecedented levels, understanding the relationship between marijuana and opioids is growing increasingly important.

Using a unique self‐constructed marijuana dispensary dataset, I estimate the impact of increased marijuana access on opioid‐related harms.

I exploit within‐ and across‐state variation in dispensary openings and find county‐level prescription opioid‐related fatalities decline by 11% following the opening a dispensary.

The estimated dispensary effects are qualitatively similar for opioid‐related admissions to treatment facilities. These results are strongest for males and suggest a substitutability between marijuana and opioids.”

THE EFFECTS OF RECREATIONAL MARIJUANA LEGALIZATION AND DISPENSING ON OPIOID MORTALITY

Publication cover image“This study documents how the changing legal status of marijuana has impacted mortality in the United States over the past two decades.

We use a difference‐in‐difference approach to estimate the effect of medical marijuana laws (MML) and recreational marijuana laws (RML) on fatalities from opioid overdoses, and we find that marijuana access induces sharp reductions in opioid mortality rates.

Our research corroborates prior findings on MMLs and offers the first causal estimates of RML impacts on opioid mortality to date, the latter of which is particularly important given that RMLs are far more expansive in scope and reach than MMLs.

In our preferred econometric specification, we estimate that RMLs reduce annual opioid mortality in the range of 20%–35%, with particularly pronounced effects for synthetic opioids. In further analysis, we demonstrate how RML impacts vary among demographic groups, shedding light on the distributional consequences of these laws.

Our findings are especially important and timely given the scale of the opioid crisis in the United States and simultaneously evolving attitudes and regulations on marijuana use.”

Olivia Newton John says medicinal cannabis is key to her cancer recovery

“Olivia Newton-John says medicinal marijuana is a key part of her treatment for stage four cancer. In an exclusive interview with 60 Minutes reporter Liz Hayes, Newton-John says that not only has cannabis assisted with her pain management, sleep and anxiety – but it’s having affects on her physical health too. “I’m incredibly pro cannabis,” she told Liz Hayes. “If I don’t take the cannabis, I can feel the pain so I know it’s working.”

 “Newton-John is maintaining her health with a combination of conventional and alternative medicines and remedies. But her husband of ten years, John Easterling, says he’s confident medicinal cannabis is contributing significantly to maintaining her health.
Easterling, who spent years cultivating herbs from the Amazon, has long held a strong belief in the medicinal power of plants. In a greenhouse at the Santa Barbara ranch the couple share in California, he grows various strains of cannabis that he uses to help treat his wife. “Cannabis can be used for so many things,” he told Hayes. “I don’t use the word cure…. but I’m confident. We had MRIs showing a lesser number of tumours, and the majority of the other ones are shrinking.”
 “Now a cannabis convert, Newton-John is joining the fight for medicinal cannabis to be legalised. She and Easterling want Australians to have greater access to the plant, like they do in their home state of California – where both medicinal and recreational cannabis is legal.  She’s also hoping to break down the stigma surrounding cannabis use.
“It’s not a drug, it’s a herb and a plant,” she told Hayes. “I think when people use the word drug, it’s a misconception as to what it is and it gets people thinking, ‘oh it’s just another drug’, but it’s not.” Doctors at the Olivia Newton-John Research Institute will conduct a clinical trial to determine the effectiveness of medicinal cannabis later this year.”

 Olivia Newton-John: “The choices of your treatment is a very personal thing. I can’t tell anyone else what they should do. I’d like to tell you all something that I did that people should know about. I’ve mixed traditional medicine and herbal medicine and homoeopathic medicine and a lot of mind-body spiritual focus. Staying positive and believing I can get well is really important. I’m very fortunate that I have a husband who’s a plant medicine man who helps me with herbs and medicinal cannabis, it’s been a huge part of my journey. I weaned myself off morphine with cannabis and I just want people to know that that is possible and it’s not going to kill you. If we can start teaching people that cannabis can help keep the pain away and not kill you, that’s an important message to get out there. I want to see an end to cancer in my lifetime.

Lifetime marijuana use in relation to insulin resistance in lean, overweight, and obese US adults.

Journal of Diabetes banner“Obese individuals are more likely to show insulin resistance (IR). However, limited population studies on marijuanause with markers of IR have yielded mixed results.

The aim of this study was to examine the association of marijuana use with IR in US adults with different body mass index (BMI) status.

RESULTS:

Of all 129 509 adults aged 18 to 59 years, 50.3% were women. In current obese marijuana consumers, mean FINS in those with less than four uses per month was 52% (95% confidence interval [CI] 19%-71%) lower than in never users. In former obese consumers with eight or more uses per month and who stopped marijuana use <12 months ago, mean FINS was 47% (95% CI 18%-66%) lower than in never users. Mean FINS in those who quit marijuana 12 to 119 and 120 months and more prior the survey was 36% (95% CI 7%-57%) and 36% (95% CI 10%-54%) lower, respectively.

CONCLUSIONS:

Marijuana use is associated with lower FINS and HOMA-IR in obese but not non-obese adults, even at low frequency of less than four uses per month. Former marijuana consumers with high lifetime use had significantly lower FINS levels that persisted, independent of the duration of time since last use.”

Association of Marijuana Laws With Teen Marijuana Use

Image result for jama pediatrics

“In the United States, 33 states and the District of Columbia have passed medical marijuana laws (MMLs), while 10 states and the District of Columbia have legalized the recreational use of marijuana.

A 2018 meta-analysis concluded that the results from previous studies do not lend support to the hypothesis that MMLs increase marijuana use among youth, while the evidence on the effects of recreational marijuana laws (RMLs) is mixed.

Here, we report estimates of the association between the legalization of marijuana and its use, simultaneously considering both MMLs and RMLs.

Consistent with the results of previous researchers, there was no evidence that the legalization of medical marijuana encourages marijuana use among youth.

Moreover, the estimates reported in the Table showed that marijuana use among youth may actually decline after legalization for recreational purposes.

This latter result is consistent with findings by Dilley et al and with the argument that it is more difficult for teenagers to obtain marijuana as drug dealers are replaced by licensed dispensaries that require proof of age.”

Use of Cannabis to Relieve Pain and Promote Sleep by Customers at an Adult Use Dispensary

Publication Cover

“Cannabis has been used for pain relief and to promote sleep for thousands of years. Over the past several decades in the United States (U.S.), a therapeutic role for cannabis in mainstream medicine has increasingly emerged. Medical cannabis patients consistently report using cannabis as a substitute for prescription medications. Both pain relief and sleep promotion are common reasons for cannabis use, and the majority of respondents who reported using cannabis for these reasons also reported decreasing or stopping their use of prescription or over-the-counter analgesics and sleep aids. While adult-use laws are frequently called “recreational,” implying that cannabis obtained through the adult use system is only for pleasure or experience-seeking, our findings suggest that many customers use cannabis for symptom relief.”
