“Background: A small body of evidence suggests medical cannabis may facilitate wound healing, but the exact mechanism of this effect is unclear.

Purpose: This case report describes a patient with a pressure injury (PI) who received cannabis oil treatment for pain management and sleep improvement.

Methods: A 37-year-old woman with multiminicore disease, scoliosis, short-chain acyl-CoA dehydrogenase deficiency, and epilepsy presented to the Neurology Centre of Toronto with chronic pain and sleep disturbance, including difficulty initiating and maintaining sleep. She also had a 5-year history of a PI between her right iliac crest and right rib cage that had progressively worsened. The patient received a medical cannabis oil protocol that used a combination of cannabidiol and tetrahydrocannabinol.

Results: Cannabis oil was effective in treating pain and sleep difficulties. Unexpectedly, during the first 2 weeks of treatment, the PI started to heal and was almost completely closed at the 2-month follow-up.

Conclusion: Although it is unknown if the observed healing of this refractory PI was indirectly or directly related to the cannabidiol and tetrahydrocannabinol treatment, the potential relationships among pain, sleep disturbance, cannabis treatment, and healing should be explored.”

“Background: Little is known about cannabis use for insomnia in individuals with depression, anxiety, and comorbid depression and anxiety. To develop a better understanding of distinct profiles of cannabis use for insomnia management, a retrospective cohort study was conducted on a large naturalistic sample.

Methods: Data were collected using the medicinal cannabis tracking app, Strainprint®, which allows users to monitor and track cannabis use for therapeutic purposes. The current study examined users managing insomnia symptoms in depression (n = 100), anxiety (n = 463), and comorbid depression and anxiety (n = 114), for a total of 8476 recorded sessions. Inferential analyses used linear mixed effects modeling to examine self-perceived improvement across demographic variables and cannabis product variables.

Results: Overall, cannabis was perceived to be efficacious across all groups, regardless of age and gender. Dried flower and oral oil were reported as the most used and most efficacious product forms. In the depression group, all strains were perceived to be efficacious and comparisons between strains revealed indica-dominant (Mdiff = 1.81, 95% CI 1.26-2.36, Padj < .001), indica hybrid (Mdiff = 1.34, 95% CI 0.46-2.22, Padj = .045), and sativa-dominant (Mdiff = 1.83, 95% CI 0.68-2.99, Padj = .028) strains were significantly more efficacious than CBD-dominant strains. In anxiety and comorbid conditions, all strain categories were perceived to be efficacious with no significant differences between strains.

Conclusions: In terms of perceptions, individuals with depression, anxiety, and both conditions who use cannabis for insomnia report significant improvements in symptom severity after cannabis use. The current study highlights the need for placebo-controlled trials investigating symptom improvement and the safety of cannabinoids for sleep in individuals with mood and anxiety disorders.”

ijms-logo“The Endocannabinoid System (ECS) is primarily responsible for maintaining homeostasis, a balance in internal environment (temperature, mood, and immune system) and energy input and output in living, biological systems.

In addition to regulating physiological processes, the ECS directly influences anxiety, feeding behaviour/appetite, emotional behaviour, depression, nervous functions, neurogenesis, neuroprotection, reward, cognition, learning, memory, pain sensation, fertility, pregnancy, and pre-and post-natal development.

The ECS is also involved in several pathophysiological diseases such as cancer, cardiovascular diseases, and neurodegenerative diseases. In recent years, genetic and pharmacological manipulation of the ECS has gained significant interest in medicine, research, and drug discovery and development.

The distribution of the components of the ECS system throughout the body, and the physiological/pathophysiological role of the ECS-signalling pathways in many diseases, all offer promising opportunities for the development of novel cannabinergic, cannabimimetic, and cannabinoid-based therapeutic drugs that genetically or pharmacologically modulate the ECS via inhibition of metabolic pathways and/or agonism or antagonism of the receptors of the ECS. This modulation results in the differential expression/activity of the components of the ECS that may be beneficial in the treatment of a number of diseases.

This manuscript in-depth review will investigate the potential of the ECS in the treatment of various diseases, and to put forth the suggestion that many of these secondary metabolites of Cannabis sativa L. (hereafter referred to as “C. sativa L.” or “medical cannabis”), may also have potential as lead compounds in the development of cannabinoid-based pharmaceuticals for a variety of diseases.”

See the source image “Anxiety disorders in young people are frequently comorbid with other mental disorders and respond unsatisfactorily to first-line treatment in many cases.

Here, we report the case of a 20-year-old man with severe social anxiety disorder, major depressive disorder, insomnia and attenuated psychotic symptoms despite ongoing treatment with cognitive behavioural therapy and mirtazapine who was treated with adjunctive cannabidiol (CBD) in doses between 200 and 800 mg/day for 6 months.

During treatment with CBD, he experienced subjective benefits to his anxiety, depression and positive symptoms during treatment that were confirmed by clinicians and by standardised research instruments.

Findings from this case study add to existing evidence in support of the safety of CBD and suggest that it may be useful for young people with treatment refractory anxiety and for attenuated psychotic symptoms.”

Journal of the American Geriatrics Society “Background/objectives: Use of cannabis is increasing in a variety of populations in the United States; however, few investigations about how and for what reasons cannabis is used in older populations exist.

Design: Anonymous survey.

Setting: Geriatrics clinic.

Participants: A total of 568 adults 65 years and older.

Intervention: Not applicable.

Measurements: Survey assessing characteristics of cannabis use.

Results: Approximately 15% (N = 83) of survey responders reported using cannabis within the past 3 years. Half (53%) reported using cannabis regularly on a daily or weekly basis, and reported using cannabidiol-only products (46%).

The majority (78%) used cannabis for medical purposes only, with the most common targeted conditions/symptoms being pain/arthritis (73%), sleep disturbance (29%), anxiety (24%), and depression (17%). Just over three-quarters reported cannabis “somewhat” or “extremely” helpful in managing one of these conditions, with few adverse effects.

Just over half obtained cannabis via a dispensary, and lotions (35%), tinctures (35%), and smoking (30%) were the most common administration forms. Most indicated family members (94%) knew about their cannabis use, about half reported their friends knew, and 41% reported their healthcare provider knowing. Sixty-one percent used cannabis for the first time as older adults (aged ≥61 years), and these users overall engaged in less risky use patterns (e.g., more likely to use for medical purposes, less likely to consume via smoking).

Conclusion: Most older adults in the sample initiated cannabis use after the age of 60 years and used it primarily for medical purposes to treat pain, sleep disturbance, anxiety, and/or depression. Cannabis use by older adults is likely to increase due to medical need, favorable legalization, and attitudes.”

Cannabis use is associated with greater total sleep time in middle-aged and older adults with and without HIV: A preliminary report utilizing digital health technologies

“Current literature on the effect of cannabis use on sleep quality is mixed, and few studies have used objectively-measured sleep measures or real-time sampling of cannabis use to examine this relationship.

The prevalence of cannabis use among older adults and persons living with HIV has increased in recent years, and poor sleep quality is elevated in these populations as well. However, research examining cannabis-sleep relationships in these populations is lacking. Thus, we aimed to examine the relationship between daily cannabis use and subsequent objectively-measured sleep quality in middle-aged and older adults with and without HIV.

In this pilot study, seventeen (11 HIV+, 6 HIV-) adults aged 50-70 who consumed cannabis completed four daily smartphone-based surveys for 14 days, in which they reported their cannabis use (yes/no) since the last survey. Participants also wore actigraphy watches during the 14-day period to objectively assess sleep quality (i.e., efficiency, total sleep time, and sleep fragmentation).

In linear mixed-effects models, cannabis use was significantly associated with greater subsequent total sleep time (β=0.56; p=0.046). Cannabis use was not related to a change in sleep efficiency (β=1.50; p=0.46) nor sleep fragmentation (β=0.846, p=0.756) on days with cannabis use versus days without cannabis use.

These preliminary results indicate cannabis use may have a positive effect on sleep duration in middle-aged and older adults. However, future studies with larger sample sizes that assess cannabis use in more detail (e.g., route of administration, dose, reason for use) are needed to further understand this relationship.”

April 2020 cover“A randomized double-blind clinical trial evaluating the efficacy of a medicinal cannabis formulation (ZTL-101; Zelira Therapeutics Ltd, Perth, Australia) for treating chronic insomnia showed that the therapy is effective and safe.

Participants treated with medicinal cannabis went to sleep faster, slept significantly longer, and went back to sleep sooner after waking. Those participants reported significant improvements in quality of life, including feeling rested after sleep, feeling less stressed and less fatigued, and overall improved functioning.

For the trial, 23 participants were treated with the therapy for 14 nights, and after a 1-week washout period, received a placebo for 14 nights. Each participant took a single dose (.5 ml of 11.5 mg total cannabinoids) or a double dose (1 ml of 23 mg total cannabinoids) of the therapy, delivered sublingually, according to their symptoms.

“The fact that ZTL-101 treatment achieved statistically significant, dose-responsive improvements across a broad range of key insomnia indices is impressive, particularly given the relatively short 2-week dosing window,” said Peter Eastwood, director, Centre for Sleep Science, University of Western Australia.”

Possible therapeutic applications of cannabis in the neuropsychopharmacology field.

Posted on by

European Neuropsychopharmacology“Cannabis use induces a plethora of actions on the CNS via its active chemical ingredients, the so-called phytocannabinoids.

These compounds have been frequently associated with the intoxicating properties of cannabis preparations. However, not all phytocannabinoids are psychotropic, and, irrespective of whether they are psychotropic or not, they have also shown numerous therapeutic properties.

These properties are mostly associated with their ability to modulate the activity of an intercellular communication system, the so-called endocannabinoid system, which is highly active in the CNS and has been found altered in many neurological disorders.

Specifically, this includes the neuropsychopharmacology field, with diseases such as schizophrenia and related psychoses, anxiety-related disorders, mood disorders, addiction, sleep disorders, post-traumatic stress disorder, anorexia nervosa and other feeding-related disorders, dementia, epileptic syndromes, as well as autism, fragile X syndrome and other neurodevelopment-related disorders.

Here, we gather, from a pharmacological and biochemical standpoint, the recent advances in the study of the therapeutic relevance of the endocannabinoid system in the CNS, with especial emphasis on the neuropsychopharmacology field. We also illustrate the efforts that are currently being made to investigate at the clinical level the potential therapeutic benefits derived from elevating or inhibiting endocannabinoid signaling in animal models of neuropsychiatric disorders.”

Brain Research Bulletin“Cannabidiolic acid methyl ester (HU-580) is a more stable compound than cannabidiolic acid (CBDA) which has been shown to be effective in reducing nausea, anxiety, depression behaviors in animal models.

Here we extend the investigation of this compound to determine its effect on the sleep-wake cycle in male Wistar rats.

HU-580 dose-dependently (0.1, 1.0 or 100 µg/Kg, i.p.) prolonged wakefulness (W) and decreased slow wave sleep (SWS) duration whereas rapid eye movement sleep (REMS) showed no statistical change. In addition, the brain microdialysis probes either placed at nucleus accumbens (NAc) or into the basal forebrain in freely moving animals were used to evaluate the effects of HU-580 treatment on neurotransmitters related to the sleep-wake cycle modulation. HU-580 enhanced extracellular levels of dopamine, serotonin collected from NAc while adenosine and acetylcholine were increased in basal forebrain.

In summary, HU-580 seems to possess wake-promoting pharmacological properties and enhances the levels of wake-related neurochemicals. This is the first report of effects of HU-580 on sleep modulation expanding the very limited existent data on the neurobiological effects of HU-580 on rats.”
