Cannabis and joints: scientific evidence for the alleviation of osteoarthritis pain by cannabinoids.
“Cannabis has been used for millennia to treat a multitude of medical conditions including chronic pain.
Osteoarthritis (OA) pain is one of the most common types of pain and patients often turn to medical cannabis to manage their symptoms.
While the majority of these reports are anecdotal, there is a growing body of scientific evidence which supports the analgesic potential of cannabinoids to treat OA pain.
OA pain manifests as a combination of inflammatory, nociceptive, and neuropathic pain, each requiring modality-specific analgesics. The body’s innate endocannabinoid system (ECS) has been shown to ameliorate all of these pain subtypes.
This review summarizes the components of the ECS and details the latest research pertaining to plant-based and man-made cannabinoids for the treatment of OA pain. Recent pre-clinical evidence supporting a role for the ECS to control OA pain is described as well as current clinical evidence of the efficacy of cannabinoids for treating OA pain in mixed patient populations.
The therapeutic effects of Cannabis and cannabinoids: An update from the National Academies of Sciences, Engineering and Medicine report
“The National Academies of Sciences, Engineering and Medicine conducted a rapid turn-around comprehensive review of recent medical literature on The Health Effects of Cannabis and Cannabinoids. In the Therapeutics chapter reviewed here, the report concluded that there was conclusive or substantial evidence that Cannabis or cannabinoids are effective for the treatment of pain in adults; chemotherapy-induced nausea and vomiting and spasticity associated with multiple sclerosis. Moderate evidence was found for secondary sleep disturbances. The evidence supporting improvement in appetite, Tourette syndrome, anxiety, posttraumatic stress disorder, cancer, irritable bowel syndrome, epilepsy and a variety of neurodegenerative disorders was described as limited, insufficient or absent. A chapter of the NASEM report enumerated multiple barriers to conducting research on Cannabis in the US that may explain the paucity of positive therapeutic benefits in the published literature to date. The 2017 National Academies of Sciences, Engineering and Medicine report, like the 1999 Institute of Medicine publication before it, did conclude that there is evidence to support the therapeutic effect of Cannabis and cannabinoids in a number of conditions. Although it is well appreciated that the plural of anecdote is not evidence, it must also be remembered that in the case of evaluating the therapeutic effects of Cannabis as published in the medical literature, the absence of evidence is not necessarily indicative of evidence of the absence of effectiveness. ” http://www.ejinme.com/article/S0953-6205(18)30003-7/fulltext
Cannabidiol to Improve Mobility in People with Multiple Sclerosis
“Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS) that affects an estimated 2.3 million people worldwide. The symptoms of MS are highly varied but frequently include pain, muscle spasticity, fatigue, inflammation, and depression. These symptoms often lead to reduced physical activity, negatively impact functional mobility, and have a detrimental impact on patients’ quality of life.
Although recent years have seen significant advances in disease modifying therapy, none of the current treatments halts or cures MS related symptoms. As a consequence, many people with MS (PwMS) look for alternative and complementary therapies such as cannabis.
The cannabis plant contains many biologically active chemicals, including ~60 cannabinoids. Cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) are typically the most concentrated chemical components of cannabis and believed to primarily drive therapeutic benefit.
There is evidence that CBD has a number of beneficial pharmacological effects. It is anti-inflammatory, antioxidative, antiemetic, antipsychotic, and neuroprotective. The review of 132 original studies by Bergamaschi et al. describes the safety profile of CBD by highlighting that catalepsy is not induced and physiological parameters (heart rate, blood pressure, and body temperature) are not altered. Moreover, psychomotor and psychological functions are not negatively affected. High doses of up to 1,500 mg per day and chronic use have been repeatedly shown to be well tolerated by humans.
Additionally, there is also evidence that CBD may reduce the negative psychotropic effects, memory impairment, and appetite stimulation, anxiety and psychotic-like states of THC while enhancing its positive therapeutic actions.
Anecdotal reports indicate that an increasing number of PwMS use cannabis (medical marijuana) as a supplement to improve their mobility.
Based on the following considerations, it is our opinion that CBD supplementation maybe advisable for PwMS to reduce fatigue, pain, spasticity, and ultimately improve mobility. “

“Humans have used marijuana for millennia, variously as a spiritual sacrament, herbal medicine, dietary supplement or psychoactive inebriant. Use of Medical Cannabis (MC) is advocated for an increasing range of medical indications. Anecdotally, use of naturally occurring cannabis (phytocannabinoids) is said to have a calming effect in some children. There has been little drug discovery work in the field of child and adolescent mental health for many years, and there is an urgent need to develop safe and effective therapeutics for this vulnerable patient group. Medical cannabis may be one such treatment. In summary, MC has potential as a therapeutic option in the management of paediatric mental health symptoms; however, the evidence to support its use for these patients is not yet in. ” https://onlinelibrary.wiley.com/doi/full/10.1111/jpc.13902]]>
The Role of Cannabis Legalization in the Opioid Crisis

“The United States remains gripped by the opioid crisis. Each day, 90 Americans die from opioid overdoses. Owing to the incredible reach of the opioid crisis—it has affected people of every race, sex, and age across our country—many stakeholders are trying to combat the crisis using multipronged approaches emphasizing prevention, treatment, and law enforcement.
In this issue of JAMA Internal Medicine, Bradford et al and Wen and Hockenberry report results suggesting that cannabis legalization may play a beneficial role in the opioid crisis.”

“Chronic cannabis use has been associated with impaired cognition and elevated psychological symptoms, particularly psychotic-like experiences. While Δ9-tetrahydrocannabinol (THC) is thought to be primarily responsible for these deleterious effects, cannabidiol (CBD) is purported to have antipsychotic properties and to ameliorate cognitive, symptomatic, and brain harms in cannabis users. However, this has never been tested in a prolonged administration trial in otherwise healthy cannabis users. Here, we report the first study of prolonged CBD administration to a community sample of regular cannabis users in a pragmatic trial investigating potential restorative effects of CBD on psychological symptoms and cognition.
Results: CBD was well tolerated with no reported side effects; however, participants retrospectively reported reduced euphoria when smoking cannabis. No impairments to cognition were found, nor were there deleterious effects on psychological function. Importantly, participants reported significantly fewer depressive and psychotic-like symptoms at PT relative to BL, and exhibited improvements in attentional switching, verbal learning, and memory. Increased plasma CBD concentrations were associated with improvements in attentional control and beneficial changes in psychological symptoms. Greater benefits were observed in dependent than in nondependent cannabis users.
Conclusions:Prolonged CBD treatment appears to have promising therapeutic effects for improving psychological symptoms and cognition in regular cannabis users. Our findings require replication given the lack of a placebo control in this pragmatic trial, but suggest that CBD may be a useful adjunct treatment for cannabis dependence.”
“Research on the antiepileptic effects of (endo-)
“We examined the effects of essential oil from legal (THC <0.2% w/v) hemp variety on the nervous system in 5 healthy volunteers. GC/EIMS and GC/FID analysis of the EO showed that the main components were myrcene and β-caryophyllene.
The experiment consisted of measuring autonomic nervous system (ANS) parameters; evaluations of the mood state; and electroencephalography (EEG) recording before treatment, during treatment, and after hemp inhalation periods as compared with control conditions. The results revealed decreased diastolic blood pressure, increased heart rate, and significant increased skin temperature.
The subjects described themselves as more energetic, relaxed, and calm.
The analysis EEG showed a significant increase in the mean frequency of alpha (8-13 Hz) and significant decreased mean frequency and relative power of beta 2 (18,5-30 Hz) waves. Moreover, an increased power, relative power, and amplitude of theta (4-8 Hz) and alpha brain waves activities and an increment in the delta wave (0,5-4 Hz) power and relative power was recorded in the posterior region of the brain.
These results suggest that the brain wave activity and ANS are affected by the inhalation of the EO of
