The most common symptoms of arthritis include pain during daily movements and swelling of the joints. A study by U.S. researchers encourages sufferers: taking CBD appears to have positive effects on pain and physical functioning. In addition, an improvement in sleep quality was observed during therapy with medical cannabis. 

As part of the study, 428 patients suffering from joint pain were anonymously interviewed about the efficacy of CBD. Participants were recruited via social media and activities of the US patient associations “Arthritis Foundation” and “Savvy Cooperative”. The results are promising: CBD therapy is associated with improvements in pain (83 percent), physical functioning (66 percent) and sleep quality (66 percent). Especially those patients who had been diagnosed with osteoarthritis benefited from pain reduction through pharmaceutical cannabis.   

The majority of respondents also reported that their use of other pain medications had decreased or even stopped altogether as a result of taking CBD. 

The authors of the study advocate greater openness to alternative treatment options for inflammatory joint conditions such as arthritis – for example CBD therapy. In addition, further clinical studies are needed to explore the efficacy of cannabinoids in pain management for these conditions.

Many people who suffer from cancer have distressing symptoms such as pain and fatigue, but also  psychological complaints such as insomnia, depression or anxiety. An Israeli research team has now presented a promising prospective study with oncological patients.  The long-term study provides evidence for a reduction in the overall burden of cancer after therapy with medical cannabis. 

 

Structure of the cancer study 

The research group surveyed oncology patients over a total period of 2.5 years at various points in time with regard to individual pain perception, quality of sleep, sexual activity, depression and anxiety. At the beginning of the study, a total of 324 patients were involved, and the last survey was conducted with 126 individuals. The average age in the study group was 64 years, and women slightly outnumbered men, accounting for 59 percent. All participants suffered from advanced stage cancer (“Stage IV”). Breast, colon, lung and ovarian tumors were most prevalent. Therapy was with well-tolerated cannabis oils, the dosage of which was documented separately.    

Results 

The therapy with medicinal cannabis brought a significant improvement in almost all questioned aspects. The authors described the reduction in the overall burden of cancer symptoms after 6 months as particularly striking: The median decreased by 18 percent compared with baseline. Side effects were observed, but were not severe and remained stable during therapy.   

Reduction of pain symptoms, less analgesics needed 

Another interesting finding: treatment with medicinal cannabis led to a reduction in pain symptoms and less need for opiates, but also other painkillers such as non-steroidal analgesics as well as anticonvulsants or antidepressants.   

Significant improvements after 6 months of therapy 

Last but not least, the results of the study seem to indicate that the success of treatment with medical cannabis depends, among other things, on the duration of therapy. Therefore, the statistically significant changes in symptoms appeared only after 6 months of continuous intake of cannabinoids. In a previous study, the authors investigated the short-term effects of pharmaceutical cannabis therapy and found no significant improvements in cancer symptoms.

Each individual has a unique endocannabinoid system (ECS) tonus that reflects the level of ECS constituents. Both, too low and too high ECS tonus levels can lead to health problems and appear to be involved in the development and chronicity of diseases. Unfortunately, the connections are largely unknown in the medical community.   

We asked Robert Uhlenbrock, a Kalapa Clinic physician and expert in the use of medical cannabis, about the importance of ECS tonus.   

CanPharma: Mr. Uhlenbrock, what happens in the human body when the ECS tonus deviates from the norm (the average values)? 

 Currently, science assumes that, for example, a clinically relevant endocannabinoid deficiency leads to an imbalance in the body’s system. This imbalance seems to be involved in a number of chronic diseases. Several studies suggest a link between low ECS tonus and irritable bowel syndrome, migraine as well as fibromyalgia complaints [1]. Especially in the development of migraine, there is increasing evidence for an involvement of the endogenous endocannabinoid system [2].    

 What are the causes for a deficiency of endogenous cannabinoids and how can this knowledge be used therapeutically? 

 Low ECS tone can have both genetic causes and be influenced by a person’s individual health behavior. For example, if the human body produces too many enzymes that break down the body’s own endocannabinoids, the tone will be too low. Since endocannabinoids play a crucial role in human physiology, deficient ECS tone can be associated with individual complaints or manifest diseases. 

 This knowledge has therapeutic relevance: If, for example, the anandamide* level in the blood were examined at regular intervals, we would notice a clinically relevant imbalance at an early stage and be able to react. I am thinking here of the intake of exogenous – i.e. plant-based – cannabinoids, but also regulation via sport, stress reduction and a healthy diet. For the so-called lifestyle factors in particular, there are now promising studies that demonstrate a health-promoting effect [3].   

 CanPharma: Why is the ECS tonus hardly considered among physicians? 

 Knowledge of the body’s endocannabinoid system is not a topic of university teaching and is therefore hardly anchored in the professional world. Whoever asks treating physicians for a determination of the anandamide level will most likely encounter little knowledge. Furthermore, as far as I know, there is no laboratory that measures this parameter as part of a blood count. The therapeutic importance of ECS the tonus is significantly underestimated. This must change urgently!  

 * Anandamide, is the best known and scientifically first described endocannabinoid. It is one of the most important endocannabinoids for controlling the balance in our body, called homeostasis.

Elderly (geriatric) patients often suffer from chronic pain and are sensitive to opiates and other centrally acting substances. A retrospective evaluation from a medical practice shows: Medical cannabis – in this case dronabinol – can alleviate the symptoms of those affected.   

Study participants included all geriatric patients aged 80 and older who were treated in a pain medicine practice in Potsdam, Germany from the time the cannabis law came into effect in March 2017 until mid-July 2018. Group A consisted of geriatric, non-palliative pain patients, group B included geriatric palliative pain patients.   

Questionnaire with information on dosages and pain intensity  

 The basis for the retrospective monocentric cohort study was a questionnaire with information on pain intensity, dosage, effects and side effects of dronabinol therapy. The results are encouraging: 21 out of 40 patients whose data were analyzed achieved a pain reduction of more than 30 percent. Another ten percent even reported an improvement of more than half. According to the respondents, about four symptoms or side effects of the previous therapy were positively influenced.  

 The authors of the study conclude from the results that cannabis-based medicines represent an effective and low-risk therapy option for the treatment of geriatric pain and palliative patients. At the same time, they call for further clinical studies – especially on the indication spectrum of the substances.

Disturbed thinking, delusions and sometimes even hallucinations are all typical symptoms of a psychosis. That CBD can have an influence on the brains of people suffering from psychotic episodes has now been discovered by British researchers at King’s College using imaging techniques.  

A 19-member control group and 13 psychosis patients were participants in the double-blind study in England. Symptomatic subjects received their regular antipsychotic medication. Brain activity of all participants was monitored using magnetic resonance imaging (MRI) technology.  

 Normalization of activities in prefrontal and medio temporal brain areas  

 The symptomatic subjects received a placebo on individual days, and the researchers were able to determine deviating activities in the prefrontal and medio temporal brain areas compared to the control group. In addition, the hippocampus and striatum of the non-psychotic participants interacted less strongly. A brain activity similar to the healthy control group could be shown in the symptomatic group after the administration of 600mg CBD.  

Based on these findings, the authors of the study conclude that CBD is effective in treating psychotic symptoms. However, final conclusions cannot yet be drawn due to the small number of participants. There is also a lack of studies on the long-term effects of CBD consumption. Therefore, the researchers call for more extensive studies in connection with CBD and psychoses and other neuropsychiatric diseases.

Inhaling cannabidiol e-liquid has positive effects on the verbal episodic memory of young healthy people. This was recently found by a group of Swiss researchers in a placebo-controlled study. Thirty-four people with an average age of 22 and no previous illnesses were asked to memorize 15 unrelated nouns. They were then given a single dose of CBD (12.5 mg cannabidiol e-liquid) once and once a placebo to vaporize. After about 20 minutes, they were assessed on their verbal episodic memory.

CBD outperforms placebo

The result is clear: compared to the placebo, CBD improved the short-term memory performance. The Basel research group concludes that not only does CBD have no negative effect on basic cognitive functions, they also see further evidence of the interaction of the central endocannabinoid system with vaporized CBD. In conclusion, CBD may be able to positively influence memory processes and may have further therapeutic potential if appropriate.

To investigate optimal dose-response relationships, the neuroscientists from Switzerland recommend further extensive studies.

A group of U.S. scientists from Florida has made another leap forward in terms of the effectiveness of medical cannabis for chronic pain. Analysis of Real World Data showed improvement in anxiety/depression, sleep, and quality of life.  

The Florida research team examined data of 46 adults (half of which male/female, average age 55 years) who had started treatment with medical cannabis for chronic pain. A feature of the prospective study: The survey on the factors pain intensity, anxiety/depression, sleep and quality of life took place under so-called real-life conditions, i.e. the patients transmitted their data via smartphone directly from their natural environment to the scientists.    

In order to test the effectiveness of the medication, a baseline survey, an EMA (Ecological Momentary Assessment: diagnostic access to the behavior and experience of the subjects) was conducted after one or three weeks, as well as a follow-up survey after three months towards the end of the study.   

First effects already visible after a few weeks of therapy  

The results are clear: shortly after a few weeks of therapy, the self-reported data showed a significant reduction in momentary pain intensity and a similar increase in daily sleep duration.  

After three months, a significant change in the most severe pain as well as in the depressive experience of the patients was observed. In addition, an increase in sleep duration, an improvement in sleep quality, and an increase in quality of life were observed compared to the baseline survey.   

Florida is among the fastest growing markets for medical cannabis within the United States.

Good news for pharmacies and patients: CanPharma GmbH’s medicinal cannabis can now be purchased through pharmaceutical wholesalers. 

For the pharmaceutical company, the cooperation with the wholesaler is a step in the right direction: “We are pleased that we are expanding our distribution channels throughout Germany,” says Stefan Jacker, Managing Director of CanPharma GmbH, “this improves the direct availability of our pharmaceutical cannabis varieties and increases the service for pharmacies and patients.”   

CanPharma aims to provide seriously ill people with optimal treatment with medicinal cannabis and to supply pharmacies with standardised and high-quality products. A therapy with medicinal cannabis increases the quality of life in many chronic diseases such as cancer or multiple sclerosis.   

The company is currently planning to expand its product portfolio – primarily with products with a high CBD content. This will give CanPharma an even broader product range.

The pharmaceutical company CanPharma launched several discount contracts with statutory health insurance funds at the beginning of the year. The contract with the health insurance provider GWQ has been in effect since the beginning of January, and the cooperation with IKK Classic has been in place since February 1st. Further agreements with payers to improve the supply of medical cannabis are already planned. This makes CanPharma one of the first cannabis companies to conclude a discount contract.   

 According to CanPharma, discount contracts with medical cannabis aim to put the supply of patients with certain cannabis-based medicines on a secure footing and at the same time increase economic efficiency. In addition, the aim is to simplify the time-consuming reimbursement process: Currently, therapy with pharmaceutical cannabis requires approval by the health insurance fund before doctors are allowed to issue the corresponding prescriptions.   

Discount agreements are not uncommon for other medicines, but they are new for cannabis-based products. Stefan Jacker, pharmacist and managing director of CanPharma GmbH: “Cannabis-based pharmaceuticals have so far not had the status they deserve in the therapy of seriously ill people. We hope that the new agreements will lead to better acceptance of cannabis and to more trust within the medical profession. The cost-effectiveness of this adjunctive therapy option plays a role in this – and we are actively addressing the issue.”  In this context, an existing discount agreement with medicinal cannabis has no effect on the so-called therapeutic sovereignty: “No patient should be switched. What matters to us is that in a cannabis therapy, the products are prescribed that are on the one hand individually tailored to the patient’s therapy needs, and on the other hand economical and of course of the best pharmaceutical quality. The patient’s well-being has the highest priority for CanPharma,” emphasises Stefan Jacker.   

The discount contract between CanPharma and IKK Classic covers the prescription of three cannabis extracts. The agreement with GWQ goes a bit further and also provides for the prescription of cannabis flowers. GWQ is a health insurance provider that represents various statutory health insurance funds, such as numerous company health insurance funds.   

CanPharma GmbH has already been on the market since July 2020 with various prescription medicines such as medicinal cannabis flowers, and in May 2021 three different cannabis extracts were added.

In general, they do not have a particularly good reputation: Many amoebae contain bacteria that can cause diseases in humans. A group of researchers from the Leibniz Institute for Natural Product Research and Infection Biology in Jena has now managed to pull off a trick – they have made the amoeba Dictyostelium discoideum produce a precursor of the active ingredient in cannabis, tetrahydrocannabinol (THC).   

Amoebae are single-celled organisms and are capable of producing numerous natural substances. In the case of the genus Dictyostelium discoideum – a slime mould – these are various polyketides that can be used for a whole range of therapeutic applications. These include the cannabinoid precursor olivetolic acid. The principle of action of the single-celled organisms in this respect: they join together to form larger structures that can act like a multicellular organism. 

Reactivation of slime mould enzymes 

In the course of their research, the Jena working group first found that the slime moulds produced either resveratrol (a secondary plant substance to which, among other things, an anti-inflammatory effect is attributed) or olivetolic acid, depending on the experimental set-up. The catch: the synthesis only works if a special chemical additive is present in the nutrient medium. Beyond that, the amount produced is marginal.   

In the next step, the research team developed a way to combine the slime mould enzymes with an enzyme from the hemp plant. A hybrid construct is created that is inserted into the genetic material of Dictyostelium discoideum. As a result, the amoeba directly produces the required precursor – olivetolic acid is thus produced without further additives.   

Dictyostelium discoideum acts as a production platform 

In the next step, the research team wants to produce the end product THC directly in the amoebae by introducing two more missing enzymes into the single-celled organism. A patent for the biotechnological extraction of the plant substances has already been applied for. It is particularly promising because the chemical extraction of THC in its pure form is very time-consuming, expensive and associated with low yields. Microbes, on the other hand, can be cultivated en masse and thus theoretically produce large quantities of THC in a short time. The production is not dependent on the growth of a plant or the climatic conditions.
