Recent Study Reveals Natural Method for Improved Crop Growth (Microbiome!)

Plant-derived coumarins shape the composition of an Arabidopsis synthetic root microbiome

In Summary:

While investigating plant molecules that inhibit parasitic growth, researchers have uncovered a new method for improving crop growth and overall yield. Small molecules, such as flavonoids and coumarins, improve the microbiome of plant roots in order to help them grow and maintain their health. While investigating how the absence of coumarins and flavonoids affect the growth of a common weed the authors stumbled upon a molecular mechanism that will facilitate efforts to grow crops in iron-deficient soils.

Dr. Caplan and the #MDTake:

The natural machinery of Cannabis supports the production of tremendous numbers of flavonoids, coumarins, and microbiome-supporting compounds. Over millennia, cannabis has evolved fastidious attention to detail, and an integral role in the animal ecosystem. Although this natural role has historically been disagreeable to many oppressive movements (religious and cultural), it is nonetheless, self-evident as modern society returns to embrace the science of cannabis. The scientific, medical, textile, farming, nutrition, recreational, and materials construction industries are all wishing only that they had come back to cannabis sooner.

Veterans Using Cannabis Medicinally More Likely to have PTSD than Recreational Users

Title: Medicinal versus Recreational Cannabis Use among Returning Veterans

In Summary:

A recent study found significant mental and physical health differences between veterans who use cannabis that they label as “medicinal” use versus those who prefer to label their use as “recreational.” Veterans who feel that they are self-medicating with cannabis, in what they believe fits more closely with a “medical” label are five times more likely to suffer from post-traumatic stress disorder (PTSD), nearly four times more likely to suffer from Major Depressive Disorder, and are more likely to experience Insomnia, or trouble sleeping. Furthermore, a majority of veterans medicating with cannabis suffer from conditions that qualify them to receive a medical marijuana registration card. Even so, they tend to refrain from discussing their interest in access with their doctors, out of fear of losing their valuable VA benefits.

Dr. Caplan and the #MDTake:

Over the years, countless veterans have valiantly and courageously dedicated themselves to missions of support for their fellow men, women, and country. In preparation, training, service, battle, leadership, education, and so many other ways, veterans have given back to their culture in a way few others can. The understanding that they may be shunned by their culture for seeking help, related to the suffering they may have experienced while serving their country, is unconscionable. It is shameful that the government and military have not appreciated and supported the easy opportunity to give back to our veterans, and it is long overdue that the culture gives back to those who have given a piece of themselves so that others may share the liberties they have served to uphold.

Pre-clinical Evidence for Analgesic Effects of Cannabis Doesn’t Match Human Trial Results

Current evidence of cannabinoid-based analgesia obtained in preclinical and human experimental settings

In Summary:

Pre-clinical animal models of pain provide a wealth of data supporting the pain-relief capabilities of cannabis; however, reproducing this data in human clinical trials has proved difficult. Data from the animal pre-clinical trials point to cannabinoids reducing stress responses and pain-evoked stress, desensitizing pain receptors, and increased pain sensitivity in animals that lack cannabinoid receptors. However, human trials present conflicting results: several studies have shown dose-dependent relationships, and in the current review this was experienced by many participants, wherein lower and medium doses provided pain relief, but higher doses triggered increased sensitivity to pain. Controlled studies may show a lack of impressive pain relief effects, personal reports of pain relief associated with cannabis use are nearly universal in retrospective reports. This suggests that there may be an important effect on well-being or mood, rather merely sensory pain. Furthermore, the relieving effects of cannabis appear to impact men and women differently.

Dr. Caplan and the #MDTake:

Additionally, much of pain relief is subjective, in both sensation, description, and inside the study environment. The description of pain varies from person to person, and researchers may be asking the wrong questions to the right people or the right questions to the wrong people. In fact, a growing perspective is that this mismatch may be more common and more pronounced than previously recognized. The makeup of pain is also quite complicated. For instance, a limb might hurt, but if there is swelling or tenderness nearby, those may amplify the discomfort. How can we take the full picture into account in the form of helpful data points? What of the emotional or psychological impacts of pain? Is it even possible that such things can be fully understood, let alone measured reliably? Assuming that emotional phenomenon or stress/suffering can be conveyed to research scientists, how can we ever hope to compare one person’s experience to another’s? For example, one would imagine that frustration associated with the pain experienced by a venerable world war veteran, who has previously endured tremendous and complex pains and associated psychological trauma may be quite different from someone who has never experienced a particular pain before.

Many Chronic Pain-Related Cannabis Studies Lack “High-Quality” Evidence

Cannabis-based medicines for chronic neuropathic pain in adults (Review)

In Summary:

In a recent Cochrane meta-analysis of studies investigating the use of medical cannabis for chronic neuropathic pain management, the authors determined that no results were what they could consider “high quality.” All data which related to degrees of pain relief, adverse events, and “Patient Global Impression of Change” were largely of very low or low quality, with some outcomes being of moderate quality. The meta-analysis concluded that no existing evidence backs up the use of cannabis for chronic neuropathic pain; however, the quality of evidence examined highlights the need for more controlled studies.  

Dr. Caplan and the #MDTake:

Depending on the system of organization one prefers, pain can be divided up into different subtypes. For one system, it’s three subtypes: neuropathic, nociceptive, and “other.” For another system, pain can be organized by timing (sharp, acute, chronic, breakthrough), location (bone, soft tissue, nerve, referred, phantom), or by the relative system (emotional, cancer, body.) This review discusses the subtype category of “neuropathic pain” as a means of grouping pain to study. The measures used to assess the pain are as subjective as the categories themselves. Clearly, compounding the two subjective divisions is unlikely to produce “high quality” data, but it is a misleading interpretation to take away that there is no good quality information to glean from the observations this review organizes, and also a misinterpretation to jump to an idea that cannabis is not helpful. Rather, given the statistical tools we currently use, and the subjective systems of understanding pain are not well-matched to translating the effects of cannabis on pain into this type of data.

Adolescent Cannabis Use Linked to Sleep Disturbances

Sleep Disturbances, Psychosocial Difficulties and Health Risk Behavior

Summary info:

A Dutch study investigated sleep disturbances in adolescents. Sleep disruption was linked to cannabis use, psychosocial difficulties, health risk behavior, and increased suicidality. Additionally, gender disparity in results suggests that girls may be more susceptible to sleep disturbances than boys , a result consistent with past recognition of some gender discrepancies in cannabis activity. These results highlight the importance of discouraging haphazard cannabis use, during adolescence, and the need for further gender-focused research surrounding sleep habits and cannabis use.

Dr Caplan, CED Foundation, and the #MDTake:

There are a few important issues that converge in this review. Generally, the question of adolescents’ use, (as an alternative way of describing the question of effects on a developing brain.) Also, this paper raises valuable questions about how cannabis may be interacting with sleep hygiene, for better or for worse. Psychosocial impact and risky behaviors are very complex topics to engage, even with a fairly large population sample of (n=16,781.) There are lots of intercorrelated topics assessed, analyzed, and discussed in the review, and it is all-too-easy to want to find causal patterns that are not apparent, again for better or worse, unless one chooses to construe the results or interpretation with causation in mind. Realistically, it is very likely to find overlap in a population of adolescents who have psychosocial difficulties, engage in risky behaviors, have increased risk of suicidality, and consume cannabis. To point to one of the components, arbitrarily, as the primary cause of the others is to unnecessarily and unjustly oversimplify a complex set of circumstances. The essential tenet, different genders seem to react differently with cannabis, is an excellent take-away, and also that we have much more still to learn.
