CB1 and CB2 receptors play differential roles in early zebrafish locomotor development

Scientists found that blocking CB1 receptors and CB2-receptors in young zebrafish resulted in morphological deficits, reductions in heart rate, and non-inflated swim bladders. These findings indicate that the endocannabinoid system is pivotal to the development of the locomotor system in zebrafish, and that disturbances to the endocannabinoid system in early life may have detrimental effects.

The translation of these effects to humans is obviously not direct, but it is important for science to learn about safety and expected effects, to examine how chemistry interacts in petri dishes, how basic organic/animal functions are impacted in a living thing, and when the time is appropriate, to then assess any effects in humans

The Endocannabinoid System’s Effect on the Cerebellum is a Drawback for Anti-Inflammatory Meds

Title: Monoacylglycerol lipase blockade impairs fine motor coordination and triggers cerebellar neuroinflammation through cyclooxygenase-2

Researchers are constantly considering how cannabis may impact the human brain, for better or worse. A recently published work points out a negative effect on the cerebellum, caused by the inhibition of the main enzyme that is used to break down the endocannabinoid “2- arachidonoylglycerol” (2-AG). By inhibiting the degradation of 2-AG, more of the endocannabinoid is allowed to remain in, and act upon, the human nervous system. This abundance of 2-AG results in reduced synthesis of prostaglandins, which produces an anti-inflammatory effect.

Unfortunately, the abundance of 2-AG also results in motor coordination deficits related to the effect on the cerebellum, but the addition of a cyclooxygenase-2 (COX-2) inhibitor (commonly found in many over-the-counter anti-inflammatory medications) reverses these cerebellar deficits. 

This highlights the far-reaching capabilities of the endocannabinoid system and at least one powerful angle where researchers could develop medications to indirectly impact the endocannabinoid system. Cannabinoids are still a politically hot topic, but synthesizing drugs that alter the level of endogenous cannabinoids available in the body is an ideal way to study the endocannabinoid system and its therapeutic benefits, without engaging with the red tape that surrounds cannabis. The receptors mechanisms for the endocannabinoid system certainly warrants further investigation.

Cannabinoids and autoimmune diseases: A systematic review (Diabetes)

As it stands, there is no cure for Type 1 Diabetes Mellitus. But, some of us in the medical community are starting to wonder if cannabis could be a viable treatment option. Several studies already address this, with impressive findings, and now, A new mouse model study suggests that not only could CBD prevent Type 1 Diabetes, but it seems to also reduce symptoms after onset. 

Now researchers must determine the long term effects of CBD treatment. Watch a video summary below:

The Endocannabinoid System May Play a Role in Autism Spectrum Disorders

Title: CB1 receptor antagonism in capuchin monkeys alters social interaction and aversive memory extinction

A recent study has revealed that the dysregulation of the endocannabinoid system may play a role in autism spectrum disorders (ASD). Using non-human primates, researchers were able to mimic some of the social impairment seen in autism models by antagonizing cannabinoid 1 receptors with synthetic cannabinoids. Future research may continue to show links between ASD and the endocannabinoid system, suggesting that cannabinoids may be used to treat the social impairments characteristic in ASD. 


This research highlights how the endocannabinoid system may provide novel targets for developing therapies for what have seemed, previously, to be treatment-resistant disorders. Autism is still not well-understood and has many false beliefs associated with it. By studying the possible role of the endocannabinoid systems in ASD, researchers may be able to shed light on the mechanism(s) underlining the disorders and develop targeted treatments that allow patients a degree of greater control over the symptoms.

Video: The Endocannabinoid System’s Intriguing Role in Gut Health

A 2018 literature review summarizes the findings on cannabis and gut health. The endocannabinoid system plays a key role in gut motility, obesity, and inflammatory bowel disease (IBD). Targeting the endocannabinoid system with CBD oil or other cannabinoids seems to reduce colonic inflammation and relieve stress, at a microscopic level, inside the gastrointestinal tract. Watch our video adaptation of the effects of cannabis on IBD:

Honey and Garlic Help Heal Burn Wounds

Euphorbia honey and garlic- Biological activity and burn wound recovery

A recent study has shown that a combination of euphorbia honey and garlic can help heal burn wounds. Euphorbia honey and garlic have antioxidant, microbial, and healing properties that have now been confirmed to be effective when treating wounds resulting from exposure to extreme heat. Combining natural ingredients has been common in traditional medicine for years, but now western medicine is beginning to look at more natural compounds to aid in recovery and treatment methods.

A selective CB2 agonist protects against the inflammatory response and joint destruction in collagen-induced arthritis mice

In a study of 40 mice, scientists find that the CB2-selective agonist significantly reduced the severity of arthritis and markedly reduced bone erosion. These data clearly indicate that the CB2-selective agonist may be considered a novel treatment for rheumatoid arthritis.
