And the pace of research is accelerating.<\/p>\n<p>Between 2018 and 2020, the number of papers mentioning cannabidiol (<span class=\"caps\">CBD<\/span>) nearly doubled from 788 to 1,408. And at the current rate, this year will see another large increase with approximately 1,800 papers referencing <span class=\"caps\">CBD<\/span> published.<\/p>\n<p>Include <span class=\"caps\">THC<\/span> and that projection balloons to nearly 2,600. Then there are the minor cannabinoids, the endocannabinoids, the cannabinoid receptors throughout the human body, and the many constituents of the broader \u201cendocannabidiome.\u201d It\u2019s enough to overwhelm even active researchers venturing beyond their niche in the rapidly expanding field of cannabinoid science \u2013 let alone consumers and health professionals.<\/p>\n<h2>Real-World <span class=\"caps\">CBD<\/span> Evidence<\/h2>\n<p>Relatively few of these papers describe studies conducted with human beings. Many present results from experiments in animals (typically rats, mice, or zebrafish), and some are even more theoretical and removed from the results with which we\u2019re most concerned, those pertaining to actual human health outcomes.<\/p>\n<aside class=\"pull-right\">\n<p>People with moderate or severe symptoms experienced less pain, anxiety, and depression, and greater wellbeing after three months of <span class=\"caps\">CBD<\/span> treatment.<\/p>\n<\/aside>\n<p>A new paper out of Canada caught our eye because it evaluated a range of outcomes among a large number of patients at a medical cannabis clinic in Quebec (279, to be exact) who had used both <span class=\"caps\">CBD<\/span> and <span class=\"caps\">THC<\/span> in the course of their daily lives over a period of up to six months.<\/p>\n<p>Published in the<em> Journal of Cannabis Research<\/em>, the paper includes some intriguing results \u2013 with the important caveat (common to all real-world or \u201cnaturalistic\u201d observational studies due to the lack of a control group) that a cause-effect relationship cannot be inferred.<\/p>\n<p>Compared to their scores at baseline, participants with moderate or severe symptoms reported experiencing considerably less pain, anxiety, and depression, and greater wellbeing, after three months of formal treatment. After six months, the improvements held relatively steady. However, these improvements were not seen in participants categorized as having only mild symptoms.<\/p>\n<p>Due to the subjective, self-reported nature of symptom assessment, the researchers note that findings may be biased by participants\u2019 positive expectation of treatment, which can lead to a placebo effect. But this doesn\u2019t explain why patients with moderate or severe symptoms would respond so much more than those with mild symptoms. \u201cThe results of this study contribute to address the myths and misinformation about <span class=\"caps\">CBD<\/span> treatment and demand further investigation,\u201d the authors conclude.<\/p>\n<h2>Better Together: Ketamine and <span class=\"caps\">CBD<\/span><\/h2>\n<p>Ketamine and <span class=\"caps\">CBD<\/span> both exert effects that are mediated by the endocannabinoid system. What happens when they are administered together?<\/p>\n<p>An anesthetic with dissociative and hallucinogenic effects, ketamine has of late been increasingly used as a remedy for major depressive disorder at numerous clinics in the <span class=\"caps\">US<\/span>. Scientists based in Brazil and Denmark wanted to ascertain whether <span class=\"caps\">CBD<\/span>, also known for its antidepressant properties, could reduce the unwanted psychostimulant side effects of ketamine.<\/p>\n<p>To find out, the researchers administered ketamine and <span class=\"caps\">CBD<\/span> to mice, both alone and in combination. Their results, reported in <em>Neuropharmacology<\/em>, indicate that <span class=\"caps\">CBD<\/span> maintained the desired antidepressant effect of ketamine (according to a behavioral model meant to approximate what we call \u201cdepression\u201d in humans), while attenuating ketamine\u2019s adverse stimulant effects (according to an animal model of \u201clocomotor activity\u201d).<\/p>\n<p>The authors stress that these findings will need to be replicated in other animal models. But they also point out there\u2019s good reason to believe they\u2019ll hold. We already know from both human and animal studies that <span class=\"caps\">CBD<\/span> can prevent some of the less desirable effects of other compounds, including cannabidiol\u2019s occasionally brash sibling, <span class=\"caps\">THC<\/span>.<\/p>\n<div class=\"callout\"><\/div>\n<h2>Intergenerational Effects of Omega-3\u2019s<\/h2>\n<p>Earlier this year, Project <span class=\"caps\">CBD<\/span> wrote about how the balance of omega-3 and omega-6 fatty acids in one\u2019s diet impacts overall health via the endocannabinoid system (<span class=\"caps\">ECS<\/span>). A recent report by researchers from Brazil, Italy, and Canada in the <em>Journal of Nutritional Biochemistry<\/em> presents evidence that advances our understanding of the link between these essential dietary compounds and the <span class=\"caps\">ECS<\/span>.<\/p>\n<aside class=\"pull-right\">\n<p>Changes in levels of endocannabinoids and cannabinoid receptors linked to dietary intake of omega-3 fatty acids can be passed from one generation to the next.<\/p>\n<\/aside>\n<p>Female rats were fed one of three different diets \u2013 high in omega-3, low in omega-3, or a control \u2013 15 days before mating and during pregnancy. Then the scientists analyzed the cerebral cortex and hippocampus of both mothers and offspring within a couple days of birth.<\/p>\n<p>Consistent with what would be expected, the researchers found reduced expression of the <span class=\"caps\">CB1<\/span> cannabinoid receptor and increased expression of the <span class=\"caps\">CB2<\/span> receptor in the mothers fed an omega-3-deficient diet. Interestingly, they also found the exact same thing in these mother rats\u2019 offspring.<\/p>\n<p>What\u2019s more, in the offspring of mothers fed supplemental omega-3, the researchers found increased levels of the omega-3-derived endocannabinoids <span class=\"caps\">DHEA<\/span> and <span class=\"caps\">EPEA<\/span> in both the hippocampus and the cerebral cortex, as well as reduced levels of the omega-6-derived endocannabinoid 2-<span class=\"caps\">AG<\/span> in the cerebral cortex.<\/p>\n<p>Together these findings demonstrate that changes to levels of endocannabinoids and cannabinoid receptors in the brain associated with dietary intake of omega-3 fatty acids are capable of being passed from one generation to the next \u2013 at least in rats. The study does not link these alterations to any specific health outcomes.<\/p>\n<div class=\"callout\"><img fetchpriority=\"high\" decoding=\"async\" typeof=\"foaf:Image\" class=\"img-responsive\" src=\"https:\/\/www.projectcbd.org\/sites\/projectcbd\/files\/styles\/related_content_popout\/public\/field\/image\/spray_pest_sq.png?itok=asVF5MRm\" width=\"670\" height=\"350\" alt=\"\" data-pagespeed-url-hash=\"75208777\" onload=\"pagespeed.CriticalImages.checkImageForCriticality(this);\"\/><\/div>\n<h2><span class=\"caps\">BPA<\/span>, Obesity, and the <span class=\"caps\">CB1<\/span> Receptor<\/h2>\n<p>Now on to zebrafish.
