CBD Revisited



BY DR. BAYNE FRENCH MD DC

CBD is cannabidiol. We’ll call it CBD because “cannabidiol” is a lot for a mountain fella from Eureka, Montana, to say, spell, or pronounce.

Let’s start with a review. What we’re talking about is cannabis. It’s all about cannabis. Cannabis is not a colloquialism or slang. It’s Latin and a genera of plant in the family Cannabaceae. Hemp is Middle English, referring to the same damn thing. Don’t ask me what “middle” means; I have enough trouble with “English.”

Carl Linnaeus, the Father of Taxonomy, was born on a glorious Swedish day in 1707. I know it was glorious because I nailed a giant Brown trout on a Green Weenie that very morning. Carl disappointed his parents by turning away from the priesthood, silly boy, and instead was interested in critters. Clever boy. Although I’m well versed in disappointing my parents, Carl came to understand redemption. His method of categorizing critters has remained durable. So when he puts cannabis as an entire genre, I listen.

But this is where it gets confusing. What about the species? We all know that species follow genus. Well, for cannabis, “species” is in quotations. There is ONE species called sativa. Cannabis sativa L. The L is for Mr. Linnaeus. There are, however, subtypes and subspecies that have been cultivated for various purposes. Are you with me?

So what is “marijuana”? It is a Mexican Spanish term and has no unified definition. It refers to cannabis.

No review would be complete without a discussion about our endocannabinoid system (ECS). Understanding that we each possess this microscopic system is important to view then how CBD and related compounds might benefit us.

The ECS consists of a couple of chemicals that we make in our body (AEA and 2-AG). These compounds interact with docking ports (receptors) on our cells and exert a variety of effects. Other similar compounds from plants also interact with these receptors. Many scientists feel that this system acts as a means of communication between virtually all the cells of our body and is involved in myriad processes involving pain, inflammation, mood, immune function, and metabolism.

So why do we possess this massively complicated signaling system? Because we’re vastly complicated and shaped by survivalistic (notice I didn’t say ‘evolutionary’) pressures. And we’ve interacted with this cannabis/hemp/marijuana/reefer/dope/grass/Mary Jane plant for a very, very long time, perhaps all starting in the Altai Mountains of Asia. Growing up I obsessed about the Altai Mountains, with its giant rams. And it’s awesome, Weed.

What point am I making? There is something interesting biologically going on here. We are perfectly suited to come into contact with cannabis and its compounds. There is biochemical evidence that favorable things thus occur.

What are those favorable things? Depends on who you talk to. I’m all about the Empiric Method… listening to people, making notes, remembering, observing. In this era of medical snobbery of evidence basis, the power of empiricism is understated. Dr. William Osler is among the most respected physicians of all time. He’s basically the GOAT but a lousy cribbage player. Dr. Osler lectured and wrote about the power of observation. This takes effort. Observation is calorically costly and takes time, which is why it has fallen out of favor. Well, I have an upraised lengthy middle digit for you dogmatic snobs who want to call me out for observing outcomes and writing about them. Debating with you is a waste of my precious single-parenting time.

What point am I making? Oh yes, something powerful occurs when we sapiens interact with the compounds within cannabis plants. There are over 100 cannabinoids. These chemicals are fats. Lipids. The two biggest players are CBD and THC. They are chemically similar but different enough to exert very different effects. THC is “psychoactive,” meaning it can create a high feeling. CBD can’t do this and isn’t happy about it.

That’s enough review because I’m bored. Let’s get to what these compounds can actually do for us. I’ve written about CBD before. I’m sure you remember because they were just so riveting. Is there new stuff? Surely, by now, there’s been a large-scale scale, double-blinded, placebo-controlled trial. Not really. There’s some new stuff, but it still comes down to what makes sense and who you trust. I’ll get back to the trust part later.

Psychosis

Know anyone with Schizophrenia? It’s poorly understood, and like most diseases, it’s nasty. Medical treatment since the 1950s has focused on the chemical dopamine. These medications don’t work well for some patients, and there are many side effects.

Henry Wellcome (yes, two l’s) was a pharmaceutical bigwig and a master croquet player, although I still feel that some of his moves were questionable. The Wellcome Trust was developed in the 1930s and is currently funding a large study through Oxford University. This study is the first of its kind involving 35 centers in Europe and North America.

Lead investigator Dr. McGuire: “Cannabidiol is one of the most promising new treatments for people with psychosis. This study will be the first to evaluate cannabidiol in large numbers of people with psychosis or psychotic symptoms and bring together many of the leading centers working in this area around the world”. Stay tuned.

Anxiety

I know that hardly anyone has stress and worry these days. Still, I want to go over an interesting and recent study on patients with anxiety that also evaluated cognitive (thinking) performance (Dahlgren et al. Communications Medicine. Nov 2022).

Traditional anxiety treatments are largely by prescription. Although these medications can be very effective, they are only available by prescription, may take up to 12 weeks to realize their full effect, and are commonly associated with troubling side effects.

This study was small (only 14 patients) and was “open-label,” meaning the patients and researchers knew they were getting a CBD-containing compound. A full-spectrum compound was administered under the tongue three times daily for 4 weeks. Each dose contained about 10mg of CBD and 0.23mg of THC. Being full-spectrum, all the other cannabinoids, terpenes, and flavonoids from cannabis were included in trace amounts.

Both anxiety and cognition were assessed by patient self-report and also by well-validated assessment tools. There were significant reductions in anxiety, starting as early as one week into treatment, and also improved cognitive abilities. The patients exhibited “significantly faster performance and fewer errors.” For a Eureka Montana mountain person, this seems better than more errors over a longer time.

The treatment was also extremely well tolerated. This study is ongoing with a double-blinded, placebo-controlled stage. This means both researchers and patients don’t know what they’re getting. There will also be a treatment arm comparing just CBD with a full-spectrum compound. Stay tuned.

COVID

No article would be complete without mention of COVID. This infection is very much with us, perhaps indefinitely, like influenza. Reportable death data from COVID is not without its controversies, but some researchers feel that as of mid-2022, COVID was responsible for killing 6.4 million sapiens.

Medical treatment for COVID can really trigger me. I can’t think of anything more pathetically dogmatic, emotional, and, well…human than this subject. Years ago, I compiled evidence on ivermectin as a medical treatment option in a multi-thousand-word article. A close family member turned on me like a rabid dog for it. The other day, the European Parliament approved ivermectin for COVID treatment and stated: “The drug ivermectin has undergone 99 studies on 137,000 patients run by 1,089 scientists with a success rate of 85 % in prophylaxis and 62 % in early treatment and has been officially approved for early treatment of COVID-19 in 28 countries. The few studies that find the drug to be ineffective often use doses that are either too large or too small. Besides ivermectin, there are other safe, effective, and cheap treatment protocols.

I like the sound of “safe, effective, and cheap”. Much of what we prescribe routinely is not that. Could it be that CBD helps with COVID treatment too? Let’s look. The main concept here is targeting and minimizing the inflammatory caldron that the viral infection triggers. Much of the mortality (dying) and morbidity (suffering) is a result of the hyper-zealous immune response. This is why steroids offer treatment benefits.

Holst et al. (Cannabis and Cannabidiol Research. 2022) published a review article looking at 9 studies. Most of these studies were in vitro, meaning they were done in a laboratory setting, not on living critters (human or animal). “Inflammatory infiltration of the lungs, as well as reduced protein exudation, inflammatory cytokine levels, and myeloperoxidase levels, were observed in response to CBD.” This is all favorable.

Fernandes et al. (Life Sciences. 2022) published a study reporting that CBD offered favorable immune system actions on COVID-infected cells. CBD helped promote apoptosis (cellular death) of these infected cells, allowing them to be removed sooner, thus minimizing the virus’s ability to spread. CBD also bolstered the immune response efficiency by other pathways. The authors state: “CBD may prime components of the innate immune system and enhance the preparedness of the cells to fight RNA-type viral infection…” and “Therefore, in the future, this compound could be considered a potential therapeutic agent …”

One more, stay with me. Vallee et al. (Frontiers in Immunology. 2022) published a study identifying two different modes of action that CBD had to reduce the hyper-inflammation associated with COVID infection. The authors state: “Taken together, it has been hypothesized in the study that cannabidiol can be used clinically to prevent hyperinflammation and lung tissue damage in COVID-19 patients.”

Heart Disease

This condition is what most people die of. It is vastly complicated, multi-factorial, and, like most diseases, a combination of environmental/lifestyle factors with a genetic propensity. What is clear is that there are numerous inflammatory pathways involved in the development of arterial disease leading to heart attacks.

Ayala et al. (American College of Cardiology. 2022) performed a systematic search of a huge literature database called PubMed. Nine studies were included. All nine were “preclinical,” meaning they were not done on humans because “no quality randomized control trials (RCTs) for the use of CBD in acute or chronic coronary syndromes were found.”

Compiled data was “robust” and “promising” in CBD-mediated mechanisms to reduce oxidative stress, inflammation, and experimental models of heart attacks.

More on Inflammation

Some specific anti-inflammatory pathways of cannabinoids have been previously determined and mentioned in regards to COVID. Peltner et al. (Cell Chemical. 2023) performed anti-inflammatory experiments in a laboratory setting. It was found that CBD activated an enzyme called 15-lipoxygenase-1. Activation of this enzyme triggered the production of numerous substances responsible for causing inflammation to subside. “CBD thus induces a switch in the affected cells, so to speak, which steers the inflammatory process from the promoting to the inhibiting side.”

The researchers were able to confirm their laboratory findings by further study in live mice.

Smoking

One in five people in the US who die every year do so from a smoking-related cause. It is a potent driver of heart disease and dozens of cancers. Curbing cravings is paramount in helping patients stop smoking or, at the very least, reduce intake. There are prescription medications that are effective and not without side effects. There are also numerous over-the-counter nicotine delivery systems that are not without risk.

Nasrin et al. (Toxicology. 2023) at Washington State University performed a laboratory-based study on CBD’s effect on nicotine metabolism. The majority of inhaled nicotine is metabolized (broken down) by one enzyme protein called CYP2A6. Why they couldn’t name it something fun like Pinecone or Squitchy is beyond me. It turns out that CBD knocks the crap out of Squitchy. “The impact of CBD on this particular enzyme appeared quite strong, inhibiting its activity by 50%...”

So who cares? Well, nicotine-addicted folks might because this action could allow them to wait longer between cigarettes, thus reducing harm. Again, this data is pre-clinical. It was not a study on humans. WSU is, however, developing a clinical study on actual human smokers. Stay tuned.

Athletes

Let’s look at a cute little study from earlier this year. This was a clinical study, meaning it was done on actual humans—ex-elite athletes, in fact, like me.

Hall et al. (J Cannabis Res. March 2023) were seemingly the first to study CBD treatment in high-level athletes. Twenty athletes who played professional US football, track and field, and basketball were recruited. They all had lower extremity injuries. All rehab was stopped, and each athlete used 10 mg twice daily of a topical CBD formulation for their respective injury.

The authors reported: “There was a significant improvement in self-reported pain levels and pain-related disability, including family and home responsibilities, life support activities, occupational activities, recreational activities, self-care, sexual function, and social activities.”

There are numerous limitations of this study. It had a very small sample size and was open-label (the subjects knew what they were getting); the CBD, although the main ingredient, was combined with other compounds; and the outcomes were self-reported, not actually measured or examined. The authors did feel that the data was positive enough to recommend randomized and controlled studies of elite athletes. Like me.

Zebrafish

Here’s another cute study. Why Zebrafish? They were probably on sale.

These cute little fellas were divided into groups and fed different concoctions. Some got CBD, other lucky ones got THC; some ate aluminum, and others CBD and THC with aluminum. Here’s a news flash, aluminum is toxic. We use it in cosmetics, pharmaceuticals, vaccines, cooking utensils, etc., and it kills nerve cells.

The behavior of these fish was observed, like how much they swam, socialized, and explored. Also, levels of chemicals were sampled from the fish. It was found that aluminum was toxic to the nervous system of these fish. Shocking, I know. It was also found that both CBD and THC were protective and actually allowed the aluminum-toxic fish to re-establish their normal behavior, like exploring the confines of their fake ecosystem, biting the fins off others, avoiding getting their fins bitten, and making more Zebrafish, which is pretty much the same thing we’re all doing.

Obesity

The last study I’ll include is on the disease of Obesity. This condition represents a pandemic without rival and one without global or even national leadership. Furthermore, there is a large-scale promotion of this disease by the government and industry. The Food Pyramid alone is probably responsible for tens of millions of deaths.

All potentially effective treatment modalities need to be considered. You guessed it, CBD has shown efficacy on physical measures of obesity.

Reis et al. (Int J Obes. 2023) looked at 2,620 randomized controlled trials evaluating the use of cannabis and various measures of obesity in adults. Of these trials, only 12 were found acceptable for a meta-analysis that included 4,394 patients.

When these studies were pooled, it was clear that the use of cannabis was associated with reduced waist circumference, body weight, and body mass index (BMI). The patients who were followed longer showed the largest reductions, indicating an ongoing and durable therapeutic benefit.

Trust

A South African study (Mouton et al. Phytomedicine. 2023) used high-performance liquid chromatography (HPLC) to look at 16 different CBD-containing products. I really don’t know what HPLC is, but it rolls off my tongue. Only 3 of the 16 CBD products actually contained what was labeled. Meaning that 13 companies were either lying or made egregious mistakes. “This information indicates a significant lapse in quality control measures.”

I’m not done. Johns Hopkins is a literal dude. Not John, but Johns. He was a philanthropist, meaning he had tons of money. He had 10 siblings too. Show-off, I’m stuck with one crazy sister. Compliments of Mr. Hopkins a study in 2022 (Spindle et al. JAMA Network Open. 2022) was done that tested over 100 CBD-containing products. Only 89 listed the total amount of CBD in mg on the label. Of those, only a few contained the actual amount labeled.

There are many other studies that really bring into question the quality and purity of what you think you’re purchasing and consuming.

Conclusion

If CBD were an athlete, it would be an obstacle course racer. It is so eclectic, capable, and able to act on so many different tissues. As a result, there is evidence of it helping with myriad conditions, symptoms, and diseases.

As discussed in the Trust section above, knowing your supplier is important.

CBD can provide a powerful adjunct to other healthful behaviors like proper eating, good cardiopulmonary fitness, restorative sleep, and other supplements. With all things involving our health, there is no time to wait. Disease prevention favors the proactive…those that think, educate themselves, and employ the assistance of metabolically favorable substances.

Thanks for the excellent overview. I’ve been using Hammer CBD and REM Caps for quite a while to help with sleep. Definitely improved my sleep quality. I was a seriously restless sleeper and often had insomnia. Now, I get a decent night’s sleep regularly and even enjoy a nap every afternoon!
