Journal Club with Dr. Jonathan Cachat: Recent Episodes
Kratom Science
Dr. Jonathan Cachat joins Kratom Science Podcast host Brian Gallagher to talk about kratom research. Each episode we pick a study about kratom published in a peer-reviewed journal.
For a special 40th episode, Dr. Jon revisits research he led out of Tulane University in 2010 on psychoactive substance effects in zebrafish. Out of 40+ published papers from this research, we look at one focusing on zebrafish symptoms when in withdrawal from ethanol, diazepam, morphine and caffeine. We also talk about living in New Orleans, the process of obtaining a DEA license, why caffeine was surprisingly highly toxic on fish, a popular film on substance use in the animal kingdom, and the upcoming event at the Cannabis Museum in Athens, Ohio on Sat. April 22nd: Community Hemp Fair. https://www.instagram.com/p/Cp0kkZ4u0yo/

Dr. Jon Cachat and Brian look at a survey conducted from 2019-2020. The survey found the majority of the 2,296 respondents with psychiatric conditions reported improvement in their condition following the consumption of kratom. Recently published by the American Psychological Association, the survey was authored by five past Kratom Science Podcast guests: Drs. Oliver Grundmann, Kirsten Smith, Darshan Singh, Zach Walsh, and Marc Swogger.

Thailand has recently decriminalized kratom after 79 years of prohibition. In today's episode of Kratom Science Journal Club, Dr. Cachat and Brian look at a study funded in part by the Thai government that analyzed kratom trees growing in various regions of Thailand. The team measured mitragynine levels, accounting for variables in climate such as light, temperature, humidity, and soil moisture. This information will be used to standardize a kratom product for future agriculture. In years to come, Thailand is set to be be a major exporter of kratom to the west, competing with Indonesia, where 95% of kratom imported into the United States comes from.

Dr. Jon starts off talking about the art show that took place in October 2022 at the new Cannabis Museum in Athens Ohio. Then we cover a study out of Thailand on kratom's effects on alpha-glucosidase and lipase, enzymes that are inhibited by medications for the treatment of diabetes. We see how kratom and mitragynine compare to standard prescription medications, and talk about the traditional use and possible advantages and disadvantages of developing mitragynine into a diabetes treatment drug in the future.

Dr. Jon and Brian look at a study (Farkas et al., 2022 https://doi.org/10.1016/j.ibneur.2022.08.007) in mice out of Temple University exploring whether mitragynine can help attenuate chemotherapy-induced peripheral neuropathic (CIPN). The team used oxaliplatin, a chemotherapy drug, to induce this condition in an equal number of male and female mice. Mitragynine was also combined with four receptor agonists to reveal the compound's uniqueness - it's activity at not only opioid, but adrenergic receptors accounts for the analgesic effects of kratom's most abundant alkaloid.
We also talk about a company who filed a patent for a "deuterated" form of 7-hydroxymitragynine and whether that poses signficant risks.
Plus, Dr. Jon announces the first event being held at the new Cannabis Museum in Athens, Ohio. "The Cannabis Museum Gallery is presenting a special collection of psychedelic and visionary art for sale. From art nouveau to counterculture, the poster has chronicled the evolution of society. Beginning in San Francisco before the 'Summer of Love' a new genre of advertising art and graphics evolved into a movement. This art documents our time and has transcended the zeitgeist for future generations. The show features art created for the Grateful Dead and other performers. Artists include Stanley Mouse, Rick Griffin, Alex Grey, and many others. It includes artist-signed posters and original paintings. Join us Friday, October 14. For a night of Psychedelic Art and Refreshments. Doors open from 4:20 to 8 pm at the Cannabis Museum. 16050 Canaanville Road, Athens, Ohio 45701. Proceeds of all sales benefit the Cannabis Museum.

Dr. Jon and Brian explore a study out of Thailand where goats meat goats ate feed supplemented with dried kratom leaves. What effect did this have on the goats body weight, cholesterol, blood, and feed conversion ratio? Even if it does work, will farmers be able to afford kratom as a feed supplement, given the newly legal market in Thailand?
Also we look at a case of serotonin syndrome after a 63 year old man on multiple medications introduced kratom without consulting his doctor. Then we talk about Tom Segura and kratom.

Dr. Jon and Brian take a break from kratom to look at the recently released Netflix documentary series hosted by Michael Pollan, How to Change Your Mind.
In related good news: the DEA backed off its decision to schedule five psychedelics. Hamilton Morris tweets. "Today the DEA withdrew their plan to prohibit DiPT, 4-HO-DiPT, 5-MeO-MiPT, 5-MeO-DET, and 5-MeO-αMT. As opposition mounted, they decided to cancel the hearing. Kratom was the first time public opposition prevented the prohibition of a substance, now we have five more successes!" https://twitter.com/HamiltonMorris/status/1550593819086929921

Dr. Cachat and Brian look at a letter (Smith et al, 2022) authored by former Kratom Science Podcast guests Dr. Kirsten Smith, Dr. Oliver Grundmann, Dr. Chris McCurdy, Dr. Darshan Singh, and other experts in the kratom field. The letter questions a systematic review (Broyan et al, 2022) of kratom case reports that offers buprenorphine as a solution to "kratom use disorder". Kratom-related case reports typically originate with patients showing up to emergency rooms and physicians' offices with symptoms. In these case reports, kratom product samples are rarely if ever tested for adulterants or contamination. The strength of the kratom product and dose levels seem to nearly always go unreported or wildly misreported (for example, the Broyan et al. review the Smith et al. letter addresses here claims the patients consumed an average of 92 grams of kratom per day). Furthermore, history or current use of other drugs is often overlooked.
Dr. Jon also talks about his trouble getting public data on cannabis testing and use trends from the State of Ohio's Marijuana Enforcement Tracking Reporting & Compliance (METRC) program.

Today on Journal Club, Dr. Jon Cachat look at a study in 2021 out of University of Colorado, Boulder in cooperation with Leafly that examines nearly 90,000 cannabis samples. Does Indica, Sativa, and Hybrid really mean anything in terms of psychoactive effects? Are cannabis strains labelled consistently in terms of cannabinoid and terpene content? We also talk about an app Dr. Jon is working on where users report effects of different brands of cannabis matched with cannabinoids and terpenes, called The Cannabis Diary. Plus we talk briefly about a Spanish company, KREI, that is working on a patent for genetically tracking cannabis strains to their origin.

Perhaps the most important paper Dr. Jon and Brian have covered so far, "Understanding Kratom: A Guide for Healthcare Providers" is a comprehensive introduction to kratom for those who provide direct care to kratom consumers, such as physicians or mental health specialists. In this paper spearheaded by past Kratom Science Podcast guest, Dr. Marc Swogger, reasons are listed for why people use kratom, what the possible risks and side effects are, and the damaging effects of drug hysteria and over-emphases in the medical literature on rare adverse events. Physicians then given recommendations for best practices, and urged to foster honesty by adopting a "non-stigmatizing and respectful" stance toward the patient. We consider this guide to be an important step toward eliminating one barrier to healthcare access, and to one day when every kratom consumer may say to their doctor, without fear of retribution, "I consume kratom".

This week we look at very interesting study led by Fredric Schiffer based on this theory of Dual Brain Psychology (DBP). DBP "posits that one brain hemisphere tends to be relatively mature and healthy, while the other hemisphere may be more affected by past traumas and supports a personality that is more prone to immature and/or destructive beliefs and/or behaviors" (Schiffer, et al, 2020). Using a form of light therapy called transcranial photobiomodulation (t-PBM), where beams of Near Infrared Radiation light is carried at specific points over the scalp, in this study and others Schiffer has shown a significant lowering of opioid cravings in many of the test subjects.

REPOST info: Yesterday I accidentally posted last week's episode with this week's information. I corrected this mistake 45 minutes after posting. Since the change is reflected on some listening apps and not others, I'm posting the episode again. Sorry!
For #29 of Kratom Science Journal Club, JC and Brian look at a 2019 report on toxicological events having to do with mitragynine. Does mitragynine increase the effects of other drugs? How toxic is kratom on its own? Other alkaloids have commonly been counted as mitragynine, so what are the ramifications? All this and other “medicolegal” issues.
Plus, we talk about the Cannabis Museum in Athens Ohio. When will it open? Probably not on 4/20, but close enough.

Dr. Cachat and host Brian Gallagher look at a groundbreaking study from University of Florida School of Pharmacy showing mitragynine has pain relieving effects independent of its metabolism into 7-hydroxymitragynine. This could be revolutionary in the study of kratom as a safer pain medicine. We go on to talk about the cannabis testing lab that Dr. Cachat is helping to develop in Columbus, Ohio, the phenomenon of "THC inflation" and "lab shopping", and what kratom alkaloid testing labs might look like in the future. We also talk about a recent article on cannabis compounds and SARS viruses.

Spoiler alert: kinda, but its more the quercetin in kratom, which is available in many food plants and as a dietary supplement on its own.
This study comes to us from a team at Universitas Nahdlatul Ulama Surabaya (UNUSA) in Surabaya, Indonesia, on the island of Java, south of the island of Kalimantan, where most of the kratom sold in the United States is grown. In this in vitro study, researchers applied a methanol extract of kratom to analogues of e-coli and Streptococcus pneumoniae, a bacteria that causes pneumonia, meningitis, and sepsis. The kratom extract has been shown to eliminate the bacteria in both samples, however this may not be due to properties unique to kratom itself.
Plus, Brian checks on the sources for yet another claim in the introduction to this paper that kratom is "smoked", and we talk about false claims about kratom's healing properties at the beginning of COVID.

Dr. JC and Brian look at a study out of University of Science, Malaysia. The comprehensive and detailed study in mice from University of Science, Malaysia revealed mitragynine in very high doses is an agonist (binds to and activates) cannabinoid receptor Type 1 (CB1). Mice administered with high-dose mitragynine demonstrated similar reward-seeking behavior and cognitive impairment as mice administered with morphine and THC. Mice that received high-dose mitragynine, morphine, and THC with a CB1 antagonist (a compound that binds to a deactivates the CB1 receptor), did not exhibit similar cognitive impairment, nor did mice that received low-dose mitragynine.

Dr. Jon Cachat and host Brian Gallagher look at a study that examined dopamine levels with an electrochemical sensor in rats administered with various levels of mitragynine. Dopamine release was detected as significant levels after a high dose of mitragynine after 4 days. Questions explored in this episode include: Does this accurately measure the kratom experience, since an isolated alkaloid is not the same as the entourage effect of several alkaloids in kratom? Since many of the alkaloids produce effects only after being metabolized, does kratom as a whole effect dopamine differently? Is this the proper use of the term "addiction" when the study seems to be about physical dependence?

Dr. Jonathan Cachat and host Brian Gallagher look at a case report of a supposed kratom-induced psychosis out of a student team from West Virginia University School of Medicine Department of Psychiatry, advised by MDs Alexander Muacevic and John R Adler.
A 43 year old man combat veteran with six tours of duty, traumatic brain injury, adrenal insufficiency, and post-traumatic stress disorder arrives at the ER with signs of psychosis. Prior to this, he hadn't slept in a week and ceased all medications including adderall, hormone pills, an antidepressant, and a weekly testosterone injection. He'd also been taking powder kratom and had ingested a bottle of liquid extract a week prior to going to the hospital. Could kratom have actually induced psychosis given all these elements combined, including prolonged insomnia? Could kratom have even contributed to his condition? If not, why does kratom get the headline? We look at the meat of the report, Dr. Jon goes off on why eye-catching titles for case reports can be damaging to science, and during the recording Brian finds another article about "Kratom-Induced Seizures", by a team of medical students, advised by the same two doctors as the original report, Alexander Muacevic and John R Adler.

Today Dr. Jon and Brian look at a study from University of Science in Malaysia, testing whether kratom alkaloids can be "chemosensitizers", in other words, help chemotherapy drugs in killing or slowing the proliferation of cancer cells. In this in vitro study on cancer cell lines, researchers found that a combination of the kratom alkaloids mitragynine and speciociliatine helped the chemo drug cisplatin in slowing and killing throat cancer cells. The research also showed that any combination of kratom alkaloids does NOT slow or kill cancer cells on its own. Plus, Dr. Jon talks about the latest on cancer and cannabis/cannabinoids. We end with talking about the HHS comment period and potential international controls on kratom in the future.

Neuroscientist Dr. Jon Cachat and host Brian Gallagher look at a study from University of Science in Malaysia that studies kratom extracts using various solvents: water, methanol, ethanol, and ethyl acetate. The technique they use, accelerated solvent extracting, uses less time and a lower amount of solvent for a safer and more environmentally friendly extraction technique. This technique has been established in botanical extractions, but is not commonly used for commercial kratom extracts. Some large kratom suppliers have been accused of outsourcing their extractions to China, and products come back containing toxic levels of residual solvents like chloroform and methanol, which could have serious health consequences. Further discussion is included on regulation of extracts, the benefits of extracts, the availability of full spectrum extracts (vs. extracts containing a single or only a few alkaloids), and how a kratom ban would exacerbate risks and dangers of contamination and adulteration especially in extract products.

For #21 Brian and Dr. Jon Cachat look at a study of polysubstance users in Kentucky, most of whom were either currently incarcerated or had been incarcerated in the 7 years prior to the research. The study examines substance use trends of this sample of about 500 volunteers, licit vs. illicit opioid use, and why heroin users were 2.5 times more likely to use kratom than users of other substances. We talk about the motivations for why low income people may either prefer or are required by circumstance to turn to diverted buprenorphine (meaning obtained legally but sold illegally) or kratom instead of prescription drugs or Medication Assisted Treatment. The paper examines the scarcity of MAT resources in Kentucky. Dr. Jon also talks about the limitations of the study and his problem with one aspects of the study's conclusion.

A new study from Thailand (La-up, 2021) found traditional users of kratom had elevated levels of high-density lipoprotein (HDL or “good” cholesterol) and low levels of triglycerides. In the largest recent study of its kind, researchers recruited 581 participants, half kratom consumers, and half who did not consume kratom as a control group. Though the consumers of traditional kratom (fresh leaves brewed or chewed) had higher instances of drinking and smoking, they showed healthier cholesterol levels than the control group. Many fruits and vegetables rich in antioxidants also promote healthy cholesterol, and you'd expect that from a dark green leafy food like kratom.

Neuroscientist Dr. Jonathan Cachat and host Brian Gallagher look at the blistering report by Jane Babin released in August 2018: "FDA Fails to Follow the Science on Kratom" (PDF available here https://t.co/G76TVsWdLY?amp=1 ). Babin demonstrates how FDA manipulated data to create a Schedule I justification based on what a former HHS Assistant Secretary of Health Brett Giroir called "embarrassingly poor evidence & data, and a failure to consider overall public health." FDA systematically omitted data, left out instances of polydrug consumption, failed to cite original case reports, and labelled suicides, homicides, and accidents as "kratom related deaths". Since 2012, FDA has REPEATEDLY cited this bad information as justification of import alerts, seizures, and their push to make kratom a Schedule 1 drug. We look at Dr. Babin's report in detail.

In a departure from kratom science, Dr. Cachat and Brian look at a paper by a pioneering pharmacologist and researcher in the field of psychedelics, Dr. David E. Nichols. Dr. Nichols methodically lays out his case for why endogenous DMT produced in the pineal gland, brain, or other parts of the human body is not present at adequate enough doses to be psychoactive. Therefore there is not enough evidence that endogenous DMT explains out-of-body experiences or near-death experience. This is controversial in drug nerd world as evidence by YouTube comments on a related talk given by Dr. Nichols, and may run counter to Rick Strassman's arguments presented in his popular book and documentary The Spirit Molecule. Is endogenous DMT a neurotransmitter? If not what is it? If DMT doesn't explain near death experiences, what does?

Another study from University of Florida is the “first report that has simultaneously evaluated the systemic exposure of 11 kratom alkaloids following the administration of traditional and commercial kratom products” (Kamble, 2021). Researchers looked at the pharmacokinectics (how drugs move through the body and are metabolized) of alkaloids in rat plasma following the oral administration of both kratom tea and a commercial liquid extract.
This study lays the groundwork for future research into the difference between “natural” kratom and extracts, and how the alkaloids act in concert, or as Dr. Cachat calls, the “entourage effect”, versus how they act separately.

Dr. Cachat continues answering questions from February's r/kratom Ask Me Anything. This time we talk about whether kratom will follow the path of cannabis in terms of regulation, if kratom will be turned into a pharmaceutical drug, kratom and dopamine agonists, kratom and libido, and random weird effects that probably aren't caused by kratom.

We all know the mitragynine and 7-hydroxymitraginine act on the mu-opioid receptor. But for episode #13 of Journal Club we talk about a study that looks closely at the binding affinity of various kratom alkaloids on the plethora of opioid and adrenergic receptors in the brain. How exactly does this work? How do different alkaloids lead to the multiple functional effects of kratom? Are we fish out of water when it comes to molecular chemistry? Guesses and possibly even answers, plus listener mail, in episode #13 of Kratom Science Journal Club.

This time Dr. Jonathan Cachat and I look at a study where a team from University of Florida cultivated 68 kratom trees in a greenhouse, gave them varying levels of fertilizer, and measured for biomass, chlorophyll, and alkaloid content. Dr. Jon talks about similar studies he did with cannabis, and we go into what that would mean for a domestic kratom agriculture industry, home growers, and further science on the plant biology of kratom.

Happy Thanksgiving! The holidays after a rough year are always a great time to drink like a fish. In this episode we explore kratom and alcohol. Emerging testimony and research indicates kratom may be an effective harm reduction tool to cut down on alcohol consumption, withdrawal, and cravings. We read testimony from KratomScience.com commenters, then get into a study showing four isolated kratom alkaloids all decreased alcohol consumption in mice.

A study on kratom’s chemical composition asks, what does the little-researched kratom alkaloid speciofoline do? And what are the implications for drug interactions and the differences in alkaloid content in kratom products?
The brand new study published last week in Scientific Reports examined the chemical composition of 53 kratom products and divided them into two categories: high-speciofoline and low-speciofoline. As in previous studies, the researchers found kratom may be a safer treatment alternative than classical opioids because of how it acts on the mu-opioid receptor, but can kratom create risks for drug interactions if it slows liver metabolism of other drugs? The study of the alkaloid speciofoline may bring us closer to understanding why different kratom products have slightly differing effects. Does the color code of kratom product varieties -- red (for bed), white (for flight), and green (in between) -- hold water?

This week we look at a study by a team from University of Florida called “Lyophilized Kratom Tea as a Therapeutic Option for Opioid Dependence”. The science is catching up with what thousands of kratom consumers are saying -- that kratom can be a safe and effective harm reduction tool for opioid withdrawal and dependence. In 2018 and 2019, University of Florida College of Pharmacy received close to $7 million in grants from the National Institutes on Drug Abuse to study kratom.

Host Brian Gallagher and Dr. Jonathan Cachat welcome Dr. Marc Swogger, social scientist and clinical psychologist at the University of Rochester Medical Center to discuss his 2018 article published in Drug and Alcohol Dependence "Kratom Use and Mental Health: A Systematic Review". Along with co-author Zach Walsh, Dr. Swogger looked at all the literature published up to 2017 about mental health issues surrounding kratom consumption. We talk about why mostly men use kratom, cultural differences between Eastern and Western kratom consumption, the consistency of outcomes among careful kratom science vs. sloppy studies with foregone negative conclusions. Plus, Dr. Marc answers another Mark E. Smith question.

We discuss this study from 1972 that tested the effects of mitragynine in rats, mice, cats, dogs, and monkeys. Dr. Jon talks about the difference between now and then in pharmacology labs. Similar conclusions about the effects of mitragynine and its relative safety in relation to opiates, but why was mitragynine never developed as a pain management drug, especially by the company that conducted this study, that would later merge into pharmaceutical giant Glaxo SmithKline? We examine how a mitragynine dose as high as 920 mg/kg in a mouse produced no evidence of toxicity. And a bit about mitragynine and metabolism.

Dr. Cachat and I talk about a study that tested rats with morphine, mitragynine, naloxone, buprenorphine, and rimonabant, and measured responses based on food-reinforcement training. The study concluded "The findings suggest that MG does not induce physiological dependence but can alleviate the physical symptoms associated with morphine withdrawal". We talk about how the rats are trained, what can be concluded from experiments based on responses alone, mitragynine extraction methods, extracted mitragynine vs. kratom methods of administration and effects, how cannabinoid and opioid receptors interact, and why studying kratom alkaloids might lead to the "holy grail" of pain management.

This is the Kratom Science Journal Club with Dr. Jonathan Cachat, neuroscientist and expert in psychopharmacology. In each episode we discuss an article in a peer reviewed journal.
For episode 2 we discuss the article, “The Potential for Kratom as an Antidepressant and Antipsychotic” published in Yale Journal of Biology and Medicine, edition 93, June 2020 and co-authored by Kratom Science Podcast guest Marc Swogger.
How do dopamine, serotonin, and cortisol work to affect psychosis and depression? What effect does mitragynine have on our brains? How is mitragynine metabolized? How does kratom work differently from opiates and psychedelics? And finally why were these substances made illegal, rendering these questions tough to answer even in the 21st century?
