Correlations of kratom (Mitragyna speciosa Korth.) use behavior and psychiatric conditions from a cross-sectional survey.

Kratom (Mitragyna speciosa Korth.) use has increased substantially over the past decade outside of its indigenous regions, especially for the self-treatment of psychiatric conditions. An anonymous, cross-sectional, online survey was completed by 4,945 people who use kratom (PWUK) between July 2019 and July 2020. A total of 2,296 respondents completed an extended survey that included clinical scales for measuring attention deficit hyperactivity disorder (ADHD), posttraumatic stress disorder (PTSD), depressive and anxiety disorders. PWUK and met criteria for ADHD, PTSD, depressive or anxiety disorders were primarily middle-aged (31-50 years), employed, college-level educated, and reported greater concurrent or prior use of kratom with cannabis, cannabidiol, and benzodiazepines. For all psychiatric conditions, PWUK reported decreased depressive and anxious moods than before kratom use. Based on this self-report study, observational and other clinical studies are warranted for kratom. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Depressive Symptoms Moderate the Association Between the Recent History of Alcohol Use Severity and Suicide Attempt History Among Adults in a Pretrial Jail Diversion Program.

Background: Justice-involved individuals are at elevated risk for suicidal behavior; however, research examining risk for suicidal behavior in pretrial jail diversion programs (pretrial diversion) is limited. Aims: We aimed to test (1) associations between depressive symptoms and alcohol and drug use, and suicide attempt history (SAH), and (2) interactions between depressive symptoms and alcohol and drug use in relation to SAH among adults in an urban pretrial jail diversion program. Method: The design was cross-sectional, including self-report assessments and file reviews of historical information. Adults (N = 274; Mage = 33.72; 73.7% men; 52.6% non-Hispanic Black) completed assessments within two weeks of beginning the pretrial program. Results: Depressive symptoms were positively associated with SAH after adjusting for other covariates. The significant depressive symptoms by alcohol use interaction indicated that adults with low to average depressive symptoms evidenced a similar likelihood of SAH to those with high depressive symptoms when they also had elevated alcohol use scores. Limitations: We used cross-sectional self-report data. Conclusion: It may be important to conduct suicide risk assessments for justice-involved people who use alcohol even when depressive symptoms are low.

Kratom use as more than a "self-treatment".

Background: Mitragyna speciosa (kratom) is increasingly used in the United States for its pharmacological effects. Kratom's relative novelty makes for a dynamic situation, such that use motivations are not firmly established and may be changing. Investigators and clinicians require frequent updates on kratom trends.Objectives: To assess the current state of kratom-use initiation, sourcing, motivations, preference, conceptualizations, and perceived stigma, using survey responses from current and former users.Methods: Between April-May 2021 we recontacted 289 respondents who reported lifetime kratom use (on an unrelated survey) to answer kratom-specific questions.Results: The sample (N=129) was majority female (51.9%) and white (71.9%). Most (69.0%) reported first trying kratom after 2015. Mean age of use initiation (29.9 years) was older than for other substances, including opioids. Kratom ranked as a preferred substance by 48.5%. The strongest drug association with past-year kratom use was vaped nicotine (OR=3.31,95% CI 1.23-8.88). Use was less likely among those prescribed buprenorphine in the past year (OR=0.03, CI 0.01-0.28). Past-month cannabis use (OR=4.18,CI 1.80-9.72) had the strongest association with past-month kratom use. Over 40 use motivations were endorsed, many (but not all) supporting the "self-treatment" narrative of kratom use, including use as an opioid, alcohol, or stimulant substitute. Treatment shortfalls were associated with decisions to try kratom.Conclusions: Kratom use motivations are diversifying, with multiple factors driving use. As sales continue to increase, the public-health, clinical, and policy responses to kratom should be grounded in rigorous bench-to-bedside scientific research. Comprehensive study of kratom is currently lacking.

Exploring the self-reported motivations of kratom (Mitragyna speciosa Korth.) use: a cross-sectional investigation.

Background: Kratom (Mitragyna speciosa Korth.) use outside of Southeast Asia has increased over the past decade. Objectives: This investigation clarifies kratom's role in perceived well-being, overall health, and temporal correlation with drug use to understand kratom's role in the self-treatment of substance use disorders (SUDs). Methods: Between July 2019 and July 2020 an anonymous, cross-sectional, online survey was taken by 7,381 people who use kratom (PWUK) recruited through social media and other online resources. This included an assessment of (a) the relationship between self-reported overall health, concomitant use of drugs of misuse, and demographics; (b) the perceived effectiveness of kratom in self-treating diagnosed health conditions or symptoms; (c) the profile of PWUK primarily for drug dependence, pain, and mood or mental health conditions based on demographics. Results: A total of 5,152 valid responses (45.9% females/53.7% males) were collected. Kratom was primarily used for self-treating pain (73.0%) and improving emotional or mental health conditions (42.2%) without clinical supervision. Those with a SUD (synthetic opioids, methadone, benzodiazepines, or heroin) used kratom after discontinuing illicit or other drugs (94.8%). The primary substances taken before or concomitantly with kratom were cannabis, cannabidiol, benzodiazepines, or kava. PWUKs report a dose-dependent benefit for alleviating pain and relieving negative moods. Adverse effects were primarily gastrointestinal, typically at high (>5 g/dose) and frequent (>22 doses/week) dosing. Conclusions: Kratom was primarily used as a harm-reduction agent for SUDs and self-treatment of chronic conditions. Healthcare professionals need better information about kratom, its potential adverse effects, and clinically significant drug interactions.

Understanding Kratom Use: A Guide for Healthcare Providers.

Kratom (Mitragyna speciosa Korth., Rubiaceae) is a plant native to Southeast Asia, where it has been used for centuries as a mild stimulant and as medicine for various ailments. More recently, as kratom has gained popularity in the West, United States federal agencies have raised concerns over its safety leading to criminalization in some states and cities. Some of these safety concerns have echoed across media and broad-based health websites and, in the absence of clinical trials to test kratom's efficacy and safety, considerable confusion has arisen among healthcare providers. There is, however, a growing literature of peer-reviewed science that can inform healthcare providers so that they are better equipped to discuss kratom use with consumers and people considering kratom use within the context of their overall health and safety, while recognizing that neither kratom nor any of its constituent substances or metabolites have been approved as safe and effective for any disease. An especially important gap in safety-related science is the use of kratom in combination with physiologically active substances and medicines. With these caveats in mind we provide a comprehensive overview of the available science on kratom that has the potential to i clarity for healthcare providers and patients. We conclude by making recommendations for best practices in working with people who use kratom.

Social, psychological, and substance use characteristics of U.S. adults who use kratom: Initial findings from an online, crowdsourced study.

Kratom, a plant that produces opioid-like effects, has gained popularity in the U.S. for self-treating symptoms of chronic pain, mood disorders, and substance-use disorders (SUDs). Most data on kratom are from surveys into which current kratom-using adults could self-select; such surveys may underrepresent people who have used kratom and chosen to stop. Available data also do not adequately assess important psychosocial factors surrounding kratom use. In this study, U.S. adults who reported past 6-month alcohol, opioid, and/or stimulant use (N = 1,670) were recruited via Amazon Mechanical Turk between September and December 2020. Of the 1,510 evaluable respondents, 202 (13.4%) reported lifetime kratom use. Kratom-using adults, relative to others, were typically younger, male, unpartnered, without children, and had lower income. They had higher rates of chronic pain (31.7% vs. 21.9%, p = .003), childhood adversity, anxiety, and depression (p < .001), and lower perceived social rank (d = .19, .02-.22) and socioeconomic status (d = .37 .16-.26). They also reported higher use rates for most substances (except alcohol); this included medically supervised and unsupervised use of prescription opioids and diverted opioid agonist therapy (OAT) medications. Most (83.2%) met diagnostic criteria for any past-year SUD. Those reporting kratom use were less likely to reside in an urban/suburban area. The strongest predictors of kratom use were use of other drugs: cannabidiol (OR = 3.73), psychedelics (OR = 3.39), and nonmedical prescription opioids (OR = 1.72). Another strong predictor was lifetime OAT utilization (OR = 2.31). Despite seemingly poorer psychosocial functioning and health among respondents reporting lifetime kratom use, use of other substances may be the strongest indicators of kratom use.

BRIEF MOTIVATIONAL INTERVENTION FOR SUBSTANCE USE MAY DECREASE VIOLENCE AMONG HEAVY ALCOHOL USERS IN A JAIL DIVERSION PROGRAM.

Rates of harmful alcohol use are high among justice-involved individuals and may contribute to violent recidivism. Robust treatments for alcohol-related violence in criminal justice systems are thus a public health priority. In this analysis of existing randomized controlled trial data (N = 105), we examined the impact of a brief motivational intervention (BMI) for harmful substance use on violent recidivism among individuals in a pretrial jail diversion program. Results indicated that, after controlling for violence history, the intervention's impact on violent recidivism was moderated by baseline harmful alcohol use. Specifically, among people with severe alcohol problems at baseline, the BMI + standard care group had less violent recidivism at a 1-year follow-up than participants randomized to standard care alone. This finding was unchanged when we accounted for psychopathic traits. Our study provides preliminary evidence that a BMI may be useful for decreasing violent recidivism among heavy drinkers in criminal justice systems.

Substance use, current criminal justice involvement, and lifetime suicidal thoughts and behaviors history: The moderating role of thwarted belonging.

OBJECTIVE: Criminal justice involvement, substance use, and suicide pose significant public health concerns; however, the unique and synergistic effects of these experiences among high-risk individuals remain understudied. We hypothesized positive main effects for alcohol-related severity, drug-related severity, current criminal justice involvement, and thwarted belonging (TB) on suicide ideation history (SIH) and suicide attempt history (SAH) and that TB would moderate these associations. METHOD: We report on cross-sectional analyses of self-report assessments completed by 824 adult residential substance use patients. RESULTS: Multinomial logistic regression analyses indicated that as alcohol- and drug-related severity increases, the probability of SIH and SAH increases; however, TB was only associated with a higher SIH probability. Significant two-way interactions (current criminal justice involvement*TB; alcohol-related severity*TB) indicated that (1) those high in TB with current criminal justice involvement were more likely to report a SIH than those without current criminal justice involvement; and (2) those low in TB and alcohol-related severity had the lowest SAH probability, whereas those low in TB and high in alcohol-related severity had the highest SAH probability. CONCLUSION: The unique and combined effects of interpersonal and contextual risk factors may improve suicide risk conceptualization and assessment, and allow for tailored treatments for this high-risk population.

Current and Future Potential Impact of COVID-19 on Kratom (Mitragyna speciosa Korth.) Supply and Use.

Kratom (Mitragyna speciosa Korth., Rubiaceae) is native to and has traditional use in Southeast Asia. The number of kratom users outside of Southeast Asia has increased significantly in recent decades with use spreading to the Unites States (US) and Europe. Because of its reputed opioid-like psychoactive effects at higher doses, kratom has been regulated in several countries and is subject to an import ban by the US Food and Drug Administration. Nonetheless, in the US it is estimated that 10-15 million people consume kratom primarily for the self-treatment of pain, psychiatric disorders, to mitigate withdrawal from or dependence on opioids, and to self-treat opioid use disorder or other substance use disorders (SUDs). Due to the global COVID-19 pandemic, a shortage in the supply of kratom products may place unexpected burdens on kratom users, potentially influencing some who use kratom for SUD self-treatment to regress to harmful drug use, hence increasing the likelihood of adverse outcomes, including overdose. Inadequate treatment, treatment barriers, and increases in the sales of adulterated kratom products on the internet or in convenience stores could exacerbate circumstances further. Although there are currently no verified indications of kratom scarcity, researchers and clinicians should be aware of and remain vigilant to this unanticipated possibility.

Lifetime History of Suicide Attempts among Not Guilty by Reason of Insanity State Hospital Inpatients: The Roles of past Harmful Substance Use and Current Social Support.

This study tested current perceived social support (CPSS) as a moderator of the relation between previous substance use (PSU) and lifetime suicide attempt (SA) history among 200 NGRI inpatients. Results indicated no significant CPSS main effect. PSU was associated with greater odds of multiple prior lifetime SA. Moderation indicated those low in PSU but high in CPSS were least likely to report multiple prior lifetime SA. Conversely, NGRI inpatients with high CPSS and high PSU were most likely to report multiple lifetime SA. Our study suggests CPSS and PSU assessments may inform suicide risk assessments and interventions among NGRI inpatients.

The Potential for Kratom as an Antidepressant and Antipsychotic.

Mitragyna speciosa, otherwise known as kratom, is a plant in the coffee family (Rubiaceae) native to Southeast Asia and Thailand whose leaves have been shown to cause opioid-like and stimulant responses upon ingestion. The major pharmacologically active compounds present in kratom, mitragynine and 7-hydroxymitragynine (7-HMG), are both indole alkaloids and are responsible for its opioid-like activity. While kratom is most commonly known for its affinity for mu-opioid receptors, research has shown one of its active components has effects on the same receptors to which some antipsychotics bind, such as D2 dopamine, serotonin (5-HT2C and 5-HT7), and alpha-2 adrenergic receptors displaying possible indications of kratom to be used as both antipsychotics and antidepressants. Although studies to evaluate this effect are still lacking, several online and in-person surveys note relief of depression and anxiety symptoms among those who consume kratom products, and in fact identify it as a common reason for consumption. This then highlights the dire need for further research to be conducted on kratom, its mechanism of action and the constituents that elicit these antidepressant, anxiolytic, and antipsychotic properties.

Public Perceptions toward Kratom (Mitragyna Speciosa) Use in Malaysia.

Kratom (Mitragyna speciosa), an indigenous medicinal plant of Southeast Asia, is believed to be harmful. We compared the perceptions toward kratom use among kratom users and non-users in Malaysia. 356 respondents (137 kratom users and 219 non-users) were recruited for this cross-sectional study. The majority of respondents were male (60%, n = 212/356), Malays (88%), and 51% were ≥37 years old. Non-users showed higher unadjusted odds of reporting a perception that kratom use can cause addiction (OR = 6.72, CI: 3.91-11.54, p < .0001), withdrawal symptoms (OR = 7.58, CI: 4.62-12.42, p < .0001), illicit drug use problems (OR = 10.12, CI: 6.14-16.68, p < .0001), impaired social-functioning (OR = 12.05, CI: 7.24-20.05, p < .0001), and health problems (OR = 10.44, CI: 6.32-17.24, p < .0001). Similarly, non-users viewed kratom policies differently from kratom users, displaying increased odds of reporting the belief that kratom use and sales must be regulated with stringent laws (OR = 5.75, CI: 3.61-9.18, p < .0001), and kratom should be regulated instead under the Dangerous Drugs Act 1952 to overcome kratom use problems (OR = 8.26, CI: 4.94-13.82, p < .0001). Because of the disconnect in kratom use perceptions and personal experiences between kratom users and non-users, hastily criminalizing kratom without investigating carefully its scientific merits can significantly impede future kratom research.

Self-Report Data on Regular Consumption of Illicit Drugs and HIV Risk Behaviors after Kratom (Mitragyna Speciosa korth.) Initiation among Illicit Drug Users in Malaysia.

This study sought to determine the relationship between kratom (Mitragyna speciosa) initiation and regular consumption of illicit drugs and HIV risk behaviors in a cohort of illicit drug users in Malaysia. 260 illicit drug users with current kratom use were recruited through convenience sampling for this cross-sectional study. All were male, with the majority being Malays (95%, n = 246/260). Results suggest that kratom initiation was associated with significant decrease in the regular use of heroin (odds ratio (OR) = 0.50, 95% confidence interval (CI): 0.40- 0.72; p = .0001), methamphetamine (OR = 0.23, CI: 0.16- 0.35; p < .0001), and amphetamine (OR = 0.17, CI: 0.09- 0.34; p < .0001). Kratom initiation was also associated with reduction in regular HIV risk behaviors such as having sex with sex workers (OR = 0.20, CI: 0.12-0.32; p < .0001), using drugs before sexual intercourse (OR = 0.20, CI: 0.13- 0.31; p < .0001), injecting behaviors (OR = 0.10, CI: 0.04- 0.25; p < .0001), sharing of injection equipment (OR = 0.13, CI: 0.04- 0.43; p < .0001), and injecting with other injection drug users (IDUs) (OR = 0.07, CI: 0.02- 0.24; p < .0001).

The prevalence of psychotic symptoms in kratom (Mitragyna speciosa Korth.) Users in Malaysia.

BACKGROUND: Kratom is a traditional medicinal herb widely used in Malaysia and Thailand. Despite its widespread use and statements by regulatory agencies on the potential for kratom-associated psychosis, there is little data regarding the prevalence of psychotic symptoms among kratom users. This study investigated the prevalence of psychosis among kratom users, described psychotic symptomatology and severity, while examining associations between kratom use characteristics and the occurrence of psychotic symptoms. METHODS: This cross-sectional clinical survey recruited 150 regular kratom users. The Mini International Neuropsychiatric Interview (MINI) and Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-V) diagnostic criteria were used to evaluate psychotic symptomatology among kratom users, and the Brief Psychiatric Rating Scale (BPRS) was used to assess the severity of psychiatric symptoms. Chi-square tests with Yate's correction were performed to determine the association between kratom use characteristics and the occurrence of psychotic symptoms among kratom users in this study. RESULTS: Six out of 150 kratom users (4%) presented with any psychotic symptoms. The psychotic symptoms reported were positive symptoms and thought alienation, with a mean BPRS score of 33 (i.e., mild severity). Variables related to kratom use (such as intake of kratom with diphenhydramine, duration of kratom use, and quantity and frequency of daily kratom use) were not associated with the occurrence of psychotic symptoms among kratom users. CONCLUSION: Although psychotic symptoms could occur among regular kratom users, they were rare and not significantly associated with kratom use characteristics. We found no evidence of elevated psychosis among regular users.

Kratom policy: The challenge of balancing therapeutic potential with public safety.

Kratom (Mitragyna speciosa) is a tree-like plant indigenous to Southeast Asia. Its leaves, and the teas brewed from them have long been used by people in that region to stave off fatigue and to manage pain and opioid withdrawal. Evidence suggests kratom is being increasingly used by people in the United States and Europe for the self-management of opioid withdrawal and treatment of pain. Recent studies have confirmed that kratom and its chemical constituents have potentially useful pharmacological actions. However, there have also been increasing numbers of reports of adverse effects resulting from use of kratom products. In August 2016, the US Drug Enforcement Administration announced plans to classify kratom and its mitragynine constituents as Schedule I Controlled Substances, a move that triggered a massive response from pro-kratom advocates. The debate regarding the risks, and benefits and safety of kratom continues to intensify. Kratom proponents tout kratom as a safer and less addictive alternative to opioids for the management of pain and opioid addiction. The anti-kratom faction argues that kratom, itself, is a dangerous and addictive drug that ought to be banned. Given the widespread use of kratom and the extensive media attention it is receiving, it is important for physicians, scientists and policy makers to be knowledgeable about the subject. The purpose of this commentary is to update readers about recent developments and controversies in this rapidly evolving area. All of the authors are engaged in various aspects of kratom research and it is our intention to provide a fair and balanced overview that can form the basis for informed decisions on kratom policy. Our conclusions from these analyses are: (a) User reports and results of preclinical studies in animals strongly suggest that kratom and its main constituent alkaloid, mitragynine may have useful activity in alleviating pain and managing symptoms of opioid withdrawal, even though well-controlled clinical trials have yet to be done. (b) Even though kratom lacks many of the toxicities of classic opioids, there are legitimate concerns about the safety and lack of quality control of purported "kratom" products that are being sold in the US. (c) The issues regarding the safety and efficacy of kratom and its mitragynine constituent can only be resolved by additional research. Classification of the Mitragyna alkaloids as Schedule I controlled substances would substantially impede this important research on kratom.
