Abstract
INTRODUCTION Kratom (Mitragyna speciosa) is a medicinal tree native to Southeast Asia. The present multilevel meta-analysis describes the association between kratom use and the positive and negative indicators of mental health. METHODS A total of thirty-six articles were included in the meta-analysis to examine the associations, using a random-effects model. RESULTS The pooled effect size showed a very small positive association between kratom use and negative indicators of mental health {r = 0.092, 95% confidence interval (CI) = [0.020, 0.164], p < 0.05}, while no significant association was found with positive indicators of mental health (r = -0.031, 95% CI = [-0.149, 0.087], p > 0.05). Pooled effect sizes of specific mental health outcomes indicated that kratom use showed only a small positive correlation with externalizing disorders (r = 0.201, 95% CI = [0.107, 0.300], p < 0.001). No significant association was found between kratom use and quality of life (r = 0.069, 95% CI = [-0.104, 0.242], p > 0.05) and internalizing disorders (r = -0.001, 95% CI = [-0.115, 0.095], p > 0.05). Multilevel moderator analysis showed that the pooled effect size of the association between kratom use and substance use disorder was stronger in Malaysia (r = 0.347, 95% CI = [0.209, 0.516], p < 0.001), and with the mean age (β1 = -0.035, 95% CI = [-0.055, -0.014], p = 0.003), and the drug profile of those who were not co-using other drugs (r = 0.347, 95% CI = [0.209, 0.516], p < 0.001). CONCLUSION The meta-analysis supports the kratom instrumentalization concept, in that a positive gain from kratom consumption can be achieved without any significant adverse associations with mental health.

Abstract
OBJECTIVE Despite kratom impacting neurobiological systems involved in psychiatric disorders, little is known about the prevalence of use among patients with severe psychopathologies. Here, we investigated the prevalence of kratom use, motives for use, and the clinical associations among inpatients with severe psychiatric disorders. METHODS A total of 578 patients, aged 18 to 65, were evaluated by New Hampshire Hospital's Addiction Services from January 1, 2020, to February 28, 2022. The study collected demographic information and used chi-square tests, multivariable logistic regression, and subgroup analyses with 95% confidence intervals to examine trends among kratom users. A receiver operating characteristic curve analysis was also conducted. All statistical tests were performed using IBM SPSS Version 28.0.1. RESULTS Of the patients assessed, 2.2% (n = 13) reported using kratom. The reasons for kratom use were managing withdrawal symptoms (15.4%), maintaining sobriety and reducing cravings for opioids (53.8%), improving focus and concentration (30.8%), alleviating low moods (38.5%), and managing pain (15.4%). Compared to non-kratom users, the only factor with a fair to good association with kratom use is postsecondary education (Area Under Curve, AUC = 0.77). CONCLUSIONS Prevalence of kratom use among patients with serious mental illness at our site aligns with that reported in the general population. Users often cite self-management of cravings and sobriety from opioids, as well as treatment of low mood states, as motivations for consumption. While observations suggest a possible association between kratom use and individuals with post-secondary education, multiple substance use, and experience of substance-induced psychosis or mood disorders, it is essential to interpret these links cautiously until further rigorous studies are carried out to substantiate these findings.

Abstract
Purpose of Review Use of "kratom" products, derived from the bioactive botanical Mitragyna speciosa have increased amidst US polydrug use epidemics. Kratom alkaloids interact with opioid, serotonergic, adrenergic, and other receptors and regular users have described experiencing a wide range of effects. Some with polydrug use histories have reported using kratom as a substitute for other drugs or to nonmedically self-manage substance use disorder (SUD) symptoms. Data describing this remain scare and come from self-report. We review this literature describing kratom use as a drug substitute, or as a nonmedical "self-treatment" for attenuating dependence or SUD symptoms. Recent Findings Kratom products have been documented as being used as a licit and illicit opioid substitute. Use to reduce alcohol or stimulant consumption is less well documented. Although prior and current polydrug use appear common among a some kratom users, it is unclear if co-use is contemporaneous or concomitant. Temporal order of use initiation is typically undocumented. Use for energy and recreation are also increasingly reported. Summary Data on kratom consumption come primarily from self-report with significant limitations. Until controlled human laboratory studies have been conducted, we can presently only describe what is known about human kratom use based on self-report. Such data describe real-world kratom use, leaving unaddressed human abuse liability or therapeutic potential of kratom alkaloids. Clinicians should be mindful of use motivations among people with SUD histories, sensitively assessing use. The paucity of data highlights the urgent need to increase funding and research for understanding kratom's effects in humans.

Subst Abuse Treat Prev Policy 2023; 18:21. [PMID: 37041624 PMCID: PMC10088264 DOI: 10.1186/s13011-023-00531-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 03/27/2023] [Indexed: 04/13/2023] Open
Abstract
BACKGROUND "Kratom" commonly refers to the botanical Mitragyna speciosa, native to Southeast Asia, which is increasingly used globally for its unique pharmacological effects. Motives for using the whole plant material or kratom-derived products include self-management of pain, mental health disorders, symptoms related to substance use disorders, and/or to increase energy. In the United States, kratom products have varying alkaloid content, potencies, and marketing profiles. There is little regulatory oversight over kratom, as it is currently not approved as a dietary supplement by the Food and Drug Administration. This results in substantial variability in labeling of kratom products and the product information provided to consumers. METHODS In January 2023, we evaluated the American Kratom Association's Good Manufacturing Practices (GMP) qualified vendors' websites (n = 42) using the well-established and validated DISCERN instrument to examine the quality of health information provided to consumers. DISCERN contains 15 five-point Likert-scale questions on specific criteria, with the highest possible score being 75, indicating that all the DISCERN criteria have been fulfilled by the website (i.e., the highest quality information is provided to consumers). RESULTS The mean DISCERN score for all evaluated online kratom vendors was 32.72 (SD = 6.69; score range 18.00-43.76). Overall, vendors scored higher on DISCERN questions assessing the website's reliability, as vendors typically provided clear information for consumers about product availability, purchasing, shipping, etc. On average, vendors scored poorly on the DISCERN section pertaining to the quality of the health information provided. Information on kratom's potential risks and benefits was particularly insufficient. CONCLUSIONS Consumers require high quality information in order to make informed decisions concerning use, which entails disclosure of known risks and potential benefits. The online kratom vendors evaluated in this study should consider enhancing the quality of health information provided, especially information regarding kratom's risks and benefits. Further, consumers should be made aware of current knowledge gaps related to kratom's effects. Clinicians must also be aware of the lack of evidence-based information available to their patients who use kratom or are interested in using kratom products, in order to facilitate educational discussions with them.

J Psychoactive Drugs 2023; 55:102-111.

Abstract
To shed more light on the addictive power of the gabapentinoids (GPTs) gabapentin and pregabalin, we performed a structured face-to-face interview with GPT-users about DSM-IV-dependence-criteria (sedatives), consume-motives and cessation-needs. Among 100 patients consecutively admitted to a detoxification-ward, fifteen (15%) reported lifetime GPT-use (18-50 years old, 2 females): seven (7%) used gabapentin, twelve (12%) pregabalin and four had lifetime experiences with both GPTs. Of the seven gabapentin-users, three patients were dependent including one person with a spontaneous remission. Of the 12 pregabalin-users, five were dependent, including two persons with a spontaneous remission. Fourteen of fifteen cases reported GPT-use side-by-side with an opioid-use, mostly for sparing opioids. Twelve GPT-users additionally co-used benzodiazepines. In no case, a GPT was the reason for detoxification treatment or reported to be involved in an emergency event. Altogether, every 7th patient (n = 15) of our inpatient detoxification-seeking sample reported GPT-use including 50% (n = 8) who were dependent. Among them, 35% (3/8) had been already spontaneously remitted. As GPT-users reported no cession-need and the vast majority were primarily affected by co-occurring opioid- and benzodiazepine-addiction, we assume that GPTs more likely played a bystander-role than mediating the addictive behavior of this population with multiple recreational drug use experience.

Abstract
BACKGROUND AND OBJECTIVES Kratom (Mitragyna speciosa) use is associated with polysubstance use (PSU) and use disorders. However, additional research on PSU heterogeneity in populations using this novel psychoactive substance is necessary. The authors investigated patterns of past 12-month PSU among US adults reporting past 12-month use of kratom and at least one additional substance. METHODS Latent class models were fit using 2019 National Survey on Drug Use and Health (NSDUH) data which was collected from 412 US adults reporting past 12-month use of kratom and at least one of 11 additional substances. RESULTS Three distinct profiles were identified: "marijuana/alcohol/tobacco" (63.3%), "marijuana/alcohol/tobacco + psychedelics" (19.3%), and "marijuana/alcohol/tobacco + psychedelics/heroin/prescriptions" (17.4%). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE This is the first epidemiological study in which a latent class analysis was used to identify unique PSU profiles among US adults using kratom and other substances. Understanding the profiles of people using kratom in relation to the use of other drugs might help guide screening interventions, treatment needs, and policy.

Abstract
BACKGROUND Kratom, a psychoactive substance, use is an evolving research area that needs more studies to augment the limited literature. Our study examines the association between kratom use categories and mental health and substance use disorders in the U.S. METHODS We used the 2020 National Survey on Drug Use and Health data (N = 32,893), a cross-sectional survey data, on the U.S. population aged 12 years or older. We used STATA/SE version 16 to perform a multinomial logistic regression analysis to assess our study aims. RESULTS Bisexuals, compared to heterosexuals, had higher risks of kratom use within the past 30 days (relative risk ratio [RRR]= 2.47, 95% CI= 1.07, 5.71). Major depressive episode was positively associated with kratom use more than 30 days ago (RRR= 2.04, 95% CI= 1.24, 3.34). This association was also observed for mild (RRR= 2.04, 95% CI= 1.38, 3.02), moderate (RRR= 2.25, 95% CI= 1.13, 4.51), or severe alcohol use disorder (RRR= 1.88, 95% CI= 1.05, 3.36); and mild (RRR= 1.98, 95% CI= 1.27, 3.11), moderate (RRR= 2.38, 95% CI= 1.27, 4.45), or severe marijuana use disorder (RRR= 2.13, 95% CI= 1.02, 4.47). Illicit drug other than marijuana use disorder was associated positively with kratom use more than 30 days ago (RRR= 2.81, 95% CI= 1.85, 4.26) and kratom use within the past 30 days (RRR= 5.48, 95% CI= 1.50, 20.02). CONCLUSIONS Our findings suggested that identifying as bisexual, experiencing depression, alcohol use disorder, or illicit drug use disorder increased the risks of kratom use. There is a need to consider mental health and substance use disorders and sexual identity in kratom use interventions and policies geared toward reducing or preventing kratom use.

Health Effects Associated With Kratom ( Mitragyna speciosa) and Polysubstance Use: A Narrative Review. Subst Abuse 2022; 16:11782218221095873. [PMID: 35645563 PMCID: PMC9130800 DOI: 10.1177/11782218221095873] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Accepted: 04/01/2022] [Indexed: 11/15/2022]
Abstract
Background Kratom (Mitragyna speciosa) consumption and associated health effects have raised debates in the United States. Although most people using this herb do not experience adverse health effects associated with kratom use, medical providers should be knowledgeable of emerging substances and concurrent, sequential, or simultaneous use of other drugs which may impact healthcare recommendations and prescribing practices. Methods The objective of this narrative review was to elucidate selected health effects associated with using kratom-either alone or with other substances. Since scientifically controlled human subjects research on kratom use is still limited, relevant case reports were also described. Results Cardiovascular, gastrointestinal, neurological, and psychiatric effects associated with kratom use were especially notable, and in-utero exposure accompanied concern regarding a neonate's risk for developing neonatal abstinence syndrome. Our ability to identify and understand the role of this herb in kratom-associated fatalities is complicated since kratom is not routinely screened for in standard forensic toxicology. If a screening is performed, it is usually for the major alkaloid, mitragynine, as a surrogate for kratom use. In addition to lacking a standard practice of screening decedents for kratom alkaloids, the association between mortality and kratom use may be confounded by polysubstance use, adulteration of kratom products, and drug-herb interactions. Conclusions Increasing medical awareness of this herb is vital to ensuring prompt administration of best-practice medical advice or treatment for people seeking information related to kratom use or for patients experiencing an adverse health effect that may be associated with using or withdrawing from kratom. Knowledge gained from continued surveillance and study of kratom and its associated health effects may assist in guiding clinical decision-making and preventing development of adverse health effects among people using kratom.
