Mitragyna speciosa or Kratom has been used in Thailand traditionally for its medicinal value. Despite case reports of kratom consumption causing adverse effects, research on its long-term health impact is limited. This study examines the long-term health impact of kratom use among people in Southern Thailand. Three community-based surveys were conducted from 2011 to 2015. In the first and second surveys (2011 and 2012) a total of 1,118 male respondents comprising 355 regular kratom users, 171 occasional kratom users, 66 ex-users, and 592 non-users aged 25 or above, were recruited from 40 villages. All respondents were followed up in this study. However, not all respondents were successfully followed up throughout the entire set of studies. Common health complaints were no more common among kratom users than ex- and non-users, but more regular than occasional users claimed kratom to be addictive. Those with high kratom dependence scores were more likely to experience intense withdrawal symptoms, which developed 1-12 h after the last kratom intake. Over half (57.9%) of regular users had experienced intoxication effects compared to only 29.3% of occasional users. Kratom users were less likely to have a history of chronic diseases such as diabetes, hypertension, dyslipidemia than ex- and non-users. Regular long-term chewing of fresh kratom leaves was not related to an increase in common health complaints, but may pose a drug dependence risk. Severe kratom dependents were more likely to suffer from intense withdrawal symptoms. Medical records revealed no death due to traditional kratom use, but the high prevalence of tobacco or/and hand rolled cigarette smoking among kratom users should be of concern.

Drinking, smoking, and health risk behaviors are significant problems for Thai adolescents. However, little is known about the association and magnitude among alcohol, tobacco, or co-using and health risk behaviors. Data of the National School Survey of 2007 were analyzed. The sample consisted of 50,033 high school and vocational college students. The interaction between gender and drinking-smoking status was significant for all health risk behaviors except for having sex and unprotected sex. Alcohol and tobacco had a stronger association with illegal substance use in boys than in girls. In contrast, their use had a stronger association with fighting, depression, and suicidal thoughts in girls than in boys. The intervention program for Thai youths in school should take into account the strong relationship between alcohol-tobacco consumption and these health risk behaviors. (Contains 3 tables.)

People who inject drugs (PWIDs) may engage in other behaviors with high risk of HIV transmission to various extents. However, data are scarce regarding differences in HIV testing and HIV positivity among PWIDs with and without high-risk behaviors. Such data can help inform stakeholders with regard to program prioritization. The objective of this study was to assess the extent that lifetime and past-year histories of HIV tests and HIV positivity varied by history of high-risk behaviors among PWIDs. We conducted a cross-sectional study with respondent-driven sampling (RDS) in the deep south provinces of Thailand during late 2019 thru early 2020. Data collection was done using structured questionnaire with face-to-face interviews. We analyzed data using descriptive statistics and multivariate logistic regression analyses. A total of 283 PWIDs gave verbal informed consent, and 282 PWIDs participated in the interview (n = 282 PWIDs). Approximately 44.6% of the participants never had an HIV test. Participants with history of high-risk behaviors had significantly higher odds of lifetime HIV testing than participants with no history of high-risk behaviors (Adjusted OR= 2.94; 95% CI [1.11, 7.78]). Among participants with lifetime history of HIV tests, those with history of high-risk behaviors had significantly higher odds of being HIV-positive than those with no history of high-risk behaviors (Adjusted OR = 2.44; 95% CI [0.73, 8.17]). Stakeholders should consider encouraging those without history of high-risk behaviors not to be complacent about HIV testing, and ensure that those with high-risk behaviors have full access to HIV care when they test positive.

Introduction Substance use during pregnancy contributes to the risk of adverse health outcomes in mothers and children-in utero and during later development. In this study, we investigated the prevalence of substance use and associated factors in pregnant women receiving antenatal care in public hospitals in Thailand. Methods Women (3578) attending 7 antenatal care clinics in Songkhla for the first time during their current pregnancy were interviewed with a structured questionnaire focusing on demographic data, obstetric history, use of alcohol, tobacco, and other substances, and the General Health Questionnaire was administered. The use of substances was confirmed with the ultrarapid version of the Alcohol, Smoking, and Substance Involvement Screening Test and urine tests, which were also administered to 1 in 5 to 10 randomly selected women whose screening results were negative. Results Based on self-reports and General Health Questionnaire results, the weighted prevalence of alcohol, tobacco, or illicit substance use and that of 'mental health problems' were 5.6% (95% confidence interval [CI], 4.9-6.4) and 29.2% (95% CI, 27.5-30.9), respectively. On the basis of the ultrarapid version of the Alcohol, Smoking, and Substance Involvement Screening Test and urine tests, the prevalence of likely substance use disorder during the 3 months prior to assessment was 1.2% (95% CI, 0.8-1.5) and 7.7% (95% CI, 4.6-10.7), respectively. Factors associated with substance use were religion, unmarried status, unplanned pregnancy, previous abortion, and current mental health problem. Discussion Our results emphasize the need for identification of substance use and mental health problems, with the help of questionnaires and biological markers, followed by early intervention.

Krathom (Mitragyna speciosa Korth.) is an addictive and illicit substance used in Thailand and other Southeast Asian countries. It has become the most commonly used substance among villagers. The study aimed to explore the factor structure of the krathom withdrawal syndrome based on the findings of an earlier qualitative study. The current study was divided into two stages. Cross-sectional data collections were employed in both phases. The samples comprised, respectively, 196 and 330 krathom users aged over 25 years. The characteristics of krathom withdrawal symptoms and signs were identified and the factor structure examined using exploratory factor analysis (EFA). Confirmatory Factor Analysis (CFA) was used to examine the construct validity and multivariate linear regression was used to identify factors predicting the intensity of krathom withdrawal symptoms. The final scale comprised 20 items with four factors: craving-fatigue syndrome; musculoskeletal system and insomnia; mood symptoms; and autonomic nervous system/physical sickness. Symptoms and signs of krathom withdrawal similar to those of the withdrawal syndrome of opioid substances appear to be present in regular krathom users. The krathom withdrawal intensity is predicted by duration of krathom use, frequency, and daily amount of krathom use. [ABSTRACT FROM AUTHOR]

Background: Despite the legalization of cannabis use for medical purposes in Thailand in February 2019, illicit providers are still widespread and accessible. This study aimed to understand why people still chose to receive medical cannabis treatment or products from unlicensed or illegal providers. The practices of unlicensed or illegal providers in provision of medical cannabis products or treatment services were also examined., Methods: Qualitative in-depth interviews were conducted among medical cannabis providers and users, including 36 unlicensed and 7 licensed providers and 25 users in 2019-2021. Snowball sampling was used to recruit participants until saturation of data was achieved. Interviews included open-ended questions about the providers' practices and attitudes towards medical cannabis. Interviews were recorded and transcribed, and thematic analysis was performed., Results: Overall, six reasons were identified to answer why unlicensed/illicit providers were still popular, including: 1) easy accessibility; 2) familiarity with the unlicensed providers before the legal scheme became available; 3) favorable characters (kind, supportive, non-judgmental) of unlicensed providers; 4) affordable treatment fees; 5) trust in the quality of the medicines; and 6) lack of knowledge and negative attitudes towards cannabis from healthcare professionals. Most providers started their career as medical cannabis providers by using it themselves or with their relatives and being satisfied with the results. They used cannabis products to treat all diseases, including skin, eyes, HIV/AIDS, non-communicable diseases and all kinds of cancers. Additionally, they believed that it was effective, with no or minimal adverse effects., Conclusions: This study suggests that some patients will continue receiving medical cannabis treatment and products from unlicensed or illegal providers. More attention should be paid on increasing the capacity of medical cannabis service systems within public health hospitals, and the certification of unlicensed providers, so as to integrate them into a regulated system., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Assanangkornchai S et al.)
