Objectives: Kratom (Mitragyna speciosa Korth.), an indigenous medicinal plant, has been widely used as a traditional remedy in Southeast Asia. However, its combined consumption with other substances has received scarce attention. This study investigates the use of kratom among adults with a history of using heroin and methamphetamine in Malaysia.

Methods: A total of 332 patients who were mandated to undergo drug rehabilitation participated in this cross-sectional study. The study data were collected through face-to-face interviews using a semi-structured questionnaire.

Results: The majority were males (95%, n = 314/332) and Malays (98%, n = 325/332) with a mean age of 32.3 years (SD = 9.16). Over two thirds of the respondents used kratom to alleviate heroin withdrawal symptoms and to reduce methamphetamine intake; 59% used it as a substitute for heroin and methamphetamine. A similar proportion used kratom to reduce heroin intake (58%), while only 15% used it for its euphoric effects. Multivariate analysis showed that previous attendees of government rehabilitation programs had lower odds of using kratom as a heroin substitute.

Conclusions: The potential of kratom to alleviate heroin withdrawal symptoms, and to reduce methamphetamine and heroin intake, among people who co-use heroin and methamphetamine warrants further research.

Disrupting Heroin-Associated Memory Reconsolidation through Actin Polymerization Inhibition in the Nucleus Accumbens Core.

Int J Neuropsychopharmacol

December 2024

National Clinical Research Center for Geriatric Disorders, Xiangya Hospital, Central South University, Changsha, China.

Background: Understanding drug addiction as a disorder of maladaptive learning, where drug-associated or environmental cues trigger drug cravings and seeking, is crucial for developing effective treatments. Actin polymerization, a biochemical process, plays a crucial role in drug-related memory formation, particularly evident in conditioned place preference (CPP) paradigms involving drugs like morphine and methamphetamine. However, the role of actin polymerization in the reconsolidation of heroin-associated memories remains understudied.

Drug addiction often correlates with criminal behavior. When investigating criminal behavior among individuals grappling with drug addiction, it becomes crucial to scrutinize the influence of dopamine. Substances such as heroin, morphine, methamphetamine and other drugs can cause abnormal dopamine secretion when people are addicted to them, which promotes changes in the brain's reward circuit and emotional balance, thereby increasing susceptibility to criminal behavior.

  • Myocardial dissection is a rare but serious complication of ischaemic heart disease, characterized by a haematoma forming within the cardiac muscle, often triggered by factors such as increased wall tension and reduced tensile strength.
  • A case study highlights a 37-year-old male, who developed myocardial dissection following an ST elevation infarction after years of substance abuse, including heroin and methamphetamines, which might be linked to his condition.
  • The patient presented with symptoms of heart failure, and diagnostic tests revealed severe heart dysfunction and a mass in the heart, leading to treatment with diuretics and medical therapy instead of surgery due to high operative risk.

Peer-assisted telemedicine for hepatitis C in people who use drugs: A randomized controlled trial.

Clin Infect Dis

November 2024

Department of Medicine, Division of General Internal Medicine & Geriatrics, Section of Addiction Medicine, Oregon Health & Science University, Portland, OR.

Background: Hepatitis C virus (HCV) elimination requires treating people who use drugs (PWUD), yet fewer than 10% of PWUD in the United States access HCV treatment and access is especially limited in rural communities.

Methods: We randomized PWUD with HCV viremia and past 90-day injection drug or non-prescribed opioid use in seven rural Oregon counties to peer-assisted telemedicine HCV treatment (TeleHCV) versus peer-assisted referral to local providers (enhanced usual care; EUC). Peers supported screening and pre-treatment laboratory evaluation for all participants and facilitated telemedicine visits, medication delivery, and adherence for TeleHCV participants.

  • This study investigates the patterns of amphetamine-type stimulant (ATS) use and high-risk behaviors among adults in Manipur, India, revealing that the majority of users engage in daily use and dependence on substances.
  • Most participants reported significant health issues related to ATS, including a tendency to inject drugs and risky sexual behavior, such as unprotected sex.
  • The findings indicate a need for targeted strategies in India to address and reduce ATS use and its associated physical and psychological consequences.
