Article Synopsis
  • A study explored the link between kratom use and aggression among male methamphetamine (METH) users, involving 403 participants and various clinical measures.
  • No significant differences in aggression levels were found between METH users and those with a history of kratom use, although two distinct clusters of users emerged based on their kratom consumption patterns.
  • In Cluster 1, higher kratom use correlated with increased aggression, while in Cluster 2, lower frequency of kratom use acted as a protective factor against aggression, suggesting that moderate kratom use may reduce aggression in some METH users.

In solid waste management, pollution-free disposal of leaf waste in urban areas is still not standardized and adopted. According to the World Bank report, 57% of wastes generated in South East Asia are consisted of food and green waste, which can be recycled into valuable bio-compost. The present study shows a method of leaf litter waste management by composting it using essential microbe (EM) method.

This Letter to the Editor is a response to Broyan and colleagues who recently published a Case Report presenting data on 28 patients in the United States who identified kratom as their primary substance of use and who were subsequently induced on buprenorphine/naloxone for a reported diagnosis of kratom use disorder. We applaud the authors for helping to advance the science on kratom and recognize the difficulties in conducting kratom-related clinical assessment and research. However, a number of inconsistences and generalizations were identified in this Case Report, which also lacked some critical context.
