Early or partial results. Treat as a signal, not a conclusion.
This is a narrative review of the methamphetamine misuse literature covering neurobiology, epidemiology, and public health burden. It synthesizes known mechanisms of neurotoxicity and dependency but reports no original data, effect sizes, or comparative evidence; it serves primarily to restate the problem and existing knowledge gaps.
Narrative literature review. Published literature on methamphetamine use, misuse, neurotoxicity, and dependency; no clinical cohort enrolled.
Methamphetamine induces severe oxidative stress, dopaminergic neurodegeneration, and long-lasting cognitive impairment Dependence is reinforced by rapid dopamine release and neuroadaptive changes in reward circuitry Societal consequences include increased rates of crime, psychiatric comorbidities, infectious disease transmission, and economic loss
No FDA-approved pharmacological treatment for methamphetamine dependence exists despite ongoing research
This review does not provide actionable clinical evidence or new treatment options. It underscores the absence of approved pharmacological therapies and the need for prevention and harm reduction strategies, but offers no novel guidance for clinical practice.
This is a narrative literature review synthesizing existing evidence on methamphetamine neurotoxicity and epidemiology, without new primary data, original analysis, or actionable clinical recommendations beyond restating known gaps.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Background Methamphetamine use has surged in recent decades, posing significant threats to neurological health and societal stability. Its highly addictive nature, low cost, and widespread availability have led to a global public health concern.Objective This review aims to explore the contemporary patterns of methamphetamine use and misuse, with a focus on its neurotoxic mechanisms, dependency risks, and the social and economic burdens it imposes.Methods A comprehensive literature review was conducted using peer-reviewed sources from databases such as PubMed, Scopus, and Web of Science, covering studies from the past two decades on methamphetamine-related neurobiology, epidemiology, and public health outcomes.Results Methamphetamine induces severe oxidative stress, dopaminergic neurodegeneration, and long-lasting cognitive impairment. Dependence is reinforced by rapid dopamine release and neuroadaptive changes in reward circuitry. Societal consequences include increased rates of crime, psychiatric comorbidities, infectious disease transmission, and economic loss. Despite ongoing research, there is still no FDA-approved pharmacological treatment for methamphetamine dependence.Conclusion The global rise in methamphetamine misuse necessitates urgent attention to neurobiological, therapeutic, and policy-level interventions. Public health strategies must prioritize early prevention, harm reduction, and the development of evidence-based treatments.
