Background: Methamphetamine dependence has become a significant problem, but methamphetamine withdrawal symptoms have not been well studied.
Methods: This prospective observational pilot study was designed to examine withdrawal symptoms, mood, anxiety, cognitive function, and subjective measures of sleep over a 4-week period in six patients entering residential treatment for methamphetamine dependence.
Results: Methamphetamine withdrawal symptoms, mood, and anxiety symptoms all resolve fairly quickly within 2 weeks of cessation of methamphetamine. Sleep was disrupted over the course of the 4-week study. No clinically significant alterations in blood pressure or heart rate were identified. This study did not demonstrate any alterations in cognitive function over the 4 weeks of the residential stay.
Conclusions: This pilot study points toward the need for a double-blind, placebo-controlled amphetamine withdrawal paradigm in humans where changes in sleep, cognitive function, and withdrawal measures can be explored more fully.
Scientific Significance: This study extends the literature by pointing toward a methamphetamine withdrawal syndrome that includes alterations in measures of sleep quality and refreshed sleep, early improvement in depression and anxiety symptoms, most striking during the first week, but persisting into the second week.

Background: Xylazine is a α2-adrenergic receptor agonist, used for sedation in veterinary contexts. Although it is increasingly found in overdose deaths across North America, the clinical management of xylazine-involved overdoses has not been extensively studied, especially in community-based harm reduction settings. Here we present a clinical series of xylazine-involved overdose and share the clinical approach and lessons learned by a community overdose response team in Tijuana, Mexico amidst the arrival of xylazine.

Methamphetamine (MA) dependence leads to severe physical and psychological issues. Current treatments, including psychosocial therapies and residential rehabilitation, face limitations such as high relapse rates, cost, and accessibility issues. As a result, there is an urgent need for novel approaches to treat MA dependence that are effective, affordable, and accessible to patients.

Acute high-intensity interval training (HIIT) has cognitive benefits in individuals with methamphetamine use disorder (MUD), yet it remains largely unknown the benefits of long-term HIIT on emotional conflict control and its neural mechanism in individuals with MUD. The current study conducted a 36-week low-volume HIIT intervention to investigate the effects of HIIT on emotional conflict control in males with MUD and their prefrontal cortex (PFC) activation. This study was a sub-study of the Study for Rehabilitation Training Model Construction and Training Effect of High Intensity Compound Exercise Prescription.

Article Synopsis
- - Evidence shows that methamphetamine users face a much higher risk of developing psychosis, with a study examining 2,098 individuals revealing that 12.7% exhibited methamphetamine-associated psychosis (MAP).
- - Various sociodemographic and clinical factors were analyzed; these included older age, early onset of substance use, frequent meth use, single marital status, lower education levels, and increased anxiety among those with MAP.
- - The study highlights that while identified factors reflect immediate conditions upon admission, they can help in understanding the contextual elements linked to MAP in outpatient settings.

Aim: Methamphetamine use disorders (MUDs) cause widespread disruptions in metabolomic and immunologic processes, highlighting the need for new therapeutic approaches. The purpose of this study was to find molecular and neuroimaging biomarkers for methamphetamine addiction.
Methods: In this study, we recruited 231 patients with MUD at varying stages of withdrawal and 40 healthy controls to quantify the blood levels of 52 molecules using enzyme-linked immunosorbent assay.
