The purpose of this study is to learn more about how accelerated theta burst stimulation affects methamphetamine craving and brain activity. Theta burst stimulation is a unique transcranial magnetic stimulation (TMS) paradigm that is efficient and potent.
The purpose of this study is to assess impact of repetitive transcranial magnetic stimulation (rTMS)+Episodic Future Thinking (EFT) vs. sham rTMS+EFT on delay discounting and methamphetamine (MA) demand, on vividness of future positive events during EFT training and on frequency of episodic thinking during the week following EFT training
The goal of this clinical trial is to learn whether it is possible to use intramuscular (IM) ketamine in combination with psychotherapy to treat moderate-to-severe methamphetamine use disorder (MeUD) in publicly insured patients with or at-risk for HIV disease. The main questions it aims to answer are: * Do publicly insured patients find ketamine-assisted psychotherapy feasible and acceptable as a potential treatment for MeUD? * Is IM ketamine safe and tolerable among patients with MeUD? Participants will: * Receive 3 monitored doses of IM ketamine * Have 3 preparation and 4 integration psychotherapy visits * Report their daily amounts of methamphetamine used prior to, during, and up to 3 months following the intervention
The goal of this clinical trial is to use contingency management (CM) as an intervention tool to address methamphetamine use. The main objectives are to: * Gather effectiveness data on a pilot a CM program for participants in Hawaii who use methamphetamine following hospitalization due to traumatic injury * To assess participant perspectives on engaging with a CM program based at a Level 1 Trauma Center. Researches will assess both patient-reported and biologically-confirmed medium-term program effectiveness and conduct qualitative interviews with participants post-program. Participants will: * Visit a follow-up clinic up to three times per week to complete urinalysis following discharge from the trauma unit * Complete Treatment Effectiveness Assessments at 6 and 12-weeks * Engage in a qualitative interview at the end of the CM program
This study aims to determine whether treatment response with IV ketamine is superior to treatment response with IV midazolam in adults with moderate to severe MUD. The study design is a 12-week randomized, double-blind, controlled trial comparing intravenous (IV) ketamine against IV midazolam, delivered over six weeks in 120 adults with moderate to severe methamphetamine use disorder (MUD).
In this project, the investigators examine behavior and associated brain activity during explore-exploit decision-making tasks performed pre- and post-modulation of affective state using autobiographical memory recall. The investigators hypothesize that a positive memory recall will reduce negative affective state, reduce explore-exploit biases and normalize the associated brain activity. The investigators propose a randomized double-blind, sham-controlled trial of positive autobiographical memory recall with 80 adults (n=40 per arm) with methamphetamine use disorder (MUD) currently involved in abstinence only treatment centers.
This study is using Transcranial Magnetic Stimulation (TMS) to determine if interventional psychiatry treatment can help with the treatment of Methamphetamine Use Disorder. Individuals with Methamphetamine Use Disorder will receive 5 consecutive TMS treatment sessions based off of randomization. Participants will be randomized to one of two groups. TMS treatment arm or sham-TMS arm.
This project will evaluate the ability of Mirtazapine (MZP), a pharmacologically unique medication with a growing body of evidence to support its efficacy and safety for the treatment of methamphetamine (MA) use among medication for opioid use disorder (MOUD) patients, to significantly decrease MA use and related health-impairing behaviors. MZP has already successfully been used in the treatment of methamphetamine (detailed further below and in the Appendices). The investigators hypothesize that those assigned to the MZP plus treatment as usual (TAU) MZP+TAU arm will demonstrate significantly increased rates of biochemically verified abstinence from MA and other substances of abuse and experience improvements in health impairing behaviors relative to the placebo (PLO)+TAU arm across the 10-week treatment and follow-up periods.
The investigators will evaluate the effects of an accelerated Transcranial Magnetic Stimulation (TMS) protocol of the left dorsolateral prefrontal cortex (DLPFC) for moderate to severe methamphetamine use disorder. This is a randomized parallel group design to assess feasibility and safety, evaluate efficacy (use, craving) and identify magnetic resonance imaging (resting state and cue craving) associated with group/outcomes.
The primary objective of this study is to evaluate the efficacy of extended release naltrexone plus bupropion XL (XR-NTX/BUP-XL) compared to matched injectable and oral placebo (iPLB/oPLB) in reducing methamphetamine (MA) use in individuals with moderate or severe methamphetamine use disorder (MUD) seeking to stop or reduce MA use.
