Brief Summary
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.

Study Arms (2)
Sham TMS
PLACEBO COMPARATORParticipants have baseline assessments/evaluation, are admitted to the inpatient research unit, randomized via permuted block design to 5 days of sham TMS, and then have weekly study visits for the next 12 weeks.
Active TMS
EXPERIMENTALParticipants have baseline assessments/evaluation, are admitted to the inpatient research unit, randomized via permuted block design to 5 days of active TMS, and then have weekly study visits for the next 12 weeks.
Interventions
The TMS Cool-B65 A/P coil on its placebo side delivers electrical stimulation to the scalp (e.g., mimicking sensations associated with real stimulation) but does not provide magnetic stimulation to the targeted cortical structure.
The TMS Cool-B65 A/P coil delivers magnetic stimulation to targeted cortical structure.
Eligibility Criteria
You may qualify if:
- Age 21-65 years inclusive;
- Meets DSM-5 criteria for past-year moderate or severe methamphetamine use disorder;
- By Timeline Follow Back endorses at least 10 days of methamphetamine use out of the last month;
- Provides a urine drug screen positive for methamphetamine;
- Able to provide informed consent;
- No change in current psychiatric medication regimen, or medication free, for at least 4 weeks prior to study entry;
- Adequate English proficiency for study consent, and completion of the study instruments.
You may not qualify if:
- Lifetime non-substance-induced psychotic disorders, schizophrenia, schizoaffective disorder or bipolar disorder defined by DSM-5;
- Current diagnosis of DSM-5 drug use disorder other than stimulant, cannabis or nicotine use disorder;
- Non-substance-induced manic episode within the past 3 years or major depressive episode in the past year;
- Current clinically significant neurological disorder or medical illness, including history of seizures, cardiovascular disease/cardiac event, which in the opinion of the study physician would make study participation unsafe;
- Presence of a clinically significant abnormality on baseline MRI;
- Inability to have an MRI;
- Currently breastfeeding, is currently pregnant or lack of use of effective contraception in women of childbearing age, as assessed by urine pregnancy test and self-report (participants will consent to continue effective contraceptives during the study);
- Active criminal justice involvement (i.e., any unresolved legal problems that could jeopardize continuation or completion of the study);
- History of head injury with loss of consciousness for more than 15 minutes;
- Diagnosis of dementia;
- Prescribed benzodiazepines or anticonvulsants;
- Currently enrolled in formal substance use disorder treatment;
- Metal implants or non-removable metal objects above the waist;
- Lifetime history of prior clinical treatment with TMS;
- Serious risk of suicide or homicide;
- +3 more criteria
