Participants in this arm will undergo all study procedures including consent; pre-, during, and post-psychological assessments; pre- and post- MRI and fMRI; 16 treatments of dual target TMS over a 4-week period; and substance use-related assessments to include substance use, withdrawal symptoms, and cravings to use. This arm will receive the dorsolateral prefrontal cortex stimulation first.
Transcranial Magnetic Stimulation: Participants will undergo 16 treatments consisting of intermittent theta burst stimulation targeting the dorsolateral prefrontal cortex and continuous theta burst stimulation targeting the medial prefrontal cortex, over a 4-week period that coincides with psychosocial treatment for methamphetamine use disorder.

Summary score of discounting rate. Scores range from 0.00016 to 0.5, with smaller values indicating a lack of discounting and preference for delayed rewards, and higher values indicating strong discounting and preference for immediate rewards. Higher scores are associated with addictive behaviors. The log of K is reported due to its skewed nature. Values are estimated from a mixed model.

Estimated change per day in number of days of stimulant use in the last week (self-reported) from mixed models. Measured as number of days of methamphetamine use because methamphetamine and other stimulant use were reported separately, and it was not clear if these were on the same or different days. The vast majority of subjects reported using only methamphetamine.

The Brief Substance Craving Scale Score used was the summary score of intensity, frequency and length of cravings in the last 24 hours. Scores based on stimulant craving responses and range from 0-12 with higher scores indicating more craving. Scores are least squared means from mixed models of actual measures, without last observation carried forward or any imputation. Change in score per day estimated from a mixed model.
