case_images: Protocol timeline separated by weeks. The participant described in this report received 5 days of iTBS before discontinuing the intervention and moving to the follow-up phase. He received contingency management as the treatment as usual throughout his participation (starting when iTBS was initiated). fMRI measures were acquired prior to iTBS initiation and before and after the iTBS sessions on the first day of iTBS. No additional experimental fMRI scans were completed with this participant because he was lost to follow-up.

case_images: He waited approximately one year while we obtained FDA clearance to proceed with the RCT (see  Figure 1  for the study timeline). During this trial, repeated functional magnetic resonance imaging (fMRI) scans are conducted to elucidate changes in neural functioning due to the iTBS intervention (see  Figure 1  for study timeline). In the week prior to the treatment phase of the study, the participant completed a characterization phase, which consisted of two MRI scans, multiple questionnaires, and bench assessments, as well as an iTBS toleration session to familiarize him with the study procedures and the sensations of the iTBS condition to which he was randomly assigned (week 1 of  Figure 1 ).
case_images: Progression of participant participation in the study relative to their first iTBS treatment day (T0). Tremor first appeared and was evaluated 6 days after the first iTBS treatment day (T+6).

case_images: Further clinical workup was pursued, which included an MRI with contrast and a magnetic resonance angiography (MRA; both unremarkable), and an EEG was ordered but could not be completed before the tremor had resolved after 28 days, study day 34 (see  Figure 2 ). He was 2 weeks abstinent from cocaine at that time and 2 weeks tremor-free when he stopped responding to repeated contact attempts ( Figure 2 ).
