Researchers want to learn whether rTMS may be an effective treatment for Veterans with stimulant use disorder, including addiction to methamphetamine, amphetamine, or cocaine.

• A non-invasive treatment that has been FDA-cleared to treat depression since 2008. 
• Uses a device placed against the head to deliver magnetic pulses that stimulate specific areas of the brain.

• Complete urine testing during the in-person study visits.
• Complete follow-up clinical assessment calls once a month for 3 months after the rTMS sessions.
• If you receive the placebo treatment, you may have the option to receive active rTMS after completing the study procedures.

Participants can receive $280 for completing the study. An additional $120 is available for completing optional MRI scans. Travel expenses to and from the Palo Alto VA may also be reimbursed.
