Can a sound wave calm addiction? ultrasound targets the Brain's craving center

This trial tests whether a single session of low-intensity focused ultrasound aimed at a brain region linked to reward and craving can safely reduce substance cravings and prevent relapse in people with severe opioid or amphetamine use disorder. Sixty participants will receive the ultrasound treatment and be followed for up to two years to track craving levels, drug use, and mental health. The goal is to see if this non-invasive approach can help control addiction when standard treatments are not enough.
