Brain scans test if common drug can erase cocaine cravings

This early-stage study is exploring whether the medication methylphenidate (Ritalin) can help weaken the powerful memories and cravings triggered by drug cues in people with cocaine addiction. Researchers will give 51 participants either the medication or a placebo and use brain scans (fMRI) and skin response tests to see how their brains and bodies react to drug-related reminders. The goal is to gather knowledge that could eventually improve therapies to help prevent relapse, but this is not a treatment study and offers no direct benefit to participants.
