Zapping the brain to fight drug cravings: small study shows promise
NCT ID NCT06454474
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a brain stimulation technique called closed-loop tACS in 21 people with methamphetamine addiction. The device uses brain wave patterns to deliver targeted electrical stimulation aimed at reducing cravings. Researchers measured craving levels and impulse control before and after the intervention. The trial is complete but small, so results are preliminary.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
closed-loop transcranial alternating current stimulation (tACS) device
What this could lead to
If it works, this could point toward a non-drug method to reduce cravings and improve self-control in people with amphetamine addiction.
What could go wrong
This is a very small, early study with only 21 participants and no control group. Results may not apply to everyone, and the effect on long-term addiction is unknown.
