Summary

This study tests whether a 5-day course of accelerated deep transcranial magnetic stimulation (aTMS) can help adults aged 18–65 quit smoking. Participants receive 4 brain stimulation sessions per day for 5 days. The main goal is to see if the treatment is tolerable and practical, while also tracking smoking abstinence and cravings over 6 months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
accelerated deep transcranial magnetic stimulation (aTMS) using the H4 coil
What this could lead to
If successful, this could offer a fast, non-drug treatment to help people quit smoking by reducing cravings and supporting abstinence.
What could go wrong
This is a small early-phase trial (40 participants) focused on feasibility, not proof of effectiveness. The treatment requires multiple daily sessions, which may be hard to tolerate or complete.
