Zapping the brain to kick the habit: new trial tests rTMS for smoking cessation
NCT ID NCT04903028
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a non-invasive brain stimulation technique called rTMS can help people stop smoking. Researchers will use MRI scans to guide the stimulation to brain areas involved in craving and self-control. The trial involves 64 smokers who will receive either real or sham rTMS, and their quit rates and brain activity will be measured over several weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- repetitive transcranial magnetic stimulation (rTMS)
- What this could lead to
- If successful, this could offer a non-drug, brain-based approach to help people quit smoking by reducing cravings and improving self-control.
- What could go wrong
- This is an early-stage study with only 64 participants, so results may not apply to everyone. The treatment is non-invasive but may cause mild side effects like headache or scalp discomfort.

Exclusion Criteria * Current moderate to severe substance use of any psychoactive substances other than nicotine or caffeine, as defined by DSM-V criteria. * Contraindications to MRI (e.g., presence of metal in the skull, orbital or intracranial cavity, or having claustrophobia). * Contraindication to rTMS. * History of autoimmune, endocrine, viral, or vascular disorders affecting the brain. * History or MRI evidence of neurological disorder that would lead to local or diffuse brain lesions or significant physical impairment. * Unstable cardiac disease, uncontrolled hypertension, severe renal or liver insufficiency, or sleep apnea. * Lifetime history of major Axis I disorders such as: bipolar affective disorder (BPAD), schizophrenia, post-traumatic stress disorder (PTSD), dementia, suicidal ideation or major depression. * Self-report of \>21 standard alcohol drinks per week in any week in the 30 days prior to screening. * Use of other forms of nicotine delivery, such as nicotine patches, electronic cigarettes, gum, nasal spray, inhalers, and nicotine lozenges. * Use of other tobacco products, including cigars, cigarillos, chew, snuff, and pouches/snus. * Previous treatment with TMS.
