Accelerated dTMS Smoking Cessation

The goal of this clinical trial is to examine whether a 5-day course of bilateral accelerated deep transcranial magnetic stimulation (aTMS) is a feasible treatment to help adults (18-65) with Tobacco Use Disorder to quit smoking. This study aims to enroll 30-40 participants and will examine treatment tolerability, treatment acceptability, participant retention, and adherence to scheduled treatment sessions. There are two key objectives and hypotheses: Objective 1: To evaluate whether a 1-week course of bilateral aTMS (4 sessions per day for 5 days) is feasible and tolerable as a smoking cessation treatment. Hypothesis 1: Feasibility will be demonstrated by acceptable tolerability, acceptability, retention, and adherence, with a practical target of 30 out of 40 participants completing the treatment. Objective 2: To explore how aTMS affects smoking outcomes, including: * Point-prevalence abstinence at end of treatment and at Weeks 3, 5, and 9. * Prolonged/continuous abstinence at Weeks 13 and 26. * Craving, cigarettes per day, and dependence severity. Hypothesis 2: Participants will show improvements on these outcomes from post-treatment through follow-up.
