Brief Summary
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.

Outcome Measures
Primary Outcomes (4)
Percentage of Participants Who Discontinue Accelerated dTMS Due to Side Effects
Tolerability will be assessed by calculating the percentage of participants who discontinue the 5-day accelerated dTMS treatment course due to side effects.
From week 1 day 1, to week 1 day 5 of treatment week.
TMS Experience Questionnaire Acceptability Scores (Units on a Scale)
Acceptability will be assessed using scores on the TMS Experience Questionnaire.
From week 1 day 1, to week 1 day 5 of treatment week.
Percentage of Participants Completing the 5-day Accelerated dTMS Treatment Course
Retention will be measured by the percentage of enrolled participants who complete the full 5-day accelerated dTMS treatment protocol (4 sessions per day for 5 days). The aim is 30 out of 40 participants (75%) completing the course.
From week 1 day 1, to week 5 day 5 of treatment week.
Percentage of Treatment Sessions Attended
Adherence will be measured by calculating the percentages of planned accelerated dTMS treatment sessions attended (20 sessions total over 5 days). For each participant, adherence will be calculated as number of sessions attended divided by 20, and then calculating a mean percentage.
From week 1 day 1, to week 1 day 5 of treatment week.
Secondary Outcomes (5)
The percentage of participants achieving continuous short-term abstinence at follow up
From week 1 day 5 of treatment to week 26.
The percentage of participants achieving continuous long-term abstinence at follow up
From week 1 day 1 of treatment to week 26.
Change in Tobacco Craving Questionnaire-Short Form (TCQ-SF) Total Score (Units on a Scale)
From baseline to week 26.
Change in Dependence Severity (Units on a Scale)
From baseline to week 26.
Change in Daily Cigarette Use (Number of Cigarettes per Day)
From baseline to week 26.
Study Arms (1)
Accelerated Repetitive Transcranial Magnetic Stimulation
EXPERIMENTALBilateral Accelerated Repetitive Transcranial Magnetic Stimulation targeting the insula and prefrontal cortex using H4 coil
Interventions
Accelerated Repetitive Transcranial Magnetic Stimulation (aTMS) is a type of treatment that will be used to target the bilateral insular cortex and prefrontal cortex using the Health Canada-approved H4 coil. The purpose is to test its feasibility on smoking abstinence. While convention rTMS methods involves one session daily over several weeks, aTMS delivers multiple sessions per day. Using the H4 deep aTMS, this study will implement 20 sessions over five consecutive days (four sessions daily).
Eligibility Criteria
You may qualify if:
- Aged 18 years or older;
