If you’ve tried patches, gum, and prescription medications without success, you may wonder whether a device that stimulates the brain can actually help you quit smoking. I want to walk you through how FDA-cleared deep TMS targets the craving circuits behind nicotine addiction, what a treatment course actually involves, and how it stacks up against other quit options, especially if medication hasn’t worked for you or isn’t something your body can tolerate.
Quitting smoking is rarely a simple matter of deciding to stop and sticking with it. Nicotine changes the way your brain processes reward, and two regions in particular get rewired over years of use: the insula and the prefrontal cortex. The insula tracks internal body states and plays a major role in what researchers call interoception, essentially your brain’s sense of what’s happening inside you. In smokers, the insula becomes tightly linked to craving signals, so a stressful moment, a cup of coffee, or even the sight of a lighter can trigger an urge that feels urgent and physical rather than optional.
This is where a lot of well-meaning advice falls short. Telling someone to “just use willpower” ignores the fact that craving circuits can override the very part of the brain responsible for planning and self-control. The prefrontal cortex is supposed to weigh long-term goals against short-term impulses, but in an addicted brain, the insula’s signal often wins that argument. That’s not a character flaw. It’s a documented pattern of altered brain activity, and it helps explain why so many people who genuinely want to quit end up relapsing within weeks of their last cigarette.
Behavioral strategies, support groups, and counseling all have value, and I’d never suggest skipping them. But they mostly work at the level of conscious decision-making. They don’t directly change the activity of the deeper brain structures driving the urge to smoke in the first place. That gap is exactly why a treatment capable of reaching the insula and prefrontal regions directly, without relying on medication, has become such an important option for people who’ve tried everything else.
Deep TMS is a form of addiction neuromodulation, meaning it uses magnetic pulses to change activity levels in specific brain circuits rather than introducing a drug into your system. You may already be familiar with standard TMS as a depression treatment, which uses a figure-8 shaped coil to stimulate surface-level regions of the prefrontal cortex. Smoking cessation TMS works differently. It relies on a specially designed coil, known as the H4 coil, built to reach deeper structures, including the insula, that standard coils simply can’t access with the same precision.
The H4 coil is part of the BrainsWay Deep TMS system, and its geometry allows the magnetic field to extend further into the brain while still targeting a defined region rather than diffusing broadly. This matters because the insula sits deeper in the brain than the outer cortical regions targeted in depression protocols. The FDA clearance for smoking cessation specifically reflects this insula-prefrontal targeting, since that circuit is where craving and the urge to smoke appear to be generated and reinforced.
What draws many people to this approach is that it doesn’t involve taking anything. If you’re looking to quit smoking without medication, whether by personal preference or because you’ve had a bad reaction to varenicline or bupropion in the past, deep TMS offers a mechanism that works through brain stimulation rather than pharmacology. There’s no interaction with other medications to worry about, no systemic side effects like nausea or mood changes that some people experience with quit-smoking drugs, and no need to taper on or off a prescription.
I think of it this way: nicotine replacement and medication both work by changing the chemistry circulating through your body. Deep TMS instead works by changing the pattern of activity in the specific brain regions responsible for the craving itself. That’s a meaningfully different approach, and it’s one reason it has become a serious option for people who’ve cycled through other quit methods without lasting success.
One detail that surprises a lot of people is that a smoking cessation TMS session doesn’t start with the magnet. It starts with a deliberate craving trigger. Before stimulation begins, you’ll go through a brief cue provocation step, where you’re shown smoking-related images or asked to hold and smell items associated with your habit, like an unlit cigarette. This isn’t an oversight or a strange add-on. It’s a core part of the protocol, designed to activate your craving circuits right before the magnetic pulses are delivered, so the stimulation reaches the insula and prefrontal regions while they’re actively engaged in the craving response.
Once the cue exposure has done its job, you’ll sit comfortably in a treatment chair while the H4 coil, built into a helmet-like device, is positioned against your scalp. You stay awake and alert throughout, there’s no sedation or anesthesia involved, and most sessions run about 15 to 20 minutes. You’ll feel a tapping or clicking sensation on your scalp during stimulation, which most patients describe as mildly uncomfortable at first and easy to tolerate after the first session or two.
A full course typically involves daily sessions over several weeks, though the exact schedule depends on your individual history with smoking, your quit goals, and how you’re responding along the way. This isn’t a one-and-done treatment. Craving circuits took years to form, and meaningfully changing that pattern generally requires a consistent course rather than a single visit. If you’re curious about how progress tends to build over the course of TMS treatment more broadly, I’d point you to our page on what results look like over a course of TMS, which covers how improvement typically unfolds across weeks rather than days.
The FDA clearance for deep TMS as a smoking cessation aid was based on a randomized, controlled clinical trial comparing active stimulation with a sham version of the treatment. In that pivotal study, researchers found that participants receiving active deep TMS had meaningfully higher continuous quit rates by the end of the treatment course compared with those receiving sham stimulation. Continuous quit rate refers to the percentage of participants who remained smoke-free for a defined stretch of time, rather than simply reporting a single smoke-free day.
I want to be careful here, because exact percentages from that trial and from any newer published research can shift as more data comes in, and I don’t want to hand you a number that’s gone stale by the time you read this. What I can tell you with confidence is that the direction of the finding was clear enough to support FDA clearance, which is a meaningful bar to clear for any addiction treatment device. If you want the current published figures, I’d rather walk through them with you directly during a consultation, using the most up-to-date data from BrainsWay’s labeling and peer-reviewed sources, than print a statistic here that might be outdated by next year.
What matters more for most patients is understanding that deep TMS is not a guarantee and works best as one part of a broader quit plan. Results vary based on how long you’ve smoked, how many quit attempts you’ve made before, whether you’re pairing treatment with counseling or a support program, and your individual brain physiology. Some patients notice a real drop in craving intensity within the first couple of weeks of sessions. Others need the full course before they feel a shift they’d describe as meaningful. Neither pattern is unusual, and neither means the treatment isn’t working.
Nicotine replacement therapy, whether in the form of patches, gum, or lozenges, works by supplying a controlled dose of nicotine to ease withdrawal symptoms while you break the behavioral habit of smoking. It’s helpful for many people, but it doesn’t address the underlying craving circuitry in the insula and prefrontal cortex. Once you stop using the replacement product, the craving pattern that was there before treatment is often still there, which is part of why relapse rates after nicotine replacement alone remain high.
Prescription options like varenicline and bupropion take a different approach, acting on neurotransmitter systems in the brain to reduce the reward associated with smoking or ease withdrawal. Both can be effective, but both also carry real trade-offs. Varenicline has been associated with vivid dreams, nausea, and in some patients mood changes that make it a poor fit. Bupropion carries seizure risk considerations and isn’t appropriate for everyone, particularly people with a history of certain psychiatric or neurological conditions. For patients managing other conditions we treat here, like mood disorders or a history of concussion, these medication interactions and contraindications can rule out pharmacological options entirely.
Deep TMS occupies a different space. Because it doesn’t rely on systemic medication, it’s often a reasonable option for people who’ve relapsed after trying nicotine replacement or medication, or who simply can’t take those medications safely. It also doesn’t preclude combining approaches. Some patients use TMS alongside counseling or even alongside a tapering nicotine replacement plan, under their provider’s guidance. If you’re interested in how brain stimulation compares across different neuromodulation approaches we offer, our page on TMS and related protocols gives more context on how these treatments are structured and delivered.
No quit method, including deep TMS, comes with a promise that you’ll never smoke again. Relapse risk exists after any cessation approach, and it’s worth planning for that reality rather than being caught off guard by it. Some patients benefit from maintenance or booster sessions after completing an initial course, particularly if they notice cravings creeping back during a high-stress period or after a long gap without cigarettes. This isn’t a sign that the initial treatment failed. It’s a recognition that addiction recovery, like recovery from many chronic conditions, sometimes needs ongoing reinforcement.
Pairing deep TMS with behavioral support, whether that’s individual counseling, a structured cessation program, or peer support, tends to improve long-term outcomes. The brain stimulation addresses the craving circuitry, but the habits, routines, and social patterns built around smoking often need their own attention. Addressing both pieces together gives you a stronger foundation than relying on either one alone.
I’d also encourage patience with the process itself. Craving reduction with this protocol typically builds gradually across the treatment course rather than showing up dramatically after one or two sessions. If you don’t feel a major shift in the first week, that doesn’t mean the treatment isn’t working. It usually means you’re partway through a process that needs the full course to show its effect. Staying consistent with your scheduled sessions gives the treatment the best chance to do what it’s designed to do.
