I started noticing a pattern before I understood the diagnosis. Not in a detox unit or smoking cessation clinic, but in otherwise healthy young men sitting in my outpatient office — high school athletes, college students, gym-goers, kids who looked like they should have been discussing protein intake and fantasy football instead of cardiac symptoms.
One was a 17-year-old lacrosse player referred to me after repeated episodes of palpitations during practice. He had intermittent chest tightness, elevated blood pressure, and enough anxiety surrounding the symptoms that his parents feared an underlying arrhythmia. His ECG was normal. Echocardiogram normal. Labs normal.
Another was a 20-year-old college student who arrived at my clinic convinced he was developing panic disorder. His resting heart rate hovered in the 110s, and his blood pressure was consistently elevated. He described feeling “amped up all the time,” sleeping poorly, and increasingly waking at night with his heart racing.
Neither smoked cigarettes nor vaped heavily, but both used nicotine pouches constantly.
One was going through nearly a can a day of high-strength 17 mg nicotine pouches during school, workouts, driving, and gaming sessions. The other kept his “lippers” tucked in almost continuously throughout the day because, in his words, “they’re cleaner than vaping.”
When both significantly reduced or stopped their nicotine pouch habit, the cardiovascular symptoms disappeared entirely.
As an addiction psychiatrist, I have spent years treating alcohol, opioids, benzodiazepines, stimulants, and nicotine dependence. But increasingly, nicotine pouches are emerging as one of the more clinically deceptive substances I encounter — largely because they carry none of the traditional markers of addiction: no smoke, no lingering smell, and no visible social stigma. Just small white pouches marketed with the aesthetic and language of wellness culture.
Modern nicotine pouches resemble minimalist tech accessories more than tobacco products. The packaging is sleek. The flavors sound like energy drinks or gum. They fit neatly into gym bags and backpack pockets. Many young users genuinely believe they are engaging in a relatively benign habit.
To be fair, compared to cigarettes, nicotine pouches probably are less harmful in important ways. They avoid combustion and many of the carcinogens associated with tobacco smoke. That matters because perception drives behavior. In a recent study, approximately 73% of cigarette smokers reported that “less perceived harm” was their primary reason for starting to use nicotine pouches.
But the problem is that “safer than cigarettes” has become diluted to mean “safe.” Those are not remotely the same thing. There is still risk involved.
What is most surprising is not just how many adolescents and young men (and the data confirms it is mostly young men) are using nicotine pouches, but how little they understand the risks of nicotine exposure itself. Many assume they are consuming less nicotine than cigarettes. In reality, the opposite is often true.
Traditional cigarettes contain roughly 10 mg to 12 mg of nicotine, though users only absorb about 1mg to 2 mg of that nicotine. Nicotine pouches, however, commonly contain anywhere from 3 mg to 12 mg, with highly efficient absorption of almost all of that nicotine content directly through the oral mucosa. Independent analyses have identified nicotine pouch products containing nicotine levels far exceeding these advertised amounts.
This matters because nicotine is not pharmacologically neutral simply because it is tobacco-free. As a potent central nervous system stimulant, nicotine increases blood pressure and heart rate, putting long-term strain on the cardiovascular system.
There is something else that contributes to the subtly addictive nature of nicotine pouches: greater ease of use. Unlike cigarettes, nicotine pouches are immune to many of the natural societal interruptions and stigma that historically limited nicotine exposure. Smoking requires going outside, stepping away, or finishing a discrete session. Cigarettes eventually burn out. You can’t smoke a cigarette in a restaurant or a bar, in a public building, during an athletic event, in a formal work meeting, or even on a Zoom call. You can (and people absolutely do) use nicotine pouches in all the above scenarios.
In other words, nicotine pouches have no natural stopping point. The nicotine delivery system becomes continuous. Many of my younger patients use them while driving, studying, gaming, exercising, sitting in class, or even falling asleep. The exposure shifts from episodic to nearly sustained.
Clinically, the effects are not subtle. As a potent sympathomimetic stimulant, nicotine activates the sympathetic nervous system, increases catecholamine release, and causes vasoconstriction. Multiple recent studies on nicotine pouches have demonstrated what I’m seeing in real time: dramatic increases in heart rate, arterial stiffness, and blood pressure, particularly with the higher-dose products.
Young patients often interpret these symptoms psychologically before recognizing the stimulant effect. They describe panic attacks, restlessness, chest palpitations, sleep disruption, and overall increased anxiety. And because the product lacks smoke or vapor, many do not initially identify nicotine as the culprit.
That diagnostic blind spot is what concerns me most. Because clinicians can’t readily see the habit or damage, we often fail to ask about it, discuss it, or even consider it as a possible underlying cause.
There is a tendency in public discourse to separate nicotine from harm entirely. While nicotine itself may not be the primary carcinogenic driver of cigarette-related cancers, it remains a highly addictive cardiovascular stimulant with meaningful physiologic effects. The American Heart Association recently reiterated that smokeless oral nicotine products still carry cardiovascular risks and addictive potential.
The other issue is developmental. Adolescent and young adult brains are uniquely vulnerable to nicotine dependence. Early high-dose nicotine exposure strengthens reinforcement pathways rapidly, increasing the likelihood of sustained long-term addiction. Concerningly, emerging data already suggest rising awareness and use of nicotine pouches among high school and college populations.
Which brings us back to those clinical vignettes. Neither patient initially believed nicotine pouches could explain their symptoms: they suspected anxiety and cardiac conditions. Both were shocked to learn that the “healthier alternative” they were using continuously throughout the day might itself be driving the symptoms they found so frightening.
That is the paradox of nicotine pouches. They may reduce some carcinogenic harms of smoking, but they also risk normalizing high-dose nicotine exposure while creating a far more invisible form of harm and addiction in populations that otherwise might never have used nicotine products at all.
What I’ve learned as an addiction psychiatrist is that the newest addictions rarely arrive looking dangerous. The hardest substances to recognize are those that no longer require us to step outside to use them. The most unsettling addictions are not the ones that visibly unravel a life. They are the ones that weave themselves so seamlessly into it that the warning signs arrive long after the damage has already taken effect.
