Does nicotine raise blood pressure? What happens to your pressure and pulse

Short answer

The answer to "does nicotine raise blood pressure" is yes, and it happens within minutes: nicotine switches on the sympathetic nervous system, and pressure and pulse climb soon after it reaches your blood. A review of nicotine's cardiovascular effects puts it plainly: "Smoking a cigarette acutely increases blood pressure, an effect mediated by nicotine" (1). The same review notes that heart rate and blood pressure rise whether nicotine comes from tobacco smoke or from another route (1). What is far less settled is whether nicotine on its own, without smoke, leaves you with permanently high blood pressure; the long-term research is mixed and mostly observational.

If you have felt your heart thump after a vape or a pouch, or seen a higher number on a home cuff after a cigarette, you are not imagining it. It is one of the oldest and most consistently measured effects in nicotine research, and noticing it is not overreacting.

Note: this article explains what research and clinical guidelines say and is not medical advice. It cannot tell you what is happening in your body or what your readings mean. A very high reading with chest pain, shortness of breath, numbness, weakness, vision changes or trouble speaking is a reason to call 911, not to read further.

Does nicotine raise blood pressure?

Yes. Nicotine raises blood pressure mainly by activating the sympathetic nervous system, the same "fight or flight" wiring that speeds you up under stress.

The mechanism is well described. Benowitz and Burbank explain that nicotine's effects on the circulation run mainly through the sympathetic nervous system: it releases norepinephrine from nerve endings and increases the release of epinephrine (adrenaline) from the adrenal glands (1). The heart beats faster and harder, and blood vessels narrow. Omvik's review adds that the rise comes from both an increase in the heart's output and an increase in resistance in the blood vessels, that it appears immediately, and that among the thousands of substances in tobacco smoke it is nicotine that drives it (2).

Experiments with e-cigarettes help separate nicotine from everything else. In a crossover study of 33 healthy non-smokers, an e-cigarette with nicotine shifted heart rate variability toward sympathetic dominance, while the same device without nicotine, and a sham session, did not (3). The authors concluded that the acute effect "is attributable to the inhaled nicotine, not to non-nicotine constituents in e-cigarette aerosol" (3).

For the pulse side of the story, our article on how nicotine and vaping affect heart rate and sleep goes into more detail.

How much does nicotine raise blood pressure?

Usually by a few points, sometimes by ten or more, depending on the product, how fast the nicotine arrives and who is using it. There is no single figure, and studies report a wide range.

Benowitz and Burbank put the acute rise from a cigarette at about 5–10 mmHg (1). A large 2023 study tested 395 adults: people who vaped exclusively, people who smoked exclusively, and people who used neither (4). After a 15-minute session with their usual product, systolic pressure in the vaping group rose by an adjusted 5.6 mmHg, against 2.3 mmHg in non-users who went through the same session; diastolic pressure rose 4.2 versus 2.0 mmHg, and heart rate rose 4.8 bpm while it fell slightly in non-users (4). The authors report values similar to those in cigarette users.

Pooled analyses land at different numbers because they combine different devices, nicotine levels and people: about 2 mmHg systolic in a 2019 meta-analysis (5), and around 13 mmHg systolic and 8 mmHg diastolic against non-use in a 2025 one (6).

The last row matters. In Arastoo's study, smoking one cigarette raised pressure significantly more than vaping with nicotine, "despite a similar increase in nicotine" (7). Nicotine drives the response, but burning tobacco appears to add to it.

How long does nicotine raise blood pressure?

After a single use, roughly 15 to 45 minutes in controlled studies. With repeated use through the day, the rises overlap and pressure can stay higher for as long as you keep using.

In a randomized crossover study of 15 smokers, systolic pressure stayed significantly raised for about 45 minutes after vaping a nicotine liquid and for about 15 minutes after smoking a cigarette; heart rate stayed up for about 45 and 30 minutes respectively (8). A nicotine-free liquid produced no significant change during the first hour (8).

The picture changes when use is repeated. When smokers had one cigarette every 15 minutes, the first cigarette produced an immediate, marked rise in pressure and pulse, and each effect lasted long enough that pressure stayed higher throughout the smoking hour; in people smoking through a working day, daytime pressure was persistently higher than on a non-smoking day (9). Benowitz and Burbank describe smoking as raising blood pressure briefly many times a day, and note that blood nicotine levels rise over the first six to eight hours of regular use and then plateau (1).

Night looks different. In 24-hour monitoring, nighttime measurements showed only minor differences between people who used tobacco and people who did not (1000137-X)), and in a one-week quitting experiment, nighttime blood pressure did not differ significantly between smoking and non-smoking weeks (11).

This is why timing matters when you measure. The American Heart Association's home monitoring advice is: "Don't smoke, drink caffeinated beverages or exercise within 30 minutes before taking your blood pressure" (12). Groppelli's group made the mirror-image point about clinics: the raised pressure during smoking "may escape clinic blood pressure measurements performed during non-smoking" (9). Telling your clinician when you last used nicotine before a reading is useful information in either direction.

And a reading is not always just a nicotine reading. If a home measurement is above 180/120 mmHg and you have chest pain, shortness of breath, back pain, numbness, weakness, a change in vision or difficulty speaking, the American Heart Association says to call 911 (13). That is not a spike to wait out.

Does vaping raise blood pressure?

Yes, in the short term, when the liquid contains nicotine. Studies of nicotine-free vaping mostly show little or no change in pressure.

The controlled experiments above agree on this: pressure rose after vaping with nicotine (8, 4), and in Arastoo's study it rose after an e-cigarette with nicotine but not after a nicotine-free one or a sham session (7).

Newer devices can deliver a lot of nicotine. Benowitz and Burbank note that early "cig-alike" devices delivered much less nicotine than cigarettes, while newer high-voltage devices can deliver doses in some cases similar to cigarettes (1). How strongly a vape affects your pressure depends heavily on how much nicotine actually reaches your blood.

Does vaping cause high blood pressure?

Whether vaping leads to lasting high blood pressure is not yet known, and the long-term studies disagree. A US cohort of 17,539 adults found that cigarette smoking was associated with a higher risk of self-reported hypertension (adjusted HR 1.21), while exclusive vaping was not (adjusted HR 1.00) (14). A cohort of 11,623 Hispanic and Latino adults followed for a median of six years found that ever using e-cigarettes was associated with a higher risk of developing hypertension (HR 1.49), although blood pressure change over time did not differ by vaping status (15). The 2025 meta-analysis found no significant difference in resting blood pressure between vapers who had never smoked and non-users (6). All of this is observational, so "associated with" is as far as it goes.

Does a nicotine-free vape raise blood pressure?

In the controlled studies available, not significantly. Nicotine-free liquids produced no significant blood pressure change in the first hour (8), and the nicotine-free e-cigarette did not produce the sympathetic shift seen with nicotine (3). That does not mean nicotine-free aerosol has no other effects; it means the pressure response tracks nicotine.

Cigarettes, vapes, pouches and patches: is there a difference?

Yes. All of them deliver nicotine, but how fast it arrives, how much arrives and whether tobacco is burned change the size of the blood pressure response.

The guiding principle comes from Benowitz and Gourlay: the cardiovascular effects of nicotine "are, in general, more intense when delivered rapidly by cigarette smoking than the slower delivery by transdermal nicotine or nicotine gum" (1600079-X)). They also note that the dose–response curve for nicotine is flat, so using nicotine replacement on top of smoking produces effects much like smoking alone (1600079-X)).

Does Zyn raise blood pressure?

Tobacco-free nicotine pouches, the category Zyn belongs to, have been studied very little, and no study of blood pressure over months or years is available. The clearest data come from a 2024 crossover study of 15 smokers who used pouches of different strengths from several brands, a nicotine-free pouch and a cigarette (17). During use, heart rate rose by about 27 bpm with the cigarette and by about 12 and 25 bpm with the two stronger pouches. The authors report that "effects on systolic and diastolic blood pressure were minor for all study arms," but they also describe a significant rise in peripheral and central systolic pressure with the high-nicotine pouches and the cigarette at the start of use (17). The strongest pouch tested delivered more nicotine into the blood than the cigarette did.

Do nicotine pouches raise blood pressure over time?

Nobody knows yet for tobacco-free pouches. The closest long-term evidence comes from Swedish snus, an older oral tobacco product, which is not the same thing. In 24-hour monitoring of healthy middle-aged men, daytime diastolic pressure was on average 5 mmHg higher in both snus users and smokers aged 45 or older than in non-users (1000137-X)). At the same time, Benowitz and Burbank write that most smokeless tobacco studies do not show more hypertension in users (1). A fair summary: pouches raise pulse in the short term, and their long-term effect on pressure is unknown.

Do nicotine patches raise blood pressure?

Patches deliver nicotine slowly, and the research finds their cardiovascular effects smaller than smoking's. Benowitz and Gourlay concluded that the risks of nicotine replacement are at worst no greater than those of smoking, and small even for smokers with heart disease (1600079-X)). A 2014 network meta-analysis of 63 randomized trials found no clear evidence of harm from nicotine replacement for major adverse cardiovascular events, but did find a higher risk of less serious events (18), such as a fast or irregular heartbeat (1). Whether nicotine replacement fits your situation, and in what form, is a decision your clinician makes with you; this article gives no doses or product choices.

Does nicotine gum raise blood pressure?

Gum, like the patch, delivers nicotine more slowly than a cigarette, and Benowitz and Gourlay group the two together when they describe effects that are in general less intense than smoking (1600079-X)). No large study has looked at gum and long-term blood pressure on its own. If you already have high blood pressure or heart disease, the same review notes that smokers with cardiovascular disease are advised to get a physician's counseling before using nicotine products (1600079-X)); your clinician decides which options apply to you.

Does nicotine cause high blood pressure long term?

The short-term rise is certain; a lasting rise from nicotine alone is not. Long-term studies of smokers give surprisingly mixed results, partly because of how and when blood pressure gets measured.

Benowitz and Burbank describe the puzzle: in most population studies, regular smokers do not have higher blood pressure, and readings are usually taken after a short break from smoking, when the effect has faded; with 24-hour ambulatory monitoring, average pressure is higher while a person is smoking (1). In the Health Survey for England, with 33,860 adults, only older male smokers had higher systolic pressure than non-smokers, and among women, light smokers tended to have lower pressure; the authors concluded that "any independent chronic effect of smoking on BP is small" (19). Yet a US cohort found that smoking was associated with a 21% higher risk of being diagnosed with hypertension (14).

Does nicotine raise blood pressure permanently?

Not after a single use: the acute effect wears off within the hour (8). The concern with daily use is different. Repeated rises through the day (9), higher daytime pressure in tobacco users aged 45 and over (1000137-X)), and an association between smoking and later hypertension (14) all point to a cumulative pattern. Benowitz and Burbank also note that sympathetic nerve activity in smokers stays chronically raised, which they describe as presumably an effect of nicotine (1). Whether nicotine without smoke produces the same long-term picture is what the vaping and pouch studies have not yet settled.

Does nicotine lower blood pressure?

No. Some people read that smokers have lower average blood pressure and conclude the opposite, but researchers point to how and when readings are taken and to other differences between groups, not to a calming effect. Omvik calls it a paradox: smoking acutely increases pressure, yet "a slightly lower blood pressure level has been found among smokers than nonsmokers in larger epidemiological studies" (2). Explanations include readings taken after abstinence (1) and differences in body weight and alcohol intake (19). The direct effect of nicotine itself is to raise pressure (2).

Will quitting nicotine lower blood pressure?

In the short term, usually yes: daytime pressure and pulse come down once the repeated nicotine rises stop. Over months the picture is more complicated, and the long-term heart benefit of quitting smoking is clearer than its effect on the blood pressure number itself.

In a randomized crossover study of 39 healthy male smokers with normal blood pressure, one week without cigarettes lowered 24-hour blood pressure by 3.5/1.9 mmHg and 24-hour heart rate by 7.3 bpm compared with a normal smoking week (11). Heart rate variability was higher, and adrenaline and noradrenaline levels were lower (11). Switching from smoking to vaping has also been linked to lower systolic pressure in pooled studies (5, 6), although that is switching, not stopping nicotine.

Two complications are worth knowing before you judge your own readings:

• Weight. In a meta-analysis of 62 studies, people who quit without treatment gained an average of 4–5 kg by 12 months, most of it in the first three months, with wide variation: about 16% lost weight and 13% gained more than 10 kg (20).

• Blood pressure can drift up anyway. In a four-year study of 8,170 Korean men, those who had quit for three years or more had a higher risk of hypertension than continuing smokers, including those who did not gain weight; the authors say the mechanism "remains unknown" (21). Omvik's review also notes that pressure may rise after quitting, and that a quit program should not delay blood pressure treatment for people whose clinician says they need it (2).

None of this makes smoking the safer option for your heart. The CDC lists a heart rate drop within minutes of quitting, a risk of heart attack that "drops sharply" in one to two years, and an added risk of coronary heart disease that falls by half within three to six years (22). What it means is that blood pressure after quitting is worth checking, not assuming.

When a high reading needs a doctor

Repeated high readings, measured correctly, are worth discussing with a clinician, and a very high reading with symptoms is an emergency. Nicotine can push a reading up for a while, but it does not make a high reading safe to ignore.

The guideline categories. The 2025 AHA/ACC guideline defines normal blood pressure as below 120 systolic and below 80 diastolic; elevated as 120 to 129 systolic with diastolic below 80; stage 1 hypertension as 130 to 139 systolic or 80 to 89 diastolic; and stage 2 as 140 or more systolic or 90 or more diastolic (23). These are population categories for correctly measured readings, which is why the 30-minute no-nicotine rule (12) matters before anyone compares a reading with them.

Very high readings. The American Heart Association says that if a reading is higher than 180/120 mmHg, you should wait at least a minute and measure again (13). If it is still that high and you have chest pain, shortness of breath, back pain, numbness, weakness, a change in vision or difficulty speaking, call 911. If it is still that high without symptoms, contact your health care professional as soon as possible (13).

Stroke signs do not wait for a cuff. The CDC lists sudden numbness or weakness in the face, arm or leg, especially on one side; sudden confusion or trouble speaking; sudden trouble seeing; sudden trouble walking or loss of balance; and a sudden severe headache with no known cause. Its instruction: "call 9-1-1 right away" (24).

A heartbeat that will not settle. The NHLBI lists chest pain, dizziness and fainting among the symptoms of arrhythmia, and advises emergency care for serious symptoms such as chest pain or difficulty breathing (25). A racing or irregular heartbeat that does not settle after nicotine wears off, especially with dizziness, is a reason to call a clinician the same day.

Nicotine and blood pressure: the questions people ask next

Is it safe to vape or use a pouch before a workout?

Nicotine adds its own push to blood pressure and pulse on top of what exercise already does. In a study of 395 adults, people who vaped performed worse than non-users on every exercise measure tested, including exercise capacity and heart rate recovery in the first minute after exercise (4). That is an association in long-term users, not proof that one vape spoils a workout. A practical approach is to notice whether workouts feel different on days with and without nicotine, and, if you have high blood pressure or a heart condition, to ask your clinician whether nicotine before exercise is a concern for you. Chest pain or difficulty breathing during exercise is a reason to stop and seek emergency care (25).

Should I avoid nicotine before a blood pressure check?

Yes, for an accurate reading. The American Heart Association's home monitoring guidance says not to smoke, drink caffeinated beverages or exercise within 30 minutes before measuring, to rest quietly for at least five minutes, and to take two readings one minute apart (12). Nicotine raises blood pressure within minutes, and after a vape the rise lasted about 45 minutes in one study (8), so a reading taken right after use describes the nicotine as much as your baseline. At the doctor's office, tell the person measuring when you last used nicotine, so they can interpret the number rather than be misled by it.

Why is my resting heart rate higher on days I use nicotine?

Because nicotine raises heart rate as well as blood pressure. Benowitz and Burbank report rises of up to 10–15 bpm acutely and about 7 bpm on average across a day of smoking (1). In a one-week quitting experiment, 24-hour heart rate was 7.3 bpm lower without cigarettes than with them (11). If your pulse looks higher than usual on nicotine days, that fits the research, but your own history is the comparison that matters, not a population number. Our guide to what a normal resting heart rate is explains how resting pulse is measured and what else moves it.

Does nicotine affect blood pressure at night and my sleep?

Nicotine's blood pressure effect is mainly a daytime phenomenon. In 24-hour monitoring, nighttime blood pressure differed little between tobacco users and non-users (1000137-X)), and in a one-week quitting study, nighttime pressure did not differ significantly between smoking and non-smoking weeks while 24-hour pressure did (11). Sleep itself is another matter: insomnia is one of the recognized nicotine withdrawal symptoms, and withdrawal symptoms peak in the first week of quitting (26). For more on nicotine, pulse and sleep, see our article on nicotine, vaping, heart rate and sleep.

Is nicotine more dangerous if I already have high blood pressure?

It deserves more caution, and it is a conversation for your clinician. A review of nicotine's cardiovascular safety concludes that the risks of nicotine without tobacco smoke are low compared with smoking but remain a concern in people with cardiovascular disease (1). Omvik's review notes that tobacco smoking may partly cancel the blood pressure lowering effect of beta-blockers (2), which is one reason your prescriber needs to know whether you smoke or use other nicotine products. If you take blood pressure medication, do not change it because of anything you read here; tell the person who prescribed it what kind of nicotine you use and how often.

Will my blood pressure go up when I quit?

For most people, the first week without cigarettes brings daytime blood pressure and pulse down (11). Over the following months, two things can push the other way: weight gain, averaging 4–5 kg at a year (20), and a drift in blood pressure seen in some cohorts even without weight gain (21). Withdrawal symptoms such as anxiety, irritability, restlessness and insomnia peak in the first week and last two to four weeks (26). A practical approach is to keep measuring the same way through the quit and share the readings with your clinician, rather than drawing conclusions from one bad day.

Is this forever, or does it settle?

The acute rise after each use settles within the hour (8), and the daily pattern of repeated rises stops when nicotine stops: one week without cigarettes was enough to lower 24-hour pressure and pulse in a controlled study (11). What does not reset overnight is the longer-term cardiovascular risk from smoking. The CDC describes heart attack risk dropping sharply one to two years after quitting, and coronary heart disease risk approaching that of someone who does not smoke after 15 years (22). For vapes and pouches, the long-term picture is still being studied.

How to bring this up with your doctor

Say it in one sentence first: "I use nicotine, mostly [vapes / pouches / cigarettes], about [how often], and I'd like to know whether it's affecting my blood pressure." That gives the product, the frequency and the question without you needing to guess the answer.

Be specific about the product. Cigarettes, vapes, pouches, gum and patches deliver nicotine at different speeds (1600079-X)), and clinicians cannot assume which one you use. If you use more than one, say so.

Bring readings taken the right way. Measure after 30 minutes without nicotine, caffeine or exercise, after five minutes of quiet rest, and take two readings a minute apart (12). If you also have a few readings taken soon after using nicotine, label them as such. The American Heart Association suggests bringing a monitor with built-in memory to appointments (12).

Mention your medicines. Smoking may blunt the effect of some blood pressure drugs (2), so the full list, including anything over the counter, belongs in the conversation.

Ask questions you can act on:

• "Do my readings put me in a range where you'd want to check further?"

• "Is nicotine a concern with my heart, my medicines or my other conditions?"

• "If I want to quit, what support is available to me, and what should I watch for in my blood pressure while I do?"

The CDC lists the free US quitline, 1-800-QUIT-NOW (1-800-784-8669), among its quitting resources (27). Which quitting method or medicine, if any, suits you is a decision for you and your clinician.

And do not wait for the appointment if a reading stays above 180/120 mmHg with chest pain, shortness of breath, back pain, numbness, weakness, vision changes or difficulty speaking, or you notice sudden stroke signs. Call 911 (13, 24).

How Welltory helps — and what it cannot do

The limits first. Welltory is a general wellness product, not a medical device. It does not diagnose, detect, predict, monitor, prevent, treat or mitigate high blood pressure, hypertension, nicotine dependence or any other condition. It cannot measure blood pressure; for that you need a cuff. It cannot tell you whether nicotine is harming you. What it can do is help you keep a record that is more accurate than memory.

You note the nicotine; the app is already recording heart data. When Welltory flags a stress stretch and asks "What happened?", you can tap a suggested tag, type a few words or just talk: "vape", "pouch", "cigarette", "no nicotine today", "quit day 3", "craving". The app does not know you used nicotine. You do, and you are the one putting it on the record.

If you use a cuff, add the readings. You can enter blood pressure by hand through the plus icon or your Journal, or sync a connected cuff through Apple Health, Health Connect or Samsung Health, and see your readings on a chart beside the rest of your data. Add a note saying whether the reading came before or after nicotine.

Then look at the days side by side. Resting heart rate, HRV, stress minutes, sleep analysis and Battery are recorded the same way on days with and without nicotine. Placed next to your tags, they become a dated diary: what you did, and what was being measured at the time. These heart, stress and sleep measures are your own numbers against your own history, not a population range and not a line marked normal. Stress minutes, sleep analysis and Battery need a supported wearable.

After a few weeks of tagging, My Patterns has something to work with. My Patterns collects the tags you add to stress and rest stretches on the Today screen, so it needs iOS with an Apple Watch or Oura. Patterns appear at around seven tagged events in the current month, with some history from the month before. It shows which tagged situations tend to come alongside stressful stretches, which tags do not happen often but hit your body hard, trends by day of week, heart-rate data, and every time a tag occurred.

That record is what you take to the appointment. The Journal (Premium) keeps your measurements, tags and notes, and from the Welltory web app you can export a CSV (Dashboard → choose a chart → Export). It is a record you made, not a conclusion the app reached. Any pattern in it is an association to discuss with your doctor, not proof that nicotine caused anything.

The red flags belong here too, in the same type size: a blood pressure reading above 180/120 mmHg with chest pain, shortness of breath, back pain, numbness, weakness, vision changes or difficulty speaking, or sudden signs of stroke, means calling 911, not adding a tag (13, 24). A racing or irregular heartbeat that does not settle, especially with dizziness, means calling a clinician the same day (25).

Where to find other people in the same situation. If you are also living with an energy-limiting condition, Welltory runs a paid, moderated community called Energy Lab for women aged 18 to 65 living with ME/CFS, long COVID, fibromyalgia, POTS, MCAS and similar. It runs alongside the app: you keep collecting your own data, and the Lab is where people learn to read it together, with a medical board answering the science. It is education and peer support, not medical care, it does not replace your clinician, and there is a 14-day money-back guarantee on a first purchase.
