    Nicotine replacement therapy for vaping is one of the first things people ask about, and it deserves a straight answer. NRT has been studied for decades, but nearly all of that research is in people who smoke cigarettes.1 The trials of NRT for quitting vaping are few, small and short. Here is what is solid, what isn't, how the main NRT types differ, and what to ask your pharmacist before you buy anything.

    What NRT is, and what it isn't#

    NHS Better Health describes NRTs as products that give your body lower amounts of nicotine, but without the dangerous chemicals in cigarettes.2 The aim is to ease cravings and withdrawal while you cut back on the nicotine you get from your vape.

    Two things to keep in mind. The products were built and tested for people who smoke. And the RACGP, which writes the main clinical guidance in Australia, puts behavioural support first and says that when necessary you can use "a registered pharmacotherapy licenced for smoking cessation."3 That is a sensible order for most people to think in, whatever they are quitting.

    What the smoking trials show#

    The strongest NRT evidence comes from trials in people who smoke. Cochrane's 2018 review compared NRT with placebo or no treatment. It identified 136 studies, and 133 of them, with 64,640 participants, contributed to the main comparison. The authors judged the evidence to be of high quality. Any form of NRT gave a risk ratio of 1.55 for abstinence compared with control (95% CI 1.49 to 1.61).1

    Read the participant part before you apply it to yourself. The review says most participants were adults, and that people in the studies typically smoked at least 15 cigarettes a day when they started.1 That is a different situation from many people who vape, and the review does not test vaping at all.

    The 2023 Cochrane update broke NRT down by type. Combination NRT, a fast-acting form plus a patch, gave higher long-term quit rates than a single form (risk ratio 1.27). Fast-acting forms such as gum or lozenges gave similar quit rates to patches.4 In plain terms, combining products beat using one on its own in those trials.

    Nicotine replacement therapy for vaping: what the trials show#

    Here the picture gets thin. The RACGP guidance says: "Currently there is limited research on interventions specifically targeting vaping cessation."3 A 2026 narrative review of vaping cessation trials found three NRT trials, with 567 participants between them. It concluded that the evidence for NRT "remains inconclusive because of the small number of available studies and relatively short follow-up durations."5

    The largest NRT trial we found enrolled 508 young adults aged 18 to 24. It compared coaching calls alone with calls plus mailed NRT, and with calls plus text messages, and with all of them together. Seven-day abstinence at three months, counting missing data as vaping, was 41% for calls only and 48% for calls plus NRT. The authors wrote that "Mailed NRT and mHealth did not significantly improve quit rates, in the context of an active control of a 2-call coaching program."6 So almost half of each group had stopped at three months, and adding NRT made no significant difference on top of the coaching calls.

    The clearest result so far came from a prescription medicine, not NRT. Evins and colleagues randomized 261 people, with an average age of 21.4, to varenicline or placebo, both alongside counseling. Continuous abstinence in weeks 9 to 12 was 51% with varenicline and 14% with placebo.7 It is one trial, its participants were mostly young, and it does not settle the question for adults who vape. Your doctor can talk you through it.

    The NRT types, side by side#

    The table uses NHS guidance for how each product works and how fast it acts.28 It leaves out doses on purpose. The dose is printed on each pack and differs by product, so read the label and ask your pharmacist.

    TypeHow it delivers nicotineHow fastHow it is usedCommon side effectsOften used for
    PatchA steady release through the skinSlow-actingA 24-hour patch worn all the time, or a 16-hour patch worn while awakeSkin rashes and irritation, plus headache, nausea and dizzinessA steady background level; a 24-hour patch if cravings hit when you wake up
    GumChewed, then parked inside the cheek; absorbed through the lining of the mouth and throatFast, in short burstsChewed the special way described on the pack, not like normal gumMouth and throat irritation and dryness; swallowed saliva can bring on nausea, indigestion and hiccupsSudden cravings
    LozengeDissolves in the mouth and is absorbed through the lining of the mouth and throatFast, in short burstsLet it dissolve, following the packThe same mouth and throat effects as gumSudden cravings
    InhalatorYou insert a cartridge and inhale nicotine vapour through the mouthpieceFaster than gum and lozengesFollows the hand-to-mouth action of smokingMouth and throat irritation and drynessPeople who miss the physical action of smoking
    Mouth spraySprayed directly into the mouth; absorbed through the lining of the mouth and throatVery fast-actingSprayed into the mouth, as the pack describesHeadache, nausea and dizzinessQuick relief from cravings

    The NHS says that combining a slow-acting product with a fast-acting one can work best, because the patch covers the background and the faster product handles sudden cravings.2

    Questions to ask your pharmacist

    • Are my cravings steady through the day, sudden, or both? Which products match that?
    • Would a patch with a faster product make more sense than one product on its own?
    • I still vape. How should I use the NRT alongside the vape, and what is my plan for stopping the vape?
    • Do any of my health conditions, medicines or pregnancy change which product is right for me?
    • For Australia: which of these are on the PBS, and what would I pay for each?
    • How long should I plan to use it, and how will I step down?

    Check before you start#

    The cautions differ by product and by person. The Oxford NHS formulary lists caution for "Unstable cardiac disease, diabetes, hyperthyroidism, severe renal or hepatic impairment and peptic ulcer."9 It also says that "NRT patches should not be placed on broken skin or be used in patients with skin disorders," and that "Gastritis, oesophagitis, and peptic ulcers can be aggravated by swallowed nicotine" from sprays, lozenges and inhalators. If you are pregnant, the same guidance says that "24hr patches are also not recommended for use in pregnancy."9 Talk to your doctor or pharmacist before you start, especially if any of these apply to you.

    In Australia: where to get NRT, and what else exists#

    NRT is available from pharmacies and some supermarkets without a prescription, according to health.gov.au. Some NRTs are available at a reduced price through the Pharmaceutical Benefits Scheme (PBS).10 The PBS rules are restrictive and change over time, so check the current listing with your pharmacist. The rules for vapes themselves, and where to get them, are in how to quit vaping in Australia.

    Prescription medicines are a separate question. The same health.gov.au page says "There are other prescription medicines available through the PBS that can reduce withdrawal symptoms, including bupropion and varenicline."10 Cytisine is not an option here. According to RACGP guidance, "Cytisine is not currently approved by the TGA or available in Australia."11 Your doctor can talk you through which of these fits your situation.

    Where to go next#

    A product is only one part of a quit. The how to quit vaping guide covers the whole plan. If you want the minute-by-minute help for a craving that a patch or gum doesn't cover, read vape cravings: what helps in the next 5 minutes. If you're cutting the nicotine strength in the vape itself, how to lower your vape nicotine strength step by step walks through that. And if sleep gets worse once you stop, can't sleep after quitting vaping covers it.

    Whatever your pharmacist recommends, ExHale runs the day-to-day side of your quit. A short quiz builds your personal quit plan: one calibration week, then weekly nicotine step-downs that adapt to what you actually log. One-tap puff and craving logging puts your trends on the Stats and Health screens, so when your pharmacist asks whether your cravings are steady or sudden, you answer from your own log. For the sudden ones, craving SOS has box breathing, 4-7-8 breathing and quick minigames.

    Questions about nicotine replacement for vaping#

    Does nicotine replacement therapy help people quit vaping?

    The evidence for vaping is thin. NRT has strong trial evidence for quitting cigarettes, but the vaping trials are few, small or short. In the largest one we found, 508 young adults were given mailed NRT with coaching, and adding the NRT did not significantly improve quit rates over coaching alone. Talk to your doctor or pharmacist about whether NRT fits you.

    Which type of nicotine replacement is best for vaping?

    Trials for smoking have not shown one type to be clearly better than the rest. A combination of a slow-acting patch with a fast-acting product such as gum or a lozenge beat a single product in the Cochrane 2023 review. Fast-acting forms gave similar quit rates to patches. Many people pick based on whether their cravings are steady or sudden, and on what they can use comfortably.

    Can I get nicotine patches or gum in Australia without a prescription?

    Yes, for most NRT. Health.gov.au says NRT is available from pharmacies and some supermarkets without a prescription. Some NRT products are available at a reduced price through the Pharmaceutical Benefits Scheme, and the rules for that subsidy are restrictive, so ask your pharmacist what applies to you.

    Is nicotine replacement safe if I have a heart condition or diabetes?

    It needs care, so ask before you start. The Oxford NHS formulary lists unstable heart disease, diabetes, an overactive thyroid, serious kidney or liver problems and peptic ulcer as conditions needing caution. Your doctor or pharmacist can check your medicines and health history and tell you which product, if any, suits you.

    How long should I use nicotine replacement?

    The NHS says NRT is recommended for about 12 weeks, or for as long as it's needed to stop you from going back to your old habit, and that you can reduce it gradually when you feel ready. Those figures come from smoking research, so ask your pharmacist or doctor for a plan that fits your vaping.

    Can I use nicotine patches and keep vaping?

    Some people try this, but the evidence on using NRT alongside a vape is limited. Guidance for vapers says the aim is to become nicotine free, so tell your pharmacist you still vape. Ask them how your vape and the NRT fit together, and what your plan is for stopping the vape.
