How to Quit Vaping: What Actually Happens

Why quitting vaping is not the same as quitting cigarettes

A cigarette gives you a fixed dose and then it is gone. You smoke it, you stub it out, the pack goes back in the drawer, and there is a smell on your hands that tells you what you just did. A vape does none of that. It sits in your pocket, charged, and delivers nicotine in a way that is easy to top up without noticing. Many people who vape take a puff every few minutes across a waking day rather than twelve discrete hits. That changes what stopping feels like.

The dose is also often higher than people assume. A 20 mg/mL nicotine salt e-liquid is 20 milligrams of nicotine per millilitre. A single millilitre of that liquid contains roughly the nicotine of ten cigarettes, depending on how the device is set and how deeply you draw. The UK’s Medicines and Healthcare products Regulatory Agency caps nicotine strength in e-liquids at 20 mg/mL, which is the figure most UK vapers are working with. Some people go through two millilitres a day. Some go through ten. The number on the bottle does not tell you your daily intake; the number of millilitres you get through does.

This is why “just use willpower” lands differently for vaping. There is no ash, no smell, no social cue to mark the moment you stop. The device is still in your pocket at 11pm on day three, and it is still there on day thirty. The quit is not a single decision you make once. It is a decision you make every time you reach for something that is not there.

What vaping withdrawal actually looks like

Nicotine withdrawal is a set of physical and psychological symptoms that begin within a few hours of your last dose and peak in the first three to five days. The symptoms are the same whether the nicotine came from a cigarette, a vape, or a patch. What differs is the shape of the intake curve.

With cigarettes, most people have a fairly regular pattern: morning, breaks, after meals, evening. The brain learns to expect nicotine at those points. With a vape, the intake is often continuous. That means the drop when you stop can feel less like a series of cravings and more like a low-grade fog that does not lift. People describe it as flat, irritable, and hard to name.

The common symptoms, as listed by the NHS and the US Centers for Disease Control and Prevention, include:

• irritability, restlessness, and a short temper
• difficulty concentrating
• low mood or a sense of flatness
• increased appetite, particularly for sweet things
• disturbed sleep, including waking in the night
• cravings that come in waves and last a few minutes each

The timeline is reasonably consistent. The first three days are the sharpest. Symptoms ease noticeably over two to four weeks, though some people report low mood and appetite changes for longer. Sleep usually settles within a month. Cravings can still appear months later, often triggered by situations rather than by nicotine itself, but they are shorter and less frequent.

Day three is often the worst day. That is not a prediction about you; it is the point at which nicotine has largely cleared and the brain is adjusting. It is also the point at which most people who quit and then return to vaping do so. Knowing that the peak is short is more useful than being told to stay strong.

Does tapering the milligrams work?

Tapering means reducing the nicotine concentration in your e-liquid over time, or reducing the number of puffs, or both. It is a common approach and it is not unreasonable. The evidence for it is mixed.

A Cochrane review of nicotine replacement therapy (NRT) found that using NRT before quitting, sometimes called preloading, may help some people, but the effect is modest. The same review found that combining a patch with a fast-acting form, such as gum or lozenge, works better than a single form. That finding is about NRT, not about tapering vape liquid, and the two are not the same thing.

What tapering does well is reduce the size of the step. What it does badly is stretch out the withdrawal. If you drop from 20 mg/mL to 10 mg/mL and then to 5 mg/mL over several weeks, you may spend that time in a low-level withdrawal rather than getting it over with. Some people find that easier. Some find it harder, because the discomfort never quite ends and the device stays in daily use.

There is no trial that shows tapering e-liquid is more effective than stopping outright. There is also no trial that shows it is worse. If you have tried stopping and gone back to it, tapering is a reasonable thing to try, but it is not a guaranteed route and it is not a cure.

Should you use nicotine replacement to come off a vape?

This is the part that surprises people. NRT is licensed and sold for smoking cessation, not for vaping cessation. The patches, gum, lozenges, and sprays are designed around the nicotine delivery of cigarettes. A vape can deliver more nicotine, more continuously, than a cigarette. That means a standard 21 mg patch may not cover what you were getting from a high-strength vape, and it may cover it in a different pattern.

The evidence base here is thin. The Cochrane review on NRT is about smoking, not vaping. There is no large trial that says “use a patch to quit vaping and here is how well it works.” What there is, is clinical experience and a reasonable physiological argument: if you are dependent on nicotine, replacing some of it while you break the behavioural habit can reduce the severity of withdrawal. Whether that works for you is not something a page can tell you.

What the trials do show is that NRT roughly doubles the odds of quitting smoking compared to placebo or no support, according to the Cochrane review. That is a real effect and it is worth knowing. It is not a guarantee, and it does not automatically transfer to vaping.

If you are considering NRT for vaping, the decision about which product, what dose, and how long to use it is between you and a pharmacist or your doctor. This page cannot make that decision for you and will not try.

What about prescription medication?

Varenicline is a prescription medicine licensed for smoking cessation. It works by reducing cravings and the reward from nicotine. The trials behind it are for smoking, not vaping, and the effect sizes are larger than for NRT in most of those trials. It is not a cure and it does not work for everyone. It also has side effects, and in some people those side effects are significant.

Whether varenicline is appropriate for quitting vaping is a clinical judgement. It is not licensed for that use in the UK. Any decision to take it, or to stop taking it, belongs to you and your doctor. This page will not tell you to ask for it, start it, or switch to it.

Hypnosis and other approaches

Hypnosis is sometimes offered as a way to stop vaping. The evidence for it is not strong. A Cochrane review of hypnotherapy for smoking cessation found no clear evidence that hypnotherapy performs better than other interventions, and the studies it looked at were small and of low quality. That is the finding, stated plainly. It does not mean hypnosis cannot help some people. It means the trial evidence does not show it is better than anything else.

The same caution applies to acupuncture, laser therapy, and most of the other things sold as quit aids. Where there is good evidence, it is mostly for NRT, varenicline, and behavioural support. Where there is not, the honest answer is that we do not know.

Behavioural support, on its own, has reasonable evidence behind it. That can mean a stop smoking service, a counsellor, a group, or a structured programme. The NHS stop smoking services combine behavioural support with medication and have better outcomes than going it alone, according to NHS data. If you are quitting vaping, the same principle applies: support helps, and it does not have to be medical.

A table of what the evidence actually supports

What to do on day three at 11pm

Nothing here is a cure, and nothing here is guaranteed. What is true is that the peak of withdrawal is short, that the symptoms are known and named, and that there are options with evidence behind them and options without. The decision about which to use is yours, and where prescription medicine is concerned, yours and your doctor’s.

If you are on day three and it is 11pm and you are irritable, the useful facts are these: the acute phase is measured in days, not months; the cravings come in waves of a few minutes; and the fact that you have failed before does not change any of that. It also does not mean you will fail again. It means you are someone who has stopped before, which is information, not a verdict.
