Nicotine withdrawal timeline: symptoms, the worst days and how long it lasts

When nicotine withdrawal starts, when it peaks, how long it lasts and which symptoms are real, for cigarettes, vapes and pouches. Sourced from the NHS.

Nicotine withdrawal is what your body goes through when it stops getting the nicotine it has become used to. It can be uncomfortable, but it is temporary, and knowing what to expect makes it easier to get through. Here is the timeline, the symptoms, and what helps.

Nicotine withdrawal timeline

The NHS and two reviews of the research give the same shape:

• Within a few hours: the NHS says withdrawal can start within a few hours of your last cigarette. A 2015 review puts it at 4 to 24 hours after stopping any product that contains nicotine.
• Days 1 to 3, the peak: the same review says symptoms peak on about the third day. The NHS says they are usually strongest in the first week, especially in the first 3 days.
• The first week: a 2007 review of 120 studies found the main symptoms peak within the first week.
• Weeks 2 to 4, easing: that review found they last 2 to 4 weeks. The NHS says that on average symptoms last 3 to 4 weeks.
• Longer for some people: the NHS says some people feel them for longer, sometimes a few months.

The NHS also says that once you reach 28 days smoke-free, you are 5 times more likely to stay quit for good. The hardest part of withdrawal and that milestone arrive at about the same time.

Symptoms of nicotine withdrawal

The NHS lists the common symptoms:

• strong urges or cravings
• trouble concentrating
• feeling restless
• trouble sleeping
• being easily upset, irritable, frustrated or angry
• feeling anxious, tense or low in mood

The 2007 review found that anger, anxiety, depression, difficulty concentrating, impatience, insomnia and restlessness are true withdrawal symptoms. It found that constipation, cough, dizziness, more dreaming and mouth ulcers may also be effects of stopping. NSW Health adds feeling more hungry than usual.

You might get several of these or hardly any. They can be mild for some people and harder for others.

Is feeling tired a withdrawal symptom?

Not according to the research. The 2007 review found that drowsiness and fatigue are not true effects of stopping. Trouble sleeping is, so if you are tired after quitting, poor sleep is the more likely reason, and it usually settles as withdrawal eases.

Vapes, nicotine pouches and snus

Withdrawal comes from the nicotine, not from the smoke, so you can get it when you stop any of them. The 2015 review describes the same timeline after stopping any product that contains nicotine, and says that how you took nicotine largely decides how strong the symptoms are.

For vaping, NSW Health says the physical withdrawal symptoms usually get better during the first 1 to 2 weeks, but the craving to vape can last longer while your brain adapts. For nicotine pouches and snus there is no separate timeline in these sources, and the NHS says there is not yet enough independent evidence on pouches.

How to get through it

The NHS suggests:

• Stop smoking products: nicotine replacement like patches or gum, nicotine-free medicines, or a vape. Combining a nicotine-free medicine with patches or gum makes you much more likely to quit for good. A pharmacist or your local stop smoking service can help you choose.
• Move: a quick burst of activity when a craving hits.
• Keep your mouth busy: carrots, celery sticks or sugar-free gum.
• Breathe: a slow breath in through your nose, then gently out through your mouth.
• Avoid your triggers for the first 28 days, like a coffee with people who smoke.
• Write your reasons down and keep them where you can see them.

Most of all, remember that cravings and bad feelings go away. NSW Health calls withdrawal symptoms a sign your body is recovering. Our app Nicotine Counter counts the time you have won and shows the health milestones as you reach them.

Will quitting make my anxiety worse?

It can feel that way in the first weeks, because feeling anxious, tense or low is part of withdrawal. But the NHS says smoking actually increases anxiety and tension, and that after people stop, anxiety, depression and stress levels are lower and positive mood improves.

When to talk to a doctor

Talk to your GP or psychiatrist before you stop if you take antipsychotic medicines or antidepressants. The NHS says the dose may need to be monitored and could be reduced.

See a GP if you are pregnant or have a health condition, to find the best way for you to stop, or if low mood is not lifting as the weeks go on.
