Quick answer

If you’ve used nicotine regularly, withdrawal symptoms usually begin 4 to 24 hours after your last cigarette, vape or pouch, peak on day 2 or 3, and then get a little better every day after day 3, fading over 3 to 4 weeks (Cleveland Clinic). Smokefree.gov says the worst symptoms usually last less than two weeks. A research review found the core symptoms (anger, anxiety, low mood, poor concentration, impatience, insomnia and restlessness) peak within the first week and last 2 to 4 weeks.

The first week is when you’re most at risk of slipping back (Cleveland Clinic, Smokefree.gov). Nicotine withdrawal is uncomfortable but not harmful to your health. Everyone is different, and research doesn’t track symptoms precisely day by day, so the day ranges below are a guide, not a rule. For the full timeline, see our nicotine withdrawal timeline.

Nicotine withdrawal by day at a glance

When did you last use or take it?

This places the typical ranges from this article's sources on your date. It is not a prediction or a diagnosis, and being past a phase does not mean symptoms or risks are over.

A rough guide from published sources, not medical advice. Everyone is different.

Phase	When	What you may feel	Severity	Red flags
Day 1	Symptoms begin 4 to 24 hours after your last nicotine	First cravings; Restlessness, irritability; Pulse already settling; carbon monoxide halved by 8 hours (smokers)	Mild	—
Days 2 to 3 (peak)	Symptoms are usually most intense on day 2 or 3	Strong cravings; Irritability, anger, anxiety; Trouble concentrating and sleeping; Increased appetite	Moderate	Low mood that’s severe or thoughts of self-harm: call or text 988
Days 4 to 7	Symptoms get a little better each day after day 3; the first week carries the highest risk of slipping	Cravings that come in waves, often triggered by situations; Foggy thinking; Sleep still unsettled for some	Mild	—
Days 8 to 10	For most, the worst is over within about 2 weeks	Fewer, weaker cravings; Mood and concentration improving; Hunger may continue	Mild	—
After day 10	Remaining symptoms usually fade over 2 to 4 weeks	Occasional cravings; Most symptoms gone by 3 to 4 weeks	Mild	Depression that lingers: talk to a doctor

Days 2 to 3 (peak): Symptoms are usually most intense on day 2 or 3

Strong cravings
Irritability, anger, anxiety
Trouble concentrating and sleeping
Increased appetite

Days 4 to 7: Symptoms get a little better each day after day 3; the first week carries the highest risk of slipping

Cravings that come in waves, often triggered by situations

Day by day: days 1 to 10

Day	What’s typical	What’s happening in your body (if you smoked)
Day 1	Withdrawal begins 4 to 24 hours after your last dose; first cravings	After 20 minutes your pulse starts to return to normal; after 8 hours carbon monoxide in your blood has halved and oxygen is recovering (NHS)
Day 2	Symptoms climbing toward their peak: cravings, irritability, restlessness	After 48 hours carbon monoxide is at non-smoker levels, lungs are clearing mucus, and taste and smell are improving (NHS)
Day 3	Usually the peak day, or close to it	After 72 hours breathing may feel easier as your airways relax, and energy increases (NHS)
Days 4 to 5	A little better each day, though cravings still come in waves	Not separately described in our sources
Days 6 to 7	End of the highest-risk week for slipping back	Not separately described in our sources
Days 8 to 10	For many people the worst is over or ending; Smokefree.gov says the worst usually lasts less than two weeks	Circulation improves over 2 to 12 weeks (NHS)

Notes: vaping and nicotine pouches don’t produce carbon monoxide, so the NHS body-recovery milestones in the right-hand column apply to smoking. The withdrawal timing in the middle column comes from sources about nicotine in general. Day-specific detail for vapes and pouches is not well studied.

What makes it more or less likely

How long, how often and how much. Cleveland Clinic says severity depends on how long you’ve used nicotine, how often, and how much each time.
Your age, genetics and overall health also play a part (Cleveland Clinic).
Triggers. People, places and situations linked to smoking can set off cravings (Smokefree.gov).
Quit medicines. Nicotine replacement therapy and other quit medicines can reduce withdrawal symptoms (Smokefree.gov, Cleveland Clinic).
Past anxiety or depression. Smokefree.gov says some people feel more anxious or low after quitting, especially if they’ve had those symptoms before.

When to see a doctor or get help now

Talk to a health care provider before you quit if you’d like a plan for withdrawal, including medicines (Cleveland Clinic).
Get help if low mood, anxiety or depression after quitting is severe or doesn’t lift; Smokefree.gov advises watching for this, especially if you’ve had it before.
Call or text 988 if you have thoughts of suicide or self-harm.

Tapering

Many people quit on a set date with help from nicotine replacement therapy (patches, gum, lozenges) or prescription quit medicines, which Smokefree.gov and Cleveland Clinic say can ease withdrawal. A health care provider or pharmacist can help you choose. See our guides to stepping down from the nicotine patch and nicotine gum and lozenges. We don’t publish dose-by-dose schedules.

Tips for getting through it

Plan for days 2 and 3: they’re usually the hardest, so keep them as low-stress as you can
Avoid your triggers for a while after quitting (Smokefree.gov)
Go to bed and get up at the same time every day, and skip caffeine for several hours before bed (Smokefree.gov, Cleveland Clinic)
Keep crunchy, healthy snacks handy for hunger and to keep your hands and mouth busy (Smokefree.gov)
Fill your days with routines and lean on people close to you (Cleveland Clinic)
Aim for 28 days: the NHS says once you reach 28 days smoke-free, you’re much more likely to quit for good

Frequently asked questions

What day is nicotine withdrawal the worst?

Usually day 2 or 3, according to Cleveland Clinic. Symptoms get a little better each day after that.

How long does nicotine withdrawal last?

The worst usually lasts less than two weeks (Smokefree.gov). Most symptoms fade over 2 to 4 weeks, though cravings can pop up later.

Is the first week the hardest?

It’s the riskiest: Cleveland Clinic and Smokefree.gov both say the first week is when you’re most likely to slip back.

Why do I feel sick after quitting?

Headaches, nausea, dizziness, cough and sore throat are less common withdrawal symptoms. Cleveland Clinic says they come from the lack of nicotine, not from catching a bug.

Is vape or pouch withdrawal the same day by day?

The nicotine withdrawal pattern is similar because it’s the same drug, but day-specific data for vapes and pouches is limited. See our vape and Zyn pages.
