How long does nicotine withdrawal last?
The short answer: on average, nicotine withdrawal lasts about three to four weeks. Symptoms usually start within a few hours of your last cigarette or vape, are strongest in the first week — especially the first three days — and then fade as your body adjusts. Individual cravings last only about 15 minutes each.12
Because "withdrawal" is really a cluster of separate symptoms, they do not all end at once. Here is roughly how long each one tends to stick around.

How long each symptom typically lasts
| Symptom | Typical duration | Notes |
|---|---|---|
| Individual cravings | ~15 minutes each | Each urge peaks and passes quickly; frequency drops over the first few weeks.2 |
| Peak intensity | Days 2–3 | The hardest window, once nicotine has fully cleared.1 |
| Irritability & anxiety | About 2–4 weeks | Ease as your body adjusts to being nicotine-free.1 |
| Trouble concentrating | A week or two | Usually one of the first symptoms to lift.1 |
| Disturbed sleep | Around the first week | Tends to settle as the acute phase passes.1 |
| Increased appetite | Several weeks or more | Can outlast the other symptoms; hunger often replaces the habit.1 |
| Overall withdrawal | 3–4 weeks on average | A minority feel milder symptoms for a few months.1 |
Why the first three days are the hardest
Withdrawal symptoms are usually strongest in the first three days and across the first week, because that is when nicotine has left your system and your brain is recalibrating to work without it.1 Cravings then improve noticeably after the first two to three weeks — which is why the one-month mark feels so different from day one.1

What makes withdrawal shorter or milder
- Using the 15-minute rule — delay and distract until each craving passes, rather than fighting it.2
- Nicotine-replacement therapy (patches, gum, lozenges) to smooth out the physical drop.1
- Stop-smoking support and medicines, which the CDC notes improve your chances of quitting for good.3
- Avoiding or planning around triggers — coffee, alcohol, stress and old routines that fire cravings.1
Common questions
How long until cravings stop completely?
Physical cravings ease a lot after the first two to three weeks, and most withdrawal is over by three to four weeks. Occasional situational cravings can still surface for months, but they are brief and get easier to ignore.1
Is withdrawal shorter if I taper instead of quitting cold turkey?
Some people find tapering nicotine, or using replacement therapy, makes the physical drop gentler. The overall adjustment still takes a few weeks, but day-to-day it can feel more manageable.1
Why do I feel hungrier for so long?
Increased appetite is one of the withdrawal symptoms that can outlast the others. Nicotine suppresses appetite, so eating more when you quit is expected; planning healthy snacks helps.1
