Short answer
Nicotine withdrawal begins 4 to 24 hours after your last cigarette or vape, peaks around day 3, and most symptoms return to baseline within 3 to 4 weeks.
Knowing the shape of withdrawal in advance makes it far easier to sit through. The worst of it is short, it arrives on a predictable schedule, and almost nobody is told that before they quit.
The timeline
| Time since quitting | What is happening |
|---|---|
| 4–24 hours | Withdrawal begins. Irritability, restlessness, and the first strong cravings. |
| Day 1–2 | Cravings build. Headaches, difficulty concentrating, increased appetite. |
| Day 3 | Usually the peak. Nicotine is effectively out of your system — which is exactly why this day is hardest. |
| Day 4–7 | Headaches and physical restlessness begin to ease. Sleep may still be disrupted. |
| Week 2 | Cravings notably less frequent. Mood and concentration start to normalise. |
| Week 3–4 | Most symptoms at or near baseline. Appetite may stay elevated. |
| Month 2–3 | Occasional cue-triggered cravings. Physical withdrawal is over. |
Symptoms people are not warned about
- Mouth ulcers. Common in the first two weeks and harmless.
- Coughing more, not less. Cilia in your airways start working again and clear built-up debris. It is recovery, not damage.
- Genuine sadness. Low mood is a recognised withdrawal symptom, not a personality change.
- Constipation. Nicotine is a gut stimulant. Digestion takes a few weeks to recalibrate.
- Vivid dreams. Especially in the first week, and especially if you used patches overnight.
Does vaping withdrawal differ from cigarettes?
The dependence is on nicotine either way, so the timeline is broadly the same. Research on vaping suggests most symptoms return to baseline within about 10 days, though some people report several weeks.
One practical difference: vaping is often all-day grazing rather than discrete cigarettes, so some people find their cue-triggered cravings are more diffuse and harder to pin to a specific moment.
