Body Recovery Timeline
Enter your quit date to see exactly what’s healing in your body right now, backed by research from the American Heart Association, CDC, National Cancer Institute, and American Lung Association.
When did you quit?
How we built this timeline
Every milestone is sourced from peer-reviewed medical research or authoritative health bodies. We compiled recovery data from the American Heart Association’s benefits-of-quitting timeline, the National Cancer Institute’s withdrawal fact sheet, American Lung Association vaping resources, and Truth Initiative cessation research.
The recovery mechanisms — nicotine clearance, carbon monoxide normalization, vascular healing, cilia regrowth — are the same across smoking and vaping, which is why the timelines used by major health authorities apply to all forms of nicotine cessation.

FAQ
How long does nicotine stay in your system after vaping?
Nicotine itself is metabolized within about 72 hours of your last hit. Cotinine, its primary metabolite that's used in nicotine tests, can stay in your system for up to 10 days. The acute physical withdrawal driven by nicotine clearance peaks around day 3.
When do withdrawal symptoms peak?
Most people experience peak withdrawal symptoms — irritability, anxiety, difficulty concentrating, headaches, restlessness — at 72 hours after quitting. Symptoms then gradually ease over the following 3 to 4 weeks, with most acute physical symptoms resolved by the end of week one.
How long until my lungs fully recover from vaping?
Lung recovery is gradual. Cilia regrow within about 1 month. Lung function can improve by up to 30% within 3 months. By 9 months, most respiratory recovery is complete, and lung cancer risk drops significantly within 10 years of quitting.
Is the recovery timeline the same for vaping as for smoking cigarettes?
Most milestones map closely between vaping and smoking because the recovery is driven by the same mechanisms — nicotine clearance, carbon-monoxide normalization, and vascular healing. The major timeline data comes from smoking cessation research, which the AHA, CDC, and other authorities apply to nicotine cessation broadly.
What if I started vaping again — does the timeline reset?
If you relapse briefly and quit again, you don't lose all your progress — long-term cardiovascular and pulmonary improvements persist. But continuing nicotine use re-engages cravings and resets short-term clocks like the 72-hour nicotine clearance and the 1-week withdrawal cycle. The longer you stay quit, the less a single slip costs.
