How long does it take for your lungs to heal from vaping? What the evidence shows so far

By Antonio Cappiello · Last reviewed 2026-09-21

There is no vaping-specific healing timeline: the NHS says vaping is too new to know its long-term effects. Among 6,378 young adults, new wheeze or night cough appeared each year in 25 percent of current vapers, 21.6 percent of former vapers and 14.5 percent of never-vapers. For smokers, cough and breathlessness improve within 1 to 9 months.

Do your lungs heal after you quit vaping?

Nobody can promise you a date: the studies do not exist yet. The NHS says vaping “has not been around for long enough to know the risks of long-term use”. A 2019 BMJ review found few studies of lung function after a break from vaping and warns that, because smoking takes decades to cause COPD or lung cancer, the population effects of vaping “may not be apparent until the middle of this century”.

What has been measured is symptoms. In 6,378 US young adults followed 2014 to 2019, new wheeze or night cough appeared each year in 14.5 percent of never-vapers, 21.6 percent of former vapers and 25.0 percent of current vapers. In 2,094 young Californians followed for 4 years, cough and breathlessness tracked current vaping more than last year’s, and people who vaped in both years had the highest odds. So symptoms track current vaping most, though former vapers still had more new symptoms than never-vapers (former against current was not tested), and a 2014 survey of 2,086 teenagers found past users’ odds of chronic bronchitis symptoms about as high as current users’; its authors note the teens with symptoms may be the ones who stopped. Nobody has measured a return to never-vaper lungs.

What does vaping do to your lungs?

The NHS lists coughing, throat irritation and shortness of breath as common side effects; in the California study, current vapers had about twice the odds of wheeze (1.95), chronic cough or phlegm (2.10) and shortness of breath (1.81) of never-vapers, and the odds stayed above 1.4 after adjusting for cigarettes, cannabis and secondhand exposure. In 2,086 high-schoolers surveyed in 2014, the odds of chronic bronchitis symptoms were almost double among vapers.

Lung function studies mostly test the minutes after vaping, with mixed results; one compared 30 never-smoking daily vapers with 30 matched non-users: 4.6 liters blown out in the first second against 5.2, but measured after only an hour without vaping, so possibly temporary airway narrowing rather than lasting change. Australia’s health department lists “respiratory problems and permanent lung damage” among the known risks of vaping, without saying how often it happens to nicotine vapers.

How long does it take for your lungs to heal after quitting vaping?

Smoking rows come from the NHS and WHO quit timelines, vaping rows from the studies above and the 2019 lung injury outbreak. Vape aerosol contains no tar or carbon monoxide, so do not read one as the other.

Time after stopping	What the evidence shows	Evidence from
48 hours	Lungs start clearing out mucus (NHS)	Smoking
72 hours	Breathing feels easier as the bronchial tubes relax (NHS)	Smoking
2 to 12 weeks	Circulation improves and lung function increases (WHO)	Smoking
1 to 9 months	Coughing and shortness of breath decrease (WHO); NHS: coughs, wheezing and breathing problems improve at 3 to 9 months as lung function rises by up to 10 percent	Smoking
12 months later (time since stopping not recorded)	New wheeze or night cough each year: 21.6 percent of former vapers, 25.0 percent of current vapers, 14.5 percent of never-vapers	Vaping, 6,378 young adults
Previous survey, 1 to 2 years earlier (time since stopping not recorded)	Cough and breathlessness tracked current vaping more than last year’s; wheeze tracked both; vaping in both years carried the highest odds	Vaping, 2,094 young people over 4 years
After EVALI (2019 lung injury)	82 percent of 140 patients given corticosteroids improved during treatment; lung tests advised 1 to 2 months after discharge; long-term effects “are not known”	Vaping-related lung injury, 2019
10 years	Risk of death from lung cancer half a continuing smoker’s (NHS); COPD damage, where it exists, “is permanent” (NHS)	Smoking

What was EVALI?

EVALI is the 2019 to 2020 lung injury outbreak: 2,668 people hospitalized in the US by January 14, 2020, 52 deaths by December 10, 2019, median age 24. Nearly all had cough, chest pain or shortness of breath; 77 percent had stomach symptoms and 85 percent fever, chills or weight loss. 82 percent reported THC products, mostly from informal sources, and vitamin E acetate, an additive in those products, is strongly linked to the outbreak; 14 percent reported nicotine only. Many patients’ symptoms resolved; 2.7 percent of those discharged were readmitted. CDC guidance says stopping vaping might speed recovery and going back could bring the injury back.

When should you see a doctor now?

Chest pain, breathlessness at rest and coughing up blood are on no withdrawal list. The NHS says to get urgent help for chest pain, difficulty breathing, coughing up blood, feeling very unwell, or a cough that is very bad or quickly getting worse. Fever with breathing trouble, or stomach pain and vomiting with a cough, was the EVALI pattern: get it checked the same day and say what you vape.

What helps your lungs after you stop vaping?

Every source agrees on stopping; how is up to you. The NHS describes quitting in one step, with a fast-acting nicotine replacement product for cravings, and cutting down gradually: lower the nicotine strength, stretch the time between vapes, make some places vape-free, and treat vaping more as a sign you cut too fast. Australia’s health department recommends a walk or exercise for cravings and mood; no source here says exercise, a supplement, a tea or a “detox” product repairs lungs. The benefits of quitting vaping and the quitting vaping timeline cover the rest.

Cutting down needs a number. Puff Counter’s free one-tap count shows your real daily puff total, when they cluster and the time since the last one. The quit plan, a Premium feature, sets a daily limit from your own average and lowers it step by step to a quit date.

Questions people also ask

What do 2 years of vaping do to your lungs?

No study isolates 2 years. In 2,094 young people followed for 4 years, those who vaped in two consecutive yearly surveys had the highest odds of wheeze, cough with phlegm and shortness of breath, and in 2,086 teenagers chronic bronchitis symptoms rose with days vaped per month (odds 1.66 times never-vapers' at 1 to 2 days a month, 2.52 at 3 or more), though the trend weakened and lost significance once cigarette smoking and secondhand smoke were taken into account.

Can lungs recover from 10 years of vaping?

Nobody knows yet: the NHS says vaping has not been around long enough to know the long-term risks, and a 2019 BMJ review found few studies of lung function after a break from vaping. The smoking data say cough and breathlessness improve within 1 to 9 months of quitting, and in young adults former vapers developed fewer new symptoms than current vapers but more than never-vapers.

Can black lungs turn pink again?

No health agency measures lung color. What is measured after quitting smoking is function: the NHS says coughs and wheeze improve at 3 to 9 months as lung function rises by up to 10 percent, COPD damage, once it has happened, is permanent, and both the NHS and Australia's health department note that vape aerosol contains no tar.

Why do my lungs hurt after quitting vaping?

Chest pain and breathlessness at rest are on no nicotine withdrawal list. The NHS says to get urgent help for chest pain, difficulty breathing, coughing up blood or a cough that is very bad or quickly getting worse; fever with breathing trouble, or stomach pain and vomiting with a cough, was the EVALI pattern, so see a doctor the same day and say what you vape.

Why am I coughing after quitting vaping?

A cough, dry throat and nasal drip are on Australia's health department list of what quitting nicotine feels like. Australia's health department puts these withdrawal feelings at a few days to a few weeks. See a doctor if it lasts more than 3 weeks, and urgently if you cough up blood, have chest pain or find it hard to breathe.
