12 Things That Happen to Your Body When You Stop Vaping

Updated: May 04, 2024

Evidence is stacking up that vaping, once thought to be less harmful than smoking cigarettes, causes lung damage—and can be deadly. It's also addictive, making it hard for anyone who has started to now stop. Just know that the minute you kick the habit, your body will feel the difference, and the benefits start almost immediately.

What is vaping?

When e-cigarettes first hit the market in late 2000, they were believed to be a safer alternative to tobacco cigarettes, but now there is evidence to the contrary. As of 2020, the Centers for Disease Control and Prevention (CDC) counted close to 3,000 cases of the vaping related lung disease known as EVALI (e-cigarette, or vaping, product use-associated lung injury). In statistics gathered by 29 states, the agency has recorded 68 deaths. And then there’s the potential for the habit to aggravate the symptoms of COVID-19, potentially leading to severe cases and increasing the risk of death from COVID.

Vaping is deadly. It’s also addictive. Vaping with a JUUL can be as dangerous as smoking a pack of cigarettes a day. When you vape, you inhale liquid (or e-juice) from a cartridge attached to the vaping device. In addition to nicotine, that liquid can contain dozens of other chemical ingredients and flavorings.

Kids and teenagers have been especially attracted to vaping, thanks in part to attractive flavors like bubble gum, mango, and mint. In November of 2023, the CDC reported that among high school students in the US, overall tobacco use declined during 2022-2023 (16.5% to 12.6%), primarily because of a drop in e-cigarette use.

That may be in part be because in June 2022, the FDA issued marketing denial orders (MDOs) to JUUL Labs Inc., forcing the company to stop selling and distributing its JUUL device and four types of its “JUULpods.” The move was part of a largescale effort by the FDA to put the vaping industry under a microscope, requiring companies to prove that their e-cigarette products benefit the public health by helping people cut back on or quit smoking. Though the agency later decided to temporarily suspend the order to conduct more research, there is still a federal push to regulate vaping and encourage the public to stop using e-cigarettes.

Quitting vaping can be difficult though, just like trying to stop smoking. And while quitting can be hard on the body, you’ll mostly start to benefit as soon as you make the decision to kick the habit. Read on to learn exactly what happens in your body the minute you stop vaping.

20 minutes later: Cardiovascular improvements

In as little as 20 minutes, “your heart rate returns to normal, your blood pressure drops, and your circulation starts to normalize,” says Nikola Djordjevic, MD, project manager of Med Alert Help.

Your breathing may improve, too: The two key ingredients in an e-cigarette—propylene glycol and vegetable glycerin—produce chemicals when heated that are detrimental to your respiratory tract, according to research published in 2018 in the International Journal of Environmental Research and Public Health. “When you quit vaping, you should find that your breathing becomes less labored and your airflow is clearer,” says Caleb Backe, a certified health and wellness expert for Maple Holistics.

A few hours later: Nicotine withdrawals

Nicotine is addictive, and you may experience some minor and temporary symptoms. “Acute nicotine withdrawal symptoms can be psychological and physical,” says Dr. Djordjevic. The psychological symptoms can include cravings for nicotine, mood swings, trouble concentrating, irritability, and anxiety, he says. Physical symptoms include “headaches, sweating, tremors, insomnia, increased appetite, abdominal cramps, and constipation,” Dr. Djordjevic says.

These are the first effects you’re likely to feel, often within four to 24 hours after quitting. These effects will peak around day three, Dr. Djordjevic says, “and gradually decrease during the following three to four weeks. So it will take around a month to break the habit.” If you think smoking e-cigarettes is healthy, these silent ways vaping impact your body may surprise you.

One day later: Heart attack risk falls

According to a 2018 study published in the American Journal of Preventive Medicine, daily e-cigarette use doubles a person’s risk for a heart attack. If you quit, however, the risk begins to fall very quickly. “After just one day, your heart attack risk starts to decrease thanks to the lowering of blood pressure, rising blood oxygen levels, and reducing the negative influence on cholesterol levels and the formation of blood clots,” Dr. Djordjevic says.

Two days later: Senses begin to improve

Vaping, like cigarette smoking, can blunt your senses, reducing your ability to smell and taste. After just 48 hours without a puff, you may begin to notice your ability to taste and smell food has improved. Nicotine affects more than your brain; new research suggests nicotine can raise your blood sugar, too.

Three days later: Nicotine is out of the body

If you haven’t had nicotine withdrawals yet, you may start experiencing them by day three. “Nicotine leaves your body on day three, which is why withdrawal symptoms peak then,” Dr. Djordjevic says.

“You can have withdrawal symptoms of nicotine in the form of a headache, sweating, abdominal cramping, or nicotine cravings,” says Osita Onugha, MD, thoracic surgeon and director of thoracic surgery research and surgical innovation lab at John Wayne Cancer Institute at Providence Saint John’s Health Center in Santa Monica, California.

One month later: Lungs begin to show how much healthier they are

Smokers often have a nagging cough or make a wheezing sound when they breathe that many refer to as a smoker’s cough. Smoking even e-cigarettes can badly impair your lung health and make fighting off infections difficult. Quitting, however, will help your lungs rebound. “After one month, your lung capacity improves; there’s noticeably less shortness of breath and coughing,” Dr. Djordjevic says.

After three months: Blood circulation has improved

Nicotine in cigarettes constricts the blood vessels in your skin and around your heart, 2016 research published in the journal Trends in Cardiovascular Medicine. The nicotine in an e-cigarette may be just as harmful. However, after you quit, your blood circulation will begin to improve, as blood vessels return to their normal diameter.

After nine months: Your lungs can fight infections again

“After nine months, lung health improves significantly thanks to the renewal of microscopic hair-like structures inside the lungs that help push out mucus and fight infections,” Dr. Djordjevic says. This could significantly reduce your likelihood of some infections and complications from illnesses like the flu and pneumonia.

After one year: Your risk of a heart attack is cut in half

Now that your blood vessels are returning to normal size, your heart rate is back to a safe pace, and your blood pressure is lowered, your risk for a heart attack is much lower than while you were still vaping. “After one year, cardiovascular risk reduces by 50%,” Dr. Djordjevic says.

After five years: Stroke risk is significantly lower

The long-term effects of better heart health and lower blood pressure grants you another significant benefit: Lower stroke risk. Compared to nonsmokers, e-cigarette users have a 71% higher risk of stroke, according to research presented at the 2019 International Stroke Conference. Quitting can lower that risk almost immediately, but the risks continue to fall with each passing calendar month.

A decade later: Lower cancer risks

A 2017 study published in Scientific Reports suggests e-cigarettes and vaping may lead to DNA changes and genetic mutations that can increase the risk of cancer. So the longer you avoid e-cigarettes, the healthier your body will be. “After a decade, lung cancer risk is reduced by 50%, as well as the risk of pancreatic, mouth, and throat cancer,” Dr. Djordjevic says. “After 15 years, your risk of developing coronary heart disease becomes the same as a nonsmoker’s. The same goes for the risk of developing pancreatic cancer.”

20 years later: It’s like you never vaped

There will come a day that the bad habit of vaping won’t have any lasting impact on your body and your health. “After 20 years, your risk factors will be similar to those who have never smoked or vaped,” says Dr. Djordjevic. If you’re ready to kick the habit, ex-smokers offer their best advice for quitting cigarettes.
