Nho was scheduled to present the research at the American Society for Investigative Pathology annual meeting in San Diego this month.
Can vaping cause lungs to collapse?
Smoking — and now vaping — are associated with an increased risk of bursting these blisters, leading to lung collapse. “At Johns Hopkins, we’re seeing a rash of collapsed lungs in younger people,” reports Broderick. “We always ask if they’ve been smoking, and they’ll often say, ‘No, I don’t smoke. But I do vape.’

Idiopathic pulmonary fibrosis (IPF) is a disease of unknown etiology with considerable morbidity and mortality. Cigarette smoking is one of the most recognized risk factors for development of IPF.
Is vaping worse than smoking?
1: Vaping is less harmful than smoking, but it's still not safe. E-cigarettes heat nicotine (extracted from tobacco), flavorings and other chemicals to create an aerosol that you inhale. Regular tobacco cigarettes contain 7,000 chemicals, many of which are toxic.
How long after vaping do lungs heal?
After two weeks: your circulation and lung function begin to improve. After one to nine months: clear and deeper breathing gradually returns; you have less coughing and shortness of breath; you regain the ability to cough productively instead of hacking, which cleans your lungs and reduce your risk of infection.

Background. Cigarette smoking has been shown to associate with the risk of developing idiopathic pulmonary fibrosis (IPF) with ever-smokers having a 60 % higher risk [1].
Can you live with pulmonary fibrosis?
A diagnosis of PF can be very scary. When you do your research, you may see average survival is between three to five years. This number is an average. There are patients who live less than three years after diagnosis, and others who live much longer.
Does vaping cause long term damage?
While the severe lung disease and related deaths that have been associated with the use of e-cigarettes give pause to some users, two UCLA Health pulmonologists caution that beyond the immediate concerns about illness, vaping poses longer-term threats in the form of nicotine addiction and potential lung damage.

Can 1 puff of a vape harm you?
Cardiac Surgeon Lucian Durham warns inhaling a single puff from a vape could make you his next patient at Froedtert and Medical College of Wisconsin. The lung damage he has seen in patients is the equivalent to someone smoking cigarettes for decades. "It literally can kill you the first time you try it," he says.
Does popcorn lung go away?
Can popcorn lung fix itself? The short answer to this is no. Bronchiolitis obliterans is irreversible. Once the damage happens, you can't fix it.
Does vaping cause popcorn lung? | Cancer Research UK
What is popcorn lung? Popcorn lung (bronchiolitis obliterans) is an uncommon type of lung disease, but it is not cancer. It’s caused by a build-up of scar tissue in the lungs, which blocks the flow of air.
Do fibroblasts die from nicotine?
The researchers then experimented with e-liquids containing different amounts of nicotine, an active component of e-cigarettes. In those studies, fibroblasts exposed to nicotine-free e-liquids underwent cell death while those exposed to nicotine-containing e-liquids showed increased viability, with higher concentrations of nicotine leading to a greater increase in viability. These cells also super-charged their expression of a protein that binds to nicotine, called the alpha 7-nicotinic acetylcholine receptor.
Does vaping help with fibrosis?
They found that when fibroblasts were exposed to e-cigarette aerosol extract, they were significantly more viable than those exposed to smoke extracts, suggesting that vaping— to a greater extent than tobacco smoking—could contribute to fibrosis by helping fibroblasts stay alive for an abnormally long time.
Does nicotine affect fibroblasts?
Because the overactive fibroblasts were found to also increase the expression of a certain nicotinic receptor, Nho said finding a way to inhibit the pathological functions of the receptor that is abnormally regulated by nicotine in e-cigarettes could help to de-activate the fibroblasts and reduce scar formation. Further research can help to test this idea and determine whether different e-cigarette brands or components have different effects on fibroblast activity.
Do fibroblasts die off?
In normal conditions, fibroblasts activate and proliferate when they are needed to heal a wound and then die off when no longer needed. In the case of lung fibrosis, fibroblasts become overactivated and then fail to die off, leading to a damaging buildup of scar tissue.
Does inhibiting nicotinic receptors slow scar formation?
The new study, conducted in cell cultures, also suggests that inhibiting a certain nicotinic receptor could help promote the death of overactive fibroblast cells and thus slow scar formation, called fibrosis, in affected individuals.
Does vaping cause lung damage?
Vaping is known to cause lung tissue injuries. While the study was not designed to uncover the mechanisms behind the serious lung injuries and deaths that have been linked with vaping, the findings shed light on how e-cigarettes may affect the crucial cell type that repairs lung injuries when they occur.
Can nicotine cause scarring?
Taken together, these findings suggest that e-cigarettes containing nicotine can potentially cause lung fibroblasts to become overactive and ultimately create scarring. The results further suggest this can happen both in healthy people and in people whose fibroblasts already have a tendency to grow out of control, such as those with idiopathic pulmonary fibrosis.
Is vaping bad for you?
Unless you have turned off all your electronic devices, stopped reading the newspaper and have no functioning television then you have probably heard that electronic cigarettes or vaping is really bad for your health. In fact, there is a small epidemic of users of these products that are getting hospitalized with life-threatening breathing problems.
Is nicotine bad for your lungs?
It is not a big surprise to the pulmonary medicine community that inhaling nicotine and oils would be bad for your lungs. The big surprise has been how slow the federal government has been in recognizing that this is just another wolf in sheep’s clothing.

What are the effects of smoking?
The recent tragic and alarming cases of severe lung disease are clearly cause for concern. A number of other health effects are also worrisome: 1 Nicotine is highly addictive and can affect the developing brain, potentially harming teens and young adults. Even some "nicotine-free" e-cigarettes have been found to contain nicotine. 2 Some substances found in e-cigarette vapor have been linked to an increased risk of cancer. 3 Teens who vape are more likely to begin smoking cigarettes. 4 Explosions and burns have been reported with e-cigarettes while recharging the devices, due to defective batteries. 5 Accidental exposure to liquid from e-cigarettes has caused acute nicotine poisoning in children and adults. 6 Vaping during pregnancy could harm a developing fetus.
What are the chemicals in e-cigarettes?

Pulmonary fibrosis is the formation or development of excess fibrous connective tissue (fibrosis) in the lungs. It is also described as "scarring of the lung".
Is lung fibrosis fatal?
Pulmonary fibrosis is a fatal, incurable lung disease in which the lung tissue hardens and ceases to transfer oxygen into the blood. It is assumed to be a kind of autoimmune reaction, triggered by inhaled particles (such as coal dust, metal dust, asbestos but also pesticides and detergents). It is a rare condition, but former smokers frequently exposed to the kinds of particles have an elevated risk of contracting it.
Is smoking cigarettes bad for you?
When you smoke cigarettes you are burning a solid, removing oxygen and replacing it with heated, dry, carbon dioxide and hundreds if not thousands of carcinogens that are known to have serious side effects. The end result will eventually be asthma, emphysema, chronic obstructive pulmonary disease just to name a few. I have seen the long terms effect of smoking... very very bad...

What is an end vape?
ENDS, also known as E-cigarettes and vaping devices, were originally developed as a replacement device for conventional tobacco cigarette smokers [1]. However, their success in the arena of smoking cessation has been very limited, and they remain unapproved as cessation tools due to a lack of data demonstrating efficacy relative to currently approved nicotine replacement therapies [2]. The aerosols produced by E-cigarettes are known to cause a variety of deleterious health effects, although more research and long-term studies are still needed [2]. E-devices have rapidly evolved since entering the international market in 2013, with vape pens, box mods, and pod-based devices being the most commonly used vaping devices in 2020 [3]. Although E-cigarettes are used in conjunction with conventional tobacco by many cigarette smokers (dual users), their sole use in young adults and adolescents has skyrocketed [4]. This is concerning as use of tobacco products had been declining worldwide for over 50 years, and now, a new generation of nicotine addicts is being created through these novel vaping devices through the use of appealing flavors and packaging [5]. Even more concerning is that children and teenagers who use E-cigarettes are more likely to smoke conventional tobacco [6].
What is the difference between evali and lipoid pneumonia?
a, bThe histologic distinction between exogenous lipoid pneumonia and electronic cigarette or vaping-associated lung injury (EVALI) is dramatic and distinctive. Exogenous lipoid pneumonia shows numerous lipid vacuoles a, most of which are much larger than individual cells. There is associated fibrosis in which many of the droplets are embedded. Occasional macrophages contain lipid droplets within their cytoplasm. However, the droplets are much larger and more variable (arrow) compared to EVALI, H&E, × 100. Larger lipid vacuoles are surrounded by several multinucleated giant cells and a foreign body giant cell reaction (arrowhead) b, a feature not seen in EVALI, H&E, × 200
Is vaping a lung disease?
Although lung diseases caused by vaping have been reported since the modern invention of the electronic cigarette , in the summer of 2019, patients began to present to health care centers at epidemic levels with an acute respiratory illness relating to vaping, which the Center for Disease Control termed E-cigarette or vaping product use-associated lung injury (EVALI). This review discusses electronic nicotine delivery systems as well as the etiology, clinical presentation, imaging findings, pathologic features, treatment, and long-term consequences of EVALI. We conclude with the practical impact EVALI has had on the practice of pathology.

Is vaping a respiratory disease?
In the summer of 2019, an acute, mysterious, and deadly respiratory illness related to vaping emerged, primarily in young patients, in the USA. Cases increased dramatically and peaked in late September 2019. The Center for Disease Control and Prevention (CDC) termed the disease causing this epidemic E-cigarette or vaping product use-associated lung injury (EVALI). Prior to EVALI, vaping had been associated with a variety of different pulmonary presentations ranging from lipoid pneumonia to diffuse alveolar hemorrhage, but at low numbers. In this review, we discuss electronic nicotine delivery systems (ENDS) as well as the etiology, clinical presentation, imaging findings, pathologic features, treatment, and long-term consequences of EVALI. We conclude with a discussion on the practical impact EVALI has had on the practice of pathology.

What is popcorn lung?
Popcorn lung (bronchiolitis obliterans) belongs to a family of lung diseases called interstitial lung diseases (ILD) . While you may not have heard of even the most common ILD, pulmonary fibrosis, Bonham says, “it’s one of the more common reasons we do lung transplants.”.
How long does it take to live with popcorn lung?
And the stats say that a patient has only an average of 5 to 7 years to live. The lack of comfort and knowledge of pulmonary fibrosis, including popcorn lung, leads to a high level of under-diagnosis. Patients will come with what they think are symptoms of emphysema, only to discover they have this other, more severe disease.
Is pulmonary fibrosis a scarring disease?
While distinct diseases, Bonham points out that in all types of pulmonary fibrosis, “there’s been injury to the lung, and then there’s an ongoing process of scarring. It’s just that lot of different things can lead up to it.”
Can you cure pulmonary fibrosis from a pet bird?
Eliminating exposure isn’t always a cure. For example, some people with pet birds develop pulmonary fibrosis from the feathers and dander. They get rid of their birds, but afterward, a few still see disease progression. That is, the scar tissue continues to build.
Is it worth working with pulmonary fibrosis patients?
Still, despite the challenges, working with pulmonary fibrosis patients feels worthwhile to Paul. “It’s nice to take care of patients who others aren’t comfortable taking care of. They need someone; it’s nice to be that someone.”
Can lung transplants remove scars?
No treatment can remove the scars already created. This leaves lung transplant as the last resort. But as Bonham bluntly tells her patients, “Transplant is not a cure, it’s a trade. You’re trading your advanced lung disease for all of the complications that can come from immunosuppression” — a different set of problems.
What is the chemical that can damage your lungs?
Acrolein: Most often used as a weed killer, this chemical can also damage lungs.
What is a vape pen?
With vaping, a device (typically a vape pen or a mod — an enhanced vape pen — that may look like a flash drive) heats up a liquid ( called vape juice or e -liquid) until it turns into a vapor that you inhale. “Vaping is a delivery system similar to a nebulizer, which people with asthma or other lung conditions may be familiar with,” says Broderick. ...
What to do if your lung hurts?
What to Do If Your Lungs Hurt. If you smoke or vape, don’t brush off chest or lung pain as something that’s normal. If you have pain or other symptoms associated with breathing difficulties, such as shortness of breath and chronic cough, it’s important to see a doctor.
What is the food additive used to deepen e-cigarette flavors?
Diacetyl: This food additive, used to deepen e-cigarette flavors, is known to damage small passageways in the lungs.
Does vaping affect the lungs?
Instead of bathing lung tissue with a therapeutic mist, just as a nebulizer does, vaping coats lungs with potentially harmful chemicals. E-liquid concoctions usually include some mix of flavorings, aromatic additives and nicotine or THC (the chemical in marijuana that causes psychological effects), dissolved in an oily liquid base.
