How Can Vapes Affect Your Health?

The use of electronic cigarettes, also known as vaping, has grown exponentially in recent years. However, the long-term health impacts of vaping remain unclear.

Vaping exposes users to harmful chemicals like nicotine, volatile organic compounds, and heavy metals, which can damage the lungs and other organs. It can lead to addiction, impair brain development in adolescents, and potentially cause lung disease, heart disease, and cancer. The long-term health effects of vaping are still unclear but could include chronic respiratory and cardiovascular diseases.

This article will examine what are the health risks of vapinghow vaping compares to smoking in terms of risks, whether vaping is safe for young people, the specific chemicals in e-cigarettes that may be harmful, how vaping affects the lungs, potential long-term effects, signs of vaping-related health issues, and how to quit vaping.

What are the Health Risks of Vaping?

E-cigarettes heat a liquid called e-liquid or e-juice into an aerosol that is inhaled by the user. This e-liquid typically contains nicotine, flavorings, and other additives. When inhaled, the user is exposed to nicotine along with other concerning chemicals.

The most well-established health effect of vaping is exposure to nicotine. Nicotine is highly addictive and can harm brain development in adolescents. The amount of nicotine in e-cigarettes varies widely, but can often exceed the amount in traditional cigarettes.

Flavorings in e-liquids also raise health concerns. Many contain volatile organic compounds (VOCs) like diacetyl, which is associated with the serious lung disease popcorn lung. Thousands of unique flavorings are used, many with unknown health implications. 

The aerosol created by vaping also contains heavy metals like lead, tin, and nickel, likely originating from the e-cigarette device and heating coil. These metals can damage the lungs and other organs.

Some studies have begun to reveal links between vaping and lung disease, heart disease, asthma exacerbation, and even cancer. However, the long-term health effects of frequent vaping remain uncertain. Still, it is clear that vaping exposes users to a complex mixture of chemicals with the potential to harm health in multiple ways.

How Does Vaping Compare to Smoking in Terms of Health Risks?

Proponents of vaping often cite harm reduction and smoking cessation as key benefits of e-cigarettes. Vaping advocates argue that while not harmless, vaping is likely to be far less risky than traditional cigarette smoking. 

There is some truth to this – numerous toxic chemicals from cigarette combustion are absent in e-liquid aerosols. Relative to smoking, vaping seems to expose users to lower levels of carcinogens. Switching completely from cigarettes to e-cigarettes substantially reduces exposure to many dangerous chemicals.

However, the long-term health impacts of inhaling e-cigarette aerosols day after day for years remains unknown. Without this data, claims that vaping is inherently less risky than smoking are premature. While likely safer than smoking in the short-term, vaping may come with its own chronic health risks over time.

More research is needed to better understand the unique health impacts of long-term vaping and how it compares to smoking before definitive conclusions can be made.

Is Vaping Safe for Young People?

One area of broad consensus is that vaping is unsafe for youth. Nicotine poses dangers to developing brains and bodies. Teen vaping has skyrocketed in recent years, largely driven by the popularity of newer cartridge-based devices like Juul

Studies consistently show harmful effects of nicotine on cognitive development in adolescents. Animal studies reveal impaired attention, learning, and memory, along with lasting changes in brain structure and function. 

Young vapers are also more prone to nicotine addiction than adult users. Those who start vaping early have a higher risk of transitioning to smoking traditional cigarettes. 

Finally, the permanent effects of long-term vaping initiated during adolescence remain unknown. But brain and lung development could plausibly be impaired in ways that only manifest later in life.

In short, vaping should be avoided by youth due to nicotine’s potent effects on still-developing systems. Parents and educators need to be vigilant about keeping e-cigarettes out of the hands of teens and tweens.

What are the Specific Chemicals in E-cigarettes that are Harmful to Health?

While nicotine and unknown long-term effects pose substantial concerns, other specific chemicals in vaping aerosols also have the potential to harm health.

As mentioned, numerous flavorings contain volatile organic compounds (VOCs) that may damage lungs when inhaled. One example is diacetyl, which can cause bronchiolitis obliterans (popcorn lung). 

Trace amounts of toxic heavy metals like lead, chromium, manganese, and nickel have also been found in the aerosol. These likely originate from the heating coil and other device components. Inhaled heavy metals accumulate in the body over time and are associated with organ damage, cancer, and neurological effects.

Formaldehyde is another hazardous chemical sometimes formed due to excessive heating of e-liquids. Long-term inhalation of formaldehyde is linked to certain cancers.

While at lower levels than in cigarette smoke, these and other concerning chemicals underscore the potential for cumulative harm from chronic vaping. Further research is urgently needed to better characterize toxic exposures from e-cigarette ingredients and device materials under real-world conditions.

How Does Vaping Affect the Lungs?

Given inhalation as the route of exposure, the lungs bear the brunt of potential toxicity from vaping. Emerging evidence links e-cigarette use with respiratory harm, especially in people with existing lung disease.

For example, vaping may worsen symptoms and lung function in individuals with asthma. Studies show vaping increases airway resistance and inflammation in asthma patients. Flavored e-liquids may provoke more severe effects.

Vaping has also been implicated in outbreaks of serious lung injuries. For example, EVALI (E-cigarette or Vaping Product Use-Associated Lung Injury) has caused over 2,800 hospitalizations. EVALI can lead to severe shortness of breath, pneumonia, and respiratory failure. Though mainly linked to illicit THC vapes, EVALI demonstrates vaping’s ability to damage lung tissue. 

Long-term effects like popcorn lung and COPD remain theoretical concerns. While more data is needed, avoiding vaping is prudent for anyone with existing respiratory issues.

What are the Long-Term Health Effects of Vaping?

Given the relative newness of e-cigarettes, the long-term health impacts of vaping are not well characterized. Since most research has followed vapers for less than a decade, chronic effects beyond this time frame remain speculative.

However, some longitudinal studies are beginning to associate long-term vaping with increased cardiovascular and respiratory disease risks. For example, regular vaping may increase the chances of heart attack, stroke, and coronary artery disease. The risk of developing chronic lung diseases like emphysema also appears elevated in vapers compared to never-smokers. 

Cancer risks associated with long-term vaping are largely unknown. Many carcinogens are present at lower levels in vape aerosols compared to cigarette smoke. But some research detected DNA damage in oral cells of vapers, indicating cancer-causing potential. Other studies found vaping increases biomarkers and mutations linked to cancer.

While more research is urgently required, avoiding or ceasing vaping remains the most prudent option until the long-term health impacts are clarified. Those who do continue vaping should use proper precautions and follow-up regularly with a doctor.

A number of worrisome symptoms have been noted in vapers experiencing acute issues or lung injury from e-cigarettes:

  • Shortness of breath, difficulty breathing
  • Wheezing, coughing, chest pain 
  • Nausea, vomiting, diarrhea
  • Fatigue 
  • Fever

More serious symptoms associated with EVALI may include:

  • Severe shortness of breath
  • Rapid breathing
  • Blue lips or face 
  • Chest pain that won’t go away 
  • Confusion, trouble waking up 

Chronic bronchitis-like symptoms have also been noted in some vapers, like increased mucus production and persistent cough.

Individuals who develop any persistent pulmonary symptoms like cough, shortness of breath, or chest discomfort should promptly seek medical advice. Rapid worsening of symptoms should be treated as a medical emergency.

What Can You Do to Quit Vaping?

For those seeking to reduce vaping-related health risks, evidence-based smoking cessation strategies may help:

  • Nicotine replacement therapy like gum, patches, inhalers
  • Prescription cessation medication like varenicline, bupropion
  • Counseling, behavioral support, or group therapy
  • Cognitive and motivational techniques
  • Lifestyle changes to avoid triggers
  • Hypnosis, meditation, or acupuncture

A combination of medication and counseling is often most effective. Working with your doctor can help you craft the right plan for overcoming nicotine addiction.

It may also help to identify reasons for vaping like stress relief or socializing, then replace vaping with healthier alternatives that meet the same needs without nicotine. Patience and dedication to the quitting process are key. Having a strong support network can make the journey much smoother.

With the right resources and commitment, many vapers have successfully switched to a nicotine-free lifestyle. If you’re seeking help moving away from e-cigarettes, don’t hesitate to reach out for assistance. Your health is well worth the effort.
