What is EVALI?

EVALI, an acronym for E-cigarette or Vaping Product Use-Associated Lung Injury, is a critical and concerning condition affecting the lungs of individuals who have used e-cigarette or vaping products. This condition emerged prominently in 2019, leading to a significant public health investigation and response. EVALI is characterized by severe respiratory distress and can be life-threatening, necessitating hospitalization for many affected individuals.

What Causes EVALI?

The precise cause of EVALI is complex and has been the subject of extensive research. However, strong evidence points towards additives and contaminants in vaping products as the primary instigators. The U.S. Centers for Disease Control and Prevention (CDC) has identified vitamin E acetate as a key suspect. Vitamin E acetate is an oil that is often added to THC-containing vaping liquids. When heated and inhaled, it is believed to coat the lungs, interfering with normal lung function and causing inflammation and injury.

While vitamin E acetate is considered a major factor, it's important to note that EVALI may not be caused by a single substance or product. Other additives, contaminants, or even the base ingredients in e-liquids, when inhaled, could potentially contribute to lung injury. Many of the patients who developed EVALI reported using illicit vaping products, often obtained outside of legal dispensaries or regulated markets. These products may contain undisclosed or harmful ingredients.

What are the Symptoms of EVALI?

The symptoms of EVALI can vary but often mimic other respiratory illnesses like pneumonia or bronchitis, making diagnosis challenging. Common symptoms include:

• Shortness of breath or difficulty breathing
• Chest pain
• Cough
• Fever and chills
• Nausea, vomiting, or diarrhea
• Fatigue

These symptoms typically manifest within a few days to weeks after starting or changing vaping habits. The severity can range from mild discomfort to severe respiratory failure requiring mechanical ventilation.

Who is at Risk for EVALI?

Individuals who use e-cigarette or vaping products are at risk. The risk appears to be higher among those who use:

• THC-containing products, especially those obtained illicitly.
• Products that contain vitamin E acetate.

However, it is crucial to understand that any vaping product, even those marketed as containing only nicotine, could potentially pose a risk if it contains harmful additives or contaminants. The long-term effects of vaping are still not fully understood, and emerging health concerns like EVALI highlight the potential dangers.

How is EVALI Diagnosed and Treated?

Diagnosing EVALI typically involves a combination of patient history, physical examination, and diagnostic tests. Doctors will inquire about vaping habits and symptoms. Imaging tests like chest X-rays or CT scans may reveal characteristic patterns of lung damage. Laboratory tests can help rule out infections and assess lung function.

Treatment for EVALI focuses on supportive care and managing symptoms. This often includes:

• Hospitalization
• Supplemental oxygen
• Corticosteroids to reduce lung inflammation
• In severe cases, mechanical ventilation to assist breathing

Many patients show improvement with prompt medical treatment, but some may experience long-term lung damage or complications.

Prevention of EVALI

The most effective way to prevent EVALI is to avoid using e-cigarette, vaping, or e-hookah products. If you choose to vape, the CDC strongly advises against:

• Modifying or adding any substances to vaping products that are not intended by the manufacturer.
• Using any vaping products, especially THC-containing products, purchased from informal sources like street vendors or illicit dealers.
• Using vitamin E acetate or other additives in vaping products.

For those struggling to quit vaping, resources and support are available through healthcare providers and public health organizations.

Ongoing Research and Public Health Recommendations

Public health agencies worldwide continue to monitor and research EVALI. The focus remains on identifying all potential contributing factors and educating the public about the risks associated with vaping. Regulations surrounding the sale and marketing of vaping products are also being reviewed and updated in many regions to enhance consumer safety. The CDC recommends that people who are concerned about EVALI should consider refraining from using all e-cigarette, vaping, and e-hookah products.
