The American Heart Association has recently released a statement warning about the potential health risks that e-cigarettes, also known as e-cigs, may pose. These battery-operated devices produce vapor, which is inhaled by the user. While they were initially marketed as a safer alternative to traditional cigarettes, new scientific evidence is shedding light on the dangers of e-cigarette use, commonly referred to as vaping.

E-cigarette Liquids and Their Contents

Many e-cigarette liquids contain nicotine, a highly addictive substance that has been associated with numerous negative health risks, including cancer. In addition to nicotine, these liquids can also contain humectants like propylene glycol and vegetable glycerol, which are responsible for producing the vapor, as well as flavorings and other chemicals that can pose further health risks.

The Growing Evidence of Health Dangers

Experts have been increasingly alarmed by the evidence pointing to the potential health dangers of e-cigarettes. In 2019, the US witnessed an outbreak of severe respiratory illnesses known as E-cigarette or Vaping-Use Associated Lung Injury (EVALI). Over 2800 people were hospitalized, and 68 people tragically lost their lives. Some of the chemicals used in vaping products, especially flavorings, have known toxic effects on the human body. Nicotine, which is common in most vaping liquids, not only has addictive properties but can also have acute effects on the cardiovascular system.

Gateway to Other Substances

A concerning trend associated with vaping is that individuals who use e-cigarettes are more likely to experiment with other tobacco products, including combustible cigarettes. Vaping has also been correlated with other substance abuse issues. This is particularly worrisome as many young people who have never used other tobacco products are adopting vaping.

Independent Health Risks of E-cigarette Contents

Nicotine, being a prominent component of e-cigarettes, is a major concern due to its addictive nature and acute effects on the cardiovascular system. Furthermore, vaping liquids often contain higher concentrations of nicotine compared to traditional cigarettes. Ingestion of these liquids, especially by children, can lead to seizures and severe muscle weakness, potentially impairing breathing.

Recent data has also raised concerns about the potential link between vaping and cancer. Heating nicotine in e-cigarettes may lead to the creation of carcinogens, increasing the risk of developing cancer. While the exact difference in cancer risk between vaping and smoking traditional cigarettes is unclear, evidence suggests that both carry substantial health risks.

Health Risks of Flavored Vaping Products

Flavored e-cigarettes have gained popularity, but some of the chemicals used as flavoring agents can have negative health effects. Diacetyl, a flavoring agent that produces a buttery taste, has been associated with a serious lung condition known as bronchiolitis obliterans.

It's essential to highlight that non-branded forms of vaping liquids have also been linked to health issues. The EVALI epidemic, characterized by e-cigarette or vaping-use-associated lung injuries, was connected to an adulterant agent known as vitamin E acetate. This agent made vaping liquids appear more concentrated and caused severe lung damage in many cases, particularly when vaping THC.

Understanding Long-Term Effects through Animal Studies

Given that e-cigarettes have only been on the US market for about 15 years, it will take time to understand the true long-term health impact. Conducting more animal studies is suggested to help predict potential long-term risks and better comprehend the effects of vaping on individuals with chronic diseases. Molecular studies can further enhance our understanding of how vaping affects human health.

The Bottom Line

Based on the scientific statement from the American Heart Association, e-cigarettes may pose several health risks. With the potential dangers of nicotine, harmful chemicals in vaping liquids, and the association with other substance use, experts recommend avoiding e-cigarettes due to their potential long-term health issues.
