E-Cigarettes & Vaping: Health Risks

The understanding of the health effects of e-cigarettes, commonly known as vapes, continues to evolve. While often marketed as a safer alternative to traditional cigarettes, public health officials and researchers are increasingly clear: no tobacco product, including e-cigarettes, is safe. This is particularly crucial information for pregnant women, young adults, and those who have never used tobacco products.

Nicotine and Pregnancy

Most e-cigarettes contain nicotine, the highly addictive substance found in cigarettes, cigars, and other tobacco products. As of February 22, 2026, scientists are still actively studying the specific impacts of vaping on pregnancy and pregnancy outcomes. However, current evidence strongly advises against any tobacco product use during pregnancy. The Centers for Disease Control and Prevention (CDC) emphasizes that even the use of e-cigarettes is not considered safe in these circumstances.

E-Cigarettes and Existing Smokers

The CDC acknowledges a potential, though still under investigation, benefit for adults who already smoke. If used as a complete substitute for smoked tobacco products, e-cigarettes may offer some harm reduction. However, it’s vital to understand that no e-cigarette has been approved by the Food and Drug Administration (FDA) as a smoking cessation aid. More research is needed to determine the short- and long-term health effects of vaping, and to assess its effectiveness as a tool for quitting smoking.

Health Risks Beyond Nicotine

Recent research highlights that the risks associated with e-cigarettes extend beyond nicotine exposure. A April 2025 study led by Johns Hopkins Medicine analyzed data from nearly 250,000 individuals over four years. This analysis revealed a link between exclusive e-cigarette use and a higher risk of developing chronic obstructive pulmonary disease (COPD) and high blood pressure. This finding underscores that vaping is not a harmless activity, even for those who have never smoked traditional cigarettes.

What are E-Cigarettes?

E-cigarettes are known by many names – e-cigs, vapes, vape pens, and electronic nicotine delivery systems (ENDS). They come in a variety of shapes and sizes, but the common thread is that most contain nicotine. The CDC provides resources to help the public understand the facts about e-cigarettes, their health effects, and the risks associated with vaping.

Protecting Youth from Vaping

A significant public health concern is the increasing prevalence of e-cigarette use among youth and young adults. The CDC’s “Empower Vape-Free Youth™” campaign aims to address this issue by encouraging educators to discuss the risks of e-cigarettes and nicotine addiction with students. The campaign provides resources such as fact sheets, conversation cards, and digital media to facilitate these important conversations. Educators are seen as key figures in protecting young people from the harms of vaping.

Lung Injury and Vaping

In the past, outbreaks of lung injury were associated with the use of e-cigarette, or vaping, products. While the specific causes of these outbreaks were investigated, they served as a stark reminder of the potential dangers associated with vaping.

The Bottom Line

The current consensus among health officials is clear: e-cigarettes are not a safe alternative to traditional cigarettes, and they pose health risks to all users, particularly pregnant women, young people, and those who have never used tobacco products. Adults who smoke may consider e-cigarettes as a potential harm reduction tool only if used as a complete substitute for smoked tobacco, but should be aware that no e-cigarette is currently FDA-approved for smoking cessation. Continued research is essential to fully understand the long-term health effects of vaping and to develop effective strategies for preventing and addressing e-cigarette use.

Individuals seeking to quit smoking or vaping are encouraged to consult with their healthcare provider to discuss evidence-based cessation options.
