Electronic cigarettes, commonly known as e-cigarettes, are devices that deliver nicotine via aerosol and are reviewed here for their potential health benefits and risks. This assessment provides a balanced overview based on scientific evidence.
Benefits of Electronic Cigarettes
When used as an alternative to traditional tobacco products, e-cigarettes may offer the following advantages:

- Harm reduction for smokers: Switching to e-cigarettes could reduce exposure to carcinogens and toxins found in combustible cigarettes, potentially lowering cancer and respiratory disease risks.
- Aid in smoking cessation: Some studies indicate e-cigarettes can help smokers quit by delivering nicotine with fewer harmful byproducts and customizable nicotine levels.
- Reduced secondhand smoke exposure: The aerosol from e-cigarettes typically contains fewer pollutants, minimizing harm to bystanders compared to tobacco smoke.
Drawbacks of Electronic Cigarettes
Despite potential benefits, e-cigarettes pose significant health concerns:
- Nicotine addiction: E-cigarettes often contain highly addictive nicotine, leading to dependence and hindering complete cessation efforts, especially among youth.
- Respiratory and cardiovascular risks: Vaping can cause lung irritation, exacerbating conditions like asthma, and emerging evidence links it to increased heart rate and blood pressure issues.
- Youth appeal and gateway effect: Flavored options and marketing may attract non-smokers, increasing youth usage and potentially transitioning to tobacco products.
- Uncertain long-term effects: Due to their relative novelty, comprehensive data on long-term health outcomes, such as chronic disease links, remain insufficient and concerning.
