New research suggests nicotine-based e-cigarettes may increase cancer risk despite being marketed as safer than smoking.Summary
Vaping is often marketed as a safer alternative to cigarettes, but new evidence suggests that nicotine-based e-cigarettes may increase the risk of some cancers. A review in the journal Carcinogenesis found that e-cigarette aerosols can damage DNA and trigger chronic inflammation, and contain potentially carcinogenic compounds like formaldehyde, acetaldehyde, and heavy metals such as nickel, chromium, and lead. While vaping is likely less harmful than smoking combustible cigarettes, it is not safe. Nicotine is addictive and may promote tumor growth, and vaping can exacerbate respiratory problems. E-cigarettes are not approved by the FDA as smoking cessation devices, and dual use (smoking and vaping) can be as harmful as smoking alone. For adolescents and young adults, nicotine can affect brain development, and vaping is associated with increased likelihood of later cigarette smoking. Parents should have direct conversations with their children about the risks of vaping.
