New study links vaping to increased cancer risk

A recent study published in the journal Carcinogenesis has raised significant concerns about the safety of e-cigarettes.

Researchers at the University of New South Wales conducted a comprehensive meta-analysis of over 100 global studies, concluding that nicotine-based vaping is likely to cause lung and oral cancers.

Unlike previous research that compared vaping solely to smoking, this study assessed vaping on its own merits, identifying harmful volatile organic chemicals and heavy metals in aerosols.

These substances contribute to DNA damage, chronic inflammation, and oxidative stress, which are well-known precursors to tumor growth.

A major point of discussion is the latency gap; because vaping is relatively new, we lack decades of long-term human data.

The study also highlights the risks of dual-use, where individuals both smoke and vape, potentially increasing cancer risk four-fold compared to smoking alone.

Ultimately, the experts argue that while vaping may contain fewer chemicals than traditional cigarettes, it is not a harmless habit.
