The growing transition from conventional cigarettes to e-cigarettes could transform the future of cancer across the USA.
As per a new study published in the JNCI Cancer Spectrum journal, scientists assessed data from a US federal health survey gathered between 2015 and 2023, a time period when e-cigarettes captured tremendous attention.
For the study, scientists assessed data from a US federal health survey collected between 2015 and 2023.
The results showed that cigarette smoking sharply declined across nearly every age group, with a sharp drop among adults aged between 18-34.
Simultaneously, exclusive use of alternative nicotine products, primarily e-cigarettes, was raised.
Lead researcher Kenneth Michael Cummings, a professor at the Medical University of South Carolina, stated the trend suggests many smokers are switching entirely to vaping rather than using both cigarettes and e-cigarettes simultaneously.
Dual use remained relatively stable, accounting for only 2% to 3% of adults during the study period.
Scientists created a population harm-reduction index to compare cigarette smoking with the use of non-combustible nicotine products.
An increased index suggests that more people are superseding traditional smoking with alternatives that may expose users to fewer cancer-causing chemicals.
However, adults aged 55 and older were much less likely to switch from cigarettes, despite standing to gain the greatest immediate health benefits from quitting combustible tobacco.
The research discovered that vaping has become more common as compared to smoking among young adults aged 18 to 24.
Scientists stated, "The red light, or take-home message, for me is that we're failing older people who smoke cigarettes," Cummings said. "These are people with decades of smoking behind them, and they're not changing to lower-risk noncombustible tobacco products as much as younger adults. They're the group that stands to gain the most immediate health benefits from the elimination of smoked tobacco.”
Notably, the research was funded by the US National Cancer Institute and the Food and Drug Administration, with no financial support from the vaping industry. Researchers noted that the long-term impact of today's smoking trends may not become fully visible for several decades.
