US Cigarette Smoking Falls to Record Low; Vaping and Nicotine Pouch Usage Increases
According to a study published in the New England Journal of Medicine, cigarette smoking among US adults has declined to an all-time low of 9.9% in 2024. Dr. Marc Siegel, a medical analyst, cautions that although this is a positive trend, the rise of vaping and nicotine pouch usage, both known for high nicotine content, could pose serious health risks. He emphasizes the potential gastrointestinal and heart problems linked to these products, stressing the impact of social media in attracting younger users.
Traditionally, many have viewed switching from cigarettes to electronic vapes as a healthier choice. However, a large-scale study from the American Journal of Ophthalmology indicates that such smokeless options might increase the risk for serious eye diseases when compared to completely quitting nicotine.
Researchers at Korea University College of Medicine analyzed health records of 179,273 adults from the Korean National Health Insurance Service. Each participant had smoked conventional cigarettes between 2011 and 2012, but had stopped smoking by 2018 or 2019.
The study aimed for an equitable comparison by pairing participants based on similarities like age, gender, health history, and lifestyle. This process ultimately formed a balanced group of 32,316 participants, categorized into two groups: those who completely ceased all nicotine products and those who switched to smokeless nicotine products, including vapes.
Researchers monitored the participants for about 4.6 years to track the development of various eye conditions, such as cataracts, glaucoma, and diabetic retinopathy. During this period, there were 6,328 recorded major eye disease events. The findings revealed that those who quit nicotine entirely had the lowest disease rate, approximately 41.1 cases per 1,000 person-years, while those using smokeless products like vapes saw rates rise to 44 cases.
The data indicated that transitioning to alternative nicotine products is linked to a 7% heightened risk of serious eye diseases compared to complete cessation. Notably, individuals who switched to vapes had a 24% higher risk of diabetic retinopathy, a condition affecting the eye’s blood vessels.
Furthermore, those who transitioned faced a 7% increased likelihood of refractive and accommodation disorders, which impair focusing ability. Researchers remarked that these findings challenge the belief that using noncombustible nicotine replaces the harm of traditional cigarettes.
However, the authors acknowledged some limitations in their research. Since it relied on analyzing past health insurance data, it doesn’t conclusively establish that vaping directly leads to eye damage. The study also depended on participants accurately reporting their smoking and vaping habits, which can sometimes be affected by inaccuracies or memory lapses.
In conclusion, researchers suggest that while the shift from cigarettes to alternative nicotine products may seem appealing, it doesn’t eliminate the associated risks for specific eye diseases.
