A Dangerous Combination: Vaping and Smoking Raise Diabetes Threats

A groundbreaking study has uncovered alarming news: vaping may significantly increase the risk of developing prediabetes, a precursor to type 2 diabetes characterized by elevated blood sugar levels. This research, featured in The American Journal of Preventive Medicine Focus, suggests that those who combine vaping with traditional cigarette smoking face an even greater danger.

E-Cigarette Use Skyrocketing Among Youths

E-cigarettes are becoming alarmingly popular among European youth, with a staggering 22% of 15- and 16-year-olds reported to be regular users, according to a 2025 study. Sulakshan Neupane, the study's lead author and a doctoral candidate at the University of Georgia, emphasizes, "As e-cigarette use rises swiftly, understanding their implications on overall health is crucial. This isn’t just a lung issue; it impacts metabolic health across the board."

Study Reveals Disturbing Findings on Diabetes Risk

The researchers analyzed extensive health data from the United States, exploring the connections between vaping, smoking, and diabetes risk. They found that e-cigarette users face a 7% higher risk of developing prediabetes compared to non-users. Those who also smoke conventional cigarettes experience a 15% increased risk, and the danger intensifies for dual users, soaring to a 28% increase when both vaping and smoking are combined.

Dual Users Face Unprecedented Diabetes Risk

When it comes to diabetes, dual users of e-cigarettes and cigarettes confront a 9% higher risk than non-smokers. In contrast, traditional smokers show only a 7% heightened risk for the disease. Notably, the study found no significant link between vaping alone and diabetes risk.

E-Cigarettes: A Hidden Health Threat?

Neupane warns that while e-cigarettes are often marketed as safer alternatives, this study suggests they may conceal serious, long-term health problems like prediabetes and diabetes.

Socioeconomic and Demographic Factors Play a Role

The research also identified several risk factors that could exacerbate the likelihood of developing prediabetes and diabetes among smokers, including being overweight or obese, identifying as a racial minority, and belonging to a low-income group.

Prior Research and Regulatory Responses

These findings are consistent with previous studies that have expressed concerns over vaping's health risks. Some health organizations and scientists have already linked vaping to prediabetes, prompting European governments to take action. For instance, Spain has recently enacted a ban on smoking and vaping in public spaces like restaurant terraces.

Limitations of the Study

While the research presents compelling insights, it does have limitations, such as the inability to establish direct cause-and-effect relationships between e-cigarette use and prediabetes. Moreover, it relies on self-reported data and does not factor in genetic predispositions, family diabetes history, or levels of physical activity.

As vaping becomes increasingly prevalent, it’s essential to remain informed about its potential health impacts. Stay tuned for more updates on this developing story.
