Study Reveals Hazards of E-Cigarette Modifications Among Youth and Adults

A recent comprehensive study conducted by researchers at Georgia State University highlights a concerning trend in e-cigarette use: a significant majority of youth and young adults have altered their vaping devices, often in ways that could pose serious health and safety risks. The research, based on a national survey of nearly 2,000 e-cigarette users, found that over 84% of respondents reported modifying their devices, with many engaging in potentially dangerous alterations.

The study, published in Scientific Reports, emphasizes that many users modify e-cigarettes without understanding the associated dangers. Common modifications include changing device voltage or adding substances to the e-liquid, such as flavorings, nicotine, or cannabis. While some modifications like replacing a battery or heating coil are considered legitimate, unauthorized alterations—particularly to batteries—are risky. About 40% of youth users reported making battery modifications, which can lead to overheating, fires, or explosions. Indeed, past data recorded over 2,000 injuries from e-cigarette explosions between 2015 and 2017.

Lucy Popova, the study’s lead researcher, underscores the importance of public awareness. E-cigarettes remain the most popular tobacco product among youth, and their usage among adults is rising. Popova advocates for enhanced public health campaigns to educate users about the dangers not only of vaping but also of modifying devices. She also suggests that clear product labeling and instructions can help reduce unsafe modifications.

The findings reveal that a significant portion of young users create their own flavorings and add extra nicotine or cannabis, while also performing unauthorized battery modifications. These practices increase the risk of accidents and exposure to harmful chemicals, including heavy metals. Education and better safety information are critical to safeguarding users from these hazards, according to the researchers.
