Disposable e-ci******es, popular among teens and young adults, are not as harmless as they may seem. Recent studies have revealed that these devices release toxic metals like lead, nickel, and antimony into the v***r at levels significantly higher than those found in traditional ci******es. In some cases, a single day's use of a disposable v**e emitted more lead than smoking nearly 20 packs of regular ci******es. These metals are known to cause cancer, nerve damage, and respiratory issues, raising serious health concerns.
The source of this contamination lies in the construction of the devices. Many disposable v**es contain metal components such as heating coils and structural parts made from leaded bronze, which can leach lead into the e-liquid. Over time, as the device is used, these metals break down and are inhaled by the user. The longer the device is in use, the more metals are released, increasing the potential for harm.
This issue is compounded by the fact that many of these disposable v**es are not legally authorized in the United States but remain widely available. Their appeal, especially to younger users, is concerning given the significant health risks associated with their use. The findings underscore the urgent need for stricter regulations and enforcement to protect public health.
