Brightly colored inexpensive and disposable electronic cigarettes and vapes continue to gain popularity. These devices smell nicotine -containing liquid in a vapor, people who breathe more than hundreds or thousands of puffs – which are usually called vepping. Report researchers Central science After a few hundred puffs, some disposable volatile devices released a greater amount of metals and metaloids compared to the old refillable e-cigarettes and traditional cigarettes, increasing the risk of user’s health problems.
Our study highlights the hidden risk of these new and popular disposable electronic cigarettes – neurotoxic leads and carcinogenic nickels and with dangerous levels of antimony – which emphasizes the need for urgency in enforcement. ,

Studies on early generations of refillable e-cigarettes (eg, refillable pens, box modes and pods) found that their heating components could release metals such as chromium and nickel ions in the interior liquid that then breathe the people of the vapor. It is potentially harmful to collect some metals and metaloids, which increases a person’s risk of cancer, respiratory disease, and nerve damage.
Although most disposable e-cigarette marketing is not authorized by US Food and Drug Administration, devices are widely available. Over the years, the sales of disposable e-cigarettes have overtaken the sale of old refillable veps, but have rarely known about the fundamental structure of vapor from new devices. Therefore, Palin and his colleagues assessed popular disposable e-cigarette brands to evaluate potential health risks they could pose to a user.
Researchers identified metal and metaloids inside seven disposable devices from the first three brands, in which fluids were compared with light and heavy levels of taste. The original unused fluids had low levels of ionic metals and metaloids, although some devices stunned the lead and antimony of high levels. The team detected the source of lead to copper alloys used for non-heating components, which leacks in e-facials. There was no fixed source in the antimony.
They then activated the disposable e-cigarette, which heated the inner liquid and built between 500 and 1,500 puffs for each device. The analysis of vapor determined that:
- The levels of ionic metals and metaloids, including chromium, nickel, and antimony, increased as the number of puffs increased, while ionic zinc, copper and lead concentrations initially elevated, and each device had different emissions.
- Compared to previous studies, most tested disposable e-cigarettes released high amounts of metals and metaloids in vapor compared to the old refillable veps.
- One of the disposable e-cigarettes was studied, which releases more leads during a day’s use compared to about 20 packs of traditional cigarettes.
Researchers assess the health risk faced by a daily user of these devices next time. For two of the disposable vaps, the team collected information on poisoning for chromium and antimony, which contains non -toxic and carcinogenic forms. Only the non-types of chromium, CR (III) was present, but the vapor was seen in the vapor, a mixture between the low toxic forms of the antimony, SB (V) and carcinogenic form, SB (III). However, the level of nickel in vapor from three devices and the level of SB in vapor from two devices was higher than the range of cancer risk. The vapors of four equipment had nickel and lead emissions that crossed the health risk threshold for diseases other than cancer.
Researchers tested only three of about 100 disposable e-cigarette brands available on store shelves. They say that the results are due to the current popularity and the widespread use of disposable e-cigarette products, especially among adolescents and young adults.
