Popular e–cigarettes products found contaminated with Microbial Toxins

In a recent study, it is found that the popular e-cigarette products are contaminated with bacterial and fungal toxins that cause lung disease.  A study suggests that many e-cigarette cartridges and refilling e-liquids are contaminated with toxins spewed out by Bacteria and fungi.

Smoke from customary tobacco cigarettes is clearly filled with no deficiency of toxins. A portion of these toxins aren’t made by the burning of tobacco itself, however, yet originate from dead bacteria and fungi that contaminate the products eventually amid the production process. They incorporate endotoxins, which are found inside gram-negative microscopic organisms, and Glucans, which help structure the cell dividers of numerous fungal species.

The study found that 27% contained traces of endotoxin, a microbial agent found on gram-negative bacteria and that 81% contained traces of glucan, which is found in the cell walls of most fungi exposure to these microbial toxins has been associated with myriad health problems in humans, including asthma, reduced lung function and inflammation.

Dr David christiani, study author and professor of environmental genetics said, ‘Finding these toxins in e-cigarette products adds to the growing concerns that we have about the safety e-cigarettes’

The study additionally discovered that endotoxin focuses were higher in fruit-flavoured products, demonstrating that raw materials utilized in the production flavours might be a source of the contamination.

For this study, the researchers selected 37 e-cigarette cartridges, referred to as ‘cigalikes’ and 38 e-liquid products which can be used to refill certain cartridges from the ten top-selling U.S brands. The products were first classified into four categories like tobacco, menthol, fruit and other. As all the products were examined for the presence of endotoxin and glucan.

The investigation found that the contamination of the product might have occurred at any stage during the production of the ingredients. They examined that cotton wicks utilized in e-cigarette cartridges might be one potential source of contamination, as both endotoxin and glucan are known contaminants of cotton fibres.

The consumption of e-cigarettes has been increasing constantly, particularly among high school and middle school students. It’s evaluated that more than three million high school students use e-cigarettes in 2018, up from 220,000 in 2011. Past research from Harvard Chan School has demonstrated that chemical linked with severe respiratory disease are found in common e-cigarette flavours. In addition, research by HSPH investigators directed over numerous decades has demonstrated interminable lung impairment in populations exposed to airborne organic contaminants. However, as indicated by the authors, no research exists on the potential contamination of e-cigarettes with organisms or microbial toxins.
