A chemical in sweet flavoured e-cigarettes can cause
a severe respiratory disease known as popcorn lung.
There are almost 7,000 varieties of flavoured e-cigarettes containing nicotine used, in the United State alone. Diacetyl is a chemical which is found in around three-quarters of electronic cigarette brands. It causes bronchiolitis, obliterans, a respiratory disease commonly called popcorn lung after it was first discovered in workers who breathed artificial butter flavours in microwave popcorn processing plants. This chemical is used to add flavour to sweet snacks such as cupcakes, popcorn and candy floss. Health agencies says this chemical is not a health hazard in the products, but it can become lethal when heated up, as happens in an e-cigarette.
Researchers at the Harvard T H Chan School of public health discovered that among 51 types of flavoured e-cigarettes, have 75 percent contained diacetyl. In a simple test in a sealed chamber, the researchers found that the emissions from 39 of the brand were above levels considered to be safe.
America`s health watchdog, the Food and Drug Administration (FDA), is considering whether to start regulating e-cigarettes. Although the cigarettes don`t contain nicotine, they do include other chemicals including diacetyl that could be just as harmful, say the researchers
