E-Cigarettes Contain Hazardous Chemicals Linked to Severe Respiratory Diseases

Electronic cigarettes are battery-powered devices that heat a nicotine-containing liquid, which is inhaled much like a cigarette.

E-cigarettes have gained popularity as an alternative for traditional cigarettes. It has been found that three in four e-cigarettes use a flavored liquid that has been linked to severe respiratory disease.

Flavored Tobacco Products Are Popular Among Middle and High-School Children: CDC
Center for Disease Control said e-cigarettes and hookahs are available in a lot of kid-friendly flavors such as candy, fruit and chocolate that entice them.

‘Nicotine has only been the much-hyped addictive substance, but there are much more lung disorder-causing chemicals such as Diacetyl, Acetoin and 2,3-pentanedione in e-cigarettes.’

Unlike traditional cigarettes, the devices are not regulated by US authorities, leading to concern among some experts that they may be harmful to health -- and that their candy and fruit flavors may appeal to youths and put them at risk of addiction.

For the study in the journal Environmental Health Perspectives, scientists at Harvard University tested flavors that may appeal to young people such as Cotton Candy, Fruit Squirts and Cupcake.

They found that 75 percent of tested samples contained diacetyl, which when inhaled has been linked to the respiratory disease bronchiolitis obliterans -- sometimes called "popcorn lung" because over 10 years ago it was discovered in workers who inhaled artificial butter flavor in microwave popcorn processing facilities.

WHO Calls For Regulation of Flavored Tobacco Products
More than 170 countries were taking up measures Friday to regulate flavored tobacco products out of concern they seek to get young people addicted to nicotine.

Of the 7,000 varieties of flavored e-cigarettes, researchers focused on testing 51 types sold by leading brands for the presence of diacetyl, acetoin and 2,3-pentanedione, two related flavoring compounds that are listed as 'high priority,' because they may pose a respiratory hazard in the workplace, the study said.

In a lab testing environment, each e-cigarette was attached to a device that drew air through the e-cigarette for eight seconds at a time, with a resting period of 15 or 30 seconds, to mimic the action of a human smoker.

Water Pipes, E-Cigarettes may Lead to Increased Tobacco Use
A recent study has revealed that the use of e-cigarettes and alternative tobacco products may lead to increased tobacco use.

The air stream was analyzed, and at least one of the three chemicals was detected in 47 of the 51 flavors tested, according to the report.

Diacetyl was detected above the laboratory limit of detection in 39 of the flavors tested. Acetoin was detected in 46 flavors, and 2,3-pentanedione was found in 23 of the flavors.

FDA Hitting Milestones in Tobacco Law
FDA so far has taken many important steps to protect the public from tobacco products, says Lawrence Deyton director of FDA Center for Tobacco Products.

"Since most of the health concerns about e-cigarettes have focused on nicotine, there is still much we do not know about e-cigarettes. In addition to containing varying levels of the addictive substance nicotine, they also contain other cancer-causing chemicals, such as formaldehyde, and as our study shows, flavoring chemicals that can cause lung damage,” said study co-author David Christiani, a professor of environmental genetics.
