Despite a 10-fold decrease in overall exposure to carcinogenic particulate matter, researchers find increased levels of certain toxic metals in second-hand smoke from e-cigs.
E-cigarettes are healthier for your neighbors than traditional cigarettes, but still release toxins into the air, according to a new study from USC.
Scientists studying secondhand smoke from e-cigarettes discovered an overall 10-fold decrease in exposure to harmful particles, with close-to-zero exposure to organic carcinogens. However, levels of exposure to some harmful metals in second-hand e-cigarette smoke were found to be significantly higher.
While tobacco smoke contains high levels of polycyclic aromatic hydrocarbons -- cancer-causing organic compounds -- the level of exposure to these substances was reduced to almost zero in second-hand e-cigarette smoke, due to the fact that they do not burn organic material the way old-fashioned cigarettes do.
However, despite the lack of harmful organic material and a decrease in the majority of toxic metals emissions, e-cigarette smoke contains the toxic element chromium, absent from traditional cigarettes, as well as nickel at levels four times higher than normal cigarettes. In addition, several other toxic metals such as lead and zinc were also found in second-hand e-cigarette smoke -- though in concentrations lower than for normal cigarettes.
"Our results demonstrate that overall electronic cigarettes seem to be less harmful than regular cigarettes, but their elevated content of toxic metals such as nickel and chromium do raise concerns," said Constantinos Sioutas, professor at the USC Viterbi School of Engineering, and corresponding author of the study, which was published online on August 22 by the Journal of Environmental Science, Processes and Impacts.

I dont mean to sound rude...but what kind of ecig? A mod with silica and kanthol and pharmaceutical grade juice or blue cheap stuff?
Sioutas and Saffari compared the smoke from a common traditional cigarette brand with smoke from an Elips Serie C e-cigarette, one of the most popular European brands. The results could vary based on which type of cigarettes and e-cigarettes are tested, the researchers noted.

This doesn't surprise me.
My boyfriend did the e-cig thing for a little while, and the smell of it made me me gag. To me, it had a really strange, familiar smell... And it wasn't until he was weeks from quitting that it clicked in my head that when he blew the air out, it smelled like the medication in inhalers. I immediately told him to get rid of it. If you're smoking something that smells like a medication it's probably not good for you.
He pulled the "I'm addicted to it," line and didn't quit til later on, but I stayed away from it.
