How dangerous is secondhand vapor from electronic cigarettes
compared to secondhand smoke from regular cigarettes?
Researchers analyzed particles produced by both products to try to find out. The experiments were conducted in offices and rooms, with the atmosphere and smoking procedure designed to simulate real-life conditions. The volunteer subjects smoked regular cigarettes and e-cigarettes, and the researchers collected particles in the indoor air and studied the chemical content and sources of the samples.
After analyzing all of the data, the researchers found a 10-fold decrease in exposure to harmful particles from e-cigarettes compared to normal cigarettes with close-to-zero exposure to certain organic carcinogens.
But the news was not all positive. E-cigarette smoke produced significantly higher levels of specific metals including nickel. The researchers say overall their findings show electronic cigarettes appear to be less harmful, but the spike in toxic metals is a concern and should be considered during the debate over regulating the devices.
The study has been published in the Journal of Environmental Science, Processes and Impacts.
