All e-cigarettes emit harmful chemicals, but some emit more than others: Study identifies two additional carcinogens not previously reported in e-cigarette vapor: While previous studies have found that electronic cigarettes emit toxic compounds, a new study has pinpointed the source of these emissions and shown how factors such as the temperature, type, and age of the device play a role in emission levels, information that could be valuable to both manufacturers and regulators seeking to minimize the health impacts of these increasingly popular devices.
