Formaldehyde is a simple organic molecule with important industrial uses; however it is a known carcinogen (cancer-causing compound) . Researchers have long known that formaldehyde is present in cigarette smoke, but it was only recently in 2014 that researchers determined that formaldehyde is also present in e-cigarette vapor. For this and other reasons, the U.S. FDA is now overseeing production and distribution of e-cigarettes.
The data below are compiled from several studies examining the levels of formaldehyde in cigarette smoke and low- and high-voltage e-cigarette vapor (increasing the voltage of an e-cigarette allows for increased nicotine intake) . The data in bar A are from individuals consuming 20 cigarettes a day. The data in bar B are from individuals consuming 3 mL of e-cigarette fluid a day when the e-cigarette is set to low voltage (n.d. = not detectable) . The data in bar C are from individuals consuming 3 mL of e-cigarette fluid a day when the e-cigarette is set to high voltage.
-Assuming e-cigarettes contain many similar chemical compounds to traditional cigarettes, what part of the respiratory system do they likely negatively affect?
