Finding F-0970

“The smoking of HNBT and e-cigarettes had no effect on the CO concentration, as already demonstrated by previous studies [9,24,37], because CO is a byproduct of the incomplete combustion of carbonaceous matter that occurs in TCs [38].”

Structure

Source: Electronic nicotine delivery systems (ENDS)
Factor: Carbon monoxide (CO)
Setting: home, PT
Study design: real-life measurement study in Portuguese homes: PM, carbon monoxide, volatile organic compounds and other pollutants measured while conventional tobacco cigarettes, heated tobacco products and electronic cigarettes were smoked indoors, against background periods without smoking (class 4)
Caveat: the authors explain it by carbon monoxide being a by-product of incomplete combustion, which these devices do not have
