Data from the latest research from New Zealand confirms research published in 2016 by PHE that found vaping to be 95% safer than smoking.
The study was authored by three scientists Jinsong Chen, Chris Bullen and Kim Dirks from the School of Population Health, Faculty of Health Sciences and Medicine at the University of Auckland, who conducted the study with the aim of measuring the effects that e-cigarettes can cause, and comparing it with the harmful effects of cigarettes.
“Although some studies have shown harmful substances in e-cigarette liquids and e-cigarette vapor, information on the health effects of e-cigarettes is limited,” the authors explain. To measure these risks, the three researchers used the US Environmental Protection Agency’s health risk assessment model while measuring all the substances considered to have negative health effects.
Toxic substances in electronic cigarettes are less and have lower concentrations than in cigarettes.
For accurate assessment and measurement, dose response correlations and standard conditions of use are used while all factors are compared to the international guideline levels of each substance.
There are four toxic substances found in e-cigarette vapor (acrolein, diethylene glycol, propylene glycol and cadmium) and seven substances found in cigarettes (acetaldehyde, acrolein, formaldehyde, cadmium, CO, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), N'-nitrosonornicotine (NNN)).
In line with previous studies, regular cigarettes contain higher levels of toxic substances than the permitted levels. In addition, five toxic substances (acetaldehyde, acrolein, formaldehyde, cadmium, NNN) in regular cigarettes are found in higher concentrations than two substances (acrolein, e-cigapropylene glycol) in e-cigarettes.
Results show e-cigarettes are the safest option
“Our findings provide evidence that confirms the PHE study, but were carried out using a different methodology. Although we know that many smokers have smoked for decades, the aim of this study was to find out whether they could reduce their exposure to harmful substances by switching to vaping. It is fair to say that regardless of how long a person had smoked, their results after one year of switching to e-cigarettes were similar. This study suggests that e-cigarettes are safer than cigarettes and that e-cigarettes are safer for users than cigarettes,” the three authors concluded.
