Study Finds Making the Switch to Ecigs Reduces A User’s Exposure to Toxicants



A recently published study revealed some interesting results for those folks who have made the switch to electronic cigarettes.

The researchers findings showed that adults who wanted to get away from their tobacco cigarettes in favor of using e-cigarettes instead had very significant reductions in their exposure to acrolein, a toxicant found in cigarette smoke and carbon monoxide.

Even dual users, people who vape and still smoke periodically still showed a reduction in their exposure to carbon monoxide and acrolein.


How They Conducted the Study:


Hayden McRobbie, MB, PhD, professor of public health interventions at Queen Mary University of London, and his colleagues recruited 40 adults who wanted to stop using tobacco cigarettes. The participants were given a cig-a-like type of electronic cigarettes to use.

The scientists measured the carbon monoxide levels in the participants’ breath a week before they switched to e-cigs, the day they switched to vaping and once a week for the next four weeks for the duration of the study.

They also analyzed urine samples from the participants on the day they switched to e-cigs and four weeks after they switched to check for their bodies’ levels of acrolein.


Their Findings:


After fours week the study concluded, 33 of the participants were still using e-cigarettes, 16 were using only e-cigs while 17 participants were dual users.

The researchers found that from one week before they made the switch to four weeks after switching, the levels of carbon monoxide in the breath of those only vaping decreased by 80%.

For dual users, the carbon monoxide levels of their breath were reduced to 52%.

The urine levels of the participants who were only vaping, revealed that their exposure to acrolein had decreased by 79% and those who were dual users decreased their levels by 60%.

McRobbie hopes to find our more about the potential vaping may have to assist smokers in switching away from e-cigarettes. He noted in his results, “We found that e-cigarette use significantly reduced exposure to carbon monoxide and acrolein over a four-week period. The reduction was greatest in those who switched to e-cigarettes completely, but even those who were dual users at four weeks had reduced exposure to carbon monoxide and acrolein. These results suggest that e-cigarettes may reduce harm compared with conventional cigarettes, even in dual users, but longer-term studies are needed to confirm this.”
