Italian Study: Vaping Is Effective for Reducing Tobacco Use

On July 19, a recent study published in the journal "Addictive Behaviors" once again demonstrated the efficacy and safety of e-cigarettes in helping smokers reduce tobacco consumption and improve their lung health.

The study, titled "The Benefits of E-Cigarettes for Reducing Tobacco Use and Lung Health in Chronic Smokers Undergoing Lung Cancer Screening Within Six Months," aimed to determine whether e-cigarettes are considered effective and safe in supporting smoking cessation.

A total of 210 smokers aged 55 and older, who smoked an average of 10 cigarettes for at least 10 years, were recruited. They were randomly divided into three groups: one group received nicotine e-cigarettes, another received a placebo (nicotine-free), and the control group received no e-cigarettes. All participants underwent a three-month smoking cessation program, which included a cognitive behavioral plan to support their behavior change and increase their motivation to quit.

Data collected through self-reported measures, clinical assessments, and the Leicester Cough Questionnaire revealed significant differences in the number of cigarettes smoked daily among participants who continued smoking after six months. The nicotine e-cigarette group averaged 11 cigarettes per day, while the nicotine-free e-cigarette group averaged 14 cigarettes, and the control group averaged 13.5 cigarettes.

Among the group still smoking after six months, another notable difference was the significant difference in exhaled CO levels between the two groups (p < 0.025). Participants in the nicotine e-cigarette group had an average exhaled CO of 12.0, while those in the nicotine-free e-cigarette group had an average of 15.3, and the control group had 16.5. (From a health perspective, a lower exhaled carbon dioxide ratio is preferred).

Once again, e-cigarettes have been found to be effective for smoking cessation.

Finally, there was also a significant difference in nicotine dependence between the two groups (p < 0.032). All participants exhibited moderate to low dependence within six months; the average core value for smokers in the nicotine e-cigarette group was 3.12, while it was 3.32 for the nicotine-free e-cigarette group and 3.59 for the control group.

The researchers concluded that approximately 20% of the entire sample had stopped smoking after six months. Participants using e-cigarettes and nicotine had a lower smoking amount after six months compared to any other group (p < .020). Our data adds to the evidence of the efficacy and safety of e-cigarettes in helping smokers reduce tobacco consumption and improve lung health.
