- The study was a randomized clinical trial comparing the effects of switching from cigarettes to a pod-based e-cigarette with 5% nicotine versus 0% nicotine over 6 weeks.
- Primary outcome showed no significant difference in NNAL levels at 6 weeks, though a trend toward lower levels was noted.
- Participants using the 5% nicotine e-cigarette had a significantly higher abstinence rate from cigarettes (36.5%) compared to the 0% group (11.5%).
- The 5% nicotine group had higher cotinine levels but showed reduced exposure to toxicants like acrylonitrile and acrolein, indicated by lower levels of CYMA and 3HPMA.
- No significant differences were observed in the number of cigarettes per day or exhaled carbon monoxide between groups.
- Conclusions suggest that nicotine-delivering e-cigarettes may reduce toxicant exposure and aid smoking cessation compared to non-nicotine devices.
