Introduction:
This study evaluates the impact of baseline e-cigarette use on smoking cessation rates in a national sample of two-year college student smokers.
Methods:
Participants were 1400 students from over 60 two-year colleges across 25 states who were current smokers enrolled in a web-assisted tobacco intervention (WATI) trial. Survey data were collected at baseline, 1-, 6-, and 12-months, with primary outcomes evaluated at 6-months.
Results:
At 6-months, baseline e-cigarette users were more likely to report cessation of traditional cigarettes compared to non-users (OR 1.39, 95% CI 1.002-1.92). Cessation was also associated with higher baseline confidence in quitting and greater time to first cigarette in the morning. Baseline e-cigarette use was not found to be associated with self-reported cessation of all nicotine/tobacco products (OR 1.09, 95% CI 0.75-1.58) nor biochemically verified cessation of all nicotine/tobacco products (OR 0.83, 95% CI 0.47-1.47). Higher confidence was again associated with both self-reported and biochemically verified cessation of all nicotine/tobacco products. Female gender was associated only with biochemically verified cessation of all nicotine/tobacco products at 6-months.
Conclusions:
Two-year college students represent a priority population for cessation interventions. The findings from this study highlight the complexities of evaluating the impact of e-cigarette use on cessation.

03:08Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
