Patients who used e-cigarettes were less likely to quit smoking.
An observational study found those who used e-cigarettes were less successful in quitting smoking than those who did not use e-cigarettes. An analysis of 237 propensity score-matched pairs, at 6 months, found 10.1% of e-cigarette users had quit, versus 26.6% of non-users. There were limitations to this study that suggest the need for a randomized trial.
PositiveTip: Like medications, the possibility exists that using e-cigarettes as a complete replacement for cigarettes, might be helpful.
