Ich weiß nicht, ob die Studie hier schon mal gepostet wurde. Hab allerdings nichts gefunden.
Auf Grund meines Studiums befinde ich mich in der glücklichen Lage auf ein paar gesundheitswissenschaftliche Datenbanken zugreifen zu können. Wenn Interesse besteht, kann ich mich da öfters mal schlau machen, bzw. die Resultate auch mal grob übersetzen.
Hier mal die Ergebnisse (Abstract) zur Raucherentwöhnung mit Hilfe von E-Zigaretten, die im April 2011 veröffentlicht wurde. Das Ergebnis ist erfreulicherweise ziemlich optimistisch ;):

Background

Electronic cigarettes (e-cigarettes) are battery-powered devices that deliver nicotine without any combustion or smoke. These devices have generated much publicity among the smoking-cessation community and support from dedicated users; however, little is known about the efficacy of the device as a smoking-cessation tool.
Purpose

This study aimed to examine the effectiveness of e-cigarettes for smoking cessation using a survey of smokers who had tried e-cigarettes.

Methods

Using as a sampling frame a cohort of all first-time purchasers of a particular brand of e-cigarettes during a 2-week period, a cross-sectional, online survey was conducted in 2010 to describe e-cigarette use patterns and their effectiveness as a smoking-cessation tool. There were 222 respondents, with a survey response rate of 4.5%. The primary outcome variable was the point prevalence of smoking abstinence at 6 months after initial e-cigarette purchase.

Results

The primary finding was that the 6-month point prevalence of smoking abstinence among the e-cigarette users in the sample was 31.0% (95% CI=24.8%, 37.2%). A large percentage of respondents reported a reduction in the number of cigarettes they smoked (66.8%) and almost half reported abstinence from smoking for a period of time (48.8%). Those respondents using e-cigarettes more than 20 times per day had a quit rate of 70.0%. Of respondents who were not smoking at 6 months, 34.3% were not using e-cigarettes or any nicotine-containing products at the time.

Conclusions

Findings suggest that e-cigarettes may hold promise as a smoking-cessation method and that they are worthy of further study using more-rigorous research designs.
