Studies have been fairly limited so far, given the recency of e-cigarettes (relative to science's timescale). And the studies that we have seem pretty mixed: some showing benefit over other accepted smoking cessation methods, some not. Some showing higher relapse rates in the e-cigarette group. Nothing about that seems clear to me.
