The aim of the current review is to provide, in one place, an overview about the association of suicide with 1) current smoking, 2) smoking cessation and 3) use of smoking cessation medications. Prior articles have specifically looked at each of these three associations (Leistikow & Shipley 1999; Breslau et al. 2005; Kessler et al. 2007; Licinio & Wong 2005); however, none has described how these three interrelate, nor possible biological and psychological mechanisms for these associations. The benefits of having such information in one place are twofold. First, as described below, some results thought to be due to one of these associations may, in fact, be due to a different association. Second, the strength of the data about validity and causes can be compared across the three associations. The aim of the article is not to be comprehensive or critical, but rather provide a qualitative overview of these three associations. The conclusions are based on the author’s judgment.
