Smokers who favor menthol cigarettes are more probably to become female, young, and less educated (Fernander et al., 2010; Lawrence et al., 2010). Compared with Caucasian smokers, drastically much more African American smokers (70 ) favor menthol cigarettes (Lawrence et al., 2010; Trinidad et al., 2010). Also, menthol is amongst the most preferred flavors of electronic cigarettes (McQueen et al., 2011). While there has been a Trisodium citrate dihydrate Inhibitor steady decrease in cigarette smoking, the usage of electronic cigarettes is growing at an alarming rate, with the use amongst US teenagers doubling from 2011 to 2012 (Center for Illness Control and Prevention, 2013). As a result, understanding the interaction between the sensory properties of menthol along with the reinforcing impact of nicotine is urgently essential. A lot of research have investigated the effect of menthol on smoking behavior; some reported that menthol facilitated the initiation of smoking and enhanced the dependence on nicotine (Hersey et al., 2006; Muscat et al., 2012; Nonnemaker et al., 2013), whereas other individuals reported that smoking menthol cigarettes was connected with a reduced responsiveness to medication, greaterdifficulty in quitting, and greater likelihood of relapse (Pletcher et al., 2006; Gundersen et al., 2009; Cubbin et al., 2010; Stahre et al., 2010; Levy et al., 2011). Having said that, quite a few other research have failed to determine a significant impact of menthol [see review by Palustric acid Hoffman and Simmons (2011)]. These inconsistencies are likely triggered by variations inside the study populations, study styles, and difficult-to-control environmental and socioeconomic variables. A further potential supply for the inconsistencies inside the literature may be the complicated pharmacological and affective effects of nicotine. For example, nicotine serves as a strong reinforcer of operant behaviors inside a wide variety of species, from rodents (Corrigall and Coen, 1989; Chen et al., 2007) to humans (Rose et al., 2003). Moreover, nicotine also induces sturdy aversive responses (Fowler et al., 2011; Fowler and Kenny, 2013). We lately showed that the sensory modality with the cue linked with nicotine delivery includes a robust function in figuring out the all round affective value of nicotine. In particular, we reported that olfactogustatory cues were related using the aversive effect of selfadministered nicotine (Chen et al., 2011). Additionally, genetic research have consistently shown that the gene cluster on chromosome 15 that encodes nicotinic acetylcholine receptor subunits 5, 3 and four, which underlies the aversive response to nicotineFrontiers in Behavioral Neurosciencewww.frontiersin.orgDecember 2014 | Volume eight | Article 437 |Wang et al.Menthol is actually a conditioned cue for nicotine(Fowler and Kenny, 20.
