Neuroticism, one of the five most famous high-order personality traits, is highly associated with nicotine addiction, according to a study published in the journal addictive behavior.

It is well known that neuroticism (the tendency to experience anxiety, worry, fear, anger, depression, and other negative emotions) is associated with a higher likelihood of drug use, including cigarette / nicotine addiction. The purpose of this study, entitled "the effect of neuroticism on e-cigarette dependence and the impact of beliefs about use and quit smoking on both flammable and e-cigarette users", was to determine whether the same was true of e-cigarettes.

The researchers analyzed data collected from a cross-sectional survey of 437 traditional and e-cigarette users. The pooled results do show the relationship between neuroticism and e-cigarette dependence, which is not surprising given that most e-cigarette users are former smokers.

"The results showed that neuroticism was significantly positively correlated with e-cigarette dependence (Δ R2 = 0.02, P < 0.001), expectation of negative effects on e-cigarette (Δ R2 = 0.03, P < 0.001), and smoking cessation disorder (Δ R2 = 0.10, P < 0.001)," the study Abstract wrote

The researchers conclude that further research is needed on the role of neuroticism in cigarette and e-cigarette addiction.
