Chronic worrying, anxiety and being prone to depression are key aspects of the personality trait of neuroticism. In this study, the researchers looked at how smoking and heavy drinking are associated with the trait. A person with high neuroticism is likely to experience anxiety or depression and may self-medicate with tobacco, alcohol or drugs as a coping mechanism.
