WHO ELSE WOULD SMOKE?:

Long-Term Smoking Might Change Your Personality (Lacy Schley | July 5, 2019, Discover)

The paper outlines a series of five different long-term studies -- four in the U.S. and one in Japan -- that collectively surveyed about 15,500 people. Experts at a handful of different universities started the projects to track a whole host of things over time, like physical and mental health, relationships, behavior, etc. But for the purposes of this paper, the authors were only interested in the link between personality and smoking.

In each of the different studies, participants, who ranged in age from 20 to 92 years old, filled out a questionnaire that asked them about their smoking habits. The surveys included questions meant to assess where the participants fell on a spectrum of five personality traits, often called the Big Five: openness, extraversion, agreeableness, conscientiousness and neuroticism. Then, anywhere from four to 18 years later (depending on the studies), the same participants filled out the same survey again. Researchers flagged those who had quit smoking since their first survey and put them into their own "smoking cessation" group.

The results showed that, overall, people who smoked were more likely to report becoming less extraverted, open, agreeable and conscientious over the years, while also becoming more neurotic.
