The Atlantic has reported on how children of divorce are more likely to become smokers:
Researchers at the University of Toronto weren’t able to prove that children of divorced parents turn to cigarettes as a coping mechanism from lingering childhood trauma. But they did find that people whose parents had divorced when they were children were at a significantly increased risk of initiating smoking.
Of the 19,000 U.S adults included in the study, the odds of having smoked 100 or more cigarettes increased by 48 and 39 percent for sons and daughters of separated or divorced parents, respectively. The “100 or more” metric is the CDC’s way of deciding who counts as a smoker (people who never reach that milestone get to be labeled “never smokers.”)
“Gender-specific association between childhood adversities and smoking in adulthood: findings from a population-based study” was published in Public Health.
