Polygenic score for “ever smoking” (PGS<sub>smoking</sub>) was assessed using PRSice from a 2010 GWAS conducted by the Tobacco and Genetics Consortium.

EPFs included education levels of mother or father, perceived financial status, maternal warmth, and stressful events before age 18. We used logistic regression to assess the odds ratio (OR) for PGS<sub>smoking</sub>, EPFs, and their interaction terms in relation to ever smoking, adjusting for age, gender, and the five principal components. Among the 6969 EA participants (mean age: 74.3 years, 57% women), 55% reported ever smoking. Among the 2141 AA participants (mean age: 59.6, 67.3% women), 61.1% reported ever smoking.
