Likelihood of current dual use (vs cigarette only use) and current ENDS use only relative to cigarette smoking, by sexual orientation, separately for male and female participants

Male Participants	Current dual use		Current ENDS use only
Sexual orientation	AOR (95% CI)	p	AOR (95% CI)	p
Bisexual	0.78 (0.28–2.12)	0.6233	0.72 (0.29–1.83)	0.4959
Gay	0.53 (0.23–1.20)	0.1250	0.71 (0.35–1.45)	0.3475
Heterosexual (Ref.)	1		1
Female Participants	Current dual use		Current ENDS use only
Sexual orientation	AOR (95% CI)	p	AOR (95% CI)	p
Bisexual	1.85 (1.19–2.87)	0.0062	1.40 (0.89–2.20)	0.1428
Lesbian	0.95 (0.49–1.84)	0.8785	0.98 (0.51–1.87)	0.9523
Heterosexual (Ref.)	1		1

Adjusted odds ratios (AOR) and 95% confidence intervals (CI) of lesbian/gay and bisexual participants were estimated from multinomial logistic regression for multiple tobacco use response (current dual use and current ENDS use only as opposed to current cigarette smoking only). Separate analyses were performed for male and female participants, with adjustment for age, race, ethnicity, education, income, employment status, and marital status.
