Heterosexual	Reference group	Reference group	Reference group
Gay	1.62 (0.89, 2.95)	2.18 (1.48, 3.21) ^b	1.79 (1.09, 2.93) ^a
Bisexual	1.88 (0.99, 3.56)	1.07 (0.66, 1.72)	3.53 (2.03, 6.14) ^b

Heterosexual	Reference group	Reference group	Reference group

Results were derived from six separate multivariable binary logistic regressions controlling for demographic characteristics. The comparison group in each model is no past-year drug use, not having multiple chronic diseases, and not having a mental health disorder in the past year, respectively. aOR Adjusted odds ratio, CI Confidence intervals, ^a Significant at P < .05, ^b Significant at P < .001
