Multinomial logistic regressions explored sociodemographic\/health characteristics associated with past\u2010month co\u2010use and cannabis\u2010only use (vs. tobacco\u2010only).

Cannabis\u2010only use (vs. tobacco\u2010only) was more likely among those with mental illness, yet less likely among those with good or fair\/poor health than excellent\/very good health.
