SRH = sexual and reproductive health. Results are weighted proportions (%) using SRH services by substance use frequency for all young women and for sexually-experienced women. P-values (p) from unadjusted chi-square tests.

Assessed only among those participants who reported alcohol use in the previous 12 months. Hrs = hours.

Other illicit drugs may include crack, cocaine, and nonprescription injectables.
