Answer

Pregnant white women and Hispanic women had lower rates of illicit drug use (4.4% and 3%, respectively) than black women (8%). [31] Among women aged 15-44 years, the rate of cigarette use is higher among pregnant white women than among pregnant black or pregnant Hispanic women. [31]

Rates of substance use among pregnant women vary by age group, with past-month illicit drug and alcohol use highest among teenagers. The rate of illicit drug use among pregnant women aged 15-17 years was 16.2%, was 7.4% among pregnant women aged 18-25 years, and was 1.9% among pregnant women aged 26-44 years. [23]
