More pregnant women are using meth and opioids, study finds

Amphetamine and opioid use in pregnancy increased substantially over the last decade in the United States, a new Michigan Medicine-led study finds. And a disproportionate rise occurred in rural counties.

The rate of opioid use also quadrupled from 1.5 per 1,000 delivery hospitalizations in 2004-2005 to 6.5 per 1,000 delivery hospitalizations in 2014-2015, according to the findings published in the American Journal of Public Health. The study sample included about 47 million deliveries occurring in U.S. hospitals over the 12-year-period.
