U.S. health officials say they found a dramatic rise in the number of women who are hooked on opioids and delivering babies in hospitals. Opioid use during pregnancy can cause death of the mother or baby, preterm birth and infant withdrawal symptoms like seizures, excessive crying and breathing problems. In 1999, 1.5 of every 1,000 women coming to a hospital to deliver depended on or abused opioids. That translates to nearly 25,000 deliveries across all 50 states that year. Rates were highest in Vermont and West Virginia.
