>> A higher number of pregnant women are getting high these days. That's according to new research from the Kaiser Permanente Northern California health care system which found marijuana to be the most commonly used illegal drug during pregnancy. Among girls under the age of 18, marijuana use during pregnancy rose from about 13% in 2009 to almost 22% in 2016.
Researchers found that over the same period, pot use rose 10 to 19% among pregnant women age 18 to 24. Health experts say there could be more lighting up because the legalization of medical marijuana has made people think of the drug as less dangerous, even during pregnancy. But previous research shows that prenatal marijuana exposure may impair fetal growth and neural developments.
