There's a new study suggesting more pregnant women appear to be using marijuana, sometimes to soothe anxiety and morning sickness.

The study, published in the Journal of the American Medical Association, observed a sample of pregnant women in California.

Pot use among the study subjects climbed from 4.2% to 7.1% from 2009 through 2016.

According to the CDC, doctors caution marijuana's effects on a fetus aren't clear, but could include low birth weight and developmental problems.
