Using marijuana to treat morning sickness during pregnancy could damage an unborn baby’s brain, a new study says.

Marijuana has been legalized in a number of states and attitudes toward its use have become more permissive. More women are using the drug during pregnancy, in part because of its reported ability to help relieve morning sickness. According to the Centers for Disease Control and Prevention (CDC), one in twenty women in the United States report using marijuana while pregnant. However, little is known about the effects it has on their children, although recent research is slowly shedding light on the matter.
