More and more expectant mothers are using marijuana in states where it is legal, the results of a new study of California women suggests.
The proportion of women there who used marijuana in some form while they were pregnant nearly doubled between 2009 and 2016.
In many states, medical marijuana can be prescribed for treating conditions including severe nausea and pain – both of which may affect pregnant women – but the American College of Obstetricians and Gynecologists recommends women stay away from weed if they want to have a baby.
In 2018, marijuana will be legally available for recreational use, suggesting that that even more pregnant women may have access to and indulge in it.
The new research from Kaiser Permanente suggests that women know that their doctors would not approve of their marijuana use: Less than half of the women that tested positive for marijuana copped to using it when asked in a survey.
