In 2016, 7% of pregnant women in a California study tested positive for marijuana use, which is nearly double the 4% who were using it in 2009. With the upcoming legalization, that number is sure to soar.
JAMA conducted a study, called Trends in Self-reported and Biochemically Tested Marijuana Use Among Pregnant Females in California From 2009-2016.
This study showed the numbers of pregnant women in California consuming cannabis rise nearly two-fold when compared to a previous study conducted in 2009.
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.
California was the first state in the US to legalize medical marijuana way back in 1996, but today it is legal in 29 states, and Washington, DC.
Given the fact that recreational marijuana is slowly but surely becoming more widespread, we could see the same stats appear in several other states like Nevada, Washington and more.
As you can see from the chart above, younger women are more likely to be smoking cannabis during their pregnancy, even up to 5 times than those over the age of 34.
Scientists have confirmed that there is still not enough conclusive evidence that cannabis does affect developing human fetuses, even though there are some evidence from animal trials.
One of the most perplexing foundings that researchers from the The Kaiser Permanente school of medicine is the stat showing how many women admitted to cannabis use, when compared to the number of those that tested positive.
Only about 30% of women which were tested admitted to their use, while well over 50% tested positive.
This is no surprise when you count in the fact that more than half of all Americans reported having tried marijuana at some point in their lives, and about 22 percent of those qualify as regular users.
