According to a study published in a medical journal, more expecting mothers in the United States are using marijuana. Moms-to-be primarily use in their first trimester.
There has been an increase in the percentage of pregnant women who reported using marijuana. There has been an overall increase from 3.4% in 2002 to 7% in 2017. Pot use in the past month shows an increase from 5.7% to 12.1% in the first trimester.
Pregnant women frequently reported more medical marijuana use in their first trimester opposed to the second or third trimester.
Researchers used data from 4,400 pregnant women and 133,900 nonpregnant women between the ages of 12 and 44. Participants answered questions about current pregnancy status and marijuana use.
Daily or near-daily weed use increased overall from 0.9% to 3.4%. Pregnant women also report using marijuana more days in 2017 than in 2002.
Participants were asked if a health care profesion recommended their marijuana use, starting in 2013. Between 2013 to 2017, 0.5% of past-month marijuana use was considered for medical-only purposes. This means that a doctor recommended it.
The CDC states that most congenital disabilities occur in the first trimester of pregnancy when the organs are forming. This is why marijuana’s effects on fetal growth could be more severe in women who use pot frequently, especially in the first two trimesters.
The results from the study are consistent with previous research that has shown an increase in weed use among pregnant women in in the United States from 2002 to 2014. This study further analyzes marijuana use in pregnant women across trimesters. However, the authors state these numbers could be an underestimate, as some women may not realize they’re pregnant.
