According to a new study, published in JAMA Internal Medicine, women are four times more likely to use marijuana while pregnant if they are experiencing severe nausea and vomiting.
Almost 300,000 women in the US were screened from 2009 to 2016, 8.3% reported using marijuana in the year prior to their pregnancy and 15.3% reported nausea and vomiting.
However, researchers would not rule out if drug use also contributed to nausea and vomiting, as they found clinicians were also more likely to diagnose this when women had been using marijuana to try and treat it.
This echoes a previous study of 4735 women in Hawaii from 2009 to 2011, which found prenatal marijuana use was more prevalent among those women with self-reported severe nausea during pregnancy.
But medical professionals warn the health effects of marijuana and pregnancy are still unclear.
However, as the researchers of this particular study point out, national guidelines recommend pregnant women “discontinue use” and instead resort to alternative means to treat nausea and vomiting.
