Research published in the journal JAMA Internal Medicine suggests that some pregnant women are using marijuana to self-medicate morning sickness.
Out of a study of 220,000 pregnant women, 2.3% were experiencing severe morning sickness. Out of these, 11.3% used marijuana.
Whilst the study found a link between marijuana use and morning sickness, it cannot be immediately concluded that pot is being used to self-medicate. Other factors, such as the possible contribution of marijuana to symptoms of nausea should not be disregarded.
Nonetheless, the study shows the importance of education on safe and effective treatments for morning sickness. The health effects of marijuana are unclear, but some studies report a link between marijuana use and low birth weight and impaired neurological development in newborns.
