A recent report by two Israeli researchers, Gideon Koren and Rana Cohen, published in the Journal of Cannabis Research, presents the cases of four pregnant women suffering from severe morning sickness (hyperemesis gravidarum).
One of them describes: “In her second pregnancy, the HG [nausées matinales] started at 4 weeks with up to 70 episodes of vomiting per day, requiring repeated hospitalizations…”.
All of these women found that 2-3 puffs of THC-rich marijuana (~20% THC, 1% CBD) were helpful in reducing or preventing vomiting and reversing weight loss. The effect of inhaling small amounts of marijuana lasted for 2 to 4 hours, and then they resumed taking doses, for a total of 1 to 2 grams per day. It appears that the researchers did not recommend this method to patients, but agreed on similar doses independently.
The babies are now 4 years old and no developmental problems have arisen.
The authors emphasize that they have not proven that cannabis can be used safely during pregnancy, but their work highlights the possibility of using THC-rich cannabis to treat severe morning sickness.
