1/5 This week, my #SundaySpotlight on #PublicHealth science shines light on a new @JAMA_current study on #marijuana use during pregnancy. bit.ly/2L6P7vx

2/5 While researchers caution about potential confounders, their data very much suggest that #cannabis use during pregnancy is associated with increased risk of preterm birth.

3/5 The findings are particularly concerning since an accompanying study from @NIDAnews & @samhsagov finds that a growing number of U.S. moms-to-be are using #marijuana. bit.ly/2RsP6D6

4/5 Though our society is becoming more accepting of #marijuana use, this doesn’t make it safe. E.g. Cigarettes and alcohol, both legal, can cause harm to society as well as to people’s health. Read the related @NYTopinion on marijuana & youth. nyti.ms/2KVqPom

5/5 I hope those in favor and against ⬆️ #marijuana for adults can agree on this: We need more science on the effects of #cannabis, particularly when it comes to the developing brain.
