Is vanilla vape safe if you're pregnant or trying?
If you're pregnant or trying to conceive, quitting vaping is the single most useful thing you can do for the pregnancy, whatever the flavor. Vanilla included. A new UC Riverside experiment gives a mechanistic reason to put it in the same bucket as every other vape: vanillin, the molecule behind vanilla e-liquids, knocked human embryonic stem cells off their normal developmental path at doses well below what killed them. A dish isn't a pregnancy, and the authors say so. But it fits what large pregnancy cohorts and current guidelines already conclude: no vape flavor has earned a safe label in pregnancy, and quitting lowers the odds of preterm birth and low birth weight.
