In states where it's legal, like 7% of pregnant people use cannabis while they're pregnant. There are receptors both in the placenta and in the developing fetus's brain that can be seen and attached to by THC. We have some older observational studies that suggest a fraction of the THC that's in the parent actually ends up in the fetus,. Maybe around three to seven times less. It's the fetus. This is such a dumb question. Is the fetus getting high? Great question. We really don't know.
Many states have extremely punitive policies around cannabis and pregnancy. But researchers don't actually have great data on cannabis's harms.
