let me tell you about a little fear i have, and it may not be an unreasonable hypothesis either....

first of all id like to point out that lack of birth defects do not mean lack of problem. Birth Defects mean like blind, serious brain damage, missing fingers, that sort of not subtle thing. everyone whos born to later become a life long depressed person, or have a mental illness is catagorized as a perfectly healthy baby when they were born...those things are not seen as birth defects

now with that said, a fetus has a brain thats still devoloping right? its receptors are still forming, its neurons are still forming. how do you think its receptors are going to form when a mu agonist is in its devoloping brain? how do you know that wont cause it to devolop a lower reward pathway density and lower mu (endorphin)receptor density? i dont believe theres enough data to know. and if it does cause a negative change in receptor densities devolopment in the areas of the brain which opioids affect, that baby will grow up to experience more dysphoria and mental pain and less pleasure. that would be so horrible i dont even want to think about it. im no expert in this but i dont think the experts know and this is something i fear. correct me if im wrong but we just dont know what having extra 'artifical endorphins' if you will, would do to the devoloping areas of the brain that they affect
