The OP's question was about known effects to a fetus; you've responded with "you shouldn't
You've voiced your opinion a stoned mom = a stoned fetus, even though medical professionals and scientists can't even agree on, nor document that position.
Maybe I juice... what about that? Research shows little to no psycho-activity to pass-on to anyone.
IMO, you haven't really tried to "reason with" or "rationalize" with anyone here, you've attempted to proselytize your personal morality, based on pure opinion.
The fetal choice argument applies to any/all substances consumed by a pregnant woman. Guess what? I don't give my unborn kid any options as to what other medicinal herbs I take, nor nutritional veggies I put in my morning smoothy. He didn't get options about the anti-biotics prescribed for the viral labrynthitis I developed in my first trimester, nor the second round I took for the severe kidney infection I had back in January. I've had iron deficient anemia and low protein throughout my pregnancy; my fetus didn't get the choice to consume red meat, or dairy, even though he might have wanted to be a vegan
That's the nature of being a fetus, completely dependent upon another's body, incapable of survival on one's own.
Since significant brain development/activity does not occur until the third trimester (again with the science), I'm not sure what choices he would have made at that point without the neurological capacity to do so.
Upon his birth, I have/get to choose whether or not he will receive Vitamin K to prevent against bleeding disorders. I'm not thrilled with his virgin gut being colonized with anything other than my natural antibodies, but have opted for oral drops, rather than the intramuscular shot, as it has been correlated with increased bleeding disorders. Again - HARM REDUCTION.
I also have the choice about the anti-biotic eye ointment administration when he's born. I am allergic to said antibiotics, so there's a strong likelyhood he will be too. I'm opting out of that, even though he may have to take an alternate treatment should he develop a bacterial eye infection. I'm making the best choice I can, using a risk/benefit analysis approach to the issue.
As he grows into a toddler, I have the choice about vaccines...
Point being, his father and I have a whole host of difficult choices regarding our child. These choices started upon conception and no matter how difficult, we must shoulder our parental responsibility as a matter of duty.
However, if you even think for one minute I make ANY decision related to this child I struggled to conceive for THIRTEEN YEARS uninformed or that I take any related decision lightly in any stretch of the imagination, you are plain wrong.
You also seem to ignore the fact there'd be no fetus to think about if I'd continued on without treatment. That's not an opinion, but a fact according to specialists with medical degrees and research backgrounds given the state my body was in shortly after conception.
Since my shoes are still sitting right here, I know you haven't taken two steps in them, let alone walked a mile. Gods forbid you'd ever be in a position to choose life or death for your unborn child while putting what anonymous internet posters might think about that choice before the current state of the available research on the topic!
I'm not here to try and convince anyone else on what their course of action should be relating to their pregnancy. I simply shared the difficult choice I made to try and carry my baby to term, rather than opt for in-utero death.
When/If my child asks, "mommy, why did you take MY choice away from me regarding cannabis consumption while you were pregnant?" I think I can feel secure in telling him, "because honey, Daddy and I tried to have you for roughly 1/3 of our lives; we really WANTED you and LOVED you even though we hadn't yet met you, and our doctors said it would be our best option to have you come out alive and healthy. I know that might not seem fair, but we made the best decision we could under the circumstances, given all the information we had at the time. We did the absolute best we could for you - then, now and always."
