My lady went in for an 8 week checkup. They tried to schedule her to see a therapist without even asking her, she called back and cancelled after finding out.
So the question is, does marijuana negatively effect fetus development? It’s extremely natural yet… it’s a problem. What do YOU think? Sauces appreciated because google is the devil.
That link goes to a study dated 1991 but I'm pretty sure that it was this one in 1987, which I remember because it was almost the only study of weed at all, and definitely the only favorable one. https://pubmed.ncbi.nlm.nih.gov/8121737/ Certainly the most persistent ethnographic study of only 45 babies for two months. Here's the backstory of that study, which continues to be popular as a justification to keep on smoking. Definitely rounds out the story as the smoking mothers had other important differences. https://undark.org/2019/08/28/jamaica-study-cannabis-researchers-pregnancy/
Three longitudinal studies showed more problems later in life. https://sitn.hms.harvard.edu/flash/2019/marijuana-e
A more recent meta analysis finds about half of studies showed adverse effects: https://pubmed.ncbi.nlm.nih.gov/35084479/
As we know, "studies" are frequently "flawed" and "more research needs to be done." This is certainly true of anything funded in the US in the years before medical marijuana started. No one who had positive results or even wanted to see if there were any positives got funding. Then, when it became obvious that medical use was inevitable (and the Reefer Madness approach faded out), this situation changed to looking for diseases affected by marijuana. So, a new body of politically charged research. Now with widespread legal use, there is yet another complicating factor, which is the high THC content of commonly available products. And edibles, and vaping, this is not what people in the past were using. "Not your mother's marijuana." https://pubmed.ncbi.nlm.nih.gov/25459779/
With all this, I'd say don't do it.
