Okay, here is some info I found:
First of all, smoking anything during pregnancy deprives the fetus of oxygen. Just as smoking tobacco is discouraged in pregnant women, so is smoking marijuana. Smoking any type of substance interferes with the fetus's blood supply. This can mean the fetus doesn't get enough oxygen, and s/he may be born smaller in both weight and length.
Smaller babies have a higher risk of other problems after birth, such as infections, severe jaundice, difficulty feeding, breathing problems, low blood sugar, difficulty regulating temperature, bleeding into the brain, and problems with vision.
Thank you for everyones opionions. Thanks to Melaine594. I too live in Canada.
Personally I wouldn't do it...I don't think there have been enough CONTROLLED studies to say with certainty whether or not marijuana causes birth defects. Aside from that, becuase marijuana is an illegal substance, unless you grow it yourself, you don't know where it came from...who knows what it's been laced with.
Thank you for your research JoyRenee
going to nursing school myself and studying in the maturnity course, i had to do a paper on just this!!! it causes birth defects, and it was prooven, i wish i oculd find the articles that i used to write the paper hun, but its somewhere off of my colleges website using their library, but now that im writting this, im going to check my computer for the bibliography to see if i can find the article, only if i saved it to the computer. honestly, i wouldnt smoke while being pregnant, i cant tell you what to do because i dont smoke pot to begin with, but i do smoke cigarettes, and i am going to quit as soon as i find out im preggo, but in a weird way i guess you can say i know what its like with the cravings and having to quit suddenly because i had to when i found out the last time i was preggo, but i had a m/c, so needless to say i started to smoke cigs alot more after that happened from the stress i went through., but seriously, just think about it before u decide anything., it could be harmful for the babies lungs while their still trying to develop, you know?? but its all up to you, nicole
