I did he was fine he was the biggest of my three and they never said anything

I smoked before I knew I was pregnant a few times. And then twice around 7-9 weeks because I couldn't eat. I once had a physician that told me weed is a lot better than other things people are taking she said its beneficial. But little research has been done. Street drugs are risky because it can be laced but from a good dispensary is more reliable. Smoke and the amount of oxygen you and your baby are recieving can be a problem but if your blood test prove normal I don't think it's a big deal. They even tell cigarette smoking moms to try to quit gradually instead of cold Turkey. Or some they just recommend they don't smoke as many cigarettes while they're pregnant. But if you're comfortable with your physician I'd just ask if not I'd do some research online and in books.

Smoke entering the lungs is generally bad. Pregnant with an unborn whom basically shares what you put into your system is just not beneficial. It is up to the mother to make that choice but I am bias, I HATE SMOKE in my lungs .

Well there’s not any evidence it does or doesn’t cause harm. I wouldn’t risk the unknown personally. But I’ve had friends who did because of severe nausea. I feel for those moms more than if a mom was doing it just because.
