I didn't smoke and wouldn't have even if I'd been a smoker during that time, which I wasn't. I was like Fengzi's wife and gave up everything, caffeine, alcohol, sushi and medicines included. If I'd colored my hair during that time, I'd have quit that, too. You just never know. My son was full-term and weighed an amazing 10 lbs, 7 oz., but I don't attribute that to my being compulsive during the pregnancy. I attribute it to the fact that his father is immense. I said "This is your fault" as the OR staff was all oohing and aahing at the baby's size after they wrestled him out of me by C-section and weighed him.

It's unlikely that studies will ever be done on this question, BFA. No one with sense is ever going to study vulnerable, developing fetuses and how they respond to cannabis. It's easier just to play it safe and not smoke for that comparatively short time, although there are people who do otherwise. Fengzi's point that no reasonable person would ever blow cannabis smoke into a baby's face is a good one.
