Cannabis while #ttc?

Hi ladies,

A friend of mine is about 4 months pregnant and was smoking up until the day she found out she was pregnant! I know that some women have had a drink or two before they found out and everything is fine, but I can't help but wonder..I should also mention that Evey "once in a while " she will take a hit when she isn't feeling well ( or so I've been told ). I've asked a few people what they thought and I've heard both sides of the argument, so I thought I would bring the topic here.. Has anyone used cannabis ( recreationally or medically ) before or while they were pregnant? And if so, did it affect the baby?
