not many studies have been done on it but for some that have smoked during a pregnancy so 1st hand smoke hasn't effected the baby so i don't think 2nd hand at a concert once would harm your baby much, but please do not smoke marijuana while pregnant. I'm not saying you do just saying in case other read the qusiton. doesnt seem to be any proof that it does effect the baby its jsut best not to risk it. but i do believe marijuana should be legalized and all that. i love marijuana but not for pregnant women or for children under 18. should be legalized for responsible use only. but again i woudln't worry about it but make sure u don't smoke or be around it till your not pregnant and don't have your child around it at all please.
