I am 37 weeks pregnant and have been smoking pot all through pregnancy only once or twice a day in the form of a little cone,but has been every day. is it safe to just go cold turkey now and stop or will that have a negative effect on baby as it is probably used to it? i just thought stoping now 3 weeks before birth than baby wont have withdrawls from it, is that right? what is safer to do now just continue smoking or to stop?
