answer:I’ll see if I can answer this for you. But I will have to make you wait for about 12 hours. I have to head to town in five hours and it’s 4 am where I am. But, to partially answer your question, there is no documented study that shows any detrimental effects on the foetus (fetus). But to put in perspective, if cannabis did have detrimental effects on fetal development, all those people who grew up smoking pot in the sixties and seventies would have produced a marked increase in the average of children with problems. I’ll sort out my research when I get home and find some useful information and links. Cheers, Indica Man
