I support Daima's position. First, I smoked through both of my pregnancies and both boys (now 26 and 30 years old) are fine. Second, let me quote from a United Press International wire. (Oct 13, 2005, by Steve Mitchell) " Scientists said Thursday that marijuana appears to promote the development of new brain cells in rats and have anti-anxiety and anti-depressive effects.... The rats showed evidence of new neurons in the hippocampus dentate gyrus, a region of the brain that plays a role in developing memories...." In fact, if your friend drank during pregnancy, she could have PROTECTED her baby by smoking, as shown in NORML's "Cannabis and the brain: A user's guide". "Not only has modern science refuted the notion that marijuana is neurotoxic, recent discoveries have indicated that cannabinoids are, in fact, neuroprotective, particualrly against alcohol induced brain damage." The one problem with smoking, however, is that it produced both carbon dioxide and carbon monoxide, both of which are harmful. This can be amellorated by taking Vitamin E (the US Navy demanded that the submariners all take it because it improved performance in low oxygen environments). Also cannabis seeds are highly nutritious containing Omega-3 fatty acids that are good for developing brains and adult hearts.
