druglibrary.org/crl/default.htm has a couple of articles on smoking pot and being pregnant. The conclusion was that it did not hurt the baby. One study that I read found that the babies of pot smokers were more socially advanced than those of nonsmokers. I smoked through both of my pregnancies and my "boys" (the baby is 26) are fine--the elder just got a job as computer tech for our county's schools. No brain damage there! The main problem with smoking is the carbon dioxide and monoxide produced by the act of smoking. You might try a pot cookie to help your problems instead of smoking. If you do decide to smoke, take vitamin E. My dad was on submarines and the navy made all of the sailors on subs take it because it allowed them to function more effectively in high carbon dioxide atmospheres. I took 400 units a day while pregnant.
