For years the doctors have been saying that synthetic and natural vitamins are equally good for you. If that is true, then synthetic cannabinoids should have the same effect as natural and vice versa. Please go to Cannabisnews.com and check out the first comment by FOM on NORML's Weekly news bulletin. It seems that in mice prenatal exposure to cannabinoids actually promote the proliferation (growth) of neurons (brain and nerve cells). So, although the actual smoke from marijuana may be bad for your baby, the cannabinoids are helpful and build the brain. Back to brownies? No smoke involved, if you eat it. And get as much sleep as you can--you are going to need it. Have a Happy Holiday and a Happy, Healthy baby.
