sweetangel, the reason the 2nd trimester is safe is because all of the vital organs and nervous system are formed
in the 1st
trimester. Narcotics would have a major affect on that development
in the 1st
trimester. During the 2nd trimester the baby is still affected and damage can still be done to the already forming organs. And the baby will, in essence, be taking the drug with the mother, no matter what stage of pregnancy.
