Does marijuana effect pregnancy?

Yes: Can cause low birth weight and problems with development of the nervous system. Attention and memory problems have been reported.

In many ways: Small head size, smaller baby, possible learning disabilities (not confirmed yet).Higher risk of crib death after birth when you continue to smoke.In my state, the finding of any drug in the newborns system is justification for the state to place the child in foster care and prosecute you for injury to a child.
