If my husdband uses cocaine and we have sex. will it get on my system and affect my baby?

No only if the mothers uses , but I'm no Dr., never heard it affects the baby if the male uses.

i know that if the man drinks too much it can effect the sperm which would also effect the baby. was he doing cocaine before you got pregnant? he shouldn't have been doing drugs in the first place. it's a bad environment. but i'm guessing that drugs can do the same if i remember my sex ED still. i would think of it as smoking or drinking while pregnant. i will look it up though.
