My roommate is trying to get pregnant and she already might be .. Anyways I was talking to her and she was telling me that she's still going to continue to smoke weed through out her pregnancy. She's already a heavy pot smoker, I gave her the facts and researched all the problems it can cause and she doesn't believe. Why question is how do I get her to believe me without her thinking I'm trying to control her? 
I am currently pregnant myself and I refuse to have her do that around me or in my apartment.
