<s>[INST] Hello, Im 15 weeks pregnant and just found out about a week ago. For the weeks i didnt know i ate lobster.... didnt drink too much water.... smoked marijuana a couple times, and drank probably once at my sisters wedding....and could have eaten a little better. Is this going to harm my baby? [/INST] Hi, I understand your query & concern.  Eating cooked lobster is not supposed to be harmful. So is the case with a solitary Chat Doctor.  It should not be regular.  But smoking Marijuana is definitely harmful in early weeks of pregnancy when primitive brain is formed. You should consult an embryologist, in case you had regular smoking of marijuana in the early pregnancy to decide about continuation of pregnancy.  Thanks. </s>
