I'm pregnant and I want to know if it's harmful to the baby if I only smell cigarette smoke, but I'm not even around the smoker and directly inhaling the fumes? Or, by being able to smell it am I inhaling the toxic chemicals? I want to keep myself in the safest environments for my baby :/ Thanks for your answers 
The reason I ask this is because my boyfriend lives in an apartment where the tenants down below us smoke and I can smell it through an open window, if that makes any difference..
