i assume you are talking about illicit/illegal drugs since not all drugs are bad. antibiotics for instance. any pregnant woman who knowingly takes illicit drugs like cocaine or methamphetamines as an example is causing this innocent life unbelievable harm. this is definitely child abuse and if this child is born addicted or test positive for those drugs she will have to deal with the child-protective authorities and law enforcement and risk losing her child.
is taking drugs while your pregnant considered child abuse?
