So a pregnant individual really has to be cautious about the different types of things that she eats and drinks with, the people that she interacts with because she doesn't want to get any type of pathogen that can basically cause damage to that developing fetus. She has to be careful about the places she visits and the things she does because she doesn't want to radiate that child. She doesn't want to give that child any type of damage as a result of the ionizing radiation. She wants to make sure that she follows a well balanced and a well nutritious diet and she doesn't want to ingest any type of dangerous agent for example, any type of medicinal drug that can cause harm to that fetus, any type of recreational drug or alcohol. And she obviously does not want to smoke. And that includes not only cigarettes, but it also includes marijuana, because marijuana has been shown to cause different types of damages to that developing embryo.
