Question

which consequence can occur if a mother uses drugs during pregnancy?
allergies
high birth weight
longer term pregnancy
sudden infant death syndrome

Explanation:

Drug use during pregnancy can have serious impacts on the fetus. It has been linked to sudden infant death syndrome (SIDS). Allergies are not a typical direct consequence. High birth - weight is not associated with prenatal drug use; rather, low birth - weight is more common. Prenatal drug use does not cause longer term pregnancy.

Answer:

sudden infant death syndrome
