Question

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

Explanation:

When a mother uses drugs during pregnancy, it can have various negative impacts on the fetus. Allergies are not a direct consequence of prenatal drug use. High birth weight is unlikely as drug use often leads to low birth weight. Longer - term pregnancy is not a typical result. However, drug use during pregnancy has been associated with an increased risk of sudden infant death syndrome (SIDS). This is because drugs can affect the baby's development, including the development of the respiratory and central nervous systems, which are crucial for survival.

Answer:

sudden infant death syndrome
