Cannabis, a mixture of hundreds of cannabinoids, can cross the placental and blood–brain barriers and is excreted in breast milk. The fetal risks are serious, and the scope is wider than pregnancy alone as cannabis accumulates and has many weeks long duration of activity. Thus risks concern all women of child bearing age especially as many pregnancies are unplanned. This is a public health issue regarding societal wide levels of use; avoiding pregnancy exposure is not possible by women ceasing use just before becoming pregnant or in early pregnancy.
