► It is unclear why pregnancy is a salient motivator for changing substance use. ► Substance cessation during pregnancy may involve both altruism and self interest. ► We examined substance cessation in women who made postnatal adoption placements. ► Prenatal substance cessation was independently related to self concept as a provider. ► Depression, antisocial behaviors, and genetic factors may have inhibited cessation.
