Many studies have relied on the history obtained from the mother, which is notoriously inaccurate. In addition to recall bias, there is a considerable incentive to withhold information. Testing of urine for drugs of abuse does not reflect drug exposure throughout pregnancy and does not provide quantitative information. Many women who abuse drugs are multiple drug abusers and also drink alcohol and smoke cigarettes. It is thus difficult to isolate the effects of any one drug. Social and economic deprivation is common among drug abusers, and this factor not only confounds perinatal data but has a major effect on long-term studies of infant outcome.
