RT Journal A1 Volkow ND T1 IMpact of fetal drug exposures on the adolescent brain JF JAMA Pediatrics JO JAMA Pediatrics YR 2013 FD April 1 VO 167 IS 4 SP 390 OP 391 DO 10.1001/jamapediatrics.2013.556 UL http://dx.doi.org/10.1001/jamapediatrics.2013.556 AB Drug use during pregnancy, which in the United States is estimated at 1 million individuals each year,1 puts the newborn at increased risk for multiple adverse health outcomes. While the deleterious effects of alcohol, and to a lesser extent nicotine, to the fetus are well recognized, those of illicit drugs are much less understood. Drugs can harm the fetus both via effects to the placenta interfering with nutrient delivery and through direct effects to the fetus. Moreover, the high lipophilicity of drugs ensures that significant concentrations reach the fetus' brain and other organs.2 Thus, the consequences of fetal drug exposure on brain development and function, and ultimately on behavior, constitute an important area of research.
