The message that drinking and pregnancy poses considerable risk to the unborn fetus appears to be getting through. Over the last decade, alcohol use among pregnant women has decreased, according to a new report from the Substance Abuse and Mental Health Services Administration. More troubling, however, is that during that same 10-year period, illicit drug use among pregnant woman has seen a dramatic increase. The report shows that pregnant women who sought substance abuse treatment for alcohol with or without drug use dropped from 46.6 percent in 2000 to 34.8 percent in 2010. Pregnant women admitted for substance abuse treatment for drug use without co-occurring alcohol use increased to 63.8 percent in 2010, compared with 2000\u2019s 51.1 percent. But it isn\u2019t just pregnant women who are using illicit drugs more. The report showed similar patterns among women of child-bearing age who sought substance abuse treatment. In a summary, the report concludes that this may mean more attention needs to be focused on addressing drug use in this population. Risks of Illicit Drug Use in Pregnant Women What are some of the risks associated with illicit drug use in pregnant women? They vary by drug type, but here are some of the most common: Cocaine Adverse effects include: \tSmaller head circumference in cocaine-exposed infants \tLower birth weight and length \tIrritability \tPoor interactive abilities \tIncreased incidence of stillbirth, prematurity and sudden infant death syndrome (SIDS) Opioids Complications include: \tSpontaneous abortion, premature labor and delivery, premature membrane rupture, high blood pressure and intrauterine death. \tThe fetus is at risk for death due to the mother\u2019s episodes of withdrawal. \tFetuses exposed to opioids such as heroin and methadone have lower birth weights than unexposed fetuses and usually undergo neonatal abstinence syndrome at birth. Amphetamine, Methamphetamine Both short- and long-term effects result from exposure to amphetamine and methamphetamine, including: \tAbnormal growth of the fetus \tWithdrawal symptoms after birth \tImpaired neurological development in infancy and childhood \tAmphetamine exposure increases the risk of reduced fetal growth, heart anomalies and cleft lip and palate.
