Science and Prenatal Drug Exposure Are There Drug Effects? YES, BUT: They are smaller than initially thought Not all drug exposed children are affected They can be treated

Medical Conditions(N>8,000) • Previously reportedmedical problems in the mothers were rare (<5%) and not related to cocaine • Previously reported physical damage to the infant was rare (<5%) and not related to cocaine
Medical Findings at Birth • Cocaine effects were found on infant gestational age (8.4 days), birthweight (536 grams) head circumference (1.5 cm), small for gestational age (29% vs 13%) • Cocaine exposed infants showed more “soft signs” and behavioral effects

What is the Cost to Society? 120,000 drug exposed infants/year X 5% (extra 6000 drug exposed children per year needing special education services) X $9204 (cost special education services per child) = $55,224,000 per year additional funds
Brown Oklahoma California Hawaii IDEAL Iowa Methamphetamine: Infant Development Environment And Lifestyle Study
Research Is Just Beginning According to an NIH Expert Panel Report: in terms of the potential adverse reproductive and developmental effects of meth exposure “studies that focused upon humans were uninterpretable” … …due to such factors as a lack of control of potential confounding factors and the issue of the purity and contaminants of the methamphetamine used by the drug abusers” (p.191). NTP-CERHR, Monograph on the Potential Human Reproductive and Developmental Effects of Amphetamines, July 2005
IDEAL: Medical Conditions(N=408) • No increase in maternal medical problems in mothers who used Meth during pregnancy (e.g. placental abruption) • No increase in physical damage in Meth exposed infants
Medical Findings at Birth • Meth effects were found on infant gestational age (1.4 weeks), birthweight (200 grams) and small for gestational age (19% vs 8.5%)
Newborn Behavior • Lower arousal • More stress signs • Similar to cocaine

Policy Responses 2 parallel policy responses towards drug use by women Punitive Treatment
Punitive • Drug use by mothers as legal/criminal issue • Criminal justice system - Child welfare system • Harming child by using drugs • Child abuse in its most destructive form • Favors imprisonment, child removal
Treatment • Drug use by pregnant women viewed as a mental health (medical) issue • Harm reduction • Reproductive health care, substance abuse and mental health treatment, relationship with child
Problems With Punitive Approach • Fear of being reported drives women away from health care system (e.g. prenatal care) • Denies the opportunity to parent for those who can/want to parent
Problems With Punitive Approach • Overburdens foster care system • Child’s ability to form attachments is jeopardized by multiple foster placements

Model Programs • Family centered • Comprehensive • Interdisciplinary staff • Nonjudgmental, nonpunitive, nurturing, culturally appropriate • Parenting programs • Mental health and women’s issues • Child care • Transportation
What Have We Learned? • Addiction is a disease – a medical condition that can be treated • Mothers don’t use drugs because they are evil people who don’t care about their baby • They use drugs because they have a mental disorder
What Have We Learned? Community Violence Violent Friends A bad environment can worsen drug effects Domestic Violence
What Have We Learned? • Environment is key A good environment can overcome drug effects

Current Headlines The Meth Epidemic: Hype vs Reality New drug wave delivers 'crank babies' Crack Then, Meth Now Generation of Meth Babies We are in a similar situation today with methamphetamine as we were 20 years ago with cocaine
Current Headlines meth babies” “could make the crack baby look like a walk in the nursery” Children of meth users are filling foster homes Meth Infants Called the New “Crack Babies” Only Future Will Tell Full Damage Speed Wreaks on Kids
Avoid Labeling Top Medical Doctors, Scientists & Specialists Urge Major Media Outlets Not to Create “Meth Baby” Myth Signatories from Leading Hospitals and Research Institutes In US and Abroad Agree That Term Lacks Scientific Basis as Does the Claim That Treatment Does Not Work July 25, 2005
Avoid Labeling “The use of stigmatizing terms, such as ice babies and meth babies, lack scientific validity and should not be used. Experience with similar labels applied to children exposed parentally to cocaine demonstrates that such labels harm the children to which they are applied, lowering expectations for their academic and life achievements, discouraging investigation into other causes for physical and social problems the child might encounter, and leading to policies that ignore factors, including poverty, that may play a much more significant role in their lives.”
Final Thought… We have made tremendous strides in the past 20 years when it comes to our understanding drug addiction and treatment. The effects of prenatal drug exposure are milder than initially thought. A good environment can help overcome drug effects.
Final Thought… While there are drug users who are inadequate mothers, there are also drug users who are competent mothers who, with treatment, can care for their children. Families can be preserved. Failure to take advantage of what we have learned is not only a missed opportunity but a giant step backward.
