The Cost of Not Preventing Crack Babies, N.y. Times, Oct. 10, 1991,
The Epidemic That Wasn't
BALTIMORE — One sister is 14; the other is 9. They are a vibrant pair: the older girl is high-spirited but responsible, a solid student and a devoted helper at home; her sister loves to read and watch cooking shows, and she recently scored well to a higher place average on citywide standardized tests.
At that place would be zip remarkable well-nigh these ii happy, normal girls if information technology were non for their mother's history. Yvette H., now 38, admits that she used cocaine (along with heroin and alcohol) while she was pregnant with each girl. "A drug addict," she now says ruefully, "isn't really concerned about the baby she's carrying."
When the use of crack cocaine became a nationwide epidemic in the 1980s and '90s, there were widespread fears that prenatal exposure to the drug would produce a generation of severely damaged children. Newspapers carried headlines similar "Cocaine: A Vicious Assault on a Kid," "Crack's Toll Amidst Babies: A Joyless View" and "Studies: Future Bleak for Fissure Babies."
Only now researchers are systematically following children who were exposed to cocaine before birth, and their findings suggest that the encouraging stories of Ms. H.'s daughters are anything but unusual. So far, these scientists say, the long-term effects of such exposure on children'south brain development and behavior appear relatively small.
"Are there differences? Yes," said Barry M. Lester, a professor of psychiatry at Brown Academy who directs the Maternal Lifestyle Study, a large federally financed written report of children exposed to cocaine in the womb. "Are they reliable and persistent? Yes. Are they large? No."
Cocaine is undoubtedly bad for the fetus. Merely experts say its effects are less astringent than those of alcohol and are comparable to those of tobacco — two legal substances that are used much more oftentimes by pregnant women, despite health warnings.
Surveys by the Department of Wellness and Homo Services in 2006 and 2007 establish that 5.2 percent of meaning women reported using any illicit drug, compared with 11.6 percent for alcohol and 16.4 percent for tobacco.
"The argument is not that it'south O.M. to use cocaine in pregnancy, whatsoever more than information technology's O.G. to smoke cigarettes in pregnancy," said Dr. Deborah A. Frank, a pediatrician at Boston University. "Neither drug is good for anybody."
But cocaine use in pregnancy has been treated as a moral issue rather than a health trouble, Dr. Frank said. Pregnant women who use illegal drugs commonly lose custody of their children, and during the 1990s many were prosecuted and jailed.

Cocaine slows fetal growth, and exposed infants tend to exist born smaller than unexposed ones, with smaller heads. But every bit these children grow, encephalon and torso size catch up.
At a scientific briefing in November, Dr. Lester presented an analysis of a pool of studies of xiv groups of cocaine-exposed children — 4,419 in all, ranging in age from iv to 13. The assay failed to testify a statistically significant effect on I.Q. or language development. In the largest of the studies, I.Q. scores of exposed children averaged most four points lower at age vii than those of unexposed children.
In tests that measure out specific brain functions, there is prove that cocaine-exposed children are more probable than others to have difficulty with tasks that crave visual attending and "executive function" — the brain's power to set priorities and pay selective attention, enabling the kid to focus on the task at mitt.
Cocaine exposure may also increase the frequency of defiant beliefs and poor conduct, according to Dr. Lester'due south analysis. At that place is also some evidence that boys may be more vulnerable than girls to behavior problems.
Just experts say these findings are quite subtle and hard to generalize. "Just because information technology is statistically significant doesn't mean that it is a huge public health impact," said Dr. Harolyn M. Belcher, a neurodevelopmental pediatrician who is manager of research at the Kennedy Krieger Constitute's Family Center in Baltimore.
And Michael Lewis, a professor of pediatrics and psychiatry at the Robert Wood Johnson Medical School in New Brunswick, N.J., said that in a physician'south function or a classroom, "you lot cannot tell" which children were exposed to cocaine before nativity.
He added that factors like poor parenting, poverty and stresses similar exposure to violence were far more likely to harm a child'due south intellectual and emotional development — and by the same token, growing upwardly in a stable household, with parents who do non abuse booze or drugs, tin do much to ease whatsoever harmful furnishings of prenatal drug exposure.
Possession of scissure cocaine, the form of the drug that was widely sold in inner-metropolis, predominantly black neighborhoods, has long been punished with tougher sentences than possession of powdered cocaine, although both forms are identically metabolized by the body and accept the same pharmacological furnishings.
Dr. Frank, the pediatrician in Boston, says cocaine-exposed children are often teased or stigmatized if others are aware of their exposure. If they develop physical symptoms or behavioral problems, doctors or teachers are sometimes too quick to blame the drug exposure and miss the real cause, similar illness or abuse.
"Society'south expectations of the children," she said, "and reaction to the mothers are completely guided not by the toxicity, but by the social meaning" of the drug.
Inquiry on the wellness effects of illegal drugs, especially on unborn children, is politically loaded. Researchers studying children exposed to cocaine say they struggle to translate their findings for the public without exaggerating their significance — or minimizing it, either.

Dr. Lester, the leader of the Maternal Lifestyle Written report, noted that the evidence for behavioral issues strengthened equally the children in his study and others approached adolescence. Researchers in the report are collecting data on 14-year-olds, he said, calculation: "Absolutely, nosotros need to continue to follow these kids. For the One thousand.L.S., the principal thing we're interested in is whether or not prenatal cocaine exposure predisposes y'all to early-onset drug use in adolescence" or other mental wellness problems.
Researchers take long theorized that prenatal exposure to a drug may make it more probable that the child will go on to utilize information technology. But so far, such a link has been scientifically reported only in the example of tobacco exposure.
Teasing out the furnishings of cocaine exposure is complicated by the fact that like Yvette H., almost all of the women in the studies who used cocaine while significant were as well using other substances.
Moreover, most of the children in the studies are poor, and many have other hazard factors known to affect cognitive development and behavior — inadequate health care, substandard schools, unstable family situations and exposure to high levels of lead. Dr. Lester said his group's study was large enough to take such factors into account.
Ms. H., who agreed to exist interviewed merely on the condition that her terminal name and her children'southward first names not be used, said she entered a drug and alcohol treatment programme about six years agone, after losing custody of her children.
Another daughter, born later Ms. H. recovered from drug and alcohol abuse, is thriving now at 3. Her oldest, a 17-year-old boy, is the only one with developmental problems: he is autistic. But Ms. H. said she did not use cocaine, alcohol or other substances while pregnant with him.
After xv months without using drugs or alcohol, Ms. H. regained custody and moved into Dayspring House, a residential program in Baltimore for women recovering from drug corruption, and their children.
There she received psychological counseling, parenting classes, job training and coaching on how to manage her finances. Her youngest attended Head Beginning, the older children went to local schools and were assigned household chores, and the family unit learned how to talk about their problems.
Now Ms. H. works at a local grocery, has paid off her debts, has her own house and is actively involved in her children's schooling and health care. She said regaining her children'due south trust took a long time. "It's something you take to constantly keep working on," she said.
Dr. Belcher, who is president of Dayspring's board of directors, said such programs offered show-based interventions for the children of drug abusers that can assistance minimize the chances of impairment from past exposure to cocaine or other drugs.
"I think we can say this is an at-take a chance grouping," Dr. Belcher said. "But they have great potential to do well if nosotros can mobilize resource effectually the family."
