After nearly 25 years of studying the effects of cocaine and publishing or presenting dozens of findings, it wasn't easy to summarize it in a PowerPoint presentation. The study received nearly $7.9 million in federal funding over the years, as well as $130,000 from the Einstein Society...

Hurt's study enrolled only full-term babies so the possible effects of prematurity did not skew the results. The babies were then evaluated periodically, beginning at six months and then every six or 12 months on through young adulthood. Their mothers agreed to be tested for drug use throughout the study.

The researchers consistently found no significant differences between the cocaine-exposed children and the controls. At age 4, for instance, the average IQ of the cocaine-exposed children was 79.0 and the average IQ for the nonexposed children was 81.9. Both numbers are well below the average of 90 to 109 for U.S. children in the same age group. When it came to school readiness at age 6, about 25 percent of children in each group scored in the abnormal range on tests for math and letter and word recognition.

As the children grew, the researchers did many evaluations to tease out environmental factors that could be affecting their development. On the upside, they found that children being raised in a nurturing home - measured by such factors as caregiver warmth and affection and language stimulation - were doing better than kids in a less nurturing home. On the downside, they found that 81 percent of the children had seen someone arrested; 74 percent had heard gunshots; 35 percent had seen someone get shot; and 19 percent had seen a dead body outside - and the kids were only 7 years old at the time. Those children who reported a high exposure to violence were likelier to show signs of depression and anxiety and to have lower self-esteem.

Other researchers also couldn't find any devastating effects from cocaine exposure in the womb. Claire Coles, a psychiatry professor at Emory University, has been tracking a group of low-income Atlanta children. Her work has found that cocaine exposure does not seem to affect children's overall cognition and school performance...

Coles said her research had found nothing to back up predictions that cocaine-exposed babies were doomed for life. "As a society we say, 'Cocaine is bad and therefore it must cause damage to babies,' " Coles said. "When you have a myth, it tends to linger for a long time."
