CNN (8/10, Lamotte) reports, “In what they call the largest study ever done, researchers found using marijuana while pregnant may increase the risk that a child will develop autism.” The findings were published in Nature Medicine. One study author said, “Women who used cannabis during pregnancy were 1.5 times more likely to have a child with autism. … These are not reassuring findings. We highly discourage use of cannabis during pregnancy and breastfeeding.”

NBC News (8/10) reports that in the “analysis of data from more than 500,000 Canadian mothers and their children, researchers found a 50 percent increase in the risk of autism spectrum disorder in kids whose mothers had used cannabis while pregnant, according to the report.” Researchers “reviewed data from all Ontario births that occurred from 2007 to 2012, which was before the drug was legalized in Canada.”

MedPage Today (8/10, D’Ambrosio) reports that “hints of increased risk of intellectual and learning disabilities and attention deficit hyperactivity disorder (ADHD) were also seen, according to” the report.

Psychiatric News (8/10) reports, “During the study period, 2.2% of children with prenatal cannabis exposure were diagnosed with ASD, compared with a rate of 1.4% among all children.”
