From that article
Even big numbers are small numbers.
They studied data from 500,000 births. Of which 2,200 included mothers who said they used cannabis but not alcohol or other drugs. The incidence of autism was 4 per 1000, compared to 2.42 per 1000 for the control group.
That means there were 9 autistic kids, when they expected to find 5 or 6.
Is that really significant? I don't know. Is it?
Its also a correlative study. They reviewed medical records. They didn't actually experiment. Of course that's not the sort of experiment that I expect many people would participate in, or would even be approved.
