FLORENCE, Italy — Both mothers and fathers who use cannabis during pregnancy are more likely to have children who experience psychotic symptoms, new research suggests.
An analysis of more than 3500 families showed that maternal cannabis use was linked to a 38% increased risk for psychotic symptoms in offspring at 10 years of age; cannabis use among fathers was associated with a 44% increased risk....

Making any conclusions is very premature as this study is not anywhere near showing a casual relationship.
And the raw numbers seem very suspect to me:
3500 families yet:
"The team found that 183 mothers used cannabis; 98 did so before pregnancy, and 85 did so during pregnancy. In addition, 386 women continued tobacco smoking during pregnancy. Cannabis use was reported by 297 fathers."
??? Only 183 moms out of 3500 families used cannabis?? Tobacco was used by 386 moms during pregnancy--- which has a much worse effects on a fetus, etc.

"Commenting on the findings for
Medscape Medical News, Richard Saitz, MD, MPH, chair and professor, Department of Community Health Sciences, Boston University School of Public Health, Massachusetts, said that he hesitates "to draw any firm conclusions," because few details of the study have been provided and the study has not been fully peer reviewed.
"For example, we do not know how many children experienced psychotic symptoms, nor do we know what potential confounders were adjusted for, and the differences between the adjusted and unadjusted models seem minimal, which could either suggest there is little confounding to worry about, or that the right confounders were not included," he said."

The Jamaican study of cannabis and pregnancy showed no developmental differences between cannabis and non-cannabis kids at 1 day, 30 days, 4 years, 5 years and those were moms doing big ol' Jamaican ganja blunts--nasty combustion.
The posted study is very premature with many important details absent.
Think endocannabinoid system folks--even more important that the ECS has ample cannabinoids during pregnancy.
EDIT-- Jamaican Study addition: I said no difference in cannabis vs non kids BUT to be forthwright, the kids with cannabis moms came out better on some elements:
"Dr. Dreher and her team
compared babies of Jamaican women who smoked marijuana during pregnancy and those who did not. The researchers tested infants on a variety of functions one, three, and 30 days after birth. Their findings were surprising: cannabis-exposed babies scored significantly higher in their reflex tests as well as tests of basic functions like blood pressure and heart rate. The infants of cannabis-using moms were also less irritable and more alert.
Dreher’s team
then followed up with the children at ages four and five. The follow-up study used the McCarthy Scales of Children’s Abilities to test IQ and behavioral performances. It also took home environment, and school attendance into account. The team found no difference between children in the two groups."
Peace, out
